Description

The invention relates to agriculture, in particular to milk coolers, and can be used in the primary processing of dairy farms. A milk cooler is known, which contains tubular elements in the form of three tubes that are concentrically mounted with an annular gap in each other tubes, allowing the coolant to pass through the inner tube and the outer annular annular cavity, and the milk flow through the inner annular annular cavity. operation, in particular due to the difficult access to the internal cavities of pipes for their cleaning. A known milk cooler contains two pressure plates, one of which has pipes for introducing milk and discharging cooling water, and the other for pipes for discharging milk and introducing cooling water, and st. between the plates, the cooling package, containing corrugated heat transfer plates with sealing gaskets, located between the two holes in each plate, forming two channels in the package — for water and cooling water — are coupled with corresponding pressure connections. plates 2. . However, the known cooler does not provide a sufficiently high quality of milk. The purpose of the invention is to improve the quality of milk. This goal is achieved by the fact that a milk cooler containing two pressure plates, one of which has branch pipes for introducing milk and discharging cooling water, and another - patches for discharging milk and introducing cooling water, and a cooling bag stretched between said plates containing corrugated heat transfer plates with gaskets, located between two holes in each plate, forming two channels in the package - for feeding milk and cooling water, coupled with the corresponding pipes on clamping plates, provided with filtering elements, which are located in the channels perpendicular to the longitudinal axis of the package. Moreover, the filtering elements are located on the side of the milk inlet pipe and are made in the form of grids which are fixed on the plates. In order to prevent the filtrate from entering the milk line when washing the cooler, the milk inlet pipe is equipped with a stop valve. Figure 1 shows the proposed milk cooler; Fig. 2 shows a corrugated plate with a grid fixed thereto; a section; 3 frame plate with grid; in fig. 4, the same cross section, the Milk cooler has pressure plates 1 and 2, between which a cooling pack is installed, having corrugated plates 3. The pressure plate .1 has a branch pipe 4 for introducing milk and a branch pipe 5 to drain the coolant. The pressure plate 2 has a nozzle 6 for draining the cooled microfuge and a nozzle 7 for introducing coolant. The corrugated plates 3 along the edges are sealed with elastic pads 8. In the plate pack, from the milk inlet side, filter elements 9 are installed, which are made in the form of a corrugated plate 10, on which the milk screen is fixed on the milk supply side; In another embodiment, the plate can be made in the form of a frame 12, on which a fixed filtering mesh 13. To prevent the filtrate from entering the milk conduit during cleaning of the system, at the end of the operation in the α-pipe 4 there is a stop valve containing aschy locking member 14 with the handle 15. Between the valve and the pressure plate 1 in the nozzle 4 is made a threaded hole 16, kotor.oe closed stopper 17 has a seal 18. The milk cooler operates as follows. Nozzle 4 is connected to the milking system of the milking machine, and nozzle 7 is connected to cold water mains. The system of gaskets after assembling and compressing the corrugated plates in the package forms two insulators for the milk and coolant channels. Last moves to

the device is counterflowed to the milk, which through the pipe 4 enters the bag, the passage through the filtering grids located on the plates 10 or 12 is cleaned of mechanical impurities and cooled, the passage through the bag. The cooled and purified milk through the nozzle 6 leaves the device and is collected in a tank.

At the end of the milking, the device is rinsed. By turning the handle 15, the valve is closed by the locking element I4 and the plug 17 is opened to allow the discharge of the filtrate. A coolant hose is connected to the outlet nozzle 6, which is 65344. four

It is removed from the nozzle 5 and reverse pressure is applied to the milk duct under pressure. Through the outlet 16, the filtrate located on the filter screen is flushed and drained to the sewer. After draining the contaminated liquid, a circulation wash is performed: the whole system is milk .10 wire. This is open

valve and plug 17 closes. Washing is carried out in the usual manner.

The use of the proposed milk cooler allows milk filtration to be carried out 15 during its cooling, which improves the quality of the milk.
