Quick-freeze storage with magnetic field device and operation method of quick-freeze storage with magnetic field device

Abstract

The invention relates to a quick-freeze storage with a magnetic field device and an operation method of the quick-freeze storage with the magnetic field device. The quick-freeze storage with the magnetic field device is simple in structure, convenient to use, good in quick-freeze effect and capable of effectively reducing energy consumption, and comprises a magnetic field generation device. The magnetic field generation device is disposed in the blowing type quick-freeze storage and connected with a control circuit outside the blowing type quick-freeze storage and consists of Helmholtz coils in pairs, and the Helmholtz coils are connected with the control circuit which controls the Helmholtz coils under direct current. A magnetic field generated by the Helmholtz coils is distributed in a whole freezing space of the blowing type quick-freeze storage, and the magnetic field intensity of the magnetic field generation device is 0-1000GS. During quick freeze of food, temperature of the food in the quick-freeze storage is monitored in real time, the magnetic field is not added in an initial temperature-fall period but added when the temperature falls to a set temperature, and after a phase change process is completed, the temperature continues to fall to the set temperature, the control circuit is disconnected, the magnetic field is not added any more, and freezing continues.

Description

technical field [0001] The invention relates to a quick-freezing store, in particular to a quick-freezing store with a magnetic field device and an operating method thereof. Background technique [0002] The quick-freezing warehouse is a common way of food preservation and storage. In order to meet the requirements of quick-freezing, the existing quick-freezing warehouse adopts methods such as increasing the air flow in the quick-freezing warehouse, setting up more evaporators, using different temperature ranges for quick-freezing, and improving the structure of the freezing tunnel. Improve the efficiency of quick-freezing, but it often needs to consume a lot of power to achieve quick-freezing, and because the efficiency is not high, the process of quick-freezing is still long, which will further increase energy loss, and have a certain impact on food preservation and quality. Thawing Food quality sometimes decreases afterwards. Contents of the invention [0003] The purp...
