Abstract: A system for drying fruits, spices, vegetables and the like comprises a heating compartment having an inlet for introducing a flow of drying gas and heating arrangement for elevating the temperature of the drying gas. A drying compartment is connected to and in communication with the heating compartment for holding the material to be dried. A driving arrangement is disposed in the heating compartment for directing heated drying gas through the heating compartment and into drying relationship with the material to be dried in the drying compartment. An exhaust arrangement is provided in the drying compartment for withdrawing a portion of the spent drying gas and recirculating another portion of the spent drying gas back onto the drying compartment.

Abstract: The invention comprehends a novel, adjustable, flexible inserter head having a double lumen fluid feed via a hand pump from a reservoir means. The invention includes spring means to protect the outlet of fluid from collapse of the head cover by disposition over an internal outlet rod through which the cryogenic fluid exits to the reservoir. The stationary rod can be replaced so as to shorten the inserter and vary the original extended, slim head cover to a blunter, stouter configuration.
