The invention discloses a double-screw cold-pressing expeller configured by variable pressing bolts. The double-screw cold-pressing expeller configured by the variable pressing bolts comprises a rack,a driving device, and a pressing device; the driving device is installed on the rack, the pressing device is installed on the rack, the pressing device comprises a pressing cage and two spindles, thetwo spindles extend along the front and back direction and are parallelly arranged in the pressing cage, the spindles are connected with the driving device in a driving mode, and the driving device drives the two spindles to rotate in the opposite direction; and a plurality of resistance rings interlacedly arranged are arranged on each spindle in a sleeving mode and are spaced along the axial direction of the spindle, each resistance ring and the corresponding spindle is circumferentially fixed by a key, and a keyway of the plurality of resistance rings fixed on the same spindle and the angleof displacement [gamma] of the resistance ring center line are gradually increasing arranged along the front and back direction. The double-screw cold-pressing expeller configured by the variable pressing bolts aims to provide an oil expeller with low power consumption and high material adaptability.
Description
technical field [0001] The invention relates to the technical field of oil pressing equipment, in particular to a twin-screw cold press with variable pressing screw configuration. Background technique [0002] Fat is one of the seven major nutrients necessary for the normal operation of the human body. Vegetable oil is an important source of fat required by the human body, and its quality directly determines human health. The preparation and processing technology of vegetable oil has a long history, and currently mainly includes solvent extraction method and mechanical pressing method. Due to the complex process and the inevitable solvent residues in the oil and cake, the solvent extraction method affects the health of the body. Therefore, the application of mechanical pressing method to produce vegetable oil is more and more extensive. [0003] Since the beginning of the last century, since V.D.Anderson of the United States invented the first continuous screw oil press, t...
