The screw press is a piece of equipment widely used in food, chemical, pharmaceutical and other fields. It uses mechanical force to remove moisture from materials, achieving an efficient and energy-saving dehydration process. This article will introduce the working principle of the screw press and explore its applications in various fields.

1. Working principle of screw press

The working principle of the screw press is based on mechanical pressure. When materials are fed into the interior of the screw press, they will be squeezed by the high-speed rotating screw and wall. Under the action of high-speed rotation, the moisture in the material is forced to be discharged to the outside. At the same time, the design of the spiral causes the material to be continuously squeezed internally, accelerating the discharge of moisture. Finally, the material becomes drier at the outlet of the screw press.

2. Application of screw press in food industry

Dehydration of vegetables and fruits: In food processing, screw presses are often used in the dehydration process of vegetables and fruits. It can effectively remove excess moisture from vegetables and fruits, extend their shelf life, and also facilitate subsequent packaging and transportation.

De-oiling of meat products: Screw presses are also widely used in the de-oiling process of meat products. In meat processing, it is often necessary to remove excess fat to improve the quality of the product. The screw press removes the fat from the meat through mechanical extrusion, maintaining the taste and flavor of the meat products.

3. Application of screw press in chemical industry

Dehydration of chemical raw materials: The chemical industry often involves the processing and handling of various chemical raw materials. In these processes, screw presses are used to remove moisture from chemical raw materials to improve the purity and stability of the products.

Wastewater treatment: In the wastewater treatment process, the screw press can be used for solid-liquid separation to separate the solid particles and moisture in the wastewater, thereby reducing the volume of wastewater and facilitating subsequent treatment and discharge.

4. Application of screw press in pharmaceutical industry

Dehydration of medicinal materials: The pharmaceutical industry often needs to dehydrate medicinal materials to improve the concentration and storage stability of medicinal materials. The screw press can efficiently remove moisture from medicinal materials to ensure the quality and efficacy of medicinal materials.

Preparation of pharmaceutical preparations: During the preparation process of pharmaceutical preparations, it is often necessary to dehydrate pharmaceutical solutions or mixtures containing moisture to obtain solid pharmaceutical preparations. The screw press can quickly remove the moisture from the drug and obtain the required drug solid particles.

5. Conclusion

Screw presses have been widely used in food, chemical, pharmaceutical and other fields due to their high efficiency and energy saving characteristics. It not only improves production efficiency and reduces production costs, but also improves product quality and stability. With the continuous advancement of science and technology, the design and performance of screw presses will continue to improve, providing more reliable dehydration solutions for production in various fields.
