Description

The proposed utility model (hereinafter - PM) refers to equipment for the production of dumplings, specifically, to mince feeders.

Known mince feeder, including a bunker, a blower and a distributor of minced meat, containing at least one channel (meat pipe) for supplying minced meat to a dumpling machine (see, for example, RF patent for PM No. 104425). The disadvantage of the known feeders is that when using natural beef fat, which is necessary for making high-quality dumplings, the fat, cooled to almost zero temperature according to the requirements of the food standard, sticks to the walls of the meat pipeline, creating fatty plugs. As a result, a reduced dose of minced meat can get into the dumpling, which reduces the quality of the product. In practice, fatty plugs are fought by heating the meat pipe.

The closest to the proposed PM is, in our opinion, a device for supplying minced meat according to the patent of the Russian Federation No. 156895 - a prototype. In the specified device, flexible heating elements (heating elements) are wound on the meat conduit. The heaters are connected to a source of electric current. During operation, the minced meat is pumped through a meat pipe heated by heating elements, then the minced meat enters the dumpling machine through the lantern.

The disadvantages of the prototype include the inconvenience of maintenance and low efficiency. The problem is that flexible heating elements, which, when washing the feeder, need to be unwound from the meat pipe each time, periodically receive mechanical damage. At the same time, disassembling the heater and assembling it takes additional time and effort. In addition, during operation, part of the heat is released into the atmosphere, which leads to undesirable energy losses and a deterioration in the working conditions of the operator.

The technical task is to increase the efficiency of the stuffing feeder and the convenience of its maintenance.

The technical result is achieved by the fact that the minced meat feeder for the dumpling machine, including the minced meat hopper, the minced meat pump, the minced meat pipeline for supplying minced meat to the dumpling machine, the electric heater containing the heating winding connected to the power supply, is characterized in that the minced meat pipeline contains an inner pipe for minced meat, which is placed inside the outer protective tube, and the specified winding is wound on the inner tube, while the meat conduit is provided with thermal insulation, which is superimposed on the electric heater winding.

In the feeder, the electric heater winding is made of a wire, including a conductive core made of high-resistance wire, on which heat-resistant electrical insulation of a heat-conducting material is applied. The feeder is equipped with a programmable electronic unit for controlling the operation of the electric heater connected to the power supply. The feeder is equipped with an electric heater winding temperature sensor, which is connected to the specified electronic unit.

The device of the utility model is illustrated by drawings. In FIG. 1 shows a general view of the mince feeder, Fig. 2 is a close-up view of A from FIG. one.

In an example of a specific execution, the mince feeder contains a hopper 1 communicated with a mince pump 2 having a drive 3. The output of the pump 2 is connected with a mince line 4, which is removable to simplify washing and sanitizing the feeder. The pin 5 is used to supply minced meat to the dumpling machine.

Meat conduit 4 includes an outer tube 6 made in the form of a protective housing. In the pipe 6, an inner pipe 7 for minced meat is laid. A heating winding 8 is wound on the pipe 7 from a wire with a conductive core made of a high-resistance alloy of the nichrome type. The wire has a heat-resistant insulation that conducts heat. Thermal insulation 9 is superimposed on the winding 8, which is located inside the housing 6. The temperature sensor 10 is built into the housing 6, which has thermal contact with the heating winding 8. The housing has an electrical connector (not shown) for connecting the winding 8 to the power supply 11. The arrow indicates mince flow direction.

The sensor 10 is connected to a programmable electronic unit (PEB) for controlling the heater (built into the source housing 11). On the PEB panel there are indicators of the current strength in the winding 8 and the temperature level of its surface (not shown).

Minced meat feeder works as follows. To prepare the feeder for operation, the inlet of the meat pipe 4 is connected to the outlet of the pump 2, the pin 5 is connected to the outlet of the meat pipe. The winding 8 is connected by a power cable to the power supply 11. The sensor 10 is connected by a signal cable to the PEB input (not shown). Then turn on the power of the electric heater and gradually increase the current through the winding 8. The current heats the winding 8, which is controlled by the sensor 10. The PEB contains a relay that turns the current in the winding 8 on and off, stabilizing the temperature of the winding at the desired level. In this case, the inner tube 7 of the meat pipe is heated to the set temperature.

At the same time, natural minced meat with beef fat, cooled according to the standard, is loaded into the bunker. After the pipe 7 is warmed up, pump 2 is turned on, which starts pumping the minced meat into the pipe 7. When the minced meat comes into contact with the heated pipe 7, the edges of the pieces of fat in contact with the hot walls of the pipe melt, forming a thin layer of lubricant. As a result, the minced meat stream, which is cooled in its mass, easily slides inside the pipe 7 and is fed through the pin 5 into the dumpling punching machine. Ready-made dumplings, formed with chilled minced meat in accordance with the requirements of the standard, are then sent for freezing.

The PEB block automatically maintains the temperature of the heater 7. If the temperature drops below the set level, the signal from the PEB sensor turns on the current through the winding 8. At the same time, the walls of the pipe 7, heated to the desired temperature, melt a thin layer of adhering fat, ensuring the passage of minced meat without the formation of fatty plugs and fullness of doses of minced meat in dumplings.

The proposed feeder has a number of advantages in comparison with the prototype. In the feeder, the heating winding is located inside the protective housing. The meat tube can be easily removed for washing without fear of damaging the winding (increased convenience and safety). The presence of thermal insulation reduces heat loss, which increases efficiency and improves the working conditions of the operator. The use of a temperature sensor and a programmable control unit allows you to optimize energy consumption by automatically maintaining the temperature of the heater at the desired level (increasing efficiency). In this case, the heater is turned on only for a while in order to melt a thin layer of fat adhering to the pipe walls. This liquid layer becomes a natural lubricant, on which pieces of fat slide and are carried away by the minced meat. Thus, the self-cleaning of the meat pipeline occurs without heating the mass of minced meat. At the same time, minced meat with beef fat remains cold according to the standard, ensuring good taste and quality of dumplings.

According to the scheme described above, a prototype minced meat feeder for a dumpling machine was made. Tests showed good results.

The device is proposed for protection by a utility model patent.
