our lemon juice machine work is crushing pulp, juice, leather through the hopper into the double helix juicer, due to the screw diameter along the bottom slag is expected to export direction gradually increase and pitch gradually reduce, when the material being spiral propulsion, for spiral cavity volume shrinking, form for material crushing.Screw spindle rotation direction from the feed hopper to slag trough direction, counterclockwise.Raw material add to the feed hopper, under the propulsion of spiral compression, the squeezing the juice through a filter at the bottom of the gravy, while the waste and the conical part of the surge tank by screw formed between the annular gap discharge, pressure regulating head along the axial movement and directly controlled by the hydraulic system.
