AUGER COUNTERFLOW EXTRACTOR FOR FIBROUS MATERIALS Russian patent published in 1995 - IPC

FIELD: textile and food-processing industries. SUBSTANCE: in the auger counterflow extractor for fibrous materials the coil of the auger of the input section and/or of the horizontal section of the housing is made with the output member. The output member is fastened cantilevered on the shaft of the corresponding auger for the axial resilient deformation along the length equal to that of the circumference of the cross-section of the auger shaft. Besides, the auger shaft with the output member fastened cantilevered is made tapered along the plane of fastening the output member and with the cylindrical cavity. The axis of the cylindrical cavity is parallel to the auger axis. The depth is chosen exceeding the axial length of the cantilevered output member. The output member is equipped with a cylindrical guide. One end of the cylindrical guide is connected with the cantilevered output member. Its second end is freely placed for displacing in the cavity of the auger shaft. The length of the cylindrical guide is chosen not less than the axial length of the cantilevered output member and not more than the cavity depth of the auger shaft. EFFECT: enhanced quality of processing fibrous materials of vegetable and animal origin. 1 cl, 3 dwg
