苏联选用钢板仓作为气调贮存粮食的仓库.气调所用的混合气体中的二氧化碳气体量为12—13%,氮气85—86%,其余为氧气.氧气和二氧化碳的浓度可以有不同值,随保藏的粮食不同及贮存温度不同而变化.贮存稻谷及油料作物时,二氧化碳的含量通常在5—12%的范围内.燃烧天然气是得到气调所用的混合气体的最经济的方法.在钢板仓内气调贮存高水分稻谷时(水分不大于22%),在低氧(小于1%)及原始粮温为20℃的条件下,要发生两个过程:一是混合气体的保藏过程,二是由于稻谷的呼吸使二氧化碳积累而引起的自身保藏过程.这时微生物区系组成也发生变化:霉菌被芽孢杆菌、酵母菌、类酵母菌和球菌所取代.
The Soviet Union uses steel silos as a storage space for gas storage. The amount of carbon dioxide gas in the gas mixture used is 12-13%, nitrogen 85-86%, and the rest is oxygen. The concentrations of oxygen and carbon dioxide can vary with The storage of food varies with the storage temperature, and the storage of rice and oil crops, the content of carbon dioxide is usually in the range of 5-12%. Burning natural gas is the most economical method to get the gas mixture used in the atmosphere During the storage of high-moisture paddy with internal atmosphere (water not more than 22%), under the condition of low oxygen (less than 1%) and original grain temperature of 20 ℃, two processes take place: one is the preservation of mixed gas, Is the process of self-preservation caused by the accumulation of carbon dioxide due to the respiration of rice, when the composition of the microflora also changes: the mold is replaced by Bacillus, yeast, yeast and cocci.
