Key Features of This Model:
- For materials that are particularly difficult to press, single-screw designs often face challenges such as shaft jamming, preventing material from advancing and leading to poor dehydration performance. To address this, our company has specifically developed and manufactured the twin-screw design. It is especially suitable for handling challenging materials such as fish oil, fish paste, decayed meat products, potato skins, feed, sugar beets, and more.
Notes on Machine Operation:
- Processing Capacity: Results vary depending on sludge or material properties, types, and solid content concentration.
- Driving Power: Designed to adjust based on material properties and concentrations.
- Automation: Equipment can integrate automation for reduced labor and operational costs, achieving "AI Industry Smart Operation" for maximum business efficiency.
- Please ask for the actual installation dimension drawing before ordering..

Single-Screw Dehydration Principle for High-Fiber, High-Ash Residue in Industrial Processes:
- The single-screw press utilizes the principles of screw conveyance and compression. By gradually increasing pressure, the water in the material is forced through a metal screen, achieving dehydration.
- Low-Pressure Zone:
The first section is the low-pressure zone, where free water within the material is discharged. - Medium-Pressure Zone:
The second section is the medium-pressure zone, where the material undergoes pre-compression into a cake-like form. - High-Pressure Zone:
The third section is the high-pressure zone, where the material is pressed and compressed further to reduce its moisture content.

- Highly Efficient Dehydration Equipment:
This machine is an extremely high-performance dehydration device, especially suitable for products in various industries that require stringent control of moisture content. - Exceptional Dehydration Efficiency:
One of its standout features is its high dehydration rate, with some materials achieving over 40% dryness after processing. This brings considerable economic benefits to those involved in recycling and reusing waste. - Secondary Squeeze Dehydration:
Sludge pre-dehydrated by belt filter or screw press systems can undergo secondary squeezing to further reduce moisture content, from an initial maximum of 89% to a range of 32–71% (depending on the sludge type). This effectively reduces volume and lowers subsequent disposal and transportation costs. - Patented Discharge Design:
Ensures fixed internal pressure without issues of synchronized rotation. - Archimedean Screw Principle:
Designed with a specialized screw combination for various sludge and materials, providing large capacity, stable performance, and low moisture content. - Innovative Self-Cleaning Screen:
The core technology lies in the interaction between the screw and screen, achieving a self-cleaning function. A unique device allows the screw to agitate materials, preventing shaft wrapping and enabling material particles to dislodge blockages during advancement. - The screen is resistant to clogging and imposes no special requirements on feed concentration, viscosity, abrasiveness, particle size, or fiber length.
- The rear discharge control system is distinct from commonly used spring, hydraulic, or handwheel systems in the market. It adopts a low-maintenance pneumatic device with a specific design to achieve effective "back pressure" control for material pressing. By setting a predetermined pressing pressure, the device automatically adjusts the pressing force, ensuring consistent discharge quality and preventing fluctuating dryness. Additionally, this press separator utilizes a sequential compression principle, making it particularly suited for continuous production lines and avoiding the limitations of traditional presses that require batch processing.
- The machine supports both intermittent and continuous operation, ensuring stable production capacity and high efficiency. It also features a cleaning system, with an intermittent screen washing function or a pre-shutdown cleaning system that minimizes clogging and requires minimal water consumption.
- The press screen is composed of two semi-circular segments, which can be easily disassembled for thorough cleaning, making it especially suitable for food and fruit/vegetable processing industries.
- The machine is highly durable and effective in handling complex residue materials without wear, ensuring smooth water discharge. This is achieved through the efficient cooperation between the screw and the screen, realizing the goal of pressing and separation.
- The SY2 Spiral Progressive Screw Press is an advanced screw press designed for continuous operation. It is capable of extracting liquids from organic materials and separating solid-liquid components in inorganic materials, representing an innovative and cutting-edge design in screw press technology.
- The machine can also be equipped with a steam heating system or an electric heater (optional) to further reduce moisture content and effectively increase processing capacity.
