Kneading and / or mixing machine

The invention relates to a high-performance kneading and / or mixing machine with a trough which can be rotated in both directions and at different speeds and which is located on one of the working !! the machine chassis is releasably _$ in the retracted are formed in non-positive connection of the chassis and thus of the trough with the drive actuating the kneading and / or Miechwerkzeuge. Kneading and mixing machines with a rotatable tub and a kneading arm that protrudes into the tub are already known. The Knetaxa normally has a round cross-section, and the part protruding into the trough is spiral-shaped.In these machines, the Enetarm sweeps over the central axis of the trough in order to cover parts of the trough bottom in such a way that no kneading material collects in the middle part of the trough bottom. which is not detected and unlocked by rom tool - so 4as sweeps over gn

a relatively large area, so that a correspondingly high amount of energy must be expended. But there is one very important to this high rlo advance payment required so working with such AI mixing and kneading machines are uneconomical. Around To eliminate these difficulties, it is already known to use the leading edge of the knitting tool in the area between the top of the trough and the bottom of the trough. However, this reduces the kneading work, so that the preparation of the dough takes a longer time. But this in turn is in the case of an industrial production of baked goods disadvantageous.

Through scientific experiments it was found that by increasing the kneading speed and the kneading intensity can achieve a better baking quality. Thus, an increased kneading intensity results in a better and faster one Opening up the various flours, with ventilation of the dough, al ro a "certain" Rau e ^ a-fr nf fern fiih-r, in the Yeast propagation and thus with the Gar ν ^ rT. on a crucial one Role play. Further advantages of this so-called intensive kneading consist in an optimal dough yield with shorter production times (kneading and dough resting times).

The Khetintensität a processing machine is essentially on three factors dependent;

a) the number of revolutions of the kneading tool,

b) the kneading resistance of the kneading tool and

c) the shape of the kneading kettle.

High speeds of the kneading tool in interaction with a large radius of the same, however, lead to one

excessive heating of the dough. To pass one to prevent the permissible dough temperature and thus damage to the driving forces of the dough, are known in the case of Systems surround the boilers with water coils and are thus cooled to the desired temperature. These measures However, they are relatively expensive.

The invention is based, inter alia, on the problem of eliminating the shortcomings of the known machines listed above. The invention is also based on the object of proposing a kneading and washing machine in which the relative Speeds of the kneading tools to be processed Let change dough, in which the tools in the trough are designed to be retractable and extendable, and in which the trough can be moved in a simple manner, so that the kneaded material can be fed to different processing stations.

This and other tasks and requirements which can be seen from the foxgenaen description are never a solution, as in a kneading and / or mixing machine of high performance with a trough which can be rotated in both directions and at different speeds and which is located on a chassis that can be detached from the drive part of the machine is located, in which with a force-fit connection of the chassis and thus the trough with the drive part, the kneading and / or mixing machine suction are designed to be retractable, according to the invention a rotatable kneading and / or mixing width in the working position of the trough to approximately the bottom of the trough ranges, and is disposed eccentrically to its axis of rotation while a second at rest relative to the drive part of the machine and extends at the lower end with a Leitschar provided tool also to about sum soil Ces trough and disposed between the rotation axis of the trough and the rotating tool and the upper am outer housing part of the machine b is efestigt, WEL

ches up to the self-developing guide, roughly a cuboid Has cross section and is twisted in such a helical manner in the direction of its longitudinal axis that the subsequent Leitschar to the sphere of action of the rotating tool runs approximately tangential or the. Sphere of activity cuts.

According to the invention, the rotatable tool consists of a rune steel which is helically or helically shaped, the lower spiral section of which strokes during the rotary movement at a minimal distance over "part of the trough bottom and over the upper edge of the guide blade. Among other things, according to the invention To achieve the greatest possible kneading intensity with a relatively low electrical connection power, the trough radius is greater than the diameter d of the effective circle of the rotatable tool. The rotatable tool can advantageously be operated at several speeds. The kneading and / or mixing tools can be operated more advantageously In and out of the tub by means of motor power, it is possible to remove the tub from the drive and tool part of the machine even when it is loaded that is frictionally connected to the drive part of the machine ssig connect.

To enable fully automatic operation, the control of the entire machine can be remotely located Control panel.

According to the invention, the guide coulter is designed so that the material to be kneaded with the same direction of rotation of the trough and of the kneading tool the kneading tool with one to the bottom of the trough

directed component is fed to promote this process, the guide coulter is at the lower end with a equipped with an enlarged guide surface.

For a more detailed explanation of the basic principles of the invention, an exemplary embodiment, which is shown in the drawing is shown, described in detail. Here show:

Figure 1 is a side view of the kneading and / or mixing machine according to the invention, in which a part of the trough is shown in section and

Figure 2 is a plan view of the trough with the kneading tools in a schematic representation.

According to FIG. 1, the trough 1 is located on a chassis 2, which in turn is positively connected on a mount 3 to the lower drive part 4 of the stationary inner part 5 of the kneading and / or mixing machine. With the help of a pivotable lever 6 that can be operated with the foot, the chassis 2 is locked on the carriage 3 - The upper part 7 of the kneading and / or mixing machine can be extended upwards by means of a drive, not shown in detail, «ie through the" Dashed illustration 7 ^1. A rotatable kneading and / or mixing tool is attached to the upper part 7, which in the working position extends approximately to the bottom 9 of the trough 1, which is arranged eccentrically to the trough rotation axis 1o. A second relative to the drive part of the machine The stationary tool 11 is firmly connected to the upper part 7 and in the working position also extends approximately to the bottom 9 of the trough 1 and is arranged between the axis of rotation 1ü of the trough and the axis of rotation 12 of the rotatable tool 8 »The tool 11 which is stationary relative to the upper part 7 has a substantially cuboid cross-section and is twisted helically in the direction of its longitudinal axis at 13, BQ that di e located in the lower part of the tool 11

The rotatable tool is advantageously spiral or helically shaped and is preferably made of round steel. However, the invention is not limited to the use of round bars limited. The lower spiral section 16 of the rotatable tool S strokes during the rotary movement of the same at a minimal distance over parts of the trough bottom 9 and over the upper edge 17 of the guide share 14-, if this is the area of activity 15 of the rotating tool cuts.

According to the invention, the trough radius r is greater than the diameter d of the sphere of action 15 of the rotatable tool. This ensures that the kneaded material is processed intensively within a certain spatial area of the trough 1 with a relatively low amount of energy. In order to feed the kneading material to this area of the room, is it dormant? Tool Λ ^Λ provided,

which has a surface shape serving this purpose. ess

Since ⁷ SiCh in the present case ujä is a kneading and / or mixing machine of high performance, which is able to process a relatively large amount of kneaded material, correspondingly large forces act on the stationary tool 11. In order to still ensure stability and in order to prevent the stationary tool 11 from breaking off, it is rigidly connected to a pronounced console 18 located on the upper part 7, for example by means of screws. For this purpose, the stationary tool 11 is provided with a flange 19 at its upper end. Below the flange 19, the tool 11 merges into a cuboid cross-section, the cross-sectional longitudinal axis of which is directed towards the axis of rotation 12 of the rotatable tool 8. This makes it possible according to the invention to choose a cross-section of such a size that sufficient stability is given in each case. A

The decisive problem of the present invention is that, if such an alignment c 3 tool 11 is continued into the trough, an excessively large contact surface of the dough to be processed on the tool 11 would arise H n would result. For these reasons, according to the invention, the tool 11 is twisted at 13, whereby the contact surface of the dough on the tool 11 is reduced, while on the other hand a suitable surface guidance is advantageously created. Any amount of dough can then be processed, which is fed through the guide surfaces of the tool 11 to the processing area of the retiable work The remaining part of the tool 11 has an enlarged area 14. The axis of this surface 14 can now be guided as a tangent to the sphere of action 15 of the rotatable tool 8, or it can also intersect this sphere of action as a secant. By appropriately shaping the lower spiral section 16, an advantageous interaction of these two tools is achieved.

-β.

The tools, which are eccentrically arranged relative to trough 1 8 and 11 now make it possible in an advantageous manner to operate Jass even when the protective grille 2o is closed, i.e. during the Operation of the machine, a certain part of the trough 1 is accessible without .jedoch the operator pime can be reached by hand. In this way, for example, ingredients can be added to the kneaded material during the processing process without having to switch off the machine and without impairing the safety requirements will.

In order to enable remote control on the one hand, and to ensure easy access to all actuating elements on the other hand, given the size of the machine, a control panel 22 is provided, which is electrically connected to the kneading and / or mixing machine via a cable connection Γ 3. The control panel contains all the necessary control and switching elements that are required to operate the entire machine. These include, for example, a timer and a program control that meets all the requirements of a universally applicable kneading and / or mixing machine.

The trough 1 can now be moved in both directions and preferably also rotate at different speeds. On the other hand, since the trough 1 is on a chassis 2, according to the invention a non-positive and easily detachable connection provided between the chassis 2 and the lower part 4.

After, for example, the kneading and / or mixing process has ended is, the upper part 7 is moved to the position shown in dashed lines 7 ', so that then the trough with his

Assigning several troughs 1 to the mixer, so that the machine can be used efficiently according to the invention.

The arrangement of the kneading tools within the trough in Connection with the guide share according to the invention, favored when the trough is rotated clockwise on Figure 2, a rapid mixing of, for example, flour and water, since the solid material through the shape of the Guide surface Ί4- and through the spiral rotation from bottom to top is lifted from the bottom of the trough 1. When the mixing process is finished, the trough is turned in the opposite direction, with which an intensive kneading and efjie good air flow is made possible and favored. This can be achieved through the formation of the guide share and the corresponding direction of rotation of the trough The kneading material does not evade during processing by the kneading tool, while on the other hand there is sufficient stability of the tools is guaranteed. Another advantage of the invention is that the fact that the guide share only extends to the axis of the trough is enough, a relatively large space in the trough is available for loading and unloading the kneaded material. Through the With the geometry of the kneading tools, a high number of revolutions is possible with a relatively low motor power. This will make the Advantageously, the fermentation process in particular is accelerated, and the dough can also be better worked up guaranteed and the volume increased significantly, so that the ready-to-bake product also improves in terms of taste will.
