A control system and method for a frostless, multivariable coupling and heat pump-based hot blast stove are used for grain drying. A first heat exchanger, a second heat exchanger, a main solution pool, corresponding pipelines, and a temperature detector are configured in the control system. A first heat pump unit, a second heat pump unit and a third heat pump unit are formed. A preheating zone, a low temperature zone, a medium temperature zone and a high temperature zone are sequentially formed on an air supply pipeline from a fresh air inlet to a fresh air outlet. A frostless operation procedure is provided. Through the configuration, the control system and method for a frostless, multivariable coupling and heat pump-based hot blast stove can implement heat supply in a gradient heat-circulation preheating mode and a gradient heat-circulation frostless mode.

A vacuum drying apparatus has a rigid bin structure within a flexible membrane liner arranged to store particulate material therein. An exhaust passage and air inlet passage communicate through the envelope in sealed relationship with the envelope. The air inlet passage is adjustably flow restricted relative to the exhaust passage so as to enable a flow through material in the liner when applying vacuum pressure to the exhaust passage, for example using a centrifugal fan. The air inlet passage communicating with an upper manifold within the upper portion of the bin structure and the exhaust passage communicating with a lower manifold within a lower portion of the bin structure.

Disclosed are a method and/or system for automatically controlling ventilation of a grain storage bin to maintain the grain parameters within a predefined range. The disclosed system includes a ventilation control system and a plurality of ventilation fans installed to the storage bin. The ventilation control system includes a fan switch control unit, a weather station, and a plurality of grain characteristics monitoring devices. The fan switch control unit includes a first switch and a second switch to constantly operate the plurality of ventilation fans on receiving an alarm signal from the weather station and/or the grain characteristics monitoring devices. The weather station transmits the alarm signal to deactivate plurality of ventilation fans when the captured external parameters deviate from predefined external temperature-humidity range. The grain characteristics monitoring devices transmit the alarm signal to activate plurality of ventilation fans when the captured grain parameters deviate from predefined grain temperature-humidity range.
