Device for producing homogeneous mixtures "of at least two mix components that are matched to one another in terms of quantity

The invention relates to a device for producing homogeneous mixtures of at least two on top of one another in terms of quantity matched aggregate components in a mixing container be mixed with a liquid, whereby the proportion of one is only small compared to the other, and relates in particular to such a device for producing a wafer dough mass; such a device is however, it is not restricted to this preferred use, but can also be used in the production of other types of dough or of spreads,

.like "for example fat cream, piidding cream, chocolate, Nougat or Karaiael mass, jam or cheese cream.

In all of these cases, a söLcnsa precaution! direction aimed to let this work automatically, and if possible, this was done in conjunction with upstream and / or downstream Units in a corresponding production line, such as an automatic wafer making line. Especially in this case it comes to both Throughput capacity of the entire wafer production line3, as well as for the quality of the waffles produced on this, is essential on the automatic dough stirring and mixing machines. Under an automatic dough mixer which has a represents a special type of generic device is Understood in the technical world such a device, the essential feature of which is that the Be concept components for the It keeps the dough mixed at the same time as it is metered into the Bührb. -.

Well-known automatic dough mixers work so far that the charging or mixing container is suspended from load cells, so that the recipe components are cheated, the The mixing time is controlled by a time relay. For emptying, the dough is automatically placed in a storage container pumped and from there to the wafer baking machines. The dosage in such known devices is either Gravimetrically, i.e. by feeding the dry components for dough production into the fiükrbshäiter, or by feeding 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 charge container content.

409850/0973

This known device has for throughput capacity as well as for the reproducibility of the quality of the end product, So for dia at & aa the rationalization aia most essential determining parameters, considerable disadvantages which than had to be accepted so far not to be switched off. The most important element for increasing the throughput capacity is that required with these known devices absolute sequential control, because the time required for adding a mix component has to be waited for must be until with the addition of the next mix component can be started. This is accompanied by the further disadvantageous need before adding the next one ■ Mix component to interrupt the mixing process in order to enable weighing of the mixed material, if one does not wants to accept the considerable constructive and cost-related as well as operational effort, considerable electronic Compens at ion circuits to have to make to the different '' Agitator speeds as well as different imbalances with different dough consistencies and thus to compensate for the accompanying incorrect deflection of the weighing device.

Wan hai = already tried here, thereby this essential Disadvantage of creating a remedy is that the individual mix components dissolved or puffed up in a suitable carrier liquid before feeding into the stirred tank; and then, aaai pre-store has supplied v / whether ei the Removal of the individual mix components to be floated was carried out volumetrically from the respectively assigned silo or bunker. Although this can mitigate the disadvantages, resulting from the gravimetric dosing in the mixing tank result, which among other things consist in the fact that the measurement accuracy even with the use of considerable compensation set-up effort from a purely theoretical point of view already proportionate

must be small, because the finest ingredients, which in the smallest Add traces based on an entire batch of mixes are, respectively, on the Suaiaa of all previous Zuai jcliuagsa be related, i.e. to the entire contents of the same already in the mixing container. This low measurement accuracy for small crane mixings of mix components, -which as ingredients to the whipped up essentially of flour and meat Relatively small amounts of dough make baking easier, promote browning and the crispness, the taste and should improve the quality as a whole, but experience has shown that it has a particularly disadvantageous effect on the Quality of the end product for which the dough composition and consistency as well as the freshness of the dough already exist in the entrance area of the production line for the end product is essential. The gravimetric metering of ingredients that have previously been brought to a liquid consistency can also be used here not to be of any help for theoretical reasons alone. This way out so far taken by the professional world has - rather a further significant disadvantage. It's over Reasons of efficient production as well as again necessary for reasons of sufficient measurement accuracy, at least in the Temporary storage for the dissolved or flooded Slainstiaengenzutaten a relatively large amount of a Additions tailored to a specific batch of dough bring to. In such a case, however, which experience has shown to occur more frequently in practical operation, should be done in between on the automatic :! Dough mixer a different dough recipe can be worked or processed, in which the small quantities are mixed. :. if required in a different composition, the content of this buffer is for liquefied Medium practically not usable for this. But this means that under certain circumstances it is precisely the remainder of this intermediate. Memory, which is not inconsiderable under certain circumstances, has to wait a long time for further processing,

- 5 -409850/0973

whereby it loses its freshness and becomes unusable. But in a large number of cases this is a considerable one economic loss not only in terms of the work involved in production. · ^ wischengelagertsn mixture, but also in particular with regard to the cost price of the mix components concerned, xfobei it must also not be disregarded that in such a pail also the one with the current one, no longer required mixes occupied intermediate storage as well as this assigned conveying or pumping devices for other 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,. Another Uachteil can not be excluded that each in different hygroscopic properties of ". Kischgutkompor-eiiten. has its cause, namely the both feeding in the same or in individual resolved dry .or in liquid bloated form and in the form of a Mixture of several such mixed material components dissolved or floated in liquid. Depending on these hygroscopic properties, the mixing container serving as a weighing pan suggests a different amount of dry matter with a given feed weight in the dissolved or flooded state. Compensation for a constant amount of dry material is even more complicated when used. Compensation electronics desvregen practically not possible because the measurement of the respective moisture content of the additive to be fed in is practically impossible to carry out in a sufficiently short time for practical continuous operation and on the other hand when the respective specified mixing weight of the fed in goods is reached and before it is fed into the

Mixing container already existing goods, the shutdown of the Feeding device for the respective feed material just wegsn. This Hessungeaauigkait not so fast and with can be switched off with a predeterminable overrun, that a predetermined follow-up amount of dry matter could be drawn into the scsipensation ax.

For all these reasons, in addition to the economic efficiency and · the simplicity of dough production, both its Eeproduzierbarke.it in and of itself as well as adherence to a predetermined dough recipe even with automatic dough preparation with a view to maximizing the dough quality 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 a possibility for the automatic production of mixtures of at least two quantity-balanced mix components, those in a mixing container with a liquid to be moved, ucd especially for automatic Mixing or stirring dough in the conventional sense is preferred of waffle dough, avoiding all of the described To create disadvantages of the known devices of the generic type and continue to be real fully automatic Operation, in the sense of a fully preprogrammed operation that is itself woken up via corresponding impulse circuits such a device, which is also task-related also easily, simply and quickly in a program control of the entire production line for a certain product, as Individual part of v / elcher such a device is used, intended to be inserted, to enable \ robei according to more specialized subordinate task a device

of the type mentioned should not only be improved so that it meets today's high requirements for constant operating conditions, which is trouble-free !. Sequence lait one ^; Once a recipe has been set and programmed, it should also exclude human error, but also a possibility should be created to prevent any adulteration effects from the dosing operation on the one hand or the mixing operation, in particular during dough production, on the other hand, and in particular the hygroscopic properties of the individual mix components and finally also the Shutdown process of the feed of the same total and / or liquid mix components in the mixing container and thus a previously unattainable capacity increase is achieved.

According to the general inventive concept on which the invention is based This is achieved through the cumulative application of two measures that are already known for themselves in other applications achieved, namely on the one hand by the fact that according to the invention the metering process is separated from the mixing process, i.e. metering and mixing is carried out simultaneously, but at a different point, and that on the other hand the dosage In contrast to the state of the art, it is not carried out gravimetrically, but volumetrically. In this way, according to further task desired for some purposes Possibility created with relatively little, constructive and cost-related effort while maintaining the described advantages or overcoming the disadvantages described

409850/0973

of the prior art device, the mixing vessel in addition to the movement of the mixer members themselves subject to a hotationa or even tumbling motion can, provided that for. should be considered necessary, without affecting the dosing accuracy and thus the dough quality from the point of view of the same unfavorably influenced.

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, whereby the proportion one is only small compared to the other, for example to produce a Uaffel dough mass, in that one The number of silos corresponding to the number of mix components are provided for storing them in a dry state and each silo is assigned a discharge device which volumetrically determines the desired extraction quantity, and that this Extraction devices with their extraction constrictions in a dry state directly to a common conveying device, by means of which the respective withdrawal quantities of the mix components the mixing container can be guided.

According to its expedient development of the invention, the conveyor device can be designed as a dry conveyor. This makes the conveying device relatively inexpensive and avoids the disadvantages resulting from the dissolution of the Fei as buildatan, and in particular the often disadvantageous influence of different solvents for these mix components on the finished baked goods. As a further improvement, the conveying device can also be designed as a premixer for at least two of the mix components. In this way, a particularly good approximation of the desired continuous mode of operation, which cannot be achieved in the prior art, can be achieved. At the same time, ·.

409850/0973

also the influence of the individual mixture components on the toughness of the mix, such as the dough, see better behorr, al ζ this "in devices according .com: a. the art is possible case, a simple ■ conveyor belt to some extent can already considered. Such premixers are used, but a vibrating conveyor or a conveyor belt with an associated vibrating device can also be used.

According to a further inventive development, several Hish container be provided, the conveyor for v / ahlweise delivery to one of the same is designed to be switchable. In the state of the art it is. not possible, two mixing containers to be loaded with a scale. But this also means that two different mixes can be produced at the same time excluded, such as two doughs, one with added oil and the other with added fat ■ is produced, or what different coloring on- · v / iron. It is the first time through this inventive idea possible, which are always required. To take advantage of mixed calls that during the mixing process of a mixing container the metering into another and / or the mixing process in the latter can take place without additional costly metering devices and associated additional devices, such as pumps or the like, as well as additional intermediate containers would be required in which the once in Emulsification carried out in larger quantities by again complex devices such as agitators or the like, heating devices for temperature control, to be constantly maintained nut. In the present inventive idea, the For example, in large systems that have to produce different baked goods at the same time, the desired time

Offset of the M ropes mixture in separate mixing tanks lower capacity for the first time with the simplest hit leg economical, achieved. '' -

The temporal utilization of a device according to the invention for the Produltiοnoyteig3 rung "with simultaneous quality improvement can thus be used in a further useful JTort-, "Improve formation of the invention that the! 'table-top container at the same time Liquid material and mixed material components can be supplied.

According to another, the invention in an unobvious way • Perfecting training can help improve that volumetric dosing of the mix components the extraction devices jev / eils one below the assigned silo. Have arranged measuring chamber. The measuring chamber can be stationary be designed and have an emptying opening, which can be closed by one of its walls designed as a flap or slide, preferably the bottom. But it has proven to be both for constructive reasons as well with a view to a particularly precise and yet relatively fast dosage proved to be useful if the Measuring chamber designed as a segmentr = un a swiveling drum whose filling opening is in the discharge position at the same time Emptying opening is. The swivel drum can therefore expediently have several measuring chambers.

In an advantageous embodiment the MeEskammsr can regard to their Aufnahmevo; clumens- be adjustable to a pre-once handene device according to the invention by simple engagement in a ödere several of the trigger means by way of adjustment of the Messkammervoluaens easily and quickly to different formulations to be able to customize. In the case of a stationary measuring chamber, this can be formed by two tubular wall parts that overlap in the manner of a sleeve, one of which is silo-fixed and on both sides

This can be advantageous one of the Vandungs see nice 1 on a pivot shaft and the other wall legs set on a Yerstellnuffe be made by changing the lissskamiaervoluBicns relative is rotatable to the pivot point. Special constructive simplifications also result from the fact that the wall legs along their edge remote from the pivot axis each have one corresponding to the Inner contour of the cover housing3 curved in a cylindrical shape Have cover flap and that on the right, the undocking flag of a swivel shaft fixed wall wall with the cover overlaps a flag of a wall leg that is adjustable in angle relative to this. At the same time it is done with simple Give a good seal ^ i ^ lreit to the landing of the cover housing achieved through which it is avoided that the poss continuous solidification of deposits, which interferes with the drive between the wall legs delimiting the measuring chamber and the inner wall of the "cover housing," which lead to blockages of the swiveling movement of the measuring chamber or to compressions which falsify the measurement result of the mix comes. . - '

Thus, according to the invention, not only the disadvantages of the prior art become apparent the technology with regard to the accuracy of the dosage in particular also with a view to avoiding flow through in the ItLs chb, which at the same time forms the scales. existing residues from the previous mixed batch avoided, but also the process control with laehrersn Iliochchargen possible with a time offset to one another, with volumetric metering taking place in the manner described in this figure . a moisture-independent dosing, in particular that which has a significant influence on the quality of the baked goods Finest ingredients is made possible, with the fact that several Messkainaern in spring trap are considerably cheaper than the stand several scales that are indispensable for technology, quite apart from the considerable Significance for the Ilesskaamern having the possibility of synchronizing or Hessbecher. :

According to another inventive development, the adjusting sleeve relative to a reference part fixed to the swivel shaft, which is preferably designed as a single flange, adjustable be, with adjustment sleeve and / or Bszugteil markings for the display c-ss respective. KesskaHunervoluaens or have opening angle between wall legs. In this way, observation or monitoring is very easy of the individual measuring chamber volumes from the outside without intervention ia those who form the measuring chambers and their volucre ru-svsrstellung effecting mechanism possible.

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

rotatably arranged and can be coupled with this via a detachable driver connection. It can expediently the rii b η 2ha ervero charge be designed as a switching clutch, v / srin here - which is particularly suitable for large units is - large measuring cartridges are motor-driven, whereby then preferably one responsive to electrical scarf tirapulae 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 locking screw, by means of which a twisting movement between the intermediate sleeve and the swivel shaft can be blocked. This possibility, the driver connection in the Course of the kinematic chain from the swivel drive for the /. To interrupt the swivel drum towards the swivel drum, serves in addition, for the purpose of adapting the individual existing extraction devices or their measuring chambers to specified ones. Recipes the extraction devices each except for a single one to be set in terms of their measuring chamber volume turn off. This makes a valuable contribution to the perfected mastery of the the invention underlying task of enabling the greatest possible degree of automation while adapting to the Conditions of the upstream and / or downstream units and inserted into their program-controlled process flow.

Special constructive no procedural simplifications' also result from the fact that the pivot axis at least several, preferably all, measuring chambers through all common kingship is formed. Furthermore, it has also been found to be useful if at least one side is used Part of the cover housing is mounted in a silo-fixed manner so that it can be swiveled away from the measuring chamber drum. In this way a Option for quick and easy cleaning of the measuring chamber

created in the event that this is especially after a long time Use or because of changes to the silo content required should be"

To further perfect the invention with a view to achieving a high level of KessgenauigicGit and producibility the metering rate in particular in comparison to the amount of the main constituent part of the mix with the smallest mix components is provided according to a further idea of the invention that by means of the withdrawal device the withdrawal amount each practically independent of the static pressure of the silo contents can be removed from the silo. For this purpose, it is advisable to the height of the column dos silo contents above the filling opening of the discharge device must be limited. This is done 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 sit or without the interposition of a Belt conveyor, a chute or the like can be charged. This Zwisctaskarsaer can outside of the SiIo outer wall be arranged, with a vibrator device nit the silo outer wall is in direct contact. In such a case, the costs for an intermediate housing part usually have to be borne, which is arranged underneath the silo exit so that it is caused by the vibratory movements imposed on the silo outer wall is not affected, and it is because of the immediate Influence on the relatively strong outer wall of the silo mostly use relatively powerful vibrators. Still, has this further development of the invention its advantageous intended use, and especially wherever existing systems interact with existing silos to be retrofitted with a device according to the invention ·.

409850/0973

In newly created devices according to the invention it is mostly preferable to carry out this according to another the J-irf charge further developing 2 "O. 3rf indungsgedaul-can, -which is characterized by the fact that at a distance from the. . The bottom of the silo has a funnel-shaped interior '-J -.- iiscxiOiiwand with you in proportion "ur silo outlet opening small feed opening is provided, with which a vibrator device is in operative connection. The manufacture of the silo and its adaptation to the associated deduction system easier and cheaper here, especially since the ones to use. dung reaching vibrators can usually be designed to be smaller.

In the operation of a device according to the invention it is sometimes desired to be able to take samples for control purposes, be it to determine the consistency and / or quantity of one or more ■ To check mix components, be it to adjust the individual extraction devices to the desired extraction quantity to adjust. In order to create a simple possibility for this, the conveying device can expediently in the sense of Loading of an overflow chute can be reversed.

To increase the dosing accuracy with equilateral The invention also provides for an increase in the quality of the mixed material, a further measure for improving the invention. Device compared to the prior art, according to x ^ elcher in non-obvious ex-veins as a volumetric suction device for liquid or viscous mix components, in particular for fat or oil, each one without a suction valve A piston pump with a shear point is provided between a shear edge of the piston and a shear edge of the suction opening, whose piston stroke is adjustable between an idle position and a maximum stroke position. So far, as deduction devices for such media also piston pumps

- 16 -

409850/0973

used, but these had a suction valve in addition to the suction valve. As a result, "both valves had to be coordinated with one another, not inconsiderably, in order to enable the piston pump to work accurately, and that inspections were also required in relatively short periods of time, - often due to the consistency of the media to be pumped to "adjustments of the two valves against each other, and that then-Kachsaugeffekte _t occurred, which led to falsifications of the dosage, which was expressed in negative influences on the mixing ratios between these mix components and the other mix components, in particular the fine aggregates. Apart from the fact that this inventive measure of using a suction valve piston pump with a shear point on the suction side, regardless of the setting of the piston stroke and thus the dosing amount, makes it possible to determine this dosing amount in a reproducible manner without delaying the coordination of two valves with one another The fact that after-run phenomena or harmful pressure influences on the pump medium are avoided, because such a piston pump provided according to the invention creates the possibility that excess cylinder content is always flooded back into the pump medium silo, such a design is also considerably more cost-effective to produce and also more economical to operate .

In order to continue to contribute to the dosing accuracy that in the case of dry components of the liiscligut ^ residues of the same.-in the trigger devices are avoided, 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 the adhesion of the respective mix component for example in the form of a cover "by PalyhaLa.genääiy3Leii, preferably polyirerized tetrafluorathylerr, or one Chronic or a layer of enamel!

- 17 -A09850 / 0973

In order to continue to eliminate falsifications of the mix composition in other stables, the invention can be provided according to an advantageous continuation, since ^; 3 dar liischbanält a by means of a ^. f edärloadaten G-raphitringee has self-sealing bearing of a mixing blade. The term Klschflügel is understood to mean not only a stirrer, but also a cutting mechanism which, in addition to circulating and mixing, also punctures the crushing of etxiaiger solid constituents, such as jam pieces in a device according to the invention used as a spreading mixer, or of lumps or the like in the case of a device used as a wafer dough grinder, takes over. In this case, a bearing carrier can advantageously be provided which is held in a leak- proof manner with respect to the Ilischbehäiter and has a sealing surface on which the graphite ring, which is supported by a spring sleeve relative to a covering hood rotating with the mixing vane shaft, runs. In this way it is ensured that, despite the use of mixing containers with "container-fixed agitators, that is, with a filling opening free of agitator parts, the areas where a certain bearing play is unavoidable due to the necessity of a selective rotation of two ropes to each other" is avoided that proportions of mixed in the mixing tank. Mix components emerge unintentionally from the mixing container and thus the desired ratio of the mix components fed later to the previously mixed components, determined by the recipe, is falsified »·

Furthermore, the invention for the first time offers the possibility of a device of the type described the mixing container ' in the opposite direction to a mixing blade arranged in it itself to be rotatable. This can be used for good mixing acquire great importance in certain formulations.

The smallest opening angle and thus the smallest Ilesskaii yaw volume is given "when the adjacent surfaces of the respectively assigned wall legs 71, 72 or 73-74- lie on top of one another, which corresponds to an opening angle of 0 °. The respective opening angle οι or thus the respective measuring chamber volume can also be observed from the outside by assigning the arrow 87 to the “scale 88”.

For the purpose of checking the adjustment, the non-rotatable connection between intermediate sleeve 79 and shaft 10 can also be canceled by loosening the locking screw 83 (KLg · 5). From an operational point of view, this means that this trigger device no longer follows a drive movement of the shaft 10 as long as the locking screw 83 is not tightened ISt ₁ and therefore another trigger device can be checked.

The suspension or production of this locking connection between intermediate sleeve 79 ″ and shaft 10 can also be motorized or remotely operated and take place during the operation of the device according to the invention.
