such as fat cream, pudding cream, chocolate, Nougat or caramel mass, jam or cheese cream.

Such a device is used in all of these applications endeavored to have these work automatically, and SHSfHr to do so, if possible, in conjunction with upstream and / or downstream Aggregates in a corresponding production. i line, such as an automatic wafer making line. It is precisely in this application that both the throughput capacity of the entire wafer production line and also essential for the quality of the waffles produced on this on the automatic dough mixer or dough mixer · Under an automatic dough mixer, which is a represents a special type of generic device, such a device is understood in the technical world, whose An essential feature is that the recipe components for dough production are added to the dough at the same time Can be mixed.

Known automatic dough mixers work so far that the drilling or mixing container is suspended from load cells so that the recipe components are weighed, the mixing time being controlled by a time relay. To the When emptied, the dough is automatically pumped into a storage container and from there to the wafer baking machines. Me Dosing in such known devices takes place either gravimetrically, i.e. by feeding in the dry components for the dough production in the charging container, or by adding Solution of the same after their dissolution in a liquid carrier medium, in each case in such a way that the mixing container itself serves as a weighing pan in which one component is added after the other by weighing is always additive to the entire contents of the stirred tank.

This known device has for the throughput capacity as well as for the reproducibility of the quality of the end product, So for the two most essential parameters determining the rationalization, considerable disadvantages, which one than had to be accepted so far not to be switched off. The most important index-uis for a. " Increase in the throughput capacity = Zität is the absolute pole control required in these known devices, because the for the admixture of a Mixing material component it is essential to wait until the next mixing material component is added can be started. This is accompanied by the further disadvantageous need before adding the next one Interrupt the mixing process in order to allow the mixed goods to be weighed if you do not wants to accept the considerable constructive and cost-related as well as operational effort, considerable electronic To have to make compensation circuits in order to be able to Agitator speed menu. as well as bsi. different 3? Eigfciissis * e5 £ * e * i ΐΐϋΐθΓβΛΚίΑΑΙχβ ^ βη, imbalances en and thus to compensate the associated misalignment of the ^^ device.

Attempts have already been made here to make this essential The disadvantage of remedying this is that the individual mix components before being fed into the agitator tank, it is dissolved or suspended in a suitable carrier liquid and then fed to a preliminary storage facility, with the removal of the individual niche material components to be floated volumetrically from the respectively assigned silo or bunker. Although this can mitigate the disadvantages, which result from the gravimetric dosing in the MiscK older, which among other things consists in the fact that the measuring accuracy even with the use of considerable effort to set up compensation from a purely theoretical point of view already proportionate

Must be minor, because the painful ingredients, which in the least Add traces based on an entire batch of mixes are based on the total of all previous admixtures, i.e. the total already in the mixing tank located content of the same. This low measurement accuracy for- Eieiüstseügsnzuiaischencn of mix components ^ which as ingredients for the dough, which is essentially made up of flour and water, make baking easier in relatively small quantities, to promote tanning and improve the crispness, taste and quality as a whole, "affects According to experience, however, it is particularly disadvantageous on dxe Quality of the end product for which the dough composition and consistency as well as the freshness of the dough already in the entrance area of the production line has a significant influence on the end product. The gravimetric one can also do this here The addition of ingredients that have previously been brought to a liquid consistency does not help, even for theoretical considerations. This way out so far taken by the specialist world has vifilmeh ,? another major disadvantage. It's over Reasons of efficient production as well as again necessary for reasons of sufficient measurement accuracy, at least in the Intermediate storage for the dissolved or floated small amount ingredients a relatively large amount of a to bring in admixtures tailored to a specific batch of dough. In such a case, however, which experience has shown to occur more frequently in practical operation, should be done in between Another dough recipe can be processed or processed on the automatic dough mixer, in which the smallest quantities are mixed: in a different composition: is required, the content of this intermediate storage is for liquefied Medium practically not usable for this. But this means that under certain circumstances it is precisely the contents of this buffer, which, under certain circumstances, is not inconsiderable, has to wait a long time before it can be further processed,

whereby it loses its freshness and becomes unusable. But in a large number of cases this means a considerable one economic loss not only in terms of the work involved in the production of this in the intermediate storage interim mixture, but also in particular with regard to the cost price of the respective mix components, in addition, it should not be left out of consideration that in such a case the one with the currently no longer the required mix as well as the conveying or pumping devices assigned to it for other purposes Use are occupied, so that the constructive and operational effort for these units is added negatively.

However, even if it is possible to process the entire content of such a buffer, a further disadvantage cannot be ruled out, which is the various hygroscopic properties of the individual mix components have their cause; and this both when feeding the same in individual dry or dissolved or floated in liquid form as well in the form of a mixture of several such mix components dissolved or suspended in liquid. Depending on these hygroscopic properties, the mixing container serving as a weighing pan is given a different amount of dry matter with a given feed weight in the solution or Suspended state fed. A compensation to constant The amount of dry material is therefore practically not possible even when using complicated compensation electronics, because the measurement of the respective moisture content of the additive to be added in for practical continuous operation Practically not feasible for a sufficiently short time and, on the other hand, when the respective specified mixture weight is reached of fed-in goods and before it is fed into the

Mixing container already existing material, the shutdown of the feed device for the respective feed material Also because of this measurement inaccuracy, it cannot be switched off so quickly and with a predeterminable lag, that a predetermined overrun amount of dry matter could be included in the compensation.

For all these reasons, in addition to the economy and the simplicity of dough production, it is also easy to reproduce in and of itself as well as compliance with a predetermined batter recipe, even when the batter preparation process is automatic with a view to maximizing the quality of the dough and in Depending on this, not only the mode of operation of the downstream units, but also that achieved with them Quality of the end product in need of improvement.

The invention is generally based on the overriding object of providing a possibility for the automatic production of mixtures of at least two mix components that are matched to one another in terms of quantity, which are mixed with a liquid product in a mixing container, especially for automatic ones Mixing dough or stirring dough in the conventional sense, preferably of wafer dough mass, avoiding all of the above Disadvantages of the known devices of the generic type and continue to be real, fully automatic Operation in the sense of a fully pre-programmed and appropriate Pulse return lines self-monitored operation of such a device, which is also tasked also easily, simply and quickly in a program control of the entire production line for a specific product, as Individual part of which such a device is used, is intended to be inserted, to enable, being specialized in accordance with erer subordinate task a device

of the type mentioned should not only be improved in such a way that they meet today's high requirements for constant operating conditions that guarantee a trouble-free process with a recipe that has been set and programmed once is sufficient and exclude human error, but also a possibility should be created to prevent any adulteration effects from the dosing operation on the one hand or from the mixing operation, especially when making dough on the other hand, and in particular the hygroscopic properties of the individual mix components and finally also the shutdown of the supply of the same to Switch off the mixing container in such a way that a maximum of metering accuracy even with the smallest admixture amounts of the individual mix components in relation to the total amount of the Mixing batch on the one hand and also the simultaneous dosing and dosing, which is not possible according to the state of the art Several dry and / or liquid mix components are fed in in the mixing container and thus one not yet for achievable increase in capacity is achieved.

According to the general inventive concept on which the invention is based this is achieved through the cumulative application of two for itself already achieved in other use of known measures, on the one hand by the fact that according to the invention Dosing process is separated from the mixing process, i.e. dosing and mixing at the same time, but at different rates Place is made, and that on the other hand, in contrast to the prior art, the dosage is not gravimetrically, but rather is made volumetrically. In this way, according to another object, the one desired for some purposes becomes Possibility created with relatively little effort in terms of construction and costs while maintaining the described Advantages and / or overcoming of the disadvantages described

of the prior art device also includes the mixing vessel in addition to moving the mixing members themselves subject to a rotational or even tumbling motion can, if this should be considered necessary, without affecting the dosing accuracy and thus the dough quality from the point of view of the same unfavorable to influence.

According to the invention, a device for generating homogeneous mixtures of at least two one on top of the other is characterized in terms of quantity Matched mix components, which are mixed with a liquid product in a mixing container, wc> .ei the proportion the one compared to the other is only small, for example to produce a wafer dough mass, in that one j number of silos corresponding to the number of mix components

According to an expedient development of the invention, the conveyor device can be designed as a dry conveyor. Through this the conveyor device is relatively inexpensive on the one hand, and the disadvantages are avoided on the other hand> resulting from the dissolution of the finest ingredients, in particular, the often disadvantageous influence of different solvents' for this.

Particularly in the case of a drying conveyor designed as a conveyor belt, the belt speed can increase or decrease rapid feeding of the dry matter to the mixing container can be effected.

According to a further development of the invention, several mixing containers can be provided, the conveying device being designed to be switchable for optional delivery to one of the same.

Relocation of the mix in separate mixing containers with a lower capacity for the first time with the simplest of means Achieved economically.

iüe temporal utilization of a gate direction according to the invention for the increase in production with a simultaneous improvement in quality this can be used in further practical training improve the invention that dwa mixing container at the same time Liquid material and mixed material components can be supplied.

According to another development which does not improve the invention in an obvious manner, the extraction devices can each have a measuring chamber arranged below the assigned silo in order to improve the volumetric metering of the mix components. The measuring chamber can be designed to be stationary and have an emptying opening which is eXxucwSu ifSSuuugSIIj VOi.uugän * cxSS uSu juGuSuj VS3? SCjj.a.iS * <ii ^ SiX * XSv. However, it has proven to be useful, both for structural reasons and with regard to a particularly precise and yet relatively fast metering, if the measuring chamber is designed as a segment space of a swivel drum, the filling opening of which in the emptying position is at the same time an emptying opening. The swivel drum can therefore expediently have several measuring chambers.

In an advantageous further development, the measuring chamber can be adjustable with regard to its accommodation volume in order to accommodate an existing one Device according to the invention by simple intervention in one or more of the trigger devices to be able to adapt quickly and easily to different recipes by adjusting the measuring chamber volume, In the case of a fixed measuring chamber this by means of two pipe-shaped tubes that grip each other like a socket Wall parts be formed, one of which is silo-proof and on both sides

open and the other down through flap or slide is closed and to change the heas chamber volume telescopically slidable relative to the wall part fixed to the silo and is detectable.

In the case of the extraction device being formed as a swivel drum with segmented spaces as heas chambers, the ness chamber can advantageously be formed by two tongue-like wall legs which are angularly adjustable in their angular position by pivoting against each other about a common axis, which are in a drum-like cover housing by rotating together about the common axis of a filling opening flanking a filling opening in each case can be pivoted into an emptying position flanking an emptying opening in this respective filling opening. One of the Vandungsschenksl on a pivot shaft and the other Wa & dusgsschenksl on a Vsrstellauffe can be fixed. Change of the Hesskammervolume is rotatable relative to the pivot shaft. B ^. ^ Other structural simplifications result from the fact that the wall legs along their schwenkechsferaen band each have a cylinder jacket-like curved cover flap corresponding to the inner kcatur of the cover housing and that each of the cover flaps of a swivel-shaft-fixed wall leg with the cover flap of one opposite this angle versteJ ! Baren Wandungsschenkeid overlaps. At the same time, a good seal against the wall of the cover housing is achieved with simple coats, which avoids that the continuously operating deposits ^j rfirmungen between the W 'delimiting the Hesskammer. u.

Thus, according to the invention, not only the disadvantages of the prior art with regard to the accuracy of the metering are in particular also with a view to avoiding interference Avoided by buck stands from the previous mixed batch that are present in the mixing container that simultaneously forms the weighing pan, but also the process control with several mixed batches possible with a time offset to one another, with volumetric metering taking place in the manner described a moisture-independent dosing in particular also has a significant influence on the quality of the baked goods Finest ingredients is made possible, with the fact that several measuring chambers in spring case are considerably cheaper than the indispensable multiple scales in the state of the art, not to mention the possibility of synchronization for the measuring chambers, which is of considerable importance for the simplification of the traversing control or measuring cup.

According to another inventive development, the adjusting sleeve relative to a reference part fixed to the swivel shaft, which is preferably designed as a Bing flange, be adjustable, with adjustment sleeve and / or reference part markings for the display of the respective measuring chamber volume or opening angle between wall legs. In this way, a very simple observation or monitoring of the individual measuring chamber volumes from the outside is without intervention in which the measuring chamber forming and its volume adjustment causing mechanism possible.

Furthermore, it has been found to be particularly expedient when to fix the wall leg fixed to the pivot shaft on the pivot shaft and the support part for the adjustable wall leg relative to the pivot shaft one to the pivot shaft coaxial intermediate sleeve is provided on the pivot shaft

rotatably arranged and via a detachable driver connection can be coupled with this. The entrainment connection can expediently be designed as a clutch if here - which is particularly suitable for large units - large measuring chambers are driven by a motor, whereby then preferably one that responds to electrical switching pulses Clutch is used. However, this driver connection does not need to be designed as a clutch rather, it can also be formed by a simple plague adjusting screw, by means of which a twisting movement can be blocked between intermediate sleeve and pivot shaft. This possibility, the driver connection in the To interrupt the kinematic chain from the swivel drive for the swivel drum to the swivel drum, is used in addition, for the purpose of adapting the individual existing extraction devices or their measuring chambers to specified ones With the exception of a single recipes, the extraction devices each have to be set in terms of their measuring chamber volume turn off. This makes a valuable contribution to the perfected mastery of the underlying the invention. Abandonment of enabling Extensive automation with simultaneous adaptation to the conditions of the upstream and / or downstream units and inserted into their program-controlled process flow.

Special constructive and procedural simplifications result from the fact that the pivot axis at least several, preferably all, measuring chambers is formed by a vertical shaft common to all · Furthermore, it also has calibration It has been found to be expedient if a part of the cover housing can be pivoted away from the measuring chamber tube at least on one side is stored in a silo. In this way there is namely a possibility for quick and easy legging of the measuring chamber

Created in the event that this is necessary in particular after prolonged use or because of changes in the contents of the silo should be.

To further perfect the invention with regard to Achieving a maximum of measurement accuracy and reproducibility the metered addition, especially in comparison to the amount of the main constituent of the mix of the smallest mix components is seen according to a further idea of the invention, that by means of the discharge device the withdrawal amount is practically independent of the static bridge of the silo = the contents of the silo can be removed. For this purpose, the height of the column of the silo contents above the filling opening can expediently the deduction device be limited. This happens according to the invention in that an intermediate chamber, which is open towards the filling opening of the extraction device, is provided above the same is which from the silo via a feed opening is proportionate small cross-section with or without the interposition of a belt conveyor, a chute or the like can be charged. This intermediate chamber can be arranged outside the silo outer wall, a vibrator device with the silo outer wall is in operative connection. In such a case, the cost of an intermediate housing part is usually to be borne, which is arranged below the silo exit in such a way that it is caused by the vibration movements imposed on the silo outer wall is not influenced, and it is mostly because of the direct influence of the relatively strong outer wall of the silo use relatively powerful vibrators. Nevertheless, this development of the invention has its advantageous intended use, in particular wherever existing systems work in conjunction with existing silos to be retrofitted with a device according to the invention.

O

In the case of devices to be newly created according to the invention it is usually preferable to carry out this according to another inventive idea that further develops the invention, which is characterized by the fact that at a distance from the bottom wall of the silo in its interior a funnel-shaped Intermediate wall with the feed opening, which is small in relation to the silo outlet opening, is provided with which a vibrator device is in operative connection. Lie production of the silo and its adaptation to the associated discharge device easier and cheaper here, especially since the vibrators used are usually designed to be smaller can.

In the operation of a device according to the invention it is sometimes desirable to be able to take samples for control purposes it to the consistency and / or amount of one or more To check the mix components, be it to adjust the individual extraction units *> n to the desired withdrawal amount to adjust. Jm here- for an easy way to create the conveying device can expediently be reversible in the sense of loading an overflow chute.

To increase the metering accuracy while increasing the quality of the mix, the invention provides a further measure to improve the device according to the invention compared to the state of the {Dechnik, according to which, in an unobvious way, as a volumetrically operating take-off device for liquid or viscous mix components, in particular for fat or oil , in each case a suction valve-less Eolben pump with a shear point between a shear edge of the Eolben and a shear edge of the suction opening is provided, the piston stroke of which is adjustable between an idle position and a maximum stroke position. So far, piston pumps have also been used as extraction devices for such "media"

- 16 -

used, but these had a suction valve in addition to the suction valve. As a result, the two valves had to be coordinated with a considerable amount of work in order to enable the piston pump to work accurately, and that inspections were necessary in relatively short periods of time because the consistency of the media to be pumped often led to adjustments Both valves came against each other, and that then single suction effects occurred, which led to falsifications of the ' dosing amount, which was expressed in negative influences on the mixing ratios between these mix components and the other mix components, in particular the finest aggregates. Apart from the fact that this inventive measure of the use of a; suction valve-less piston pump with shear point on the suction

side independent of the setting of the piston stroke and thus the dosing amount it is possible to use this dosing amount without need the coordination of two valves to one another is reproducible

] to be defined in such a way that after-run appears or is harmful

Influencing the pressure of the pump medium can be avoided, namely because such a piston pump provided according to the invention creates the possibility that excess cylinder contents are always poured back into the pumping means silo, Such a training is also considerably cheaper to create and also more economical to operate.

ITm furthermore to contribute to the dosing accuracy by the fact that in the case of dry ice components of the mix, residues of the same are avoided in the trigger devices, it is proposed in a further expedient development of the invention that the Inner surfaces of the measuring chambers each have a coating that at least reduces adhesion of the respective mix component for example in the form of a coating of polyhaloethylene, preferably polymerized tetrafluoroethylene, or one Chrome plating or an enamel layer.

- 17 -

In order to continue to eliminate falsifications of the mix composition elsewhere, according to FIG Continuation of the invention be provided that the mixing container by means of a spring-loaded graphite ring having self-sealing storage of a Miachflügel. file is not only an I & Lafwefk under mixing paddle, but also understood a cutting mechanism, which in addition to the circulation and mixing also the function of crushing any solid components, such as jam pieces in a gate direction used as a coating mix according to the invention or of lumps or the like in a gate direction used as a wafer batter mixer, takes over. In this case, a bearing support that is held non-rotatably and leak-tight with respect to the mixing container can advantageously be used be provided, which has a sealing surface on which the over a spring sleeve opposite one with the Mixing vane shaft rotating hood falling graphite ring runs. In this way it is ensured that, despite the use of mixing tanks with a fixed agitator, i.e. with the filling opening free from agitator parts, also the places where the mix is impermeable because of the necessity a-r- relative rotation of two parts to each other a certain bearing play is inevitable, which avoids that Proportions of mix components mixed in the mixing container unintentionally escape from the mixing container and so through the recipe determined the desired ratio of the mix components added later to those already mixed beforehand is adulterated.

Furthermore, the invention for the first time offers the possibility of using the mixing container in a device of the type described to be designed to be rotatable in opposite directions to a mixing blade arranged in it. This can be used for good mixing become of great importance in certain recipes.

The invention also makes it possible for the first time for the mixing container to move out of a working position with its drive is designed to be tiltable into an emptying position. This is often of considerable importance for smaller systems, in which the material to be mixed is not emptied by means of a suction pump via a stationary emptying nozzle or an emptying nozzle that is fixed to the mixing container is withdrawn from this, but by simply * tilting the mixing container from this is emptied · After the Such possibilities were not available in the state of the art

To further perfect the solution underlying the invention Tasks can be provided according to a further not obvious idea of the invention that at least one Plttssiggutzuuehr to the mixing tank, preferably a water supply, than arranged in the area of the upper edge of the mixing container on its walls or a cover that closes it line with the liquid against the

directing outlet nozzles is formed. In an inventive Device with counter-rotating to a mixing wing jdröhbar Mixing container can expediently discharge the liquid product into the spray ring via a fluid duct that is coaxial to the axis of rotation of the mixing container To solve this subordinate inventive concept, the quality of the mixing is surprisingly required considerably, because the liquid is forced to stick to the inner wall of the mixing container to trickle down and right there where the Heigang for lump formation or flatbread is greatest by rinsing of the mixed material components from the container oil surface to ensure that these mix components are distributed evenly in the mix and local concentrations largely avoided

It is still possible to reduce mixed batches as far as possible be provided that the inner surface of the mixing container a coating that at least reduces the adhesion of the mixed material for example in the form of a coating of polyhaloethylene, preferably polymerized tetrafluoroethylene, having.

In order, in particular when the device according to the invention is used in large-scale systems, to enable the object on which the invention is based, the device according to the invention to be easily, conveniently and quickly adapted to work programs of the units connected upstream and / or downstream by its own V « rf is ahrens flow controlled according to program, advantageously each Abzugseinrichtuns may be assigned its own drive, which with the take-off device, preferably via a responsive electrical Schaltimpuse clutch brought into operative connection is _e in this way, it is ensured that the Schaxtimpulse by simply changing depending on the desired PROGRM ^ ·., ■ which also includes the desired composition of the mix according to the recipe chosen, which one or the other mix components in the sense of a supply to the mixing container can be switched on or off at all or in terms of quantity. However, due to the number of independent drives for the individual extraction devices, this embodiment of the device according to the invention is relatively expensive. This disadvantage can be avoided by another development of the invention, according to which a positive coupling of at least several, preferably all, trigger devices with a common drive can be seen, in which case the drive with one or more of the trigger devices, preferably via an electrical one in each case, to create the program variability Switching impulses

responsive clutch can be brought into operative connection can. So here a single sufficiently powerful drive is provided, which in the vast majority of Cases will be cheaper than a multitude of smaller ones

To further perfect the device according to the invention with regard to its insertability in a program-controlled working production line can according to a through the Invention itself for the first time enabled inventive advanced training a program control device with a programmer and a pulse generator controlled by this for supplying the switching pulses for the program-controlled supply or disconnection of the operative connection between the drive and the associated trigger device may be provided. Here can expediently the programmer of the program control device by means of program carriers in the form of interchangeable programs Program cards can be operated.

Above the mixing container 1 there are four dry material silos 11, 12 _t 13 »14, each with an associated discharge device 21 or 2 or 23 or 24, which contain the individual mix components A or B or C or * D * Kass assumed be that in this gate direction designed as a mixer for wafer dough mass according to the invention, the mix component: D is the flour used as the main component, while A, B and D each symbolize the other components to be mixed in considerably smaller ^ quantities, such as soda, ammonium , Salt, sugar, milk powder, egg powder, soybean flour, potato flour, silk powder, corn powder, lecipan or the like. All of the discharge devices 21 to the silos 11 to 13 work on a common conveying device 3 ″ which is designed as a chute. This chute 3 is used due to its mode of action as a premixer for the mix components A, B and C.
