Horizontal fermenters are suitable for processing various types of manure, livestock and poultry carcasses, kitchen waste, and domestic sewage sludge.
Horizontal fermenters are widely used in the microbiology laboratories of research institutes and enterprises, and are ideal tools for precision fermentation experiments. They can be used to select culture medium formulations for microbial fermentation, optimise fermentation process parameters, and validate production processes and microbial strains.
I. Structural Composition:
The horizontal fermenter system comprises the fermenter vessel, an air treatment system, a steam purification system, an electrical control system, a temperature control system, piping, valves and auxiliary systems, sensors and instrumentation, a lower-level control system (on-site PLC control system and secondary instrumentation), an upper-level control system, and a test bench.
Provided that the moisture content of the organic waste is below 70%, it can be fed directly into the vessel without the need for any auxiliary materials. This equipment is suitable for various high-humidity and cold regions. It adopts a vertical, enclosed tank structure, thereby reducing the installation footprint. Utilising the principle of aerobic fermentation by aerobic microorganisms, the equipment enables microorganisms to rapidly multiply under specific temperature, humidity and oxygen-rich conditions, utilising organic matter and residual proteins from livestock manure and carcasses to achieve the harmless treatment of livestock and poultry waste.
II. Advantages of the Horizontal Fermenter:
1. High levels of mechanisation and integration ensure optimal space utilisation and a small footprint; a single unit occupies just 50 m², eliminating the need for new factory premises and reducing investment costs;
2. The project features a high degree of automation; a single operator can manage the entire fermentation process, avoiding direct contact between personnel and materials;
3. Utilises high-temperature aerobic fermentation technology with selected microbial strains, relying on microbial activity to degrade and decompose organic matter, resulting in low energy consumption and low operating costs;
4. The main body of the equipment employs an insulation design and is equipped with an auxiliary heating system, enabling normal operation in low-temperature environments and mitigating the impact of ambient temperature on the fermentation process;
5. Equipped with a deodorisation system to collect and treat odours generated during fermentation, ensuring compliance with gas emission standards and preventing secondary pollution of the surrounding environment;
6. The main body of the equipment is constructed from special stainless steel, reducing corrosion and ensuring a long service life;
7. The treated material can be used for soil improvement, landscaping and the production of organic fertilisers, thereby achieving the resource utilisation of organic waste;
This process aligns with the principles of green, eco-friendly household practices, the circular economy and resource utilisation, scientific development, and energy conservation and emission reduction.
III. Working Principle of the Horizontal Fermenter
Firstly, the material to be fermented is fed into the fermentation tank via the inlet. Once all the material is inside, the main motor is started. The motor, via a reduction gearbox, drives the main shaft to begin stirring. The spiral blades on the stirring shaft turn the material over, allowing it to come into contact with air and initiating the aerobic fermentation stage.
Secondly, the heating system at the base of the electric heating rods begins to heat the heat transfer oil in the fermentation tank’s jacket. The temperature of the tank is regulated via temperature sensors, maintaining the fermentation tank at an optimal temperature for the fermentation process. Once the material has fermented, it is discharged from the tank through the discharge port for further processing.
