Compare the similarities and differences among mechanical refrigeration, modified atmosphere storage and decompression storage.

Hello, the mechanical cold storage you mentioned is a warehouse where only refrigeration units can adjust the temperature. This kind of storage prolongs the shelf life by lowering the temperature and weakening the life activities of crops. Decompression storage is to pump out the air in the warehouse by pumping equipment, reduce the oxygen content in the warehouse, weaken the life activities of crops and extend the shelf life; Modified atmosphere storage is to extend the storage time of crops by adjusting the gas components in storage, such as carbon dioxide, oxygen, nitrogen and ethylene gas. In practical use, various crop storage technologies will be comprehensively used to achieve longer shelf life and better storage effect. Zhangjiakou Ruimin Agricultural Science and Technology Co., Ltd. will provide you with cost-effective, fully automatic, stable and reliable crop storage equipment according to your actual situation.
