Cold chain logistics cold storage is cold chain enterprise food frozen processing, low temperature storage place, food cold chain includes: frozen storage, fresh sales, frozen processing, refrigerated transport and other aspects. Frozen processing and low temperature storage, meat and poultry, aquatic fish and eggs in the frozen processing between the cooling, frozen and stored in the low temperature storage.
In addition, the pre-cooling of fruits and vegetables and a variety of quick-frozen food, dairy products are also low-temperature processing between the processing. Large cold chain transport center cargo is very much, a variety of food preservation temperature requirements are not the same.
Cold chain logistics cold storage construction should be divided into different categories of the corresponding temperature, generally divided into high temperature, medium temperature, low temperature three different temperatures.
High temperature generally in 0 ℃ ~ 8 ℃, for fresh fruits and vegetables,
Low temperature generally in -18 ℃ ~ 23 ℃ below, and some are up to -35 ℃ below, for aquatic products, poultry meat frozen frozen.
Cold chain logistics cold storage construction: the use of cooling facilities to create appropriate humidity and low temperature conditions of the warehouse. Also known as cold storage. Is the processing, storage of agricultural and livestock products of the place. Can get rid of the impact of climate, to extend the shelf life of agricultural and livestock products to adjust the market supply. For the ongoing development of the construction of the cold storage, cold and cold refrigeration with the most practical needs of the customer, the theory combined with practical and years of experience, to provide customers with a reasonable cooling program. For customers to save investment, and produce good economic benefits.
Cold chain logistics cold storage construction steps:
First, the location: logistics warehousing cold storage generally based on the development of their own enterprises in the land price cheaper traffic relatively convenient location, cold storage around should avoid heavy pollution sources, floor should be flat, hard and dry, the surface is generally concrete, Should open the wind direction, open the door to the east and away from the source of pollution. Floor elevation should be higher than the surrounding ground, to prevent the rain inside the library.
To consider the transport facilities, and market contact and other factors. Cold storage should be built in the cool side of the hot air is better, cold storage around the water should be a good condition, the groundwater level is low, cold storage under the insulation compartment, and keep well ventilated, keep dry on the cold storage is very important. Also in the cold storage before the construction should be in accordance with the power of the refrigerator in advance to set up the corresponding three-phase power.
Second, the construction of tonnage and area of the design: logistics warehousing cold storage generally based on the development of their own enterprises in the land price is relatively convenient traffic location, cold storage around should avoid heavy pollution sources, floor should be flat, hard, dry, For the concrete, the library door should be open to open the wind, the door can be east and away from the source of pollution. Floor elevation should be higher than the surrounding ground, to prevent the rain inside the library.
Third, the volume coefficient of the description of some of the goods are full of piles, and some do not have shelves, directly to the multi-storey cargo stacking way, and cargo stacking goods such as the way the stacking of goods is much more, but the cargo center temperature and pressure need to For a long time to reach the required temperature. Its refrigeration equipment running time will be long. Relatively speaking, will increase the cost of electricity. Such as the rational use of shelves, stacking the goods, will be more energy efficient to reduce operating electricity.
Large-scale cold storage with a reasonable use of shelves, leaving a good duct, the goods placed with the cold air duct can be reasonable to meet the flow of cash, easy to achieve the average temperature.
