Description

Technical field

The utility model relates to equipment for baking and confectionery production, namely, to devices for making dough.

Such devices, as a rule, contain a kneading machine for mixing the components and kneading the dough mass in a special container (bowl), as well as devices for unloading the finished dough from the bowl.

State of the art

A known device for the preparation of dough manufactured by TBM TECNOPAST BAKERY MACHINES S.P.A. (Italy) - a number of models of the EU SR series (see the Spiral Mixers brochure, information on the website www.tecnopast.com). This device has the largest number of features common with the claimed utility model, and is selected as its prototype.

The device comprises a kneading machine with a stationary bowl and a hydraulic tipper, designed to lift and tilt the kneading machine, while the bowl installed on it is tipped over and thus the dough is unloaded.

The dough mixing machine contains an electric drive and a spiral kneading organ located vertically in the head of the machine. In the phase of mixing the components and kneading the dough, the bowl is covered with a protective grill. The purpose of this grill is to ensure the safety of the operator by not allowing him to come into contact with moving parts of the device. An attempt to raise the grill at the time of operation of the dough mixer leads to a lock and stops the dough mixer. When loading components into the bowl and when unloading dough from the machine, the protective grill is raised and does not interfere

loading and unloading. Kneading and unloading of dough are controlled from a common control panel.

The prototype is an example of modern test preparation equipment, ingeniously combining in one device with a single control system the functions of kneading and unloading dough.

However, the prototype has several disadvantages.

All the ingredients necessary for preparing the dough have to be loaded into the stationary bowl either manually or using dispensers, feeders and other loading devices, controlled separately from the dough preparation device. This creates serious obstacles to the implementation of the so-called "pairwise" dough preparation technologies. In such technologies, the components of the dough (flour, water, yeast) are first mixed: either on separate equipment (for example, on a dough mixer with a rolling bowl), or in a stationary bowl of a dough preparation device. Until ready, the mixture should stand for a sufficiently long time until the fermentation process takes place. So that the dough mixing equipment does not stand idle at this time, in the first case, the bowl is rolled out from the dough mixing machine, and in the second case, the resulting mixture is unloaded from the stationary bowl of the device into a separate bowl. Then the finished dough is loaded from a separate bowl into the stationary bowl of the dough preparation device, additional components are added there (the rest of the flour, salt, sugar, spices, fats and other ingredients according to the recipe) and the final dough is kneaded. The prototype does not solve the problem of loading the dough into the stationary bowl of the kneading machine; to implement this operation, manual labor or the use of additional equipment is required.

Due to the fact that in the prototype the loading of components is carried out in an open bowl, some of the liquid components are inevitably sprayed or

spills past the bowl. Fine powdery components (flour, dry yeast, etc.) rise into the air, forming suspensions that settle on the floor, walls, equipment of the bakery, and penetrate the respiratory organs of workers. Not to mention the adverse effect of this factor on the health of workers, it is necessary to take into account unproductive losses of the initial products, and unjustified labor costs for additional cleaning of the premises.

When unloading the dough, there is a need to clean the bowl from the remnants of dough adhering to its walls. The prototype does not provide any devices for this. This laborious operation has to be done manually, which significantly increases the labor costs of the bakery staff and the time of forced downtime.

Utility Model Implementation

A dough preparation device comprises a dough mixing machine 1 with a dough unloading device 2, a dough loading device 3 and a control panel 4.

A kneading organ is vertically located in the head part of the kneading machine, a bowl 5 is fixedly installed on the bed, the machine has electric drives for rotating the kneading body and bowl.

Above the bowl of the kneading machine there is a lid 6, which compacts the bowl when loading the components and kneading. On the lid there are nozzles 7 designed for connection with flexible hoses of external devices for loading the dough components 8. The presence of the lid and nozzles avoids spraying and splashing of the loaded components outside the bowl. To observe the process of mixing the components and kneading the dough in the lid has a viewing window.

A scraper 9 is mounted on the head of the dough mixing machine, which is located at the inner surface of the bowl perpendicular to the direction of its rotation. It is intended for cleaning the inner surface of the bowl from particles of mixed components and dough.

The device for unloading the dough 2 is configured to overturn the dough mixing machine 1 with the stationary bowl 5. It contains a hydraulic drive, a frame and a lever. A roll-out bowl 10 is intended for receiving paged dough.

The device 3 is designed to load pre-cooked dough from the rolling bowl 10 into the stationary bowl 5 of the dough mixer. It contains a hydraulic cylinder, operating from the hydraulic station of the dough unloading device 2, a frame, a locking device, a loading platform 11.

The platform is made with the possibility of fixing a rolling bowl on it, lifting and flipping.

The control panel 4 is electrically connected to a dough mixing machine, a dough unloading device and a dough loading device with the possibility of coordinated control of them.

The preparation of the dough-free technology test in the inventive device is as follows.

Through the nozzles 7 with the lid 6 of the kneading machine 1 closed, the bowl 5 is loaded with the necessary raw materials from the component loading device 8.

On command from the control panel 4, the test cycle is started. Kneading machine mixes the components and kneads the dough. In this case, the scraper 9 removes particles of the mixed mass from the walls of the bowl, directing them to the zone of active mixing, where the kneading organ rotates.

After the signal about the end of the batch cycle has been triggered, the lid 6 is opened, after which, upon a command from the control panel, the unloading device 2 lifts and turns the dough mixing machine with bowl 5, unloading the dough into a rolling bowl 10.

After unloading the dough, the rotation drive of the bowl 5 is turned on and with the help of a scraper 9 the inner surface of the rotating bowl is cleaned of the remaining dough, which also falls into the rolling bowl.

Upon completion of cleaning, the dough mixing machine is transferred by the device 2 to its original position. The cycle can be repeated.

Similarly, on the dough preparation device, you can mix the components of the dough (flour, water and yeast), transfer the mixture to a rolling bowl 10 and leave it there for the time necessary for fermentation.

In the case of preparation of the test using the pairwise technology, the rolling bowl 10 with the cooked bowl (previously on the same device or on other equipment) is fixed on the loading platform 11 of the loading device 3. By lifting and turning the platform with the bowl, the pair is overloaded from the rolling bowl 10 in a stationary bowl 5 of a kneading machine. Then close the lid 6 and through the nozzles 7 in the bowl additionally load the flour and other components provided by the recipe (salt, sugar, fats, etc.), after which the kneading and unloading of the finished dough described above is started.

Thus, the claimed device for the preparation of dough is optimally suited for the implementation of pairwise test technologies, which are very popular in Russia and several foreign countries. At the same time, it allows the use of a fleet of widespread rolling bowls with a capacity of 330 liters for transporting dough and dough, standing dough and fermenting dough after final kneading (if such a technological operation is available).

Depending on the production necessity and the technological process used, various options for additional equipment for the dough preparation device are possible - for example, various component loading devices (dispensers, feeders). If necessary, it is not difficult to dismantle the device and provide autonomous operation of the dough mixing machine.

The combination of several functions (loading the dough, mixing the components, kneading the dough and unloading it) in one device significantly increases its functionality and productivity, reduces material consumption and labor costs during operation.

A prototype of this device was manufactured and tested, tests showed the achievement of the claimed technical results in the implemented utility model.
