Cotton Cake Filter Press

Description

Cotton cake filter press is a filtering device with high filtering accuracy (0.1μ～5μ), and the filtering medium used is defatted filter cake.

Cotton cake filter press is a classic choice in the field of high-precision, low-shear filtration, especially suitable for industries that are sensitive to liquid purity, such as edible oil, biopharmaceuticals, and high-end chemicals. Its core value lies in achieving accuracy close to membrane filtration at a lower cost, but it is necessary to avoid unsuitable scenarios such as high solid content, extreme pH, and extreme temperature.

Structure

• Frame: steel plate welding and surface anti-corrosion treatment
• Filter medium: Cotton cake
• Filter plate: Reinforced polypropylene
• Volume of the filter chamber: 30~150L (Volume can be increased according to customer request)
• Filter area: 1 ~ 4 square
• Working pressure: ≤ 0.6 Mpa

Features

• High-precision filtration: can stably intercept particles larger than 0.5μm, with an accuracy close to membrane filtration, but the cost is only 1/3 of that.
• Customizable media: adapt to different materials by adjusting cotton fiber density and adding filter aids (such as perlite).
• Low shear force: suitable for heat-sensitive and easily emulsified materials (such as enzyme preparations, dairy products).

Application

With the characteristics of high-precision filtration, low shear force and customizable media, the cotton cake filter press is mainly suitable for separation scenarios with high requirements for liquid purity and gentle handling.
The following are the types of materials it is suitable for:

• Edible Oil Refining： remove phospholipids, colloids and trace metals (such as iron and copper) from crude oil.
• Pharmaceuticals and Biological Preparations： remove mycelium from antibiotic fermentation broth and clarify and filter vaccines.
• Fine Chemicals： remove impurities from high-viscosity materials (such as resins and coatings) and recover precious metal catalysts.
• Brewing： remove cold turbid substances from beer.
• Beverages： fine separation of fruit juice pulp fibers.
• Gelatin Filtration： remove tiny impurities and protect colloid structure.
