A loop-type flash drying apparatus configured to dry an object to be treated with a gas by supplying the object into a gas stream circulating in a loop-type drying pipe, wherein the loop-type flash drying apparatus includes: (i) a loop-type drying pipe; (ii) a feeding port configured to feed an object to be treated into the drying pipe; (iii) a second blowing port configured to blow a gas into the drying pipe; (iv) a discharge port configured to discharge the object from the drying pipe; (v) a discharge region formed by the drying pipe and the discharge port; and (vi) a first blowing port through which a gas for accelerating a gas flowing in the discharge region is linearly blown toward the discharge region.

Apparatus and methods for bulk processing items on a conveyor belt using an angled axial fan that extends obliquely into a processing chamber and includes a curved back wall forming an air flow chamber. The angled axial fan enhances air flow around a product being processed on the conveyor belt. A heater employs shrouds and a series of baffle plates held together using a connecting pin to heat circulated air in a low-pressure area below the conveyor belt. Baffles in an upper chamber mix and direct heated, circulated air over the conveyed product.

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.
