Product Introduction
The double-screw grape crusher is a specialized juice extraction machine designed for grape processing. It uses two intermeshing screws rotating at low speed to gently crush grapes and separate juice from skins and seeds. This low-speed squeezing method achieves a high juice yield of 75-85% while minimizing the extraction of bitter tannins from seeds and stems.
All parts that contact raw materials are made of SUS 304 stainless steel, ensuring food safety and corrosion resistance. The screw pressure and humidity are adjustable to accommodate different grape varieties, maturity levels and processing requirements. The machine is also suitable for fermentative grapes and high-fiber content fruits.
The crusher features a self-cleaning design that prevents clogging and ensures continuous operation. The adjustable gap between screws allows precise control over crushing intensity. An optional seed separation system can be added for applications requiring seed-free juice.
Detailed Description of Continuous Fryer
Twin-Screw Design
Two intermeshing screws provide gentle, uniform crushing action that maximizes juice yield while minimizing damage to seeds.
Low-Speed Squeezing
5-15 rpm screw speed ensures gentle extraction that prevents bitter tannins from being released from seeds.
Adjustable Pressure
Screw gap and pressure are adjustable to optimize extraction for different grape varieties and conditions.
SUS 304 Construction
All food-contact parts are SUS 304 stainless steel, meeting food safety standards and ensuring durability.
Continuous Operation
Self-cleaning screw design prevents clogging and enables uninterrupted processing.
High Juice Yield
Optimized screw geometry and pressure profile achieve 75-85% juice yield depending on grape variety.
Low Heat Generation
Low-speed operation generates minimal heat, preserving the fresh flavor and nutrients of grape juice.
Versatile Application
Suitable for wine grapes, table grapes, and other high-fiber fruits beyond grapes.
Key Advantages
High Juice Yield
Achieves 75-85% juice yield, maximizing raw material utilization and reducing waste.
