Introducing the Stainless Steel Plate Frame Multi-layer Filter, a pinnacle of precision liquid filtration technology. This advanced machine boasts a stunning mirror-polished finish and harnesses the power of filter cloth or membrane filtration. With its robust sealing strips and high-performance stainless steel pump, it is tailored to excel in solid-liquid separation and liquid filtration. Perfectly suited for a diverse range of sectors including laboratories, fine chemicals, pharmaceuticals, traditional Chinese medicine extraction, food, and cosmetics, this filter represents the epitome of efficiency and versatility.
Working Principle
The ingenious design of our filtration machine ensures optimal efficiency. Each sealed filtration chamber is filled with suspension, and under precise pressure, the filtrate seamlessly passes through the filtering layer and membrane. It then exits through the outlet while the residue forms a robust filter cake within the plate frame. This sophisticated process guarantees effective solid-liquid separation, delivering unparalleled filtration results.
Features
Crafted from premium-grade stainless steel materials such as SUS304 or SUS316L, this machine is built to withstand corrosion and endure the test of time. The innovative threaded structure of the filter plates allows for effortless replacement of filtering materials, tailored to the specific filtering medium and production process—be it per-filtration, semi-filtration, or fine filtration. Achieve sterile filtration effortlessly with direct use of micro-porous membranes. Customize the number of layers based on filtration volume for optimal production. With leak-proof plate frame filters, this machine guarantees no loss of liquid material, exceptional liquid clarity, and the option to create bespoke multi-stage filtration devices. Begin with coarser materials and transition to finer ones for time-saving, precision filtration. Equipped with silicone (fluorine rubber) sealing rings, it ensures robust heat resistance, non-toxicity, and impeccable leak-proof performance. For ultimate convenience, opt for a custom automatic return device. When the pump ceases operation, simply open the return valve to discharge all sediment automatically, complete with an air exhaust function. The machine also offers back-washing with clean water from the return pipe, streamlining maintenance and enhancing user experience.
