Cow Dung Rotary Dryer

Large-scale cattle breeding produces massive cow dung every day. Fresh cow dung features high water content, strong viscosity, peculiar smell and rich organic matter. Direct stacking disposal will cause soil pollution, bacterial breeding and odor diffusion, seriously affecting the ecological environment of breeding farms. Meanwhile, untreated wet cow dung cannot be stored or transported, resulting in huge waste of organic resources.

Traditional drying equipment cannot adapt to sticky cow dung materials, prone to serious wall sticking, material agglomeration, incomplete drying and strong odor overflow. Our professional Cow Dung Rotary Dryer is specially optimized for livestock manure characteristics. The customized anti-stick structure avoids material adhesion, and the gradient low-temperature drying process removes moisture while decomposing peculiar odor. The dried cow dung has loose texture, no odor, no live bacteria, and can be directly used as high-quality raw material for organic fertilizer, breeding bedding and soil improvement, bringing considerable economic benefits and environmental value to breeding enterprises.

The main rotary drum adopts an upgraded multi-stage lifting plate structure exclusive for cow dung. The special curved anti-stick design continuously lifts, scatters and flips sticky manure materials during rotation, thoroughly solving wall sticking, accumulation and caking problems. The multi-pass layered drying structure forms a uniform hot air circulation zone inside the drum, eliminating drying dead angles and ensuring full contact between cow dung and hot air for consistent and thorough dehydration.

Fresh cow dung is easy to agglomerate into bulk clusters. The matched pre-breaking feeding device crushes bulk dung blocks in advance and disperses sticky materials. Equipped with variable-frequency quantitative feeding function, it realizes stable and uniform feeding, avoids material accumulation and intermittent blanking, and provides stable operating conditions for continuous and efficient drying.

Exclusive three-stage drying process for cow dung: low-temperature pre-dehumidification to remove surface moisture and reduce odor volatility; medium-temperature uniform dehydration to evaporate internal bound water; constant-temperature sterilization and deodorization to eliminate peculiar smell and harmful bacteria. The whole process avoids high-temperature burning and secondary odor generation, ensuring the finished cow dung is odor-free, sterile and loose.

Equipped with professional waste heat circulation recovery device, which recycles exhaust hot air for secondary heating, reducing comprehensive energy consumption by more than 50%. The supporting dust removal and deodorization purification system effectively filters fine dung powder and decomposes residual odor. The tail gas is discharged up to standard, realizing zero pollution and clean environmental protection production.

Presets exclusive parameter models for cow dung drying. The system automatically adjusts drum rotating speed, hot air temperature and air volume according to material moisture and output requirements. It has over-temperature protection, overload alarm and fault self-diagnosis functions, supporting 24-hour unmanned continuous operation, stable output and consistent finished product quality.

Aiming at the high viscosity of fresh cow dung, the customized curved lifting and scattering structure fundamentally solves the common problems of wall sticking, material accumulation and blockage in traditional dryers. No frequent shutdown cleaning is required, and the continuous operation efficiency is greatly improved, fully adapting to long-term batch drying of livestock manure.

Different from high-temperature drying that easily produces burnt odor, the gradient mild drying process realizes low-temperature dehydration and synchronous deodorization and sterilization. It effectively eliminates pungent odor and harmful bacteria in cow dung. The finished product is odor-free, loose and uniform, meeting agricultural organic fertilizer safety standards.

Equipped with waste heat recovery circulation system and multi-layer heat preservation structure, the energy saving rate is more than 50% higher than ordinary manure dryers. It supports multiple clean heat sources such as biomass, natural gas and steam, with low power consumption and fuel consumption. The equipment has few wearing parts and low failure rate, greatly reducing long-term operating costs.

The dried cow dung retains rich organic matter, nitrogen, phosphorus and potassium elements. It can be directly used for organic fertilizer processing, farmland soil improvement, breeding bedding and edible fungus cultivation. It turns breeding waste into high-value recycled products, realizing circular economy and increasing additional income for enterprises.

The whole machine adopts fully sealed micro-negative pressure operation, effectively preventing fine dung powder and odor overflow. Matched with tail gas purification equipment, no secondary pollution is generated during production. It solves the environmental pollution problem of breeding farms and meets global agricultural environmental protection emission standards.

Integrated automatic feeding, drying, deodorization and discharging process. The intelligent PLC system realizes 24-hour unmanned continuous operation with simple operation and low labor cost. The equipment has compact structure and small floor space, suitable for large-scale centralized manure recycling treatment of modern breeding bases.

The Cow Dung Rotary Dryer adopts gradient low-temperature deodorizing drying + anti-stick dispersion principle. Fresh high-viscosity cow dung is sent to the pre-breaking system to crush bulk agglomerations and disperse sticky materials for uniform feeding.

Materials enter the rotary drying drum stably. With the rotation of the drum, the special anti-stick lifting plates continuously lift, flip and scatter the cow dung to avoid wall sticking and caking. Through three-stage gradient low-temperature hot air circulation, the dung completes surface dehumidification, deep dehydration and deodorization sterilization in turn. The moisture is evaporated and discharged, and the dried odor-free loose cow dung is discharged stably, realizing harmless treatment and high-value recycling of livestock waste.

Q1: Why is professional cow dung dryer different from ordinary rotary dryers?

A: Ordinary dryers have no anti-stick structure, which is easy to cause cow dung wall sticking, caking and incomplete drying, and will produce pungent burnt odor. Our dryer is tailor-made for sticky manure, with exclusive anti-stick design and low-temperature deodorization process, specially for livestock waste recycling.

Q2: Can this dryer completely remove cow dung odor and bacteria?

A: Yes. The gradient low-temperature drying process matches synchronous deodorization and high-temperature sterilization technology, which effectively decomposes peculiar odor and kills harmful bacteria. The finished cow dung is odor-free, sterile and loose, reaching agricultural organic fertilizer safety standards.

Q3: What is the standard moisture of dried cow dung for fertilizer use?

A: The international commercial standard for dried cow dung organic fertilizer is 10%-15% moisture. This moisture range prevents mildew and secondary fermentation during storage and transportation, ensuring long-term stable preservation of organic fertilizer.

Q4: Is the equipment energy-saving for long-term large-scale production?

A: Absolutely. Equipped with waste heat recovery system and multi-layer heat preservation structure, the energy saving rate is over 50% higher than traditional equipment.
