FIELD: food-processing industry.
SUBSTANCE: method involves forming basic product by extruding it immediately into sublimation chamber zone with pressure above triple point; providing evaporative freezing of product with pressure below triple point and sublimation drying thereof in superhigh frequency energy field, with following removal through sluice gate; providing additional extrusion of product through coaxial channel peripheral with respect to central channel; introducing product with increased content of dry substance via peripheral coaxial channel for further forming of slightly dried carcass of product; feeding product with low dry substance content via central channel.
EFFECT: improved quality of product and reduced power consumption.
