Preparation method of antibacterial and deodorant material for refrigerator and freezer

Abstract

The invention discloses a preparation method of an antibacterial and deodorizing material for refrigerators and freezers. The specific surface area is 200m 3 / g-2000m 3 / g of porous material is used as a carrier, and the carrier is one or more of activated carbon, molecular sieve, and resin material. The carrier is chemically pretreated and dried and pulverized, and then impregnated with fine powder in soluble metal salts, vitamin B 12 , organic amines and additives, and finally molded and dried; soluble metal salts are one or more of silver salts, zinc salts, and nickel salts; the present invention uses soluble metal salts, vitamins, and organic amines Carriers are pretreated, and under the action of additives, the odorous gases in refrigerators and freezers are completely removed; the effective contact surface of active substances is improved, and the deodorizing effect is enhanced; the rapid reproduction of bacteria is inhibited, and the deodorization effect is slowed down. Reduce the spoilage speed of food and enhance the preservation effect; chemical adsorption is good, no release, no secondary pollution.

Description

technical field [0001] The invention relates to the technical field of odor purification in refrigerators, in particular to a preparation method of an antibacterial and deodorizing material for refrigerators and freezers. Background technique [0002] Refrigerators and freezers are widely used in the fields of household, catering and food processing. During use, there will be foul smell, which has an adverse impact on food safety and storage, and also gives people a poor sensory impression. The food, fruits and vegetables themselves emit, such as leeks, garlic, aquatic products, etc.; the other part is caused by the decomposition of bacteria that grow continuously on the food, which also accelerates the deterioration of food, such as the rot of vegetables and fruits, and the deterioration of cooked food; Typical odors of refrigerators and freezers include fishy odors such as dimethylamine and trimethylamine, rancid odors of sulfides such as mercaptans, hydrogen sulfide, and ...

Problems solved by technology

[0002] Refrigerators and freezers are widely used in the fields of household, catering and food processing. During use, there will be foul smell, which has an adverse impact on food safety and storage, and also gives people a poor sensory impression. The food, fruits and vegetables themselves emit, such as leeks, garlic, aquatic products, etc.; the other part is caused by the decomposition of bacteria that grow continuously on the food, which also accelerates the deterioration of food, such as the rot of vegetables and fruits, and the deterioration of cooked food; Typical odors of refrigerators and freezers include fishy odors such as dimethylamine and trimethylamine, rancid odors of sulfides such as mercaptans, hydrogen sulfide, and sulfides, odors of rotten eggs, and garlic odors; the above listed are only refrigerator odors Part of them, they all have the same characteristics, the threshold is extremely low, it is difficult to completely remove the odor

[0003] At present, the deodorization technology used in the industry cannot meet the use requirements in terms of removal efficiency and limit concentration. More importantly, it cannot continue to work under low temperature and high relative humidity conditions in the refrigerator, and is not suitable for refrigerators and freezers. Some R&D personnel try to apply ozone, plasma and other technologies to deodorize refrigerators, but due to the lack of safety requirements and processing capacity of refrigerators, practical applications cannot be carried out; based on the above reasons, it is necessary to improve the deodorization technology of existing technologies Improvements are made to make it suitable for antibacterial and deodorizing refrigerators and freezers
