Twin-screw cooking oil refined oil equipment used in the experiment using part of the mesh and counter-rotating parallel twin screw structure, screw diameter D = 136 nun, LID aspect ratio = 6.5, the screw rotation speed n = 17 r/min, the feed rate Q = 50 a 150 kg/h, two screw axis rotation in the opposite direction, in the mesh above generate larger pressure and shear forces.Screw shaft structure, cage structure, compression ratio and discharge in cake structure as shown in figure (tanks).In the seventh paragraph of twin-screw used a pair of small pitch screw meshing completely, to help increase yield efficiency.
Squeezing cage with 34 a 50 pieces vertical parallel squeeze cage plate and gasket, oil filter clearance adjusted by 0.2 a 0.9 mm gasket, as shown in figure 3.Press cage plate have two kinds of different thickness, thick type (15 mm) thick board of as the cycle of cooling or heating jacket;Steam pipeThin (thick 5 inm) plate can increase the slit filtering area.In the two hollow screw axis, through steam injection temperature control screw.Preloading period by the use of a wide asked gap, high pressure using narrow gap.
