Applying organic fertilizer can reduce the use of chemical fertilizers and pesticides, reduce environmental pollution and promote ecological harmony. Economic development has accelerated the process of urbanization. The urban population has increased rapidly, and the urban pollutants and wastes are also increasing. Organic waste contains a large number of bacteria and insect eggs, which will spread bacteria if not treated in time. Organic fertilizer is a slow-release fertilizer generated after a large number of animal and plant residues, excrement, biological waste and other wastes are fully decomposed, which makes the domestic waste return to the ground in another form. Therefore, urban pollutants can be transformed into organic fertilizer through classified treatment, turning waste into treasure, and reducing environmental pollution through rational use of these organic fertilizers, It can also reduce the investment of chemical fertilizer, alleviate the increasingly serious energy crisis, promote safe and clean production of agricultural products from the source, protect the ecological environment and kill two birds with one stone. The development of organic fertilizer equipment is faster and faster. Especially in recent years, in view of the prominent problems in China's agricultural production, such as excessive use of chemical fertilizer, low efficiency and decline in the quality of cultivated land, the main goal of bio organic fertilizer production equipment is to reduce the use of chemical fertilizer, improve the quality of cultivated land and realize the industrialization of new high-efficiency biological fertilizer.

Features of this small household organic fertilizer processing equipment: the machine has reasonable structure design, advanced technology, short fermentation cycle, low energy consumption and stable product quality. The thickness of fermentation materials in the tank is 70-90 cm. During the turning over, the natural ventilation and oxygen provided by the contact between materials and air are used for continuous aerobic fermentation, and the full-automatic intelligent control is realized in the turning over process.
