DRIED MEDLAR PRODUCTION METHOD Russian patent published in 2017 - IPC A23L3/01 

FIELD: food industry.

SUBSTANCE: method involves raw material inspection, sorting, washing, cutting, microwave-convective drying. Drying takes place at the microwave-heating power and convective air blowing with the temperature of 293 K as per three stages. At the first stage, medlar which is cut into 10 mm thick quadrants is heated by microwave field with magnetron power of 180 W during 2 minutes at simultaneous blowing by the air flow at the rate of 1.5 m/s. At the second stage, medlar pieces are heated by microwave field with magnetron power of 360 W during 20 minutes at simultaneous blowing by the air flow at the rate of 0.9 m/s. At the third stage, medlar pieces are heated by microwave field with magnetron power of 600 W during 25 minutes at simultaneous blowing by the air flow at the rate of 0.3 m/s.

EFFECT: finished product of high quality.
