Fermentation Composting Machine Process for Organic Fertilizer Raw Materials
2023/04/06
In the early 1990s, China introduced foreign tank fermentation technology from foreign countries. On the basis of integrating various treatment methods, combined with the characteristics of China's agricultural and animal husbandry business model, it adopted a comprehensive treatment of solar aerobic fermentation technology.
From the perspective of practicality and cost control, the trough fermentation system is the preferred process for organic fertilizer production line. Here we make a comparison and find that the self-propelled compost turning machine is flexible but has a large area; the fermentation cycle of the fermentation tank is short, but the cost is not suitable for popular demand. At present, the more widely used are the groove type compost turning machine, and the high-grade ones include the double-spiral stacker and the chain plate stacker, etc. There are many types of products, which can be ordered according to their own needs.
The use of solar energy for aerobic fermentation is a very important part of the organic fertilizer production line. During this period, the treatment of organic solid waste must solve the problems of drying, fermentation, sterilization, deodorization, etc., and finally obtain higher economic benefits at a lower cost. Before fermentation, various raw materials to be fermented are mixed in a certain proportion to meet the fermentation conditions such as moisture and carbon-nitrogen ratio, and the purpose of shortening the fermentation cycle is finally achieved to achieve the optimal fermentation effect.
In order to make organic solid waste into efficient organic fertilizer, it must be fully fermented and matured. The application of organic solid waste without fermentation or incomplete fermentation to the land is extremely harmful to crops. It can decompose in the soil to generate heat and carbon dioxide gas and other harmful substances, which seriously affects crop germination and crop root growth. The organic solid waste can achieve the purpose of eliminating harmful substances, germs, and reducing odor after full fermentation. At the same time, it occupies less space, increases the humus uniformly, and is more convenient to use when fertilizing. Fully fermented and decomposed is a necessary process to increase the effective ingredient humic acid in organic fertilizers. Organic raw materials made from organic fertilizers directly added to inorganic fertilizers without being processed in this step are organic-inorganic compound fertilizers. Low phytic acid is not good for crops and soil.
