When it comes to small-scale organic fertilizer production lines, many people may think that it is the organic fertilizer processing method made by farmers that pollutes the surrounding air and groundwater, but it is not always the case. The reason for this concept is that the division of large-scale, small-scale and medium-scale organic fertilizer production line equipment is not very clear. According to the general classification standard of organic fertilizer equipment manufacturers. Organic fertilizer production line equipment with an annual output of less than 20,000 tons belongs to small organic fertilizer production lines. The small-scale organic fertilizer processing technology that pollutes the air and groundwater in the family workshop is only used for small-scale farms or family breeding, and the output is mostly below 3,000 tons a year. This will be phased out gradually. Qualified commercial small-scale organic fertilizer production lines cover an annual output of 3,000 tons to 20,000 tons, and require investment in professional organic fertilizer equipment—organic fertilizer turners, pulverizers, granulators, etc. These are currently in line with environmental protection conditions, protected by the state. Let’s talk about the production method of this small-scale organic fertilizer production line that is environmentally friendly and supported by state finance.
Small organic fertilizer production line process:
The process of small organic fertilizer production line generally adopts tank fermentation or tank fermentation, and the other is advanced biogas production, and then fermented into organic fertilizer. This is a relatively common early stage of organic fertilizer processing in the market.
The initial process method of small organic fertilizer production line is as follows:
The fertilizer base materials such as livestock manure and other materials, domestic garbage, sludge, etc. are piled on the flat ground in strips. (The trough turning machine directly puts the material into the trough), the stacking width is equal to the turning width of the equipment, the height should be as high as possible, and the length should be as long as possible, such as 50 meters, 100 meters, etc., the ground should be flat, cement, The land can be used (as long as it is flat and has a certain hardness), each 10,000 tons of production requires a site of 5-6 acres, and the trough type turning machine will cover a relatively small area).
Sprinkle the piled livestock and poultry manure and other materials, domestic garbage, sludge and other fertilizer base materials with biological fermentation bacteria agent (this unit provides technology and fermentation bacteria agent).
Use a heap turning machine or a trough turning machine to evenly mix straw, livestock and poultry manure and other materials, domestic waste, sludge, (water content should be 50%-70%), fermentation bacteria, etc. for 3-5 hours. It can deodorize, heat up to 50 degrees in 16 hours, when the temperature reaches 55 degrees, turn over again to increase oxygen, and then start to mix when the temperature of the material reaches 55 degrees, which has the effect of uniform fermentation, oxygenation, and cooling. A process until fully decomposed.
If the water content of livestock and poultry manure and other materials, domestic waste, sludge, etc. is too high, you can add organic matter, relatively dry auxiliary materials that can absorb water, or use the method of backflow to put the last dried fertilizer below to form strips. Put livestock and poultry manure and other materials, domestic garbage, sludge, etc. with a large water content in the middle, so that the water on the top can seep to the bottom and then turn it over.
The general fertilization process takes 7-10 days. Due to different climates, it may take 10-15 days for the material to be completely decomposed, achieving no odor, no germs, eggs, weed seeds, and high humus content. Potassium increased nutrient content, etc. Powdered organic fertilizer is made.
Then, equipment such as pulverizer, grading sieve, automatic packaging machine packaging, etc. are carried out, and the powdered organic fertilizer can be put into storage and sold.
If it is a powdered organic fertilizer, it can be sold in the market after the above-mentioned preliminary process is completed. However, considering the inventory time and fertilizer efficiency maintenance as commodity sales, it needs to be further processed into granular organic fertilizer in the above-mentioned process.
Processed Granular Organic Fertilizer:
When processing into granular organic fertilizer, the process of small organic fertilizer production line is described above with the following process flow: ① Use organic fertilizer granulator to process into 3mm-5mm-8mm and other particles; ② Screening machine for screening; ③ After screening, the granules that meet the specifications enter the lower-level process, and those that do not meet the requirements are returned to the pulverizer for reprocessing and granulation again; it should be noted that the primary granulation rate of Tongda Heavy Industry Organic Fertilizer Granulator reaches more than 95%; ④ Those that meet the requirements Transfer to dryer, cooler for drying and cooling; ⑤ In order to maintain fertilizer, the granules also need to be coated, that is, the coating process of the coating machine; ⑥ The coated granules are transported to an automatic weighing and packaging machine for packaging; ⑦ Warehousing.
