As living standards rise, so does the demand for a healthy lifestyle, fueling the rapid development of modern biotechnology. Among its essential components, the fermentation tank plays a crucial role, directly providing the necessary enzymes, amino acids, organic acids, and other organic substances for modern biotechnology. During fermentation, microbes in the tank require stirring to mix air with the fermentation liquid, allowing oxygen to dissolve and support microbial growth and reproduction.
With the development of modern agriculture, the issue of rural environmental pollution has become increasingly prominent, and its危害 has surpassed industrial pollution, necessitating urgent systematic treatment.

Organic matter is the material basis for the production of life, and all living organisms contain organic compounds. Metabolism within biological organisms and the phenomenon of heredity involve transformations of organic compounds. Organic matter can be fermented into organic fertilizer, a carbon-rich material primarily used to provide plant nutrition when applied to soil. Processed from biomass, animal and plant waste, and plant residues, it eliminates toxic and harmful substances, and is rich in beneficial components, including various organic acids, peptides, and a wealth of nutrients such as nitrogen, phosphorus, and potassium. Not only does it supply nutrients to crops, but it also has long-lasting fertilizer effects, enhances and updates soil organic matter, promotes the proliferation of microorganisms, improves the physical and chemical properties of soil, and enhances its biological activity, making it a major nutrient for the production of green food.

China's livestock and poultry breeding industry has developed rapidly, with many suburban areas establishing large and medium-sized intensive breeding farms. The number of livestock and poultry has surged, enriching the supply of animal products and by-products for urban and rural residents, and improving their living standards. At the same time, the production of livestock and poultry waste is also rapidly increasing. This waste contains a large amount of nitrogen, phosphorus, suspended solids, pathogenic bacteria, and high concentrations of organic pollutants. Improper disposal can cause serious harm to the atmosphere, water bodies, soil, and ecosystems. To protect and optimize the natural ecological environment and control and eliminate the pollution caused by livestock and poultry waste, an important approach is to treat and recycle the waste in a harmless manner. This helps prevent and eliminate the pollution from breeding farms, protect the natural ecological environment, and promote the sustainable development of agriculture. In the past, even with related treatment measures, the processing level of breeding farms mostly remained at primitive methods such as piling and fermenting waste back into the fields. This outdated composting method has defects such as large volume, strong odor, and unsanitary conditions.

With the development of society, there's an increasing preference for eco-friendly foods. Foods grown with organic fertilizers are gaining popularity due to their abundant raw materials, such as fallen leaves, straw, and organic waste from animals and humans. Compared to chemical fertilizers, organic fertilizers offer higher nutritional value and don't degrade soil quality, causing issues like compaction and poor aeration. Liquid organic fertilizers are a crucial source, easily absorbed by soil and play a significant role in increasing crop yields, making them popular among farmers. However, currently, organic fertilizer fermentation typically occurs in fermentation ponds or tanks, generating a lot of heat during the process. This requires stirring for heat dissipation, often using fermentation pit turning equipment, which is costly and inconvenient. Moreover, the large amount of heat produced during fermentation goes unused, leading to resource waste.
In the livestock industry, the treatment of animal waste has become a significant issue. With large-scale operations requiring the handling of substantial amounts of waste, centralized treatment is generally necessary. However, the waste cannot be disposed of arbitrarily, as this can lead to environmental pollution. Therefore, a compost fermentation unit for the fermentation of animal waste into organic fertilizer compost is used.
