Method and device for drying materials

A method for drying materials of vegetable, animal origin, fish and sea food, comprising repeating at least twice cycles, each cycle comprising a sequence of performing operations in enclosed space

• heating up material to a temperature not leading to denaturation of material origin quality characteristics,
• quick vacuum treatment,
• exposure of material after vacuum treatment wherein
• at an end of operating cycle a vacuum relief to atmospheric pressure is performed, wherein
• heating up and vacuum relief of that material is performed with dried air heat medium with the temperature to 300° C.

• quick vacuum treatment,
• exposure of material after vacuum treatment wherein
• at an end of operating cycle a vacuum relief to atmospheric pressure is performed, wherein
• heating up and vacuum relief of that material is performed with dried gas heat medium with the temperature to 300° C.

An apparatus for drying of materials of vegetable, animal origin, fish and sea food comprising

• at least two drying chambers with pressure-proof doors each of
• said at least two drying chambers is connected by means of
• pipelines with quick-response valves to receiver, heat exchanger-condensers, condensate tank,
• vacuum pump,
• device for heat medium heating up, wherein
• the device for heat medium heating up is installed in a separate chamber with heat insulation and connected by means of heat insulated forcing air ducts with quick response valves to inlet of each drying chamber, inside each of said drying chamber a container with tube along the axis of rotation is installed with rotating capacity, wherein an either tube surface is perforated to supply with heat medium and a lateral surface of a container body is netted to remove the heat medium.
