Fruit and vegetable storage and transportation microenvironment multi-field coupling anti-corrosion and fresh-keeping equipment

Abstract

The invention relates to fruit and vegetable storage and transportation micro-environment multi-field coupling anti-corrosion and fresh-keeping equipment. The equipment comprises a preservative dispensing system, a preservative low-magnetic-flux-density static magnetic field synergistic pre-cooling treatment system, an ultrasonic pressurization first-stage atomization system, a gas-liquid two-phase second-stage atomization system, a high-voltage static electric field nanometer third-stage atomization system, a high-pressure pure nitrogen storage and control system, a pure nitrogen pressurization system, a nitrogen membrane separation preparation system and an air multi-stage purification system. The equipment is scientific and reasonable in design and efficient in use, and organically combines a preservative low-magnetic-flux-density static magnetic field synergistic pre-cooling treatment technology, an ultrasonic high-pressure spraying and static-pressure ionization combined three-stage atomization technology and an air multi-stage purification and micro-membrane nitrogen generation technology; the nano-scale atomization antibacterial effect of more than ten plant sources such as chlorine dioxide, peracetic acid, hydrogen peroxide, plant essential oil and organic acid and green chemical bacteriostatic agents can be achieved, novel, efficient and safe use of food-grade bacteriostatic agents is improved, and the product is suitable for different types of fruits and vegetables and is alternately used to avoid drug resistance of pathogenic bacteria; and the equipment can be industrially applied to fruit and vegetable storage, transportation and sale preservation.

Description

technical field [0001] The invention belongs to the field of storage and preservation of agricultural products, and relates to fruit and vegetable storage and transportation technology, in particular to multi-field coupled anti-corrosion and fresh-keeping equipment for fruit and vegetable storage and transportation micro-environment. Background technique [0002] Fruit and vegetable storage and preservation is a system engineering technology. Temperature, humidity, gas and anti-corrosion are the four major elements of modern fruit and vegetable preservation. Anti-corrosion is the key to fruit and vegetable preservation. Pathogenic bacteria are the main cause of fruit and vegetable rot and food-borne diseases, and drug resistance is increasing year by year, which increases the types, dosage and processing time of chemicals year by year, so that in order to deal with dozens of common pathogenic bacteria, we have to Hundreds of pesticides have been developed. [0003] However,...
