Food Waste Fermentation Machine

Product Overview

The food waste fermentation machine is a closed-type, high-speed aerobic fermentation device specially designed for the treatment of kitchen organic waste. It integrates a heating jacket, stirring blades, liquid microbial inoculation spraying, air supply and exhaust purification, and a PLC control system into one unit. It can complete the high-temperature sterilization and fermentation of kitchen organic waste within 4–24 hours, ultimately producing high-quality bio-organic fertilizer, thereby achieving closed-loop, harmless, and resource-oriented disposal of organic waste and effectively addressing many pain points associated with traditional organic waste treatment methods.

Equipment Composition

The entire machine consists of several core systems, including the fermentation main unit, liquid microbial inoculation spraying system, air supply system, exhaust air purification system, feed and discharge system (optional), and control system. Among these, the fermentation main unit is the core component, comprising transmission parts, multi-angle stirring blades, a U-shaped vessel with a heating jacket, a multifunctional vessel lid, and a bottom discharge valve. The control system supports both fully automatic program operation and manual mode, adapting to different operational needs. The air purifier is an optional module that effectively treats exhaust gases such as ammonia and hydrogen sulfide generated during fermentation, preventing odor diffusion.

Technical Principle

After pre-processing, the kitchen organic waste is fed into the U-shaped vessel equipped with a heating jacket. The transmission system drives the main shaft via a hardened gear reducer, which in turn rotates the multi-angle stirring blades to continuously turn over the material, ensuring thorough and uniform mixing. The heating jacket works in conjunction with the system to precisely regulate the material temperature, while the equipment also monitors internal temperature, humidity, and pH levels in real time, providing an optimal environment for fermentation. The liquid microbial inoculation spraying system periodically pumps in fermentation agents, and the air supply system continuously introduces fresh air, maintaining a stable aerobic fermentation environment and fundamentally preventing the unpleasant odors associated with anaerobic fermentation. In this sealed environment, the equipment can achieve high-temperature sterilization and pest control, completely eliminating harmful microorganisms and insect eggs in the kitchen waste, completing the harmless fermentation process within 4–24 hours. Gases produced during fermentation, such as ammonia, hydrogen sulfide, and water vapor, are drawn by an induced draft fan into the optional air purifier for purification and recovery, thus avoiding environmental pollution. Once fermentation is complete, the material is discharged through the bottom discharge valve, yielding high-quality bio-organic fertilizer. The discharge valve supports manual, mechanical, and electric control modes, allowing the entire system to operate either fully automatically according to preset programs or switch to manual mode as needed, flexibly adapting to various scenarios.
