The method of cryogenic refrigeration of the oils provides for refrigeration, crystallization of the waxen substances with utilization of the vapors of the cryogenic agent and stirring, seasoning, heating up and filtrating of the oils. At that the stirring is conducted with formation of the rarefaction areas, in which the cryogenic agent is directly fed for refrigeration of the oil. And the waste vapors of the cryogenic agent after the crystallization of the waxen substances in the oil purified, separated and concentrated by the baromembrane methods are used as the inert gas at storing the oil. The installation includes arranged along the run of the production process components: pumps, the tank for the purified oil, the heat-exchangers, the refrigerator, screens, the sediment collector, the intermediate collector, the mixer, the heater and the cryogenic crystallizer. Behind the heater there are additionally in series mounted the compression pump, the membrane-type generator and the filling device for filling the oils in the leakproof tare. In the first version the cryogenic crystallizer with the heat-insulation is made in the form of the closed cylindrical body having: the tangentially located to it branch-pipe for the oil feeding, inside which there is the coaxially located fitting pipe for the liquid cryogenic agent feeding; the conical detachable cover; the conical bottom and arranged along the run of the production process - the hydrocyclone, the clarifier in the fluidized layer, the settling tank, the thin layer multihydrocyclone made out of the coaxially arranged plates, the clarifier in the fluidized layer, the forced settler-separator, the aerator-flotation device-hydrocyclone, the coalescing screen and the flotation chamber formed by the conical detachable cover, in the upper part of which there is the vacuum filter. The vacuum filter represents the drum, the filtration surface of which is made out of the metal-ceramics, above which there is the knife. At that inside the drum there are partitions connected with the hollow shaft linked by the system of the pipelines with the branch-pipes used accordingly for feeding of the gaseous cryogenic agent in the coalescing screen and in the clarifier. At that the clarifier is located in the fluidized layer behind the coalescing screen. The aerator-flotation device-hydrocyclone are supplied with the branch-pipes with screens, and the settling area collector of the coalescing screen - with the branch pipe without the screen.

In the upper part of the conical detachable cover of which there is the vacuum filter and inside the body there is the two-blade stirrer fixed on the hollow shaft. At that the shape of the blades is precisely repeat the internal surface of the cryogenic crystallizer and have the holes located in symmetry on the both sides respect to the attached to their middle part perforated tubes for the cryogenic agent feeding and are placed so, that the areas of their operation are overlapping. At that the holes in the perforated tube there are only in its spherically bent part and are guided in the direction opposite to the direction of rotation of the stirrer. The invention allows to increase efficiency of the installation operation, to reduce the specific power consumption and costs of materials at utilization of the cryogenic agent and to ensure the high quality of the oil at storing.

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.
