Sponge iron modified atmosphere fresh keeping device for refrigeration space

Abstract

The invention relates to a sponge iron modified atmosphere fresh keeping device for a refrigeration space. An upper cover is arranged at the upper end of a casing, a nanometer TiO2 foam nickel net is coated on the upper surface of an air inlet of the left side wall of the casing, an axial flow fan is arranged on an air outlet of the right side wall, a water inlet valve communicated with the inside of the casing is arranged under the left side of the casing, a water outlet valve communicated with the inside of the casing is arranged under the right side, an ultraviolet light emitting diode is arranged on the inner side wall of the casing, water is contained at the bottom inside the casing, an upper permanent magnet is arranged on the upper cover, a lower permanent magnet is arranged at the bottom of the casing, N poles and S poles of the upper permanent magnet and the lower permanent magnet are in opposite arrangement, the upper end of a left non-magnetic-conducting stainless steel net is arranged on the left end surface of the upper permanent magnet arranged on the upper cover, the lower end of the left non-magnetic-conducting stainless steel net is arranged on the left end surface of the lower permanent magnet arranged on the inner bottom plate of the casing, the upper end of the right non-magnetic-conducting stainless steel net is arranged on the right end surface of the upper permanent magnet arranged on the upper cover, the lower end of the right non-magnetic-conducting stainless steel net is arranged on the right end surface of the lower permanent magnet arranged on the inner bottom plate of the casing, and sponge iron particles are filled in a space formed by the two non-magnetic-conducting stainless steel nets and the two permanent magnets.

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
