(54) MILK TANK-COOLER

(57) The invention relates to the dairy industry and can be used on farms for the primary processing of milk. The purpose of the invention is to reduce energy consumption and

Reduced metal consumption The cooler tank contains a housing with a milk bath with a cooling jacket, a mechanical stirrer, a tray and a coolant flow former, as well as manifolds for supplying and discharging refrigerant. The supply manifold is placed in the coolant tray , and the collector for removal - in the upper part of the cooling jacket. The sweater is made in the form of two plates, repeating the shape of the bath and draped in the lower part to form a longitudinal slit. overhnosti potokoformirova- bodies protrusions are staggered, and the collector are provided with openings whose diameter increases along the coolant sealed about 2 f-ly, about 3 yl

§

WITH

The invention relates to milk collections with refrigeration units, namely, equipment for collecting, cooling and storing milk on livestock farms, can also be used in dairy plants and in the food industry.

The purpose of the invention is to reduce energy consumption and reduce metal consumption

Modern cooling systems of a similar type have a continuous flow cooling system in which the coldest layers of milk are through. the bath wall transfers heat to the coolant having the highest temperature in the circulation cycle through the cooling system. This significantly reduces the heat transfer rate and increases the duration of the cooling process.

Intensification of the cooling process is achieved by creating a backflow circulating system due to absorption of the coolant coming from the refrigerating machine and having the lowest temperature, countercurrent to the milk flowing along the inside of the bath. At the same time, in the lower part of the tank, the maximum

possible temperature difference between milk and coolant, therefore, the heat transfer process is intensified and cooling time is reduced.

FIG. 1 shows a cooler tank, a longitudinal section; on figo- same, cross section} on fig. 03 - node I on fig01 o

The tank includes a shock-absorbing housing 1 in which a milk bath 2 is located, having a milk distributor 3 In the upper part of the tank, around the perimeter of the bath 2, there is a suction manifold 4 for discharging coolant, which has holes 5 along its length decreasing in the direction to the suction A nozzle with dimensions of diameters0. Inside the milk bath 2, there is an agitator 6, and the plates 7 are located on the outer side of the bath 2 inside the body I of the tank and form a flow former 9 that repeats the shape of the baths. The windings are located with a gap to the walls of the bath to form a cooling shirt. Thanks to the protrusions 8, which are perfect on the inner side of the plate 7, displaced relative to each other, te0 in a checkerboard pattern, a cavity 9 dl is formed cold storage passage with variable length and not cross section

The plates 7 are attached in the upper part to the flanging of the milk bath 2 and are sealed with gaskets 10 and 11 and in the lower part of the stand are elements

12 with the formation of a width-adjustable gap for sucking water with a certain capacity depending on the given capacity 0 The tank is equipped with a pallet

13 liters of coolant connected to the evaporator 140 The mixer is rotated by an electric motor and the intake manifold 4 is connected to a self-priming pump 15 °. A collector 16 for supplying the coolant is placed in the pan 130

The tank cooler works as follows

A pump 15 pumps water, heated in cavity 9, into the evaporator 14, where it is cooled and enters the sump 13, from where it is sucked through the gap between the plates 7 into the cavity 9,

passage through branched channels between the wall of the milk bath 2 and the protrusions 8 into the collector 4 and then re-enters the evaporator 140 The branching of the coolant flows between the projections 8 and the bottom of the bath 2 contributes to their turbulization even at speeds of 0.1-0.25 m / c, and the rise of the coolant to meet the flowing milk flow is intensive heat exchange, since during such movement throughout the entire heat exchange surface there is a temperature difference between the heat exchanging media anywhere in the surface of the milk bath 2 "Pass vanie coolant reservoir to the entire length of the channel helps to reduce the resistance for the coolant, and hence reducing energy consumption

Claims (1)

The proposed technical solution, by performing a flow-forming of two plates installed with a gap to carry out the circulation supply of coolant with simultaneous turbulization, reduces the energy consumption of the cooling process and laboriousness of its manufacture due to the exclusion of welded works during the manufacture of the tank, and as a result, reduce its allometry about the formula of the invention / 1o Milk tank-cooler, comprising a housing, a milk bath with a mechanical stirrer and a cooling jacket with a flow former disposed thereon, a coolant tray and collectors, respectively, for supplying and discharging coolant, in order to reduce electricity consumption and reduce metal consumption , the flow former is made in the form of two plates, repeating the shape of the bath and stretched in the lower part with the formation of a longitudinal slit, the supply manifold is placed in the coolant pan, and the call Ktorov for removing located at the top of the cooling rubagakIo 2 of the reservoir-cooler in which the protrusions are arranged in a staggered order on the inner surface of the plates of the flow former. 3.
