METHOD FOR VACUUM DRYING OF SEA BUCKTHORN Russian patent published in 2022 - IPC A23L3/40 

FIELD: food industry.

SUBSTANCE: invention relates to the food industry. A method for bare-vacuum drying of sea buckthorn is proposed, according to which sea buckthorn is dried by infrared rays at a temperature of 40°C. During drying with infrared rays, four successively alternating drying cycles are carried out by air injection - vacuuming. Initially, air is injected in the cycle, and then the evacuation process is carried out. Air is injected into the chamber with a relative humidity of 5% to an excess pressure of 20 kPa in the first cycle, 40 kPa in the second cycle, 60 kPa in the third cycle and 80 kPa in the fourth cycle. With each process of air injection, sea buckthorn is kept for 3 minutes, and in the process of evacuation, the residual pressure is adjusted to 6 kPa. The duration of the evacuation process is 50-70 minutes.

EFFECT: invention makes it possible to obtain a product of uniform consistency with a moisture content of not more than 5% without damaging the berry shell.
