HYGL miscella filter is the patented product developed and produced by our company (patent No. 002302497), and is used for the purification of the miscella from the leaching plant. After filtration, the meal finescontent in miscella is reduced greatly which can reduce the phenomenon of turnover and scaling of the evaporator and improve evaporating effect of the miscella. Thus, the quality of crude extracted oil is improved significantly, and it is conducive to the comprehensive utilization of by-products. Compared with traditional miscella filter, this equipment overcomes the disadvantages of low efficiency, filter screen blocking, and hard to work continuously for a long time.
