What you need to know about filtration in the food processing industry

The filtration system in the food industry is a complex and important link. It exists in various production processes, such as raw material processing, purification during production, clarification and sterilization of products, etc. In order to ensure the safety and taste of food, food processing companies need to choose the most appropriate filtration method to ensure the smooth progress of production.

1. Classification of common filtration systems

According to different filtration objects and application scenarios, the filtration systems in the food industry mainly include the following:

  • Mechanical filtration: Remove suspended matter, particulate matter and other impurities through physical methods, such as sand filtration, activated carbon filtration, etc.
  • Membrane filtration: Use the selective permeability of the membrane to separate different components in the liquid, including microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO), etc.
  • Adsorption filtration: Use the adsorption effect of the adsorbent to remove impurities such as pigments, odors, and organic matter in the liquid.
  • Sterilization filtration: Remove bacteria, viruses and other microorganisms in the liquid through specially designed filters, such as microporous membrane filters.

2. Application scenarios of filtration systems

During food processing, we will use filtration systems in the following scenarios:

Preliminary processing of raw materials: Before food processing, the initial materials are filtered to remove impurities and contaminants, and improve the purity and safety of the raw materials, such as impurity filtration of natural pure water.

Production process: According to taste, industry standards, etc., the raw materials are filtered and purified, such as syrup, juice, etc., to ensure the cleanliness of the production environment and the quality of the product.

Sterilization: In order to ensure the shelf life and edible safety of food, the final product must be clarified and sterilized to improve the transparency and safety of the product.

3. The role of the filtration system

Filtration plays several key roles in the food industry

Improve product quality Filtration technology can effectively remove impurities, particles and undesirable ingredients in raw materials, thereby ensuring the purity and taste of the product. For example, in juice production, filtration can remove fibers and pits in the pulp, making the juice clearer and more transparent, and the taste more delicate. In addition, in dairy processing, filtration can also remove impurities and microorganisms in milk fat, improving the quality and shelf life of dairy products.

Ensure food safety ：Food safety is the focus of consumer attention and the top priority of the food industry. Through filtration, harmful substances and microorganisms in food, such as bacteria and viruses, can be effectively removed, thereby reducing the risk of food poisoning and infection. At the same time, in the process of food packaging, filtration can also ensure the cleanliness of packaging materials and prevent the intrusion of external contaminants.

Improve production efficiency Filtration technology can improve production efficiency to a certain extent. Through reasonable filtration process and equipment selection, an automated and continuous production process can be achieved, reducing manual intervention and downtime. In addition, filtration can also extend the service life of equipment, reduce maintenance costs and energy consumption, thereby improving overall production efficiency and economic benefits.

4. Common filtration systems in the food industry

Common filtration products in the food processing industry include screen filters, magnetic filters, bag filters, membrane filters, HEPA filters, etc. When choosing a filtration system, the following factors need to be considered:

  • Filtration accuracy: Select the appropriate filtration accuracy according to the quality requirements and filtration targets of the product.
  • Processing capacity: Select the appropriate filtration equipment according to the production scale and filtration volume.
  • Material and hygiene: Select materials that meet food safety standards to ensure the hygiene and durability of the filtration equipment.
