How Does The Organic Fertilizer Fermentation Tank Work?

organic fertilizer fermentation tank

Introduction to organic fertilizer fermentation tank

An organic fertilizer fermentation tank is a specialized container or vessel designed for the controlled decomposition and fermentation of organic materials, such as agricultural waste, manure, and plant residues. This process converts organic matter into nutrient-rich, environmentally friendly organic fertilizer. Within the fermentation tank, a combination of microorganisms, moisture, and oxygen levels are carefully managed to facilitate the breakdown of organic matter into valuable compost. This natural and sustainable approach not only reduces waste but also produces a valuable soil conditioner and nutrient source for agriculture and gardening.

Application fields of organic fertilizer fermentation tanks

Organic fertilizer fermentation tanks find application in a wide range of areas, primarily in agriculture and environmental sustainability. Some key areas where these tanks are used include:

Agriculture: Organic fertilizer fermentation tanks are extensively employed in agriculture to convert organic materials like animal manure, crop residues, and kitchen waste into nutrient-rich organic fertilizers. These fertilizers enhance soil quality, improve crop yield, and promote healthier, more sustainable farming practices.

Gardening and Landscaping: Organic fertilizer fermentation is popular among gardeners and landscapers for enriching soil in home gardens, flower beds, and landscaping projects. It provides a natural and chemical-free way to nourish plants, resulting in lush, vibrant greenery.

Waste Management: In urban and rural areas, organic waste management is a growing concern. Fermentation tanks are used to efficiently process and recycle organic waste, reducing landfill usage and mitigating the environmental impact of waste disposal.

Composting Facilities: Commercial composting facilities utilize large-scale fermentation tanks to process significant volumes of organic waste, which can include municipal green waste, food scraps, and more. This helps divert organic material from landfills and reduce methane emissions.

Organic Fertilizer Fermentation Tanks Operating Principle

The organic waste harmless treatment equipment is suitable for the treatment of different feces, livestock, and poultry carcasses. kitchen waste, and domestic sewage sludge. As long as the water content of organic waste is below 70%, no auxiliary materials need to be added and can be put into the tank directly. The equipment can adapt to different regions with high humidity and high cold and adopts a vertical closed tank structure, which reduces the installation area. The equipment adopts the aerobic fermentation principle of aerobic microorganisms so that the microorganisms use the organic matter and residual protein in livestock and poultry manure and kitchen waste to rapidly multiply under a certain temperature, humidity, and sufficient oxygen environment, thereby realizing the organic waste harmless treatment.

The organic fertilizer fermentation tank controls the temperature between 65-75°C through ventilation, oxygenation, stirring, etc. to reach the temperature for material fermentation. At this temperature, a large number of pathogenic bacteria and parasites in the pile can be killed, and at the same time, utilization The deodorization system carries out biological odor on the discharged gas to achieve the purpose of harmless treatment.

This equipment can process organic waste such as animal waste, bacterial residue, traditional Chinese medicine residue, crop straw, etc. It is simple to operate and occupies a small area. The work is not affected by the outside temperature. The fermentation speed is fast, there is no peculiar smell, no polluting gas is produced, and the harmless treatment process can be completed in a short time. Compared with traditional aerobic compost fermentation, it saves a lot of time and is a powerful tool to increase production.

By adjusting the moisture, oxygen content, and temperature changes of the raw materials, the materials can be fully aerobically fermented and decomposed. The heat released during the decomposition process can increase the temperature of the material itself, which can reach 95°C. The moisture in the fermentation material increases as the temperature increases. As it rises and evaporates, some of the organic matter is broken down, reducing the size of the pile and achieving waste reduction.

It is a continuous system where waste is thrown out every day and organic fertilizer is produced every day. The bucket elevator lifts the organic waste and puts it into the tank automatically. The organic waste is mixed in the tank by stirring blades. A special heat exchanger uses the heat of the exhaust gas to heat the fresh air and let it enter the tank. The hot air is blown out through the holes in the blades. Warm air accelerates the aerobic fermentation of organic waste and the evaporation of water. After an average of 7 days, organic waste is converted into high-quality organic fertilizer.

Organic fertilizer fermentation tank components

The whole equipment structure is divided into three parts. The lower part of the base is distributed with hydraulic stations, scroll pumps, oil cylinders, heating systems, and mixing shafts. the middle part is a double-layer heat insulation tank, equipment automatic control system, export device, etc. The wall is lined with 304 stainless steel plates, which can effectively extend the life of the tank and reduce the residue of rot clinker. there is a thermal insulation layer filled with polyurethane foaming agent in the middle. The outer wall is made of a thick steel plate to support the tank; The upper part is composed of a wind and rain shed, detection platform, and exhaust facilities. Ancillary equipment includes an automatic tipping hoist, exhaust gas deodorization system, and heat exchange system.

Design advantages of organic fertilizer fermentation tanks

An organic fertilizer fermentation tank is a processing method for high-quality organic fertilizer, which has the characteristics of less taste, environmental protection, and energy saving. Traditional fermentation methods cannot meet the needs of fermentation, nor can they meet the needs of energy conservation and emission reduction. The organic fertilizer fermentation tank overcomes the shortcomings of traditional fermentation tank fermentation processes, floor space, and capital allocation, and improves productivity.

  • Closed Fermenter: The tank is fully enclosed, meeting industrial production standards, preventing gas leakage, and eliminating secondary pollution.
  • Thermal insulation treatment: The tank uses polyurethane insulation, ensuring year-round fermentation, regardless of external conditions.
  • Energy Efficiency: A patented heat exchange system circulates hot air, reducing energy consumption and improving efficiency.
  • Electrical control: lt adopts the control system of PLC chip with a combination of automatic and manual control, which is convenient for operation control.
  • Space-Saving: Its vertical closed tank design saves floor space and allows outdoor installation without the need for a factory building.
