Abstract

FIELD: agriculture. The aim of the invention is to increase the operational reliability of the tank. Milk tank contains a bath 1, installed in the housing 2 with a gap S. Thermal insulation layer 3 is placed in the gap between the walls of the casing and the bath. The bottom of the casing and the bath are made semi-cylindrical. In the bath, the agitator 4 with Drive 5 is installed. The tank body is mounted on legs 6. The displacement of the bottom of the bath relative to the bottom of the body is 0.6-0.9 times the gap G. The volume of the semi-cylindrical part of the bath is at least 60% of the maximum volume (capacity) .baths Such an arrangement of the bath in the housing allows the milk temperature to be kept constant while partially filling the bath. 1 il.

I The invention relates to agriculture, in particular to devices; FOR Storage of chilled milk on: livestock farms. I The purpose of the invention is to increase the ex-: operational reliability by maintaining a constant milk temperature with partial filling of the bath. . The drawing shows a tank

river section.

: The milk tank contains a horizontally positioned bath 1, covered by the front with the formation of a gap i by the body 2, and a thermal insulation layer 3 placed in the gap 3. The bottom of the bath and the body are semi-cylindrical. The tank is equipped with an I-4 stirrer 4. with a drive 5, and the hull is supported by I with the legs 6. Vanya 1 is made equal-I-distant (equidistant by the size of the gap §) to hull 2; and its days I are shifted upward relative to the bottom of the first case I by the value of NJ constituting 0.6-0.9 of the gap 5. In this case, the gap is filled with thermal insulation I, the thickness of which varies from 1 to 1 In this case, parts of the tank to the size of S + N in the first part, and the thermal insulation itself is adjacent to the inner and outer surfaces of the hull and bath, respectively. The volume of the semi-cylindrical part of the bath is 60-100% of the maximum volume (capacity) of the bath. .. /:.-.- /; .

The milk tank is operated as follows.

In the process of reaching the milk, cooled to a temperature of 4-7 ° C, is fed into the tank for storage, which is covered with lids. At the end of the tank filler, the agitator is turned on. four,;. mixing the collected milk. The heat transfer between the surrounding air and milk is influenced by the heat transfer from the wall of the bath to the milk, which dramatically increases with the mixing of the latter. The process of mixing does not bypass in order to avoid settling of fat

Therefore, it is necessary to use a cyclic mixing mode (1-2 minutes after each hour of storage) that satisfies the conditions of milk storage. Given the geometric dimensions of the bath and the volume of its cylindrical part, it can be calculated for the total filling volume, thermal insulation thicknesses. The calculated thickness corresponds to the gap S in the upper part of the tank, according to which the bath is installed in the hull. Then, without disturbing the structural design of the casing, the bath is shifted upward by 0.6-0.9 times the size of the gap S, and the lower volume of the cylindrical part of the bath corresponds to a smaller value of the volume. The gap is filled with thermally insulating material (foaming polyurethane foam), which flies to the inner and outer surfaces of the casing and bath. Performing the thermal insulation of the temporal thickness optimizes the thermal properties of the tank, which remain constant for any filling volume.
