Shandong Heze Sanyi Biological Engineering Co., Ltd. is one of the leading manufacturers and suppliers of organic waste aerobic fermentation tank in China. With abundant experience, we are committed to providing high quality equipment made in China with competitive price. Welcome to buy durable organic waste aerobic fermentation tank from our factory. Customized orders are welcome.
Product Overview
The aerobic fermentation tank for organic waste is an integrated vertical sealed complete set of equipment, specially developed for harmless treatment and resource recycling of various organic solid wastes including chicken manure, dry-cleaned pig manure, solid-liquid separation residues, municipal sludge, dead livestock and poultry, kitchen waste, etc. Suitable for high-humidity and temperate conventional areas, it follows the core principle of aerobic microbial fermentation. Raw manure with moisture content ≤75% can be directly fed without auxiliary materials such as straw and wood chips. The tank maintains a high temperature above 65℃ for 7–10days to completely eliminate pathogenic bacteria, parasite eggs and weed seeds in manure. The fully decomposed finished product complies with NY525-2021 Organic Fertilizer National Standard, producing high-quality commercial organic fertilizer and realizing a closed-loop treatment of reduction, harmlessness and resource utilization for breeding and municipal organic waste. With a compact vertical structure, the equipment greatly reduces floor space, and is equipped with complete deodorization, heat exchange, stirring, aeration and discharging units for independent operation.
Core Accessories
Double-layer Insulated Fermentation Tank Body
The inner wall adopts 3mm national standard 304 stainless steel plate, acid and alkali resistant, non-sticky and easy to clean; the outer wall uses ≥3mm national standard 201 stainless steel for structural reinforcement; the interlayer is filled with high-density polyurethane insulation, sealed by full laser welding to lock temperature and reduce heat loss inside the tank.
Stirring Assembly (Main Shaft + Stirring Blades)
The main shaft is made of Q355 high-strength thick-walled seamless steel pipe with high coaxiality and low operation vibration. The stirring frame adopts Q355 high-strength steel for load bearing, and all material contact parts are fully covered with 304 stainless steel. The blades are equipped with thickened reinforcing base plates to avoid deformation under long-term heavy load. The spindle ratchet is integrally forged and quenched-tempered from 42CrMo alloy steel, wear-resistant, fracture-proof and stable in load bearing.
Aeration, Heating & Heat Exchange System
Equipped with vortex aeration fans to continuously supply oxygen for aerobic microbial metabolism. A waste heat recovery heat exchanger recycles fermentation waste heat for circulation, achieving over 30% energy saving under normal working conditions. Electric or steam auxiliary heating modules are optional to stabilize fermentation temperature range.
Multi-stage Deodorization System
Adopts a multi-stage purification process: sealed gas collection → primary spray → pickling → saturated ozonated water oxidation. Fermentation odor is collected centrally, and odor molecules are degraded and decomposed through multi-stage reactions. Exhaust gas is discharged at high altitude up to GB 14554 odor emission standard without secondary pollution.
Feeding & Discharging Mechanism
Support hydraulic lifting feeding hopper and automatic discharging conveyor with centralized lubrication system, automatic start-stop function to cut manual transportation work.
Basic Electric Control Unit
Basic touch operation panel to monitor temperature, humidity, oxygen concentration and running time in real time, with fault alarm and data storage functions to realize basic automatic start-stop regulation.
Process & Core Advantages
- Direct Fermentation Without Auxiliary Materials Different from traditional composting requiring conditioning materials, raw high-moisture manure can be directly fed into the tank, eliminating the cost of purchasing, crushing and mixing auxiliary materials and reducing overall treatment cost.
- Sealed Vertical Fermentation Process The fully closed tank prevents odor leakage. Compared with open strip compost and tank-type fermentation, odor diffusion is controllable. Each unit only occupies 70–105 ㎡, increasing site utilization rate by over 60%.
- High-temperature Sterilization & Decomposition Process Constant temperature of 65–75℃ for 7–10 days thoroughly kills harmful organisms via biological high temperature, realizing uniform decomposition, sufficient organic matter degradation and stable nutrient content of organic fertilizer.
- Multi-stage Exhaust Purification Process Triple deodorization including spray adsorption, acid-base neutralization and deep ozone oxidation thoroughly decomposes ammonia, hydrogen sulfide and other odorous substances, fully complying with environmental protection standards and eliminating peculiar smell in the plant area.
- Comprehensive Equipment Advantages Core tank and stirring parts adopt anti-corrosion stainless steel matched with high-strength structural steel, wear-resistant and durable with low failure rate under long-term heavy load. Modular integrated design enables convenient installation. The fermentation cycle lasts about 15 days, supporting continuous feeding and daily discharging for stable large-scale organic waste treatment.
