UHF PRESS FOR PASTA PRODUCTS Russian patent published in 2013 - IPC A21C9/02 

FIELD: food industry.

SUBSTANCE: invention relates to food industry. The UHF press for pasta products contains a UHF generator resonator chamber with a trapezoid cross-section. The lower base of the resonator chamber is a cylindrical extrusion barrel wherein a charger auger is positioned; mounted on the above screw shaft is a moulding head consisting of a matrix, a grill and a pressure device. The extrusion barrel and the charging auger screw blade ensure a pulsing mode of UHF range electromagnetic field impact on fragmented dough. The upper base of the resonator chamber is the generator unit. It is positioned so that the radiator is turned towards the resonator chamber. Cut in the resonator chamber lateral side is a hole wherein a fragmenting mechanism is embedded. The grill of the latter covers the hole and screens radiation off. The fragmenting mechanism is positioned on the charger auger shaft with a receptacle vessel positioned over it.

EFFECT: equipment ensures reduction of energy expenditures combined with a positive modification of protein and starch properties (pasting and bonding properties acquisition).
