Mar 01, 2024|
View:100Cold storage logistics
Refrigerated container refers to a special container that has good heat insulation and can maintain a certain low temperature requirement, and is suitable for the transportation and storage of all kinds of perishable food.
Refrigerated containers are constructed of galvanized steel, with inner walls, bottom plates, roof plates and doors made of aluminum, stainless steel or polyester. At present, the international container size and performance have been standardized. The temperature range of refrigerated containers is -30 ° C to 12 ° C, and the more general range is -30 ~ 20 ° C.
The basic types of reefer containers include insulation containers, external reefer containers, internal reefer containers, liquid nitrogen and dry ice reefer containers, freezer plate reefer containers, etc.
Cold chain logistics
Cold Chain Logistics generally refers to the refrigerated frozen food in the production, storage, transportation, sales, to the pre-consumption of each link is always in the specified low temperature environment, in order to ensure food quality, reduce food loss a system engineering.
Generally applicable to some primary agricultural products, processed food, such as vegetables, fruits, meat, poultry, eggs, aquatic products, flower products, frozen food, poultry, meat, aquatic products and other packaged cooked food, ice cream and dairy products, chocolate, fast food raw materials, etc.
In addition, there are some special commodities, such as pharmaceuticals, fresh milk and dairy products, which have high transportation requirements and require very accurate temperature control.
Constant temperature logistics
The so-called constant temperature refers to the constant temperature, not necessarily low temperature, transport temperature 20-40℃ of goods are also many, such as some food delivery car is to constant temperature.
In fact, both refrigerated logistics and constant temperature logistics can be classified into the cold chain logistics category. Cold chain logistics freight is generally about 150 yuan per square meter, which is generally charged according to the weight of storage per square meter and the number of kilometers of transportation. And different seasons, different routes its transport price is different, but also subject to the actual situation.
