1500×1500 Food-Grade Membrane Filter Plate

Product Overview

The Jinwang 1500×1500 Food-Grade Membrane Filter Plate is specially developed for food, beverage and sanitary filtration applications where product purity, hygienic design, reliable sealing and efficient solid-liquid separation are critical.

Compared with conventional chamber filter plates, the membrane plate provides an additional mechanical pressing stage after the primary filtration process. Pressurized water or compressed air is introduced into the diaphragm chamber, causing the flexible membrane to expand and compress the filter cake evenly.

Within a typical 2–5 minute membrane pressing stage, additional filtrate can be removed from the cake, helping reduce residual moisture and improve overall filtration efficiency.

Hygienic Design for Food Processing

For food-contact applications, material selection and manufacturing cleanliness are particularly important.

The 1500×1500 food-grade membrane filter plate can be configured with food-contact-compatible polypropylene and suitable membrane materials, according to the specific product, regulatory requirements and filtration process.

The plate structure is designed to provide:

• Hygienic and easy-to-clean surfaces
• Stable sealing performance
• Good chemical resistance
• Low material contamination risk
• Reliable operation under repeated filtration cycles
• Compatibility with food and beverage filtration processes

Working Principle

During the initial filtration stage, the feed slurry enters the filter chambers and solids are retained by the filter cloth to form a filter cake.

After the chamber is filled:

1. The filtration stage is completed.
2. Pressurized water or compressed air enters the membrane cavity.
3. The flexible diaphragm expands and compresses the filter cake.
4. Additional liquid is forced through the filter cloth.
5. The cake becomes denser and contains less residual moisture.
6. The membrane pressure is released before cake discharge.

This secondary pressing process allows the filter press to achieve better dewatering performance without relying solely on the feed pump pressure.

Key Advantages

Food-Grade Material Options
Materials can be selected according to food-contact requirements and the characteristics of the processed product.

Efficient Cake Dewatering
The diaphragm provides additional mechanical pressure to remove more liquid from the filter cake.

Large Filtration Capacity
The 1500×1500 format is suitable for large-scale food and beverage processing operations.

Hygienic Operation
The plate can be configured for applications requiring frequent cleaning and strict hygiene requirements.

Reliable Sealing
Precision-machined sealing surfaces help minimize leakage and maintain stable filtration performance.

Customized for Different Processes
Membrane pressure, plate configuration, feed port, sealing design and filter cloth can be selected according to the specific food-processing application.
