Method for milk cold storage by milk storage quick-cooling machine

Abstract

The invention relates to a method for a milk cold storage by a milk storage quick-cooling machine. The method comprises starting a refrigeration structure of the milk storage quick-cooling machine before or after milk is added into the milk storage quick-cooling machine, at the same time, absorbing cold quantity by a cold storage structure, and storing a part of cold quantity generated by the refrigeration structure in the cold storage structure; after milk is added into the milk storage quick-cooling machine, cooling milk by utilizing contact heat exchange between milk and the milk storage quick-cooling machine inner wall, so as to cool milk to a temperature suitable for milk storage; and when the refrigeration structure stops working, releasing cold quantity by the cold storage structure, so as to maintain the milk temperature at a temperature scope suitable for milk storage at a period. The method helps to solve the problem that milk temperature rises during power-off transportation, and enables milk to be stored at a low temperature for a long time after power is off.

Description

technical field [0001] The invention relates to the field of milk refrigeration, in particular to a method for cold storage of milk by a milk storage quick cooler. Background technique [0002] In the traditional liquid milk production process, the processed milk needs to be cold-stored to inhibit the reproduction of microorganisms, extend the antibacterial period of the milk itself, and reduce deterioration. The traditional cold storage equipment is usually a tank with a cooler system . However, this equipment has simple structure, poor cooling effect and slow cooling speed. [0003] Existing milk is stored and kept fresh in herdsmen's homes, usually using refrigerators to keep fresh, and the temperature will be kept below 6°C. However, using a freezer to keep fresh at low temperature will have the characteristics of slow cooling speed and difficulty in keeping fresh milk when transferring it. Put the milk in the freezer, if the milk is still, it will take 10 hours or lo...

AI Technical Summary

Problems solved by technology

However, the rapid cold storage device in the above-mentioned patent is not easy to clean the interior, and there is no cold storage structure and heat preservation structure. After the cooler stops cooling, the temperature of the internal milk can easily rise to the ambient temperature.

[0005] Conventional methods cannot solve the problem of fast cooling and inconvenient transfer. There is no power supply during the milk transportation, so the internal milk cannot be refrigerated from time to time. After the power is cut off, the milk cannot be kept fresh for a long time, and the milk is easy to deteriorate.
