Double Screw Grape Juice Extractor Applications
The double screw grape juice extractor is used for continuous pressing of grape pomace after crushing or fermentation. It can also be considered for suitable fibrous fruit residues, subject to sample testing. Select the configuration according to the feed material, required throughput and desired juice/pomace separation.

How the Double Screw Grape Extractor Works
Material enters the press and moves through two counter-rotating screws. Pressure increases along the pressing zone, allowing liquid to pass through the screen while pressed solids leave through the discharge outlet. Manual or hydraulic adjustment of pomace-discharge pressure is listed by model in the table below; the setting affects extraction and juice solids.
Double Screw Juice Extractor Features
- Continuous low-speed pressing for grape pomace and other suitable feed materials.
- Adjustable discharge resistance; confirm the control method for the selected model.
- The listed product-contact material is SUS304 stainless steel; confirm the final material schedule and cleaning access.
- Screen selection and feed preparation should match particle size and fiber content.
- Actual yield and risk of blockage depend on material properties and operating settings.
Operation and Cleaning Considerations
Keep hard foreign objects out of the feed. After each run, clean retained pomace from the screen and pressing chamber according to the supplied manual. Confirm the preferred cleaning method, access points and hygiene requirements for the installation.
