(54) DEVICE FOR THERMAL PROCESSING OF MEAT PRODUCTS

The invention relates to devices for the heat treatment of meat products and can be used in the meat industry, especially in the production of smoked sausages. A device for heat treatment of sausages is known, which contains a chamber with distribution and suction ducts. Ij A disadvantage of the known device is that it is impossible to regulate the air velocity, which is not. allows to conduct the processes of sludge, smoked and dried meats in the optimal mode. The purpose of the invention is to control the air velocity in the chamber. This goal is achieved by the fact that a device for heat treatment of meat products, containing a chamber with distribution and suction ducts, is equipped with a recirculation duct connecting the distribution and suction ducts, with an adjustable damper and a cooling duct installed in the recirculation duct. the device makes it universal, allows optimally to carry out all the stages of heat treatment, which will improve the quality of finished products. to & a device for heat treatment of meat products; in Fig. 2 - the same, side view in section; in Fig., 3 - the same, top view; in Fig. 4 - the same, cross section. The meat products contain chamber I, doors 2, frames 3 with the product, fans 4, coolers 5, dampers 6, spray heads 7, air conditioning 8 with dampers 9, smoke generator 10, fire extinguishing device II, smoke duct 12 with ventilator 13 and adjustable smoke damper 14, distribution air ducts 15 with sepla 16, distributor 17 with controllable slonkam 18 and a humidifier 19. suction duct 2O, duct 21 to remove the spent mixture with the outlet valve 22, ejector 23. program temperature controller 24 with sensor 25, control valve 26, humidity program controller 27 with humidity sensor 28 gate valves 9–22, program controller 29 cycles of operation, control of the gate valves 14. on “1 and off the valve” DZ ,, smoke generator Yu, fan 13 and gate 14. In the device there are also a circulation duct 31 and a control valve Shyunny

(air duct 32, commands the apparatus 33 for controlling the switching of the flaps 18 in a predetermined cycle, and in addition, fire protection, a sanitization system, and control devices for recording the temperature and humidity of media in square meters (not shown).

The device works as the next cut.

After loading the frames 3c with the product into chamber I, the doors 2 are closed and the automatic mode is activated. This includes software controls 24, 27, 29 command device 33 air conditioner 8, i fans 4 and automation automation scheme. The recirculation of air sucked from chamber 1 through the suction duct 2O to the stylizers 4 and under the influence of the fans 4 forced through coolers 5, the distributor 17, the ducts 15, the nozzles 16 and the chamber I.

In accordance with the 24, 27, installed on the program regulators, 29 graphic programs are installed and maintained thermal treatment modes with the required temperature, humidity and air velocity. At the same time, the signal from the sensor 25 of the temperature enters the controller 24 and the last, depending on the amount set on the program and received from the sensor, affects the valve 26. which, in accordance with the command, reduces or increases the flow of cold water e coolers 5.

The signal from the humidity sensor 28 enters the regulator 27 and the last, depending on the difference in the value specified on the program and received from. sensor acts on the valve 9 n 22 and increases or decreases the degree of their opening. In this part of the wet

Air is released to the atmosphere and replaced with dry air from the air conditioner. 8. Stable temperature and humidity parameters. Provided by the hema control of the air conditioner 8.

AT . if the humidity is low, the discharge of humid air is stopped and the humidifier 19 is turned on. The fan 4 of the circulation duct 31 provides pressure to obtain an average speed of air in the chamber. -. Lp increase or decrease the speed of air movement in accordance with the changing technological mode is a recirculation duct 32. Fine adjustment of the movement speed is achieved by controlling the damper 6. Coolers 5 serve to reduce the temperature of the circulating air and provide a hash of excess heat from the fans and the incoming smoke . The controller 29 provides for issuing commands in accordance with the program, reflecting the requirements of the technological process and Turns on or off the equipment of the air duct 32, the smoke generator Yu. The equipment of the ductwork 12, dampers 14 and 6.

The command 33, continuously in a predetermined cycle, controls the switching of the shutters 18 in the distributor 17, which allows the air flow to change direction to create disturbing air oscillations in the chamber 1 for better mixing. Sanitary equipment is processed on a manual basis. When the sanitation mode is turned on, the shutters 6 and 18 are installed in the open position, the fans 4 are turned on, the cleaning solution and steam enter the ejector 23. and from there, in the form of an aerosol mixture, enters the air ducts, where it is picked up by the circulating air flow, along the way they wash the internal surfaces and take the smoke sediments into the chamber. The inner surfaces of the chamber are treated with a detergent solution from a high pressure unit and the sediments are washed into the drain. In case of sunburn of resinous sediments in

the smoke duct 12 near the smoke generator Yu burns out a control tape in the fire extinguishing device 11 and releases a damper (not shown), which blocks the smoke duct 12 from the smoke generator Yu and simultaneously connects it to the atmosphere, gives a signal to turn off the smoke Yu. fan 13 of the fan 13, closing dampers 14 and steam supply to the chimney. At the same time, an audible signal is given to the operator. The use of the proposed device in the industry will allow all the stages of heat treatment in one chamber while maintaining optimal modes, which allows for the intrusion of the logging process, reduce possible product losses when before using the camera into the chamber and reduce labor costs and energy consumption for the production of smoked sausage products, Formula and 3 ore The device for heat treatment of meat products, containing a cameo n and O RU with distribution and suction ducts, characterized by so that, in order to regulate the air velocity in the chamber, it is equipped with a recirculation air duct connecting the distribution and suction ducts, and an adjustable damper and cooler are installed in the recirculation air duct. i Sources of information taken into account in the examination I, USTINOV M N.
