Fast Hygienic Compact Durable

QLD Dewatering Screw Press delivers automated 24/7 sludge dewatering at about 500L/h for food-industry effluents, reducing labor, water use and odors while running quietly and energy-efficiently. Its compact, enclosed SUS304 stainless-steel construction integrates the electrical cabinet, disposal tank and dehydrator with a slow-running screw and stacked-ring filter for jam-free operation, easy maintenance and standard export carton packaging. Backed by a 1-year warranty, it’s simple to install and adjust (screw speed and back-pressure gaps) to control cake moisture and meet varied process needs.

Automatic Food Dewatering Press

The QLD Dewatering Screw Press is an automatic SUS304 screw-press dewatering machine for the food industry with a 500L/h capacity and 1-year warranty, integrating the electrical cabinet, disposal tank and enclosed dehydrator to reduce footprint, odor and maintenance. Its stacked fixed-ring and moving-ring filter design with polymer-assisted filtration and adjustable screw speed/back-pressure enables continuous 24-hour, jam-resistant operation that produces consistent mud cakes while lowering power consumption and noise. Designed for easy daily maintenance and compatibility with sludge pumps and dosing systems, it delivers labor- and water-saving sludge thickening, reduced emissions and extended service life for efficient wastewater treatment.

Automatic Food Dewatering Press

The QLD Dewatering Screw Press is an automatic stainless steel (SUS304) screw press designed for food-industry sludge dewatering with a 500 L/h capacity, enclosed operation to reduce odors, and an integrated electrical cabinet for compact installation. Its slow-running screw and moving-ring filtration system prevents jamming, reduces noise and power consumption, and enables continuous 24-hour operation with adjustable back pressure and polymer dosing to control cake moisture. Built for easy maintenance and compatibility with standard accessories (sludge pump, polymer dosing pump, washing pump), this unit lowers labor demand and cleaning water use while improving the working environment.

Efficient Hygienic High-capacity Durable

Built by a dedicated R&D team with food-grade standards and a one-year warranty, the QLD Dewatering Screw Press combines precision engineering and corrosion-resistant materials to deliver reliable 500L/h performance for food processing. It automates solids-liquid separation with adjustable screw speed, a low-energy drive, easy-clean design, sealed bearings and PLC controls for continuous hygienic dewatering and minimal maintenance. Key features and advantages: 500L/h capacity, automatic operation, food-grade stainless steel construction, compact footprint, energy-efficient motor, quick disassembly for sanitation, and one-year support for uptime and parts.

Material introduction

The QLD Dewatering Screw Press is constructed primarily from SUS304 stainless steel, providing food-grade corrosion resistance and long service life for continuous 24-hour operation. Key components—screw shaft, fixed and moving rings, back pressure plates and disposal tank—are machined from durable stainless material and engineered to resist clogging while allowing easy cleaning with minimal wash water. The integrated electrical cabinet and enclosed dehydrator enhance hygiene by reducing odors and environmental exposure, simplifying maintenance and installation for food and beverage applications.

FAQ

What kinds of food materials can the Automatic Screw Press Dewatering Machine handle, and what application scenarios is it best suited for?

The machine is designed for food-grade dewatering of soft to semi-solid wastes and by-products such as fruit and vegetable pomace, juicer pulp, tomato paste residue, spent grains, okara (soy pulp), cooked food waste from restaurants or catering, and some aquaculture or seafood processing residues. Typical application scenarios include restaurants and hotels, juice and sauce production lines, fruit and vegetable processing plants, small- to medium-scale food manufacturing, and waste reduction at central kitchens or catering facilities.

What does the stated capacity of 500 L/h mean in practice, and what factors affect actual throughput?

The 500 L/h figure refers to the approximate maximum feed volume the screw press can process per hour under typical operating conditions. Actual throughput depends on inlet material properties (solids concentration, particle size, and temperature), any pre-processing (chopping or pulping), and operator settings. Coarser or dryer feed, heavy contamination, or insufficient pre-processing will lower throughput; well-prepared, pumpable slurries will reach or approach the rated 500 L/h.

How do I install and operate the machine safely in my facility?

The unit is usually floor-mounted and should be placed on a level, load-bearing surface with enough clearance for feeding, discharge and maintenance. Connect the electrical supply and grounding per the product datasheet and local codes (confirm single-phase or three-phase requirements with the supplier). Provide a suitable feed pump or hopper as recommended. Operate with guards in place, follow lockout/tagout procedures for maintenance, and ensure operators are trained in safe handling of hot or acidic feeds if applicable. For food applications, use only food-grade detergents and sanitizers during cleaning.

What cleaning and routine maintenance are required to keep the machine working reliably?

Clean contact parts (screw, basket, feed hopper) after each production run to meet food-safety standards; many units allow partial disassembly for manual cleaning or flush cleaning with warm water and approved detergents. Routine maintenance includes daily visual checks, weekly lubrication of specified bearings, and periodic inspection of the screw, screen, seals and wear parts (monthly or by operating hours). Replace wear components such as screens, seals and scraper blades as needed. Keep a log of maintenance and follow the manufacturer’s maintenance schedule.

What level of dryness can I expect from the dewatered cake and what happens to the liquid fraction?

Typical moisture content of the pressed cake varies by feed material but commonly ranges from 30% to 60% moisture (i.e., 40–70% dry solids) depending on the material and press settings. Higher solids feeds and optimal screw pressure produce drier cake. The separated liquid (filtrate) is discharged separately and can be recycled into the plant’s wastewater stream, sent to a treatment system, or reclaimed where permitted (e.g., for rinsing or further processing), subject to local regulations and the nature of the liquid.

What does the 1-year warranty cover, and what should I do if I encounter a problem?

The one-year warranty typically covers defects in materials and workmanship under normal use. It usually excludes normal wear items (screens, seals, blades), damage from misuse, improper installation, unauthorized modifications, or lack of routine maintenance. If you encounter a problem, stop using the machine, document the issue (photos and description), and contact your supplier or manufacturer service department with the serial number and purchase information. They will advise troubleshooting steps, warranty eligibility, and provide replacement parts or service if covered.
