A screw press is a mechanical device used to apply pressure to materials, often for the purpose of extracting liquids or shaping solids. It operates using a rotating screw mechanism that compresses the material placed within a cylindrical chamber. This type of press is commonly used in industries such as food processing, where it can extract juice from fruits, and in metalworking for shaping metal parts. The design of a screw press allows for efficient operation and high pressure application, making it suitable for various applications. It is often preferred for its simplicity and effectiveness compared to other pressing methods, such as hydraulic presses. The versatility of the screw press makes it valuable in both industrial and artisanal settings.
