A dehydrating apparatus suitable for dehydrating food and other biomass products comprises a dehydrating chamber, a vacuum assembly, a magnetron assembly, an infrared heating assembly, a heated air circulation assembly, and a controller. The magnetron assembly is electromagnetically coupled to the dehydrating chamber and is operable to transmit microwave energy into the dehydrating chamber. The vacuum assembly is fluidly coupled to the dehydrating chamber and is operable to reduce the air pressure within the dehydrating chamber. The infrared heating assembly is thermally coupled to the dehydrating chamber and is operable to radiate infrared energy into the dehydrating chamber. The heated air circulation assembly is fluidly coupled to the dehydrating chamber and is operable to circulate heated air within the dehydrating chamber. The controller is communicative with and programmed to operate the magnetron assembly, vacuum assembly, infrared heating assembly and heated air circulation assembly to first reduce pressure within the chamber, then simultaneously transmit microwave energy, radiate infrared energy, and circulate heated air inside the dehydrating chamber upon specific dried product drying procedure.

A round dryer for drying workpieces has a helically revolving workpiece passage in a work container and is provided with a heating device. The work container is closed at its upper side.

A system for drying wet food articles (such as produce) is disclosed herein. The system can comprise a turntable capable of rotating multiple barrel stations. The system can comprise various loading, drying, dumping, and cleaning positions, and the barrel stations can be rotated to each of these positions. The present disclosure also describes various methods for drying wet food articles utilizing such systems.

Embodiments provide a multi-pass kiln with two or more chambers, an entrance and an exit at a proximal end of the kiln, and a reciprocal flow path extending through the kiln from the entrance to the exit. Lumber charges traveling along the reciprocal flow path may travel in a first direction along one side of the heated second chamber before traveling in a substantially opposite second direction along the opposite side of the second chamber. The distal end of the kiln may be substantially sealed, and a pressure differential between the distal end and the proximal end may draw moist heated air from the heated chamber toward the exit and entry to preheat and/or condition lumber charges traveling through the first chamber.
