Tower fermentation tank
- High efficiency and energy saving: Organic fertilizer tower fermentation tanks usually adopt a multi-layer structure. The material flows from top to bottom in the tank, forming a countercurrent contact with the air, so that the oxygen utilization in the fermentation process is more sufficient, the fermentation efficiency is high, and it can also effectively reduce energy consumption.
- The organic fertilizer tower fermentation tank has a high degree of automation: equipped with an advanced control system, it can achieve precise control and real-time monitoring of parameters such as temperature, humidity, ventilation volume, etc. during the fermentation process, reduce manual intervention, reduce labor intensity, and improve production efficiency and product quality stability.
- Small footprint: The tower structure design of the organic fertilizer tower fermentation tank greatly reduces the footprint compared to tank fermentation tanks under the same production scale, which is especially suitable for areas with limited land resources.
- Good environmental performance: The fermentation process of the organic fertilizer tower fermenter is carried out in a closed tank, which can effectively prevent the spread of odor and contamination by bacteria, reduce the impact on the surrounding environment, and is also conducive to the centralized treatment of waste gas generated by fermentation to meet environmental emission requirements.
- Excellent product quality: The organic fertilizer tower fermentation tank precisely controls the fermentation conditions so that the materials can be in the best environment at different fermentation stages, which is conducive to the growth and metabolism of microorganisms. The organic fertilizer products produced are of stable quality, high nutrient content and good degree of maturity.
Structural design of organic fertilizer tower fermentation tank
- Tank material: The part in contact with the material is usually made of 304 stainless steel, which has good corrosion resistance, can extend the service life of the tank and prevent the material from being contaminated.
- Insulation design: The inside of the tank is equipped with an insulation layer such as polyurethane or rock wool to reduce heat loss, keep the temperature inside the tank stable, and not be affected by the external environment, ensuring normal fermentation all year round.
- Multi-layer structure: generally a tower-type multi-layer structure, such as a six-layer fermentation room, including a feeding layer, a preheating layer, a heating layer, a high-temperature layer, a cooling layer, and a clinker layer. Different layers realize the functions of different fermentation stages.
Working principle of organic fertilizer tower fermentation tank
By delivering oxygen to the materials in the tank and continuously turning the materials under the action of the stirring shaft, the activity of aerobic bacteria is maintained. Microorganisms decompose organic matter to generate heat energy, raising the temperature to 50-65 degrees Celsius. After about 7 days of high-temperature fermentation, insect eggs, pathogens and grass seeds are effectively killed, achieving harmless treatment.
Organic fertilizer tower fermentation tank equipment function
- Stirring function: equipped with a low-speed rotating hollow shaft and hollow stirring blades. The multi-layer blades stir the materials at a uniform speed at the same time, so that the materials are mixed evenly, ensuring uniform fermentation and achieving mature fermentation.
- Ventilation function: The high-pressure vortex air pump acts as a ventilation pump to fully supply the oxygen required for the fermentation process and promote the smooth progress of aerobic fermentation.
- Loading and discharging of organic fertilizer tower fermentation tank: The automatic bucket elevator lifts the fermentation materials into the fermentation tank, and the discharging device can discharge the fermented organic fertilizer out of the fermentation tank, realizing automatic loading and discharging.
- Intelligent control: It adopts a control system that combines PLC computer automatic and manual control, which can monitor and control the temperature, humidity, ventilation volume and other parameters during the fermentation process in real time.
- Waste gas treatment: The waste gas treatment system can absorb and spray the waste gas and dust generated during the fermentation process to avoid environmental pollution.
Technical parameters of organic fertilizer tower fermentation tank
- Processing capacity: The common processing capacity is 5-30 cubic meters. There are also equipment with larger processing capacity, which can be selected according to actual production needs.
- Power: The heating power is generally 24-58 kW, and the stirring power is 7.5-18.5 kW. The power of equipment of different specifications and models will vary.
- Fermentation cycle: Usually about 7 days, which is significantly shorter than traditional fermentation methods.
Application scope of organic fertilizer tower fermentation tank
It is suitable for the treatment of various organic wastes such as livestock and poultry manure such as chicken manure, cattle, sheep and horse manure, agricultural waste such as straw, soybean meal, industrial waste such as wine dregs, vinegar dregs, and domestic waste such as kitchen waste.
