Description

The utility model relates to agriculture and can be used for thermization of milk in order to reduce bactericidal activity with its subsequent cooling.

An invention is known (a patent for a utility model of the Russian Federation No. 179014 dated 04/25/2018, I.V. Zefirov, V.A. Sukhlyaev, K.V. Tyurmakov). A device for cooling milk on farms, containing a recuperative heat exchanger for cooling fresh milk with water from an artesian well supplied by a water supply pump, a plate heat exchanger for further reducing the temperature of milk with ice water obtained in the evaporator of the refrigeration unit, with the possibility of further milk entering the cooling tank, while the device is designed in such a way that artesian water, heated by the warmth of milk in a recuperative heat exchanger, has the ability to cool the refrigerant in the condenser of the refrigeration unit, taking away the heat taken away when cooling milk with ice water obtained in the evaporator of the refrigeration unit, and the heat of the compressor of the refrigeration unit operating in the mode heat pump, due to which the water is heated and supplied to the thermally insulated container of the farm yard for use for technological needs.

The disadvantages of this installation are the lack of thermization of milk and high material consumption.

A device is known (a patent for a utility model of the Russian Federation No. 187616 was published on March 13, 2019, by S.V. Gaididey, I.V. to the claimed utility model. Milk thermization device with subsequent cooling during milking, consisting of a compression refrigeration unit, including a compressor, a condenser, an evaporator, a throttle, a recuperative milk cooling heat exchanger, a milk pipeline and a cooling tank, while the milk cooling heat exchanger is configured to cool milk with ice water obtained in the refrigeration evaporator.

The disadvantages of this device is the lack of control over the temperature of thermization of milk and the high inertia of heating.

The technical result of the utility model is to control and maintain the thermization temperature of milk, obtained due to the heat released in the condenser of the compression refrigeration unit, and to accelerate the heating of milk to the thermization temperature at the beginning of the process.

The technical result is achieved by the fact that a temperature sensor, an electronic control unit and an electric heater are used to control and maintain the thermization temperature and accelerate the heating of milk.

The essence of the utility model lies in the fact that the device for thermization of milk with subsequent cooling during milking consists of a compression refrigeration unit, including a compressor, condenser, evaporator, throttle; milk pipeline; a milk thermization heat exchanger with the possibility of milk entering it from a milk pipeline and a milk cooling heat exchanger, and made with the possibility of chilled milk entering the cooling tank, unlike the prototype, a temperature sensor is installed at the outlet of the milk thermization heat exchanger, configured to receive information about the temperature of the milk to the electronic unit, which has the ability to transmit a signal to the electric heater.

The figure shows a diagram of a device for thermization of milk with subsequent cooling during milking.

The device consists of a compression refrigeration unit, including a compressor 1, a condenser 2, an evaporator 3, a throttle 4, a milk thermization heat exchanger 5 with the possibility of milk entering it from a milk pipeline 7 and a milk cooling heat exchanger 6, as well as a temperature sensor 9 installed at the outlet of the heat exchanger thermization of milk and made with the possibility of receiving information about the temperature of the milk to the electronic unit 10, which has the ability to transmit a signal to the electric heater 11. The device is made with the possibility of receiving cooled milk in the tank-cooler 8.

The proposed device works as follows. Milk from the milk line 7 enters the heat exchanger 5, where it undergoes thermization with water heated in the condenser 2 of the refrigeration unit. Then the milk enters the heat exchanger 6, where it is cooled with ice water obtained in the evaporator 3 of the refrigeration unit. The refrigerant in the refrigeration unit is pumped by the compressor 1 and dosed by the throttle 4. Then the cooled milk enters the cooler tank 8. The electronic control unit 10 receives information about the temperature of the milk at the outlet of the heat exchanger 5 from the temperature sensor 9, and, in the case when the milk temperature is lower than thermization temperature, the electric heater 11 is switched on by the signal of the electronic control unit 10. When the required thermization temperature is reached, the electric heater is switched off by the signal of the electronic control unit.
