Dynamic aerobic fermentation machine

With the explosive growth of population, people's demand for livestock products is also increasing day by day. As a result, the livestock industry has experienced sustained and rapid development, and has become increasingly large-scale, centralized, and industrialized. However, the high density of livestock has greatly exceeded the processing and use capacity of its surrounding environment, causing pollution to the environment and forming public hazards. Composting is considered an effective means of resource utilization, harmlessness, and reduction of organic solid waste. Composting is a biochemical process that utilizes microorganisms widely present in nature to promote the conversion of biodegradable organic matter into stable humus through human regulation and control. The commonly referred to compost is high-temperature aerobic compost, which uses high temperature to kill bacteria and weed seeds in the pile and obtain organic fertilizer.

Dynamic aerobic fermentation machineIt is an integrated complete set of equipment for processing organic waste such as livestock manure. The process principle is to mix livestock and poultry manure with auxiliary materials and high-temperature biological fermentation bacteria, and use the activity of microorganisms to biodegrade and mature the organic matter in the waste, so as to convert the organic waste into organic fertilizer raw materials for soil improvement and landscaping, and achieve the resource utilization of organic waste. The high-temperature aerobic fermentation equipment includes a mixing section, a high-temperature aerobic fermentation section, and a discharge section,Dynamic aerobic fermentation machineThe animal manure inside is discharged through the discharge door after high-temperature aerobic fermentation.

Aerobic composting is the process in which aerobic bacteria absorb, oxidize, and decompose waste under aerobic conditions. Microorganisms, through their own life activities, oxidize a portion of the absorbed organic matter into simple inorganic substances, while releasing the energy needed for microbial growth activities. Meanwhile, another portion of the organic matter is synthesized into new cytoplasm, enabling microorganisms to continuously grow and reproduce, producing more organisms. Along with the biochemical degradation of organic matter, heat is generated. As this heat energy is not completely dissipated into the environment during the composting process, it inevitably causes an increase in the temperature of the compost material. This can lead to the death of some microorganisms that are not resistant to high temperatures and the rapid proliferation of bacteria that are resistant to high temperatures. Ecological dynamics indicate that the thermophilic bacterial community, which is large in size and active in performance, plays a major role in aerobic decomposition. This microbial community oxidizes and decomposes organic matter in the presence of a large number of oxygen molecules, while releasing a large amount of energy. According to this, the aerobic composting process should be accompanied by two heating stages, which can be divided into three stages: the initial stage, the high-temperature stage, and the maturation stage. The influencing factors of composting process include: volatile solids, ventilation and oxygen supply, moisture, temperature, carbon nitrogen ratio, etc. Usually, it goes through material pretreatment, primary fermentation, secondary fermentation, and post-treatment processes.
