Okara Dewatering Machine, Filter Press for Slurry Dewatering

The Okara Dewatering Machine is a chamber filter press designed for solid–liquid separation. It uses hydraulic pressure to compress slurry between filter plates to form a filter cake and discharge clear filtrate. It is available in automatic and semi‑automatic configurations and is intended for industries such as food processing, wastewater treatment, mining, chemicals and pharmaceuticals.

The machine feeds slurry into a series of filter chambers formed by plates and filter cloth. Hydraulic pressure compacts the solids into a cake while liquid passes through the cloth and is collected as filtrate. After filtration, the plates open and the solid cakes are discharged. The system uses an electric hydraulic control for plate pressing and release.

Key specifications: type — integrated electric hydraulic chamber filter press; condition — new; voltage — 380V/50Hz; power — 2.5 kW; weight — 840 kg; dimensions — 2380 × 900 × 850 mm (L×W×H).

Two modes are offered: automatic and semi‑automatic. Automatic mode controls feed, pressurization, cake formation, plate opening and closing via programmable controls with minimal operator input. Semi‑automatic mode requires manual intervention for some steps (for example starting/stopping feed or opening plates).

It is suitable for a wide range of slurries including okara (soy pulp), food processing residues, municipal and industrial sludge, mineral slurries, chemical precipitates and pharmaceutical suspensions. Performance depends on solids concentration, particle size and rheology.

Throughput depends on plate size/number, slurry solids content, cake thickness and cycle time. Because these variables differ by application, capacity is typically specified after sample testing or by providing process parameters so the supplier can size the unit correctly.

Final cake moisture varies with the slurry characteristics, use of conditioning agents (polymers), applied pressure and cycle time. The machine can substantially reduce free water, but precise achievable moisture content should be determined with trial runs on your specific slurry.

Routine maintenance includes daily inspections for leaks and damage, regular cleaning of filter cloths, checking and replacing worn gaskets or filter plates, monitoring hydraulic oil level and condition, and scheduled servicing of valves and pumps. Follow the manufacturer's maintenance schedule and record keeping for best results.

Filter cloth selection depends on particle size, chemical compatibility and desired filtrate clarity. Common materials include polyester and polypropylene cloths with various weaves. Cloths are replaceable and suppliers can recommend or supply the appropriate type for your slurry.

The unit requires a level, load‑bearing floor with adequate space for the machine dimensions and operator access. Electrical supply: 380V/50Hz three‑phase. Provide inlet feed piping, a filtrate collection line, and a means to handle discharged cakes (e.g., conveyors or bins). Specific site preparation details should be confirmed with the supplier.

Typical safety features include hydraulic overload protection, emergency stop, interlocks to prevent plate opening under pressure, protective guards around moving parts and clear operator controls. Operators should be trained and local safety procedures followed.

Yes. Consumables such as filter cloths, gaskets, plates, seals, pumps and hydraulic oil are commonly available. Ask the supplier for recommended spare parts list and lead times to minimize downtime.

Yes. Common customizations include different plate sizes and counts, cloth materials, automation/control options, corrosion‑resistant materials, and integrated feed or cake handling equipment. Provide process details to the supplier for a tailored solution.

Cake removal is done when plates open and the cakes fall out or are removed manually/automatically depending on setup. Sticky or fibrous materials may benefit from pre‑treatment (thickening, polymer conditioning) and appropriate cloth selection to improve cake release. Discuss your material characteristics with the supplier for best practices.

Warranty terms and after‑sales support vary by supplier. Typical offerings include a limited warranty on manufacturing defects, spare parts supply and technical support for installation and commissioning. Contact the vendor for specific warranty duration, service packages and response times.
