OIL PRESS Russian patent published in 2015 - IPC C11B1/06 

FIELD: food industry.

SUBSTANCE: oil press contains a milling chamber, an auger shaft, an oil expression chamber with a pressing cage, a mechanism for regulation of pressure in the press, an auger, the press feeder and the feeder auger shaft; the specificity is as follows: the oil press consists of two operational chambers where the first chamber represents a chamber for the source oily raw material milling and thermal treatment while the second is the oil expression chamber; the milling and thermal treatment chamber consists of three zones where the first is the source raw material charging zone, the second is the seeds moisture treatment zone and the third is milling zone; there are two augers installed in the milling and thermal treatment chamber that rotate towards each other; the thermal treatment zone is equipped with a water supply nipple; the oil expression chamber consists of a zone for source raw material charging and milling (that is under a subatmospheric pressure) and the oily raw material pressing zone; the expression zone has a cover within the raw material charging and milling zone; the pressing zone is represented by a cage body made of trapezoid-shaped cage plates having two bevels on the inner surface; the coil pitch of the auger installed inside the source oily raw material milling and thermal treatment chamber gradually decreases along the whole length.

EFFECT: invention allows to develop an oil press design allowing to reduce energy costs, decrease the overall dimensions, carry out the operations of source oil-bearing-crops milling and roasting and to increase oil yield in the oil press thermal treatment chamber.
