DEVICE FOR PRE-TREATING SQUEEZE OIL OF RICE BRAN

摘要

PURPOSE:To prevent denaturation of bran and remarkably increase oil squeeze amount and oil squeezing ratio by integrally form a bran-removing chamber and denaturation-preventing device through transfer means and providing heating means in the transfer means or denaturation preventing device. CONSTITUTION:Bran-removing action is carried out in a rice-polishing chamber 10 by air jetting from air jetting hole and bran produced there is discharged from through-hole of rice polishing cylinder into a bran-removing chamber 32 and dropped through the chamber 32 and fed to a transfer device 3 and send to feed port 35 of denaturation preventing device 3 by a screw conveyer 37. When the bran is carried by the transfer device 4, the bran is heated at about 130 deg.C which is a temperature capable of deactivating oil and fat- decomposing enzyme in the bran for about 3 sec. by a heater 38 and production of free acid is prevented by the heating to suppress denaturation of bran. Furthermore, the heater may be provided in pressure squeeze cylinder and pressure squeeze rotator.
