Description

This invention relates to complex bread making facilities and can be used in the baking industry.

The purpose of the invention is to increase the productivity of the bakery production process through the integrated mechanization of technological operations and the reduction of material and labor costs.

Supplying the device with a grain storage elevator located in the upper part of the room, the metering and weighing units, the primary processing line and the grinding of grain with a wire and a set of milling rollers with sieves successively located under the elevator make it possible to simplify transportation of the processed product along the processing line and reduce costs time and electricity, i.e. to increase the productivity of the process, since the movement of the product occurs under the action of gravity and does not require additional transporting equipment.

Supply the elevator with a spiral heat exchanger associated with a conveyor cooling device and augers

for mixing and feeding the grain into the metering unit, it allows to increase the productivity of the process, as it ensures the uniformity of the product supply for processing

The presence in the warehouse equipment of shelves for containers with cuts allows to reduce the costs of loading and unloading, i.e. reduce labor costs in the production of bakery products.

Providing the plant with a device for cooling the conveyor reduces the time required to prepare the device before sending the dough pieces to a baking oven, thus increasing the productivity of the process. Performing a billet in the form of a centrifuge with a fixed vertically vane working body reduces the maintenance costs of the equipment, since such a structure is more reliable in operation and provides high-quality product separation during processing.

Supplying the plant with a transport tunnel under the floor of the production room and a vertical transport pipe located in the center of the production room and connecting the weight unit of the primary processing and grinding of grain and the transport tunnel makes it possible to ship the grain to the means of transport.

The bakery plant includes a production room 1, having the shape of a circle, in the center of which is placed a baking oven 2 with a conveyor 3 for moving dough into it, made in the form of a ring mounted for rotation, as well as successively installed dough mixing machine 4, devices 5 for unloading bakery warehousing equipment, including shelving 6 placed in sectors 1 for containers 7 with finished products. The conveyor 3 is equipped with a device 8 for cooling it. An elevator 9 for storing grain is located in the upper part of the production area 1, below it is the metering 10 and 11 weight units, the primary processing line and the grinding of grain, which includes a roller 12, a set of milling rollers, respectively, 13 and a fine 14 grinding and sieve 15. The elevator 9 is equipped with a spiral heat exchanger 16 connected with the fixture 8 for cooling the conveyor 3 and has screws 17 for moving and feeding the grain to the dosing unit 10. The storage equipment contains racks 18 for containers 19 with a cut and associated means

0 conveyors 20 and 21 and the hopper 22 with the winding 12 and the sieves 15, at the outlet of the kneading machine 4 there is a device 23 for lubricating the conveyor with vegetable oil.

5 Bil 12 can be made in the form of a centrifuge, having a body 24, in which a paddle tool 26 is mounted on a vertical shaft 25.

The bakery plant can be equipped with a transport tunnel 27 located under the floor of the production room 1, and a vertical transport pipe 28 located in the center of the production room 1 and connecting the primary processing and grinding unit 11 of the grain processing line and the transport tunnel 27. The conveyor 3 consists from two technological lines for baking bread.

The bakery plant works as follows.

The grain stock is stored in the elevator 9, where it is periodically mixed and dried when the heat exchanger 16 and screws 17 are turned on. For under 5 ecchi, the grains for processing include the screws 17 and open the elevator window by a certain amount using the metering unit 10. The grain flows by gravity to the weight node 11 where happens

0 it is weighed, after which the mass of grain is sent to the fork 12, where the grain is separated from impurities, which are poured onto the conveyor 20. Pure grain enters the milling rollers 13 of coarse

5 grinding the grain, after which the wholemeal flour is poured onto the sieve 15 for sifting. From here, the wholemeal flour can be transferred to the rollers 14 for finer processing or supplied

0 directly to the kneading machine 4 for making dough. The bran is diverted from the screens 15 and, as well as the impurities from the 12, are poured onto the conveyor 20, from where they enter the bunker 22. From

The 5 bunkers of bran and other waste are put into containers 19 placed on a belt conveyor 21. Bran containers 19 for bran are moved under loading conveyor 20 as they are filled and then loaded into

vehicles. In the absence of vehicles, containers with cuts can be stored in the relevant sector of production area 1 on racks 18.

Depending on the technology, the dough mixing machine 4 receives flour of coarse or fine grinding. At the same time water and necessary spices are supplied to it. The prepared dough is squeezed through the spinnerettes of the kneading machine 4 onto the conveyor 3 and simultaneously cut into pieces of the same mass. The dough is extruded in the form of a tape of a certain profile. Before placing the dough, the conveyor 3 is lubricated with vegetable oil from the tool 23. Upon further movement of the conveyor 3, the dough enters the oven 2 and is baked. When exiting the oven 2 by the device 5, the finished bread is reloaded onto a belt conveyor and then loaded into the vehicles containers 7 and shipped to consumers. In the absence of vehicles, the bread containers 7 can be stored in the corresponding sector of the production room 1,

With further rotation of the conveyor 3 falls into. a device 8 for cooling the conveyor 3. This is necessary to prevent the oil and dough from sticking to the surface of the conveyor 3, since immediately after the device 8 there is a kneading machine 4 of another production line. Heat from tool 8 is used to dry the grain in the elevator 9 through its spiral heat exchanger 16.

If necessary, grain from elevator 9 can be loaded directly into vehicles. For this purpose, a transport pipe 28 is installed in the center of the production room 1, through which the metering unit 10 is poured into transport vehicles that enter the tunnel 27. formed under the floor of the production room 1.
