Screw Press Dewatering Machines OS-180, OS-230 and OS-280 – Separators for Organic Waste

FermX screw press dewatering machines are industrial systems designed for the efficient mechanical separation of solid and liquid fractions from materials with a high water content, typically ranging from 85% to 95% moisture.

They are widely used in modern agriculture, livestock farms, biogas plants, distilleries, breweries, and agricultural and food processing facilities.

FermX screw press separators use a mechanical separation process and do not require additional flocculants or chemical coagulants. This can reduce operating costs and simplify the further processing and utilization of the separated fractions.

How Does a Screw Press Separator for Organic Waste Work?

The operating principle is based on a slowly rotating screw conveyor that moves the incoming material through a cylindrical screen drum. As the raw material travels through the working chamber, the pressure gradually increases.

The liquid fraction passes through the fine screen openings and is collected in a dedicated tank. At the same time, the solid fraction is compressed and discharged from the machine through an adjustable back-pressure mechanism.

Adjusting the back pressure makes it possible to adapt the dewatering level to the properties of the raw material and the requirements of the production process.

Key Advantages of FermX Screw Press Dewatering Machines

• Mechanical separation without additional chemicals: The dewatering process operates without chemical coagulants.

• Robust construction: The screw and screen drum are designed for industrial applications. The materials used in each model should be verified against its technical specifications.

• Adjustable dewatering level: The back pressure can be adapted to the raw material and the desired properties of the solid fraction.

• Reliable operation: The design supports continuous material flow and helps reduce the risk of screen blockage.

• Energy efficiency: The slow-running drive helps reduce component wear and energy consumption.

• Electrical protection: Overload protection and other electrical safety features depend on the configuration of the individual model.

FermX Screw Press Dewatering Machine Models

The FermX range includes three models in the OS series, designed to accommodate different production volumes.

1. OS-180 Screw Press Dewatering Machine

The OS-180 is suitable for smaller agricultural businesses, local fruit and vegetable processing facilities, and smaller biogas plants.

Its compact design allows for space-saving installation. The machine can be used to mechanically separate liquid and solid components from organic materials.

2. OS-230 Screw Press Dewatering Machine

The OS-230 is a versatile solution for businesses with medium processing requirements. It is suitable for agricultural enterprises, biogas plants, and food processing facilities.

Typical applications include the dewatering of livestock manure, digestate, brewer's spent grain, and other wet organic materials. When selecting a machine, consider the required throughput, energy consumption, and the properties of the raw material.

3. OS-280 Screw Press Dewatering Machine

The OS-280 is designed for larger production volumes and demanding industrial applications.

It is suitable for large agricultural businesses, industrial biogas plants, and companies involved in organic waste processing and recycling. Actual performance depends on the composition of the raw material, its moisture content, and operating conditions.

Main Applications of Screw Press Separators

• Dewatering cattle and pig manure: Reducing the liquid content and obtaining a solid organic fraction for further use, for example as fertilizer or bedding material, provided the relevant requirements are met.

• Biogas plants: Separating digestate into liquid and solid fractions to simplify storage, transportation, and further utilization.

• Breweries and distilleries: Dewatering brewer's spent grain, stillage, and other wet production residues for further processing.

• Fruit and vegetable processing: Dewatering press residues, mash, sugar beet pulp, and peels before further drying or pelletizing.

• Organic waste recycling: Mechanically separating wet materials to improve their further processing and recovery.

How to Choose the Right Screw Press Dewatering Machine

When selecting a screw press dewatering machine, consider the following factors:

1. Type of raw material: Manure, digestate, plant residues, or other organic materials.

2. Moisture content: The water content affects the dewatering process and the properties of the solid fraction.

3. Required throughput: The machine should match the daily or hourly processing volume.

4. Desired dewatering level: The requirements for the solid and liquid fractions determine the appropriate operating parameters.

5. Operating conditions: Available space, power supply, maintenance requirements, and integration into the existing production line.
