PRESS EXTRUDER FOR IMPROVED QUALITY PASTA PRODUCTS MANUFACTURE Russian patent published in 2015 - IPC A21C1/14 

FIELD: food industry.

SUBSTANCE: invention relates to food industry and may be used in devices for pasta products manufacture. The extruder body contains a screw with a drive outlet shaft on one side and a moulding device on the other side. The screw helical surface is divided into three steps. The first step is connected to the dough mixer. The second step is a zone for dough mass dosed supplying into the third step vacuumising zone. The screw is made of bimetal. The bimetal material on the screw helical surface side has heat conductivity coefficient 2.0-2.5 times exceeding the internal material heat conductivity coefficient. An accumulator chamber for capture of flour wastes from the third step vacuumising zone and a water jacket are installed on the extruder body. An antifriction ribbon-like insert with low adhesion properties is installed in the third screw step turn-to-turn space.

EFFECT: invention usage allows to decrease the screw heating temperature in the extruder and reduce dough adhesion in the turn-to-turn space due to friction coefficient decrease.
