1.Rice bran oil dewaxing, degreasing and fractionation technology
Crystallization section
Cooling under the preset parameters and process control, it is implemented with the help of the coil cooling medium circulation and its design parameters and equipment depends on the requirements of the quality of the crude oil and refined products. Crystallizing tank is equipped with frequency conversion governor, which control the speed, decide the cooling curve based on the requirement of the quality of oil and material. All the cooling crystallization is controlled by computer intelligent controller, in strict accordance with the cooling curve, so the crystallization effect is good, so saving amount of investment, and improving the economic effect.
2.Dewaxing, degreasing and fractionation technology
After crystallization, put slurry into the mode filter to filter. Filter operation is divided into four steps, they are feeding, filtering, squeezing and slag discharge process. When the filter cake formed, the filter liquor began to filter after clarification, when the filter cell is full of filter liquor, then convey to the oil pump. By compressed air or liquid oil and squeeze the filter cake, when the residual liquid grease basic after discharge from the filter cake, and relieve the pressure in the filter press, open the filter , drop the stearin into the stearin collection box.
