A system and method for drying and utilizing spent grain includes an agitation device having an elongated semi-cylindrical mixing chamber with a motor-driven shaft and a plurality of agitators. A lid is hingedly positioned along the top end of the chamber and is connected to the dehumidification system by a pair of air ducts. An air filtration device is interposed between the air output of the agitation device and the air input of the dehumidification system. A method of drying spent grain includes the steps of pouring spent grain into the interior space of the chamber, securing the lid in the closed position, agitating the grain inside the chamber via the agitators, removing damp air from the interior space of the chamber, and introducing dry warm air to the interior space of the chamber until a moisture content of the spent grain achieves a user specified level.

An apparatus and method for dehydrating biological materials, such as vaccines and microorganism cultures, in which the materials are dehydrated in an evacuated container which is in a microwave waveguide that is open to the atmosphere. The apparatus comprises means for freezing the container of biological material, a microwave generator, a waveguide, means for introducing the container into the waveguide, means for applying a vacuum to the container and means for removing the dehydrated material from the waveguide. In the method of the invention, the container of biological material is put in a microwave waveguide open to the atmosphere, a vacuum is applied to the container, the material is frozen and is radiated to dehydrate it. The dehydrated material is then removed from the waveguide.

The present disclosure relates to environmentally-clean thermal drying systems and methods.
