Stainless Steel Filter Press
A stainless steel filter press is a solid-liquid separation equipment with stainless steel as the main component. It is extensively used in industries that demand high levels of hygiene and corrosion resistance, including food processing, pharmaceuticals, fine chemicals, and environmental protection. Compared with ordinary carbon steel filter presses, stainless steel filter presses have stronger corrosion resistance, longer service life, and are more in line with clean production standards. The following is a detailed introduction to stainless steel filter presses.
Structural Composition of Stainless Steel Filter Press
Frame part
Typically constructed from 304 or 316L stainless steel, offering excellent corrosion resistance and strong mechanical durability. Including main beam, oil cylinder, plate pulling mechanism, etc.
Filter plate
Polypropylene filter plate coated with stainless steel or all stainless steel can be selected, suitable for high temperature and strong acid and alkali media. The surface is smooth and easy to clean.
Filter cloth
Choose filter cloth material that is acid and alkali resistant and can be sterilized at high temperature, according to the filter material, such as polyester, polypropylene, etc.
Hydraulic system
Controls the tightening and loosening of the filter plate, using automatic or manual control.
Control system
An optional PLC automated control system enables automatic feeding, plate tightening, pressure maintenance, plate shifting, and other functions, minimizing the need for manual operation.

Core Advantages of Stainless Steel Filter Press
Strong corrosion resistance
Stainless steel has excellent corrosion resistance to acid, alkali, and salt media, and is especially suitable for treating highly corrosive filtrates, such as pharmaceutical mother liquor, fruit juice, cosmetic raw materials, etc.
Comply with GMP, FDA, and other hygiene standards
In the food and pharmaceutical industries, stainless steel filter presses are widely used in protein precipitation, plant extract filtration, blood product decolorization, and other process links. Its sanitary design ensures no dead corners, easy cleaning and disinfection, and avoids cross-contamination.
Long service life
304 or 316L stainless steel has excellent mechanical properties; the filter plate is not easy to deform, the overall durability of the equipment is high, and the maintenance cost is reduced.
Strong customizability
According to the process requirements of different materials, you can choose plate and frame type, chamber type, diaphragm press type stainless steel filter press, support gas-assisted pressing, hot water insulation, closed structure, and other functional expansions.
Selection Suggestions
- Filter plate size and quantity: determine the filtration area and processing capacity.
- Material selection: such as 316L for high chloride ion concentration medium environment.
- Automation degree: whether automatic plate pulling, automatic unloading, etc., are required.
- Sealing performance: especially when handling volatile or toxic liquids, a fully enclosed structure should be selected.
- Filter cloth matching: select the appropriate pore size and material according to the material characteristics.
