Systems and methods of grain drying using radio frequency waves while maintaining low temperature are disclosed herein. Specifically, the system and method includes minimizing temperature increases caused by dielectric radio frequency heating while increasing intermolecular hydrogen bond disruption. Further disclosed herein are devices systems and methods for removing moisture from a material via radio frequency electromagnetic wave exposure.

Dehydration and drying are some of the oldest methods of preserving food and other biological materials such as proteins and both live and dead live microorganisms or their metabolites. The invention disclosed herein seeks a method of further improving the process of preserving biological material by combining the freezing or freeze-drying process with a partial infrared dehydration step. By using infrared radiation energy to perform simultaneous blanching and dehydration, the drying speed is greatly increased and better cellular and molecular integrity is maintained. The invention herein is also particularly useful in connection with cannabis and hemp.

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.

An apparatus for connecting a heater to a grain bin aeration fan features a multi-piece adapter device having a connection adapter with inlets for receiving flexible ducts from a heater. The connection adapter can be used on its own to directly interface with a grain bin aeration fan of a first size, or can be used in combination with a cooperative sizing adapter to adjust an effective outlet size of the adapter to better fit a grain bin aeration fan of a different second size. An ambient air intake in the connection adapter entrains ambient air into the heated air stream.
