A food preservation technology for refrigerators

Abstract

A food fresh-keeping technology for refrigerators, which relates to the field of antibacterial and fresh-keeping technologies, and is characterized in that: a water-absorbing material is installed on the inner wall of the inner container of the refrigerator, and a bactericide and tourmaline are added or compounded in the water-absorbing material, A fan is installed in front of the water-absorbing material. The present invention can play the role of humidifying, moisturizing, antibacterial, deodorizing, and fresh-keeping on the fruits and vegetables in the refrigerating room of the refrigerator, and tourmaline releases negative ions and emits far-infrared rays, which can also remove pesticide residues and other substances in fruits and vegetables, further improving The quality of fruit and vegetable food.

Description

technical field [0001] The invention relates to the field of antibacterial and fresh-keeping technologies, in particular to a food fresh-keeping technology for refrigerators. Background technique [0002] With the development of society and the improvement of technology level, the requirements for refrigerators are not only to extend the shelf life of food, but also put forward higher requirements in terms of taste, texture and nutrition. [0003] At present, the design temperature of the refrigerating room in the refrigerator is usually around 1°C-10°C. Under this temperature condition, the water in the fruits and vegetables in the refrigerating room will evaporate to varying degrees, resulting in dehydration, discoloration, and dryness of the fruits and vegetables. Affect the freshness and taste of the food, and the water will form frost and solidify on the back wall of the inner container of the refrigerator. The water outlet on the inner wall flows away.
