PRESS-EXTRUDER Russian patent published in 2005 - IPC

FIELD: food-processing industry;equipment for processing agricultural products.

SUBSTANCE: the invention is pertaining to equipment for processing agricultural products by extrusion and may be used in the food-processing industry. The Press-extruder contains a body of the main drive unit with a loading hopper and a feeding device, a composite feed screw and a cylindrical body of a feed screw consisting of split components. In the place of coupling of the components of the feed screw body there are the ring-type grooves for rigid fixation in them of a ring with the internal chases directed at an angle to the axis of the ring. The ring has adjustable thickness and is made in the form of several rings and washers, the total thickness of which is equal to the width of the ring-type groove. The invention ensures enhanced efficiency and stability of the extrusion process at changing of the process technological characteristics and physical-mechanical properties of the processed materials.

EFFECT: the invention ensures enhanced efficiency and stability of the extrusion process at changing of the process technological characteristics and physical-mechanical properties of the processed materials.
