Taking a shallow round silo for grain storage as an example, the temperature control technological measures and temperature control effects of grain silo storage are studied. The ventilation design and air conditioning temperature control design of the shallow round silo are presented, including the process measures such as silo roof ventilation, whole silo ventilation, inner circulation ventilation, grain surface temperature control, and grain cooling temperature control. The logical flow of ventilation and air conditioning temperature control processes has been formulated. It is recommended that during the design of grain storage ventilation and temperature control processes, natural cold sources, such as inner circulation ventilation and grain cooler DC cooling technology, should be used as much as possible to reduce energy consumption in the grain storage process.
