It is currently widely used in chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramic and environmental protection industries. It is also commonly used in the filtration process of edible oil production. It can effectively remove suspended matter and impurities in the oil. The plate and frame filter is suitable for the filtration of a variety of high-end edible oils, such as walnut oil, tea seed oil, inca inchi oil, etc.

[0003] During the actual use of the plate and frame filter, some viscous or fibrous suspensions may adhere to the pores of the filter cloth or filter plate. If they are not cleaned in time, they will easily cause blockage. Blockage will cause the filtration speed of the plate and frame filter to decrease, thereby affecting the overall production efficiency.
