FIELD: agriculture, animal production.
SUBSTANCE: invention refers to the fat-and-oil industry, particularly to extraction of wool fat-lanolin from the wool of fine-wool sheep. In sheep raising industry sheep wool becomes partially degreased immediately after cutting during 1-40 days in May or June when the air temperature is 20-35°C. To do this the wool is fixed on the surface of degreasing aggregate driving drum with wool fiber cut to the outside. Fencing is installed around the drum. After that the drum rotary drive is switched on and the stream of hot air is fanned on the wool heating its outer portion up to 45-60°C. Rate of centrifugal force acceleration and exposure time make up accordingly 200-400 m/sec2 and 30-60 seconds. The fat gets removed from the wool fiber and accumulates on the interior surface of fencing during the rotation process. After the drum gets stopped, fencing is removed and the fat is collected from its surface.
EFFECT: increase of fat quality obtained from wool of fine-wool sheep and cost reduction.
