Stainless Steel Coated Filter Press for Filtering Surimi

The main purpose of surimi (fish paste) filtration is to improve the purity and quality of surimi, remove solid impurities, and make it more suitable for food processing and the production of high-value-added products. A stainless steel-coated filter press can be used to filter fish paste. This equipment is particularly suitable for processing liquids with high viscosity and high solid content.

Purpose of Filtering Surimi

Remove impurities
The primary goal of filtration is to remove solid impurities in surimi, such as fish bones, fish scales, fish tendons, fish skin, etc. These impurities will affect the taste and fineness of fish paste, especially when producing high-demand foods such as fish balls and fish cakes; impurities must be minimized.
Improve the purity of fish paste
By filtering, the purity of fish paste can be significantly improved, making the product more uniform and fine. High-purity fish paste is the key to making high-quality fish products, and filtered fish paste can achieve more ideal processing standards.
Improve the taste of fish paste
Fine fish paste can provide a better taste, especially in products such as fish balls and fish cakes, where taste is the key factor in determining quality. Filtered fish paste can ensure that there are no obvious particles or roughness, making the product smoother.
Facilitate subsequent processing
Filtered fish paste is easier to carry out subsequent processing, such as seasoning, molding, and packaging. Fish paste without impurities is more stable in mechanical processing, it is not easy to clog equipment, and it improves production efficiency.

Specific Processing Process

Pretreatment: Surimi usually needs pretreatment, such as pre-screening or coarse filtration, to remove larger particles, which can reduce the load of the filter press and improve the filtration efficiency.

Choose the right filter cloth: The solid particles in the surimi may be fine, and the right filter cloth material and pore size need to be selected to ensure effective separation of solids and liquids. Commonly used filter cloth materials include polypropylene, nylon, etc.

Filtration process: The surimi enters the stainless steel coated filter press through a pump, and the liquid passes through the filter cloth under pressure while the solids are trapped to form a filter cake. Depending on the viscosity and particle distribution of the surimi, the feed pressure and filtration time can be adjusted appropriately.

Filter cake treatment: After the filtration, the filter cake can be further processed as needed or sold directly as a by-product, such as fish meal raw material. The liquid part can be used to extract fish oil or further processing.

Advantages of stainless steel coated filter press

Strong corrosion resistance
Stainless steel has excellent corrosion resistance, especially when processing materials containing salt, acidic, or alkaline substances (such as fish paste); stainless steel materials can resist corrosion and extend the service life of the equipment.
Meet food safety standards
In the field of food processing, such as fish paste, the hygiene of equipment is crucial. Stainless steel materials have good biocompatibility, meet food-grade standards, and can effectively prevent material contamination.
Easy to maintain and clean
Stainless steel is smooth and does not easily absorb impurities, so it is easy to clean and maintain during use. Especially in the food processing industry, equipment often needs to be thoroughly cleaned to prevent contamination and cross-infection.

Conclusion

In summary, the surimi filtered by the stainless steel coated filter press will be more delicate, and the impurity content will be greatly reduced, which can greatly improve the quality of the surimi and is suitable for subsequent deep processing or directly used in the production of high-end fish products.
