Warehousing management is the key to good or bad warehousing effect. During storage, the temperature, relative humidity, gas composition, ventilation and circulation system in the warehouse should be regulated and monitored. The temperature fluctuation in the warehouse should not exceed 0.5℃; Relative humidity management focuses on humidifiers and monitoring systems. Humidification should be started in time, and oxygen should be quickly reduced after gas composition management, so that the proportion of oxygen, carbon dioxide and nitrogen can finally reach a proper balance. During storage, the sensory properties, hardness, total sugar content, water loss rate and decay of raw materials should be observed, and various records should be made, summarized and analyzed to guide storage management.
