Cold chain distribution method based on underground working lunch

Abstract

The invention discloses a cold chain distribution method based on underground working lunch, which belongs to the technical field of mining food distribution. The method comprises the following steps:1) inspecting and accepting the hygiene qualification of raw food materials; 2) classifying and sterilizing the food materials; 3) taking a certain amount of food materials and heating; (4) carryingout aseptic cooling, then, carrying out uniform-weight bagging, and vacuumizing and sealing a bag body; 5) respectively putting the bag bodies into lunch boxes, and quickly freezing the lunch boxes ina centralized manner; 6) uniformly filling the meal boxes into an explosion-proof refrigeration box; 7) conveying the explosion-proof refrigeration box into the mine along with an equipment train; (8) heating the food, and immediately eating; and 9) sending the postprandial garbage out of the mine along with the equipment train. The method comprises the following steps of carrying out sterile pretreatment and cold chain distribution on food, the storage time of food can be greatly prolonged, meanwhile, good nutritional ingredients and taste of the food can be kept through high-temperature treatment, the design is reasonable, the practicability is high, a mature food processing system is provided for dining under the mine, the problem that the food is prone to deterioration and decay is solved, waste is avoided, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mine food distribution, in particular to a cold chain distribution method based on underground "shift lunch", which is used to improve the food cold storage technology in the high-temperature and high-humidity environment of coal mines. Background technique [0002] With the rapid development of coal mine production, the depth of mine mining and the continuous increase of geothermal heat, the problem of miners' meals needs to be improved urgently. Due to the special environment under the mine, it is not only inconvenient for miners to bring their own food, but also cannot be heated. Traditional thermal insulation distribution also has the problem of short storage time and easy corruption. At the same time, too much single delivery is easy to be corrupted, which will cause waste, and too little delivery cannot meet the dietary needs of miners.
