The horizontal spiral centrifuge in food processing equipment is called horizontal spiral sedimentation centrifuge. It is a highly efficient centrifugal separation equipment, which is widely used in many links of the food processing industry. The application of horizontal spiral centrifuge in food processing brings many advantages, which not only improves production efficiency, but also ensures product quality and safety. This versatile tool maximizes productivity and guarantees top-notch quality and safety in every step of food processing.
1. Working Principle
The horizontal screw centrifuge separates the materials under the action of the centrifugal field by rotating the drum and the screw at a certain differential speed in the same direction. The specific process is: the mud-water mixture enters the drum through the feed pipe and the spiral outlet. Under the centrifugal force generated by the high-speed rotation, the solid particles with a larger specific gravity are deposited on the inner wall of the drum. The spiral blades that move relative to the drum continuously scrape off the deposited solid particles and push them out of the slag discharge port. The separated clear liquid flows out of the drum through the weir plate opening. Utilizing advanced technology and precise engineering, the horizontal screw centrifuge efficiently separates materials by utilizing a centrifugal field. Through a specific process, the solid particles with a higher specific gravity are collected and pushed out of the slag discharge port, resulting in a purified liquid that flows out of the drum. This process ensures maximum separation and purification of materials, providing a cost-effective and efficient solution.

5. Specific examples of decanter centrifuges in food processing
Dairy Processing
- Whey separation: In the production process of dairy products such as yogurt and cheese, whey needs to be separated into whey and milk solids. The centrifugal force generated by the high-speed rotation of the decanter centrifuge can effectively separate whey from milk solids. Whey can be further used to prepare protein drinks and health products, while milk solids are used to make products such as cheese.
- Fat and protein separation: The decanter centrifuge can also separate fat and protein in whey to produce products such as butter and cream. This separation process improves the purity and quality of the product and meets the needs of different consumers for dairy products.
Juice Processing
- Pulp and Juice Separation: During the juice production process, the decanter centrifuge is used to separate the pulp, pomace and juice. This not only improves the clarity and quality of the juice, but also removes impurities and microorganisms in the pulp, ensuring the hygiene and safety of the juice.
- Juice Clarification and Concentration: The decanter centrifuge can also clarify and concentrate the juice. Through the action of centrifugal force, suspended particles and impurities in the juice are effectively removed, making the juice purer. At the same time, the concentration process can also improve the nutritional value and taste of the juice.
Honey processing
- Removing impurities and moisture: During honey processing, the decanter centrifuge can remove impurities and excess moisture from honey. This helps to improve the purity and taste of honey, making it purer and richer, while extending its shelf life.
Soy sauce processing
- Separation of sediment and liquid: In the soy sauce production process, the decanter centrifuge is used to precipitate solid particles and separate liquid. It can separate the sediment, residue and aerosol in the soy sauce, thereby improving the clarity and taste of the soy sauce. This separation process also helps to ensure the sanitary quality and safety of the soy sauce.
Starch processing
- Extracting starch from raw materials: Decanter centrifuges also have important applications in starch processing. For example, in the processing of starch raw materials such as wheat, potatoes, and corn, decanter centrifuges can economically and efficiently separate starch suspension from the raw materials. Through further treatment and processing, clean starch products can be obtained.
Other applications
- Decanter centrifuges can also be used in the processing of edible oil, wine and other foods. For example, in the production of edible oil, decanter centrifuges can be used to purify and separate crude oil; in the production of wine, decanter centrifuges can be used to clarify and extract wine.
The application of decanter centrifuge in food processing has the advantages of high efficiency, continuity, easy cleaning, strong adaptability, energy saving and consumption reduction, environmental sustainability and increased product added value. These advantages make decanter centrifuge one of the indispensable and important equipment in the food processing industry. Decanter centrifuge has a wide range of application prospects and plays an important role in the food processing industry. Choosing a suitable decanter centrifuge can not only improve production efficiency and product quality, but also reduce production costs and environmental pollution.
