Applications of Single Screw Press

A single screw press can process a wide range of materials. Its primary function is to compress materials to extract liquids from solids. Here are some materials that can be processed with a single screw press.

1. Fruits and Vegetables: It is suitable for extracting juice from fruits and vegetables such as apples, grapes, grape skins, berries, oranges, carrots, tomatoes, cabbages, gingers, spinach, and more. It is also suitable for processing other fiber-containing waste fruits and vegetables for reducing the volume and weight for further disposal.

2. Biomass and Fibrous Materials: Single screw presses can process biomass materials like wood chips, sawdust, and agricultural residues, such as corn husk, straws, grass, etc.

3. Animal Manure: These presses can handle animal manure, such as cow dung, pig manure, poultry waste, duck manure, often for the purpose of dewatering the liquid manure.

4. Sludge and Pulp Dewatering: Useful for dewatering sludge, paper pulp, biogas slurry, etc. In addition, this machine is effective for dewatering various waste residues, such as herbal residues, brewers grains, sauce residues, coffee residues, etc. But the material should contain fibers with particle sizes larger than 1.5 mm. Please note that this machine is not suitable for materials that do not contain any fibers.

Overall, the single screw press machine is a versatile and efficient solution for separating and dewatering solid-liquid mixtures in various industries, especially in fruit juice extraction, processing animal waste and various waste residues.

Working Process of Single Screw Press

The single screw press dehydrator features a single screw, offering continuous dewatering and effective shredding capabilities. The wet material is fed into the machine, and as the screw rotates slowly, it conveys the material towards the discharge end. By using force-feeding plate, it pushes the material forward and preventing it from adhering to the screw.
As the material is conveyed along the length of the screw, the pitch of the screw gradually decreases and the pressure increases. Then the liquid is squeezed out through the screen. The separated liquid is collected for further processing, while the dewatered solid continues moving along the screw to the discharge end.


In conclusion, the single screw press is a versatile and efficient solution for solid-liquid separation processes. Its continuous dewatering capabilities make it suitable for a wide range of materials, including fruits, vegetables, animal manure, agricultural wastes, paper pulp, spent grains, and more. At Tianzhong Machinery, we offer a diverse range of screw press machines for sale, capable of processing material volumes ranging from 0.2 to 50 tons per hour.

In order provide you with a customized solution that meets your specific requirements, we kindly request you to provide us with details regarding the material to process, material characteristics (fiber content), and the volume of material to process per day or per hour. Our team will offer you an ideal solution. Please feel free to contact us!
