Zhite Integrated Kitchen Waste Crushing and Dewatering Machine

Product Overview

The Zhite Integrated Kitchen Waste Crushing and Dewatering Machine is an all-in-one solid–liquid separation device that combines crushing and pressing–dewatering functions, specifically designed for on-site volume reduction and pre-processing of kitchen waste. The equipment integrates the two core functions—crushing and pressing–dewatering—into a single unit, eliminating the need for multiple separate machines and minimizing space requirements, making it ideal for projects with limited site space. Utilizing a combined process of double-row alloy blades for crushing, a variable-pitch screw paired with a 304 stainless steel screen cylinder for pressing–dewatering, this machine achieves highly efficient solid–liquid separation. The separated liquid phase can be used for biogas production, while the solid phase can undergo composting and fermentation to produce organic fertilizer, truly realizing both volume reduction and resource recovery of kitchen waste, and providing qualified pre-treated materials for subsequent resource‑processing steps.

Technical Principle

As an integrated pre-processing device for kitchen waste, the machine primarily consists of two core modules: the crushing unit and the pressing–dewatering unit. Materials flow continuously within the equipment without requiring transfer between multiple units. After kitchen waste is fed into the machine, it first enters the crushing unit, where double-row alloy blades shear and pulverize large pieces of food waste, breaking down hard materials such as bones and leftover dishes into particles suitable for pressing, ensuring smooth operation of the subsequent pressing stage. The crushed material is then directly conveyed to the pressing–dewatering unit, where a variable-pitch screw continuously applies progressive pressure, efficiently squeezing out moisture and oils from the waste. The liquid passes through a 304 stainless steel screen cylinder, completing solid–liquid separation. The separated liquid can serve as feedstock for biogas fermentation, while the dewatered solids can be transported off-site or processed on-site into compost and organic fertilizer, achieving dual resource recovery of kitchen waste.

Core Advantages

1. Highly Integrated, Compact Footprint: By combining crushing and pressing–dewatering into a single unit, there’s no need for multiple separate machines, significantly saving space—especially suitable for canteens, industrial parks, small sanitation stations, and other settings with limited room, eliminating the need to allocate additional space for installing and transferring multiple devices.

Reliable Pressing–Dewatering Performance: Featuring a variable-pitch screw design paired with a corrosion-resistant 304 stainless steel screen cylinder, this system delivers high dewatering efficiency, thoroughly separating moisture and oils from kitchen waste. Meanwhile, the 304 stainless steel screen exhibits strong rust resistance and long service life, lowering maintenance costs.
4. Dual Resource Recovery: The separated liquid can be used for biogas production, while the solids can be turned into organic fertilizer, providing qualified pre-treated materials for downstream biogas projects and organic fertilizer production lines, ensuring stable and efficient operation of backend processes.
5. Customization Capability: The machine supports tailored design and manufacturing based on specific customer needs, adapting to various scales and material characteristics of kitchen waste treatment scenarios, meeting diverse project requirements.
6. Comprehensive Technical Service Support: Offering end-to-end services—from pre-sales site surveys and equipment selection, to in-sales construction planning, and post-sales installation, commissioning, and hands-on operator training—this support helps customers overcome challenges related to insufficient experience in operating solid-waste equipment, lowers the barrier to entry for equipment use, and ensures rapid, stable deployment.

Core Product Value

1. Volume Reduction and Lower Transportation Costs: Integrating crushing, pressing, and dewatering into one unit dramatically reduces the moisture content and volume of kitchen waste, thereby decreasing the frequency and cost of external collection and transportation, while also preventing secondary pollution caused by leakage along the way.
