The specific operation process of organic fertilizer production line

How do small organic fertilizer processing plants process and produce standard, high-quality organic fertilizers suitable for local use?
As a general organic fertilizer production, the steps mainly include crushing, fermentation, granulation, drying, etc., but if you want to meet local needs, you need to add a certain amount of N, P, K and other compound fertilizers, and then mix and stir It is uniform and made into granules by physical extrusion.
The specific operation process of organic fertilizer production line is as follows:
1. Fermentation and decomposing of organic materials: Because the fresh manure of livestock and poultry generally has a large water content, a large amount of auxiliary materials such as straw and shell chaff are often added. During the composting period, organic fertilizer fermentation equipment is used to turn over, promote oxygen, evaporate excess water, Control the internal temperature of the pile so that it will not be too high to cause the inactivation of beneficial bacteria.
2. Material crushing: Since it needs to be left to rot and decompose for about a week in the later stage of fermentation, a large amount of agglomeration will occur, which is not conducive to the later stages of stirring and granulation.
At the same time, in order to meet the fertilizer requirements of local soil and crops, a certain amount of N, P, K and other compound fertilizers need to be added. These compound fertilizers need to be pulverized in advance, which is conducive to the next step of mixing (if straw and other materials are fermented before fermentation) The tubers are relatively large and need to be crushed simply so as not to affect the normal operation of the turning machine)
3. Mixing and stirring: Here, the horizontal mixer is mainly used for mixing, and the well-fermented and uniformly crushed organic materials are fully mixed with the compound fertilizer, stirred for 3-5 minutes, and then directly transported by the conveyor to the fertilizer granulation The granulation process is carried out in the machine.
4. Fertilizer granulation: Since the mixed material to be granulated is an organic and inorganic mixture, a new type of granulator will be selected for granulation. The drum and internal stirring teeth are used to granulate at high speed at the same time, and the pelleting rate is high. , large output and strong adaptability.
When the output is small, you can choose a general disc granulator or a stirring tooth granulator. For details, please contact us for a detailed introduction.
5. Drying and cooling: This is to quickly evaporate excess water in the granules, which is conducive to packaging and bagging, and prolongs the storage period. When the output is small, only the dryer can be installed or this link can be ignored.
6. Screening and grading: You can screen according to your own needs, and sell the particles with the same particle size and quality as finished products, which can improve the economic value of the product, and the remaining small particles, semi-finished products, powder, etc. return to the crushing process.
7. Customers can also carry out steps such as rounding and whole grain, coating and coating according to their own needs, so as to further enhance the commodity value of their fertilizers. As a farm, in order to deal with the problem of manure pollution in the farm, using organic fertilizer equipment to process manure into manure organic fertilizer is a treatment method that is relatively simple, low in technical difficulty, and relatively low in equipment investment costs.
The technological process of the organic fertilizer production line can be deleted according to the actual situation of the farm, and the production line of granular or powdered organic fertilizer can be selected according to the needs of the surrounding market.
