METHOD OF EXTRACTION OF BEEBREAD Russian patent published in 2015 - IPC A01K59/00 

FIELD: agriculture.

SUBSTANCE: for extraction of beebread from the combs the pieces of the beebread combs are separated from the frames, cooled and crushed to form separate beebread granules and wax heap with subsequent pneumatic separation of the ground mass at an air flow rate of 7.5-8 m/s, and then dried. The beebread granules in a comb are cooled irrespective of humidity and temperature until compressive strength sufficient for the comb processing of 40 kPa. At that the surface layer of beebread granules is cooled, the inner layers remain flexible properties and contribute to the separation of the wax shell of the beebread comb. The cooling time of pieces of the beebread combs is determined by the formula t_“выд”=-277.4073-1.9408·T_cooled+31.6739·W+0.0014·T_cooled ² +0.1799·T_cooled·W-0.657·W², min, where T_cooled is the temperature of the medium in which the beebread combs are cooled from 0 to -20°C; W is the beebread granules humidity in the comb of 14% to 24%.

EFFECT: reduction of energy and time and increase in the process performance, quality and quantity of the yield of the beebread granules.
