High-gradient magnetic field oxygen separation adsorption fresh-keeping device

Abstract

The invention discloses a high-gradient magnetic field oxygen separation and adsorption preserving device. An air inlet fixing net is arranged at an air inlet at the upper end of a shell, and an exhaust pipe is arranged on an air outlet at the lower end of the shell, wherein an axial flow fan is arranged in the exhaust pipe; an air outlet fixing net is arranged between the exhaust pipe and the lower end of the shell; at least two permanent magnets are arranged on each side surface of the shell; the inner surfaces of the permanent magnets on the same side surface have the same polarity; the inner surfaces of the permanent magnets on two opposite side surfaces have different polarities; the inner surfaces of the permanent magnets on two adjacent side surfaces have the same polarity or different polarities; a baffle is arranged between a permanent magnet and an adjacent permanent magnet which are arranged on the same side surface; the baffles on the same layer are sticked together; and the shell is filled with magnetic-conductive stainless steel fur. The shell is of a reverse even prism frustum cylindrical structure, and the taper angle of the shell is between 80 degrees and 150 degrees. The high-gradient magnetic field oxygen separation and adsorption preserving device has the advantages of reasonable design, simple structure, high oxygen removal efficiency, dehumidifying function and the like, and can be popularized to refrigerating equipment.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and preservation equipment for vegetables and fruits, and in particular relates to equipment or devices for providing low-oxygen and humid air to refrigeration spaces. Background technique [0002] Refrigeration equipment is used to store food, vegetables, and fruits at lower temperatures to extend their quality and freshness. During the storage process, food, vegetables, and fruits often deteriorate and shrink. As reported in related data, the main cause of food deterioration is due to microbial action, oxidation and respiration of stored food (vegetables, fruits) in the refrigerated space; food shrinkage is caused by too low humidity in the refrigerated space. Obviously, the above factors are all related to the air environment of the refrigerated space. Studies have shown that reducing the oxygen content in the air in the refrigerated space, killing the planktonic microorganisms in the ai...

Problems solved by technology

The main disadvantages of this fresh-keeping device are: one, the negative ion concentration produced by corona discharge is very low, and the bactericidal effect is poor; , ozone will pass through the permanent magnet and the deoxidizing powder between the permanent magnets without any hindrance to form a deoxidation zone, and the ozone passing through the fresh-keeping device will be decomposed into oxygen in the refrigerator space, so its deoxygenation effect is not good; third, use iron powder The deoxidizing powder prepared with water removes the oxygen passing through the airflow, which has the problems of low oxygen removal efficiency and unsustainable oxidation reaction

This is mainly due to the spontaneous oxidation reaction on the surface of the iron powder for the deoxidation of the iron powder, and the premise of maintaining its spontaneous oxidation reaction is that there must always be a supply of water, and there is no continuous supply of water in this patent, so the surface of the iron powder spontaneously The oxidation reaction cannot be sustained, resulting in poor deoxidation effect
