The important processing technology of organic fertilizer production line
is the fermentation technology of organic fertilizer and the deep processing of later stage. The construction of these two points is the key to the success of fertilizer production.
1. Fermentation process
The fermentation process should be based on the amount of materials. Currently, aerobic fermentation is more in line with the national production standards. The fermentation cycle consists of two parts: fermentation maturity and secondary aging. In order to reach the standard, tank fermentation or strip fermentation should be selected as far as possible. Compared with the two, with the same production capacity requirements, strip fermentation occupies more plant area. Another factor affecting the fermentation process is the fermentation equipment used. In tank fermentation, the mobile crane is often used for multi trough fermentation, and the material is directly moved to the outlet in the process of turning and throwing. The second aging stage can be transferred to the fermentation tank, so that continuous fermentation can be realized,; However, it is inconvenient to transfer the raw materials due to walking composter or compost turning machine. The secondary aging process is often in situ aging, which affects the fermentation cycle.
2. Process of late deep processing stage
The equipment post-processing technology of organic fertilizer production line is divided into powder organic fertilizer production line process and granular organic fertilizer production line process. There are great differences between the two processes in terms of occupation area and organic fertilizer production machine
Starting from the powdery organic fertilizer production line technology, the powder organic fertilizer processing technology is that after the raw materials are fermented and decomposed, the main equipment can be sold as long as the grinding, mixing, packaging and other processes. To put it bluntly, the powdery organic fertilizer production line process is one part of the granule processing technology. In terms of granular organic fertilizer production line process, besides crushing, mixing, packaging and other processes, drying, granulation, particle grading and particle coating are also needed. Therefore, granule processing technology is often selected for processing production lines with an annual output of more than 10000 tons, while small capacity enterprises often choose powder fertilizer processing technology.
