Abstract

Use: in agriculture. CyuiHOCTb of the invention: a device for cooling milk contains a refrigeration unit with an evaporator having an inlet and an outlet for water, as well as a milk cooler. The milk cooler has two connected in series, along the line of the milk section, the first of which is connected to the fresh milk pipeline, and the second to the storage tank for chilled milk. On the water line, the inlet and outlet of the second section of the cooler are communicated respectively with the outlet and inlet nozzles for the evaporator water. The device is equipped with a cooler-heat exchanger with a sprinkler and a heat-insulated reservoir for chilled water. The first section of the milk cooler through its water inlet is connected by pipeline to the water tank, and the outlet to the reservoir for the heated water. The second section of the milk cooler through its water inlet is in communication with the chilled water tank, and with the outlet, with the heat exchanger cooler sprayer and with the cooled reservoir. 1 il.

Description

The invention relates to agriculture and can be used to cool milk.

Milk cooling plants are known to include a heat exchanger, a chladonic carrier cooler in communication with the atmosphere, circulation pumps and piping systems, as well as milk tanks, a milk supply pump, a heat exchanger with a fan, and the like.

The disadvantage of opposing devices is high power consumption and the associated lack of application efficiency.

The aim of the invention is to increase efficiency and reduce energy consumption when cooling milk on livestock farms.

The goal is achieved by the fact that the device for cooling milk on farms contains a refrigeration unit with an evaporator having water inlet and outlet pipes interconnected and equipped with regulating shut-off valves, milk cooler with two sections connected in series along the milk line. which are connected to the fresh milk pipeline, and the second to the storage tank for chilled milk. On the water line, the inlet and outlet of the second section are communicated respectively with the outlet and inlet pipes for the evaporator water. The device also includes a water tank with a float, a regulator with a cold water supply pipeline and heat insulated

reservoir for warm water, communicated with automatic water dispensers.

The device is equipped with a cooler-heat exchanger with a sprinkler and a heat-insulated reservoir for chilled water.

The first section of the milk cooler, through the water inlet line, communicates with the water tank, and its output with the heat insulated tank for the heated water. The second section of the milk cooler in the water line is connected with its inlet to the chilled water tank, and to the outlet with the cooler spray heat exchanger and to the chilled water reservoir. The chilled water reservoir is piped to the evaporator water inlet.

The essential differences of the proposed device are that it is equipped with a refrigeration unit, a drinking water tank and an annular water supply pump communicated with a heat exchanger, which is made in the form of a heat-insulated body with a tray in which a float valve and a spray nozzle are mounted.

The drawing shows a schematic diagram of the proposed device.

The device can be used in summer and in winter mode. In summer mode, the cold produced by the refrigeration unit is mainly used.

In winter, water from the tank 15 is pumped to the first section of the milk cooler and heated enters the heat exchanger sprinkler 9 and is cooled by the flow of external atmospheric air drawn through the plates of the heat exchanger 9 and cooled through the holes in the sump accumulates in the insulated cooled water tank 7. From the tank 7 through the grid 17, the cold water is pumped through the pump through the second section of the milk cooler from which it returns to the heat exchanger unit 9 for cooling. and outside air. The water from the first section of the cooler, as more heated (in the main mode of operation), is sent to the heat-insulated container A, in which, if necessary, it is heated to the optimum temperature of water due to the built-in heating element and enters the auto drinkers, as well as to feed the water ring vacuum pump 16. water in the system is compensated by automatically feeding the system from the external water supply through valves 12. With a lack of external cold, the water from

the cold battery through the filter 17 passes into the evaporator of the operating refrigerating machine 5 and then with the pump 6 is sent both to the milk cooler and to the tank

for storing milk 1. Fresh milk from tank 2 by milk pump 3 is run through both sections of the cooler and is stored in storage in a tank (tank) 1 from which milk is taken for shipment to the customer.

The heat exchanger unit 9 is protected from icing by thermal insulation, inclined air intakes, and the ice formed by the cooling R 9 is thawed out by circulating water having positive

temperature due to the heat of milk given to the water in sections P (if necessary) and in section 1 of the milk cooler. A control system (valve system) automates the process and separates the lines.

cooling into two independent ones or allows working in a combined mode, which is determined by the specific conditions of operation of the installation, for example, a break in the water supply from the line

external plumbing, etc.
