Controlled atmosphere fresh-keeping logistics transportation method for foods

Abstract

The invention relates to the field of controlled atmosphere fresh-keeping logistics transportation and in particular relates to a controlled atmosphere fresh-keeping logistics transportation method for foods. The method comprises the following steps: replacing air in a controlled atmosphere logistics box used for containing foods with preservation gases mixed according to the needed ratio of the foods by virtue of distribution equipment before logistics transportation according to the types and physiological properties of the foods; and independently transporting the controlled atmosphere logistics box in which the foods are filled and the preservation gases are introduced. According to the method, multiple fresh meat, cooked products, melons and fruits and vegetables can be simultaneously subjected to controlled atmosphere fresh-keeping logistics transportation in a refrigerated transport compartment, and the problem that multiple foods cannot be subjected to controlled atmosphere fresh-keeping mixed transportation in the logistics industry is solved. According to the method, the logistics boxes of various different sizes are subjected to controlled atmosphere fresh-keeping logistics transportation of the foods, and the preservation gases can be mixed in the controlled atmosphere logistics boxes of various different sizes by virtue of the distribution equipment. The method is simple and convenient, and the controlled atmosphere logistics boxes do not need to be regulated in the transportation process. The energy consumption in the logistics transportation process is reduced, and circulation of perishable foods is improved.

Description

technical field [0001] The invention relates to the field of logistics transportation, in particular to a logistics transportation method of modified atmosphere preservation for food. Background technique [0002] Controlled atmosphere fresh-keeping control technology is to adjust the food storage environment temperature, relative humidity and the ratio of various gases such as oxygen, carbon dioxide, nitrogen, etc., so as to achieve the purpose of prolonging the fresh-keeping period and improving food quality. However, the logistics and transportation of food after modified atmosphere preservation has become a difficult problem in my country and the world, and it is also a difficult problem for my country's agriculture, food processing enterprises, and logistics enterprises. At present, developed countries such as Europe and the United States have realized fresh-keeping transportation of air-conditioned containers in ocean-going shipping. Due to the cost of use and purchase...
