A separate independent control device for humidity inside a cold chain freezer

Abstract

The invention relates to the technical field of freezer humidity control, and discloses a separate independent control device for the internal humidity of a freezer with a refrigerated chain. There is a slide rail, the surface of the slide rail is slidably connected with a slide plate, the inside of the placement plate is movably connected with a push plate at the bottom of the slide plate, the bottom of the push plate is movably connected with a spring plate, and the inside of the placement plate is located at the back of the spring plate. There are vent holes. After the spring plate exerts a certain force on the surface of the temperature difference bag, the gas balance inside the temperature difference bag is destroyed under pressure, and the heating bag is squeezed to release heat, and then the heat is blown out by the gas, and flows into the mixing tube through the exhaust plate , because the gas flowing through the air outlet is cold gas, the two will mix in the mixing tube and then flow out to the surface of the food, that is, reduce the temperature difference between the food and the airflow inside the shell, thus reducing the temperature difference on the food surface The effect produced by water droplets.

Description

technical field [0001] The invention relates to the technical field of humidity control of freezers, in particular to a separate independent control device for humidity inside a freezer with a refrigerated chain. Background technique [0002] The freezer is a device that can create cold air. The food put in the freezer can increase its storage time and reduce the growth of bacteria. With the development of science and technology and the advancement of industrial technology, various types of freezers have been developed. Types, such as: double door freezer, single door freezer, miniature freezer and so on. [0003] After understanding the working process of the freezer, it is found that water droplets often appear on the inner wall, and the appearance of water droplets will increase the humidity inside the freezer. When the humidity inside the freezer becomes high, it will improve the growth conditions for the microorganisms in the food, thereby accelerating the growth of foo...

[0003] After understanding the working process of the freezer, it is found that water droplets often appear on the inner wall, and the appearance of water droplets will increase the humidity inside the freezer. When the humidity inside the freezer becomes high, it will improve the growth conditions for the microorganisms in the food, thereby accelerating the growth of food. deterioration, and high humidity will retain the odor inside the freezer and affect the normal operation of the freezer. Therefore, a separate independent control device for the internal humidity of the freezer with a cold chain came into being.
