What is Kitchen Waste Screw Dehydrator?
Kitchen waste is characterized by ultra-high moisture, mixed grease, vegetable fibers, food residues and easy winding impurities. Untreated kitchen waste occupies large space, produces foul odor, breeds bacteria, and brings high transportation and disposal costs for environmental protection projects. Traditional manual dehydration and simple filtering equipment have low separation efficiency, easy blockage and serious material leakage, which cannot meet industrial continuous treatment needs.
Our Kitchen Waste Screw Dehydrator adopts advanced mechanical screw extrusion principle. Through gradual pressure increase and precise gap control, it efficiently separates free water, grease and organic sludge from kitchen waste. The fully sealed structure prevents odor overflow, and the anti-winding screw design ensures stable continuous operation. As the core pretreatment equipment of kitchen waste recycling system, it greatly reduces subsequent processing pressure and improves overall project benefit.

Complete Equipment Composition of Kitchen Waste Screw Dehydrator
1. Anti-Winding Variable-Pitch Screw Shaft (Core)
The core screw shaft adopts optimized variable-diameter and variable-pitch structure. The pitch gradually decreases from feeding end to discharging end, forming gradual extrusion pressure, which fully squeezes internal moisture and grease of kitchen waste. The special non-winding blade design effectively avoids fiber and vegetable residue entanglement, completely solving the common blockage failure of traditional screw presses. The surface is treated with wear-resistant and anti-corrosion process, with long service life and stable extrusion performance.
2. High-Precision Stainless Steel Filter Screen Barrel
The filter barrel is made of thick 304 stainless steel, with uniform and dense filter holes. It can effectively intercept solid organic materials while smoothly discharging sewage and waste oil, ensuring high separation precision. The integrated screen structure is not easy to deform or damage under long-term high-pressure extrusion, and is resistant to oil corrosion and material abrasion, adapting to long-term high-load industrial operation.
3. Fully Sealed Anti-Odor Housing System
The whole machine adopts fully closed structural design with micro-negative pressure operation, which effectively locks peculiar smell and prevents odor overflow during dehydration process. It avoids secondary air pollution in the workshop, meeting urban environmental protection production standards. The detachable sealed cover is convenient for daily cleaning and maintenance without dead corners.
4. Automatic Feeding & Discharging Adjustment Device
Equipped with quantitative feeding and adjustable discharging baffle mechanism. The extrusion pressure can be automatically adjusted according to different waste moisture and material properties, ensuring stable and uniform dehydration effect. It supports continuous feeding and uninterrupted discharging, realizing fully automated assembly line operation without manual intervention.
5. Low-Noise Energy-Saving Drive & PLC Control System
Adopts high-torque low-speed drive motor, with strong extrusion force, low noise and low power consumption. Matching intelligent PLC control panel, it supports one-key start-stop, automatic fault alarm and overload protection. The system can intelligently adjust operating parameters according to material volume, ensuring safe, stable and energy-saving operation of the equipment.

The equipment features simple structure, few wearing parts and convenient daily cleaning and maintenance, reducing labor operation cost.
6. Wide Material Adaptability
This screw dehydrator is not only suitable for all kinds of kitchen and catering waste, but also compatible with fruit and vegetable residues, food processing dregs, wet organic garbage and other high-moisture organic materials. It has strong versatility and can match multiple waste pretreatment scenarios.
Working Principle & Production Process of Kitchen Waste Screw Dehydrator
Working Principle
The Kitchen Waste Screw Dehydrator adopts physical screw extrusion solid-liquid separation principle. After crushed and homogenized kitchen waste enters the extrusion bin, the variable-pitch screw shaft pushes materials forward continuously. With the gradual reduction of screw pitch and extrusion gap, the internal pressure increases steadily, squeezing free water, waste oil and organic sewage out of materials.
Liquid impurities flow out through the precision filter screen and are collected centrally, while solid materials are retained and continuously extruded and dehydrated. Finally, dry low-moisture kitchen waste is discharged from the adjustable discharging port. The whole process realizes automatic feeding, continuous extrusion, efficient separation and stable discharging, completing high-standard pretreatment of kitchen waste in one step.
Standard Working Flow
Raw Kitchen Waste Feeding → Homogenization & Pre-Crushing → Screw Continuous Extrusion → Solid-Liquid Separation → Sewage & Grease Collection → Dry Material Discharging → Subsequent Drying / Composting / Resource Recycling
