As the global environmental protection awareness increases, efficient and environmentally friendly waste treatment technology is becoming the focus of the industry. With its innovative design and excellent performance, Bolong high temperature aerobic fermentation tank provides a reliable solution for the resource utilization of organic waste.
Bolong high-temperature aerobic fermentation tank is designed for the efficient treatment of a variety of organic wastes, applicable to the harmless treatment of livestock and poultry manure, animal carcasses, food waste, domestic sewage sludge and crop residues. The equipment can directly treat organic waste with moisture content lower than 70%, only need to add specific bacteria in the first run, and after that without any auxiliary materials can directly put organic waste into the tank.
Bolong fermentation tank adopts vertical closed tank structure, which effectively reduces the floor space. For example, the largest model of Bolong fermentation tank 280 (which is also the largest capacity fermentation tank on the market) occupies an area of no more than 66 square meters.
The tank part adopts double-layer tank insulation structure, the inner wall is made of 304 stainless steel, and the outer wall is supported by thickened steel plate, and the center is filled with polyurethane foam of 55mm thickness. This kind of insulation material is not only non-absorbent and not easy to aging, but also has excellent heat preservation effect. The double-layer insulation design enables the equipment to adapt to a variety of environmental conditions, such as high humidity and high temperature, thus ensuring the service life of the fermentation tank.
The equipment operates on a continuous mode of processing, with daily waste placement and continuous production of organic fertilizer. The waste is transported and automatically fed into the tank by means of a bucket elevator, using the hydraulic lifting principle, patented by Bolong, to minimize losses and increase efficiency.
The mixing blades mix the materials in the tank, and the stirring fins with diamond shape and 30° inclined mounting angle is also a patent of our company, which can effectively reduce the stirring resistance and prolong the service life.
Through the specially designed heat exchanger, the heat in the exhaust gas is recovered and used to heat the fresh air, and the warm air is then blown into the tank through the holes of the blades to accelerate the aerobic fermentation of the waste and evaporation of water. In as little as seven days, the waste can be converted into high-quality organic fertilizer for efficient and environmentally friendly reuse of resources.
High-temperature aerobic fermentation tank adopts the principle of aerobic microorganism fermentation, by providing suitable temperature, humidity and sufficient oxygen for aerobic microorganisms, so that they can multiply rapidly and decompose organic matter efficiently.
Aerobic microorganisms take organic matter and residual protein in livestock and poultry manure as the main nutrients, which are decomposed and transformed into carbon dioxide (CO₂), water vapor (H₂O) and ammonia (NH₃) through metabolism. This process releases a large amount of heat energy, causing the temperature inside the tank to rise rapidly, thus providing continuous power for the fermentation reaction.
Through the metabolism of microorganisms, nitrogen, phosphorus and potassium in the organic matter are converted into compounds in the active state that can be directly absorbed by plants. In addition, humus is synthesized during the fermentation process, which is a kind of polymer organic compound that not only significantly enhances soil fertility, but also improves the physical structure and water and fertilizer retention properties of the soil.
After the fermentation is initiated, the blower promotes the proliferation of microorganisms by precisely controlling the oxygen supply. Within 2 days, the material enters the high-temperature phase, when the temperature rises rapidly to 50℃-80℃, and maintains this temperature range for 5-7 days under the regulation of the automated control system.
The high temperature phase not only significantly improves the decomposition efficiency of organic matter, but also effectively kills pathogenic bacteria, parasite eggs and weed seeds, so that the fermented material reaches the standard of harmlessness and stabilization. The whole fermentation cycle usually lasts for 7 days, and the homogeneous mixing of the fermented materials through the stirring fins further improves the homogeneity and quality of the organic fertilizer.
In order to further optimize the fermentation process, the equipment is equipped with an independent deodorization unit, which is capable of centrally collecting and treating the odorous gases generated during the fermentation process. Deodorization is carried out through a water spraying system to ensure fresh air in the plant and the surrounding environment. At present, the latest gas deodorization system 5.0 developed by Bolong has been innovatively modified on the basis of the original, and the deodorization effect can reach over 90%.
From the highly efficient continuous processing mode to the intelligent temperature-controlled deodorization design, Bolong fermentation tank perfectly combines environmental protection and innovation to create higher value for the users and at the same time contributes to the global ecological protection. If you are looking for an efficient and reliable solution for organic waste treatment, Bolong fermentation tank is undoubtedly your best choice. Welcome to contact us!
