FIELD: biotechnology.
SUBSTANCE: method includes pouring the preparation into a vessel, its freezing, sublimation and finish drying on the shelves of sublimation plant. Freezing of the preparation is performed at inclined position of vessel axis relatively to vertical line for angle of 45÷75 degrees, and sublimation process is conducted during heating of shelves at the speed of 10÷15°C per hour up to temperature of 30÷35°C.
EFFECT: claimed method makes it possible to accelerate the process of drying with simultaneous reduction of energy flow.
