Laser-Cut Volute Filter Press for Food Industry Sludge
Product Description
Features: Hygienic and High-Precision
Laser-Cut Filtration Excellence
Filter plates made via 500W fiber laser cutting, achieving slot accuracy of ±0.05mm—critical for capturing 50μm+ food particles that clog standard screens.
Volute screw with variable-pitch threads (150mm at inlet, 50mm at outlet) increases compression gradually, preventing channeling and ensuring 95% water extraction from dairy sludge.
Food-Grade Compliance
All wetted parts: 316L stainless steel (passivated to reduce surface roughness), certified by NSF/ANSI 61 for drinking water contact and EU 10/2011 for food contact.
Surface finish: Ra ≤ 0.8μm (mirror-like), making it easy to clean and resistant to biofilm formation—essential for audits by companies like Nestlé and AB InBev.
Efficient for Organic Sludges
Processes 10m³/h of sludge, producing cake with 45% solids content (dairy sludge) to 50% (brewery spent grains)—ideal for anaerobic digesters requiring high-solid feedstock.
Low noise operation (≤75dB), achieved through sound-insulated housing and precision-balanced screw—safe for plants located near residential areas (e.g., urban breweries in Portland, OR).
Applications: Food Industry Specialized
Dairy Processing: Handles whey permeate sludge (high lactose), cheese brine waste, and milk solids from pasteurization—proven in Dean Foods and Danone facilities.
Beverage Plants: Dewaters spent grains (beer production), fruit pulps (juice concentrate), and yeast residues (wine making), reducing disposal costs by 40%.
Meat & Poultry: Processes blood plasma, rendered fat, and protein slurry from deboning lines—output cake is suitable for pet food production (with 40%+ solids).
Why Choose Our Laser-Cut Press?
Hygiene First: The only press in its class with both FDA and BRCGS certifications—critical for export to markets with strict food safety laws.
Precision Engineering: Laser-cut components fit together with 0.1mm tolerance, reducing leaks by 90% compared to conventionally manufactured presses (common issue with sticky food sludges).
Zero Waste Promise: Our team helps you develop byproduct recovery plans—for example, turning potato processing sludge into fertilizer pellets sold at $80/ton.
Overall Structure
Component Display
The main body of volute sludge dewatering is made of multiple fixed ring and moveable ring with the screw shaft running through it. The front part is concentrating section and the ending part is dewatering section. It can concentrate and dewater sludge in one box and has taken place of the traditional filter clothes and centrifugal filtration method for its distinctive filter model.
Working Principle
Sludge will be transported to the dewatering part after being thickened in the concentrating section. In the advancing process, great pressure has been produced because of the gradually decreasing filter spacing and screw distance with the block of the back platen. Then the volume decreases continuously, and the purpose of fully dewatering will be achieved.
Function
Innovative structure design makes it possible that the device can be used for all kinds of sludge with high or low density, especially the sludge with oil, and it can be named the invincible opponent to dewater the sludge with oil.
