CUTTING DEVICE FOR REDUCTION OF FOOD PRODUCT SIZES Russian patent published in 2012 - IPC A23N15/00 

FIELD: food industry.

SUBSTANCE: cutting device contains a carving surface whereon one places a product subject to cutting. The device contains at least one blade that moves between the first position wherein the blade cutting edge is located away from the product and between the second position wherein the blade cutting edge moves towards the carving surface by a distance sufficient for at least partial cutting of the product. The device contains the blade movement speed regulator for simplification of cutting of varied density products. The speed of the blade dropping on the product is adjusted by way of modification of air pressure in the pneumatic cylinder whereby the blade is driven. The blade movement speed may be modified in accordance with the product size and density. The carving surface is horizontally positioned. The cutting device contains an outer frame including at least one horizontal surface positioned at a specified distance under the carving surface. The pneumatic cylinder is placed under the said horizontal surface and is designed so that its inner rod may move in the vertical direction between the retracted and the extended positions below the said horizontal surface. The cutting device is detachably fixed at the low end of the pneumatic cylinder rod. The rod moves from the retracted to the extended position and drops the cutting device downwards towards the carving surface and thus cutting the product at least partially. The cutting device contains an air pressure regulator for adjustable modification of the speed whereat the rod moves between the retracted to the extended positions. The cutting device contains a pneumatics control system including at least the first and the second cocks as well as a pneumatic distributor for the rod to stay in the retracted position or return into the retracted position if the first and the second cocks are not opened.

EFFECT: invention ensures quick movement of the blade which reduces the probability of the product compression and division into unequal parts.
