What Is the Production Process of Powder Organic Fertilizer Equipment?
Powdered organic fertilizer production process:
In the production of powdered organic fertilizer, strip-type fermentation is generally used, that is, general stack-type fermentation, which can be carried out in an open field, or can be combined with civil-construction tank-type fermentation. The main difference is that the choice of fermentation turner is different. The fermentation site must be equipped with protective facilities, and care should be taken to avoid wind and rain during fermentation and reduce organic matter.
- Ingredients before fermentation: When the water content of the raw material is too low, water or livestock and poultry urine should be added to increase the water content. When the water content of the raw material is too high, solid-liquid separation machine should be adopted, or the method of adding auxiliary materials should be used to reduce the water content. The auxiliary materials can be straw, peanut shells, and other plant residues. The final moisture content is preferably 45% – 50%.
- After the ratio of the raw materials is good, it should be fully stirred and put into the stacking tank or stacked on the level into strips, 2 meters wide and 1 meter high. Or determine the size of the stack according to the existing organic manure compost turner.
- Adding strains: strains and residues are prepared in a ratio of 1:5, and about 1kg of strains are added for every 15 tons of fecal raw materials, which are evenly sprinkled on the surface of the bar stack, in order to increase beneficial bacteria and improve fermentation. speed.
- Start fermentation: use a crawler-type turner in the open field, and use a trough-type turner for trough fermentation to turn over the pile. When the temperature reaches 60°C or more, turn over and toss every 2 days. After 10 days of fermentation at 60°C, the fermentation work is completed.
- Raw material pulverization: In order to avoid caking during storage, the fermented and decomposed raw materials are also pulverized. A special organic fertilizer pulverizer is used to finely pulverize the raw materials. After the first pulverization, the raw materials need to be pulverized once. Screening, the incompletely crushed sieves are screened out for secondary crushing, and finally a uniform and fine organic fertilizer is obtained.
- At this point, the whole process of powdered organic fertilizer has been processed and can be packaged and sold.
Among them, it should be noted that the ratio of raw materials must be scientific and reasonable to ensure that the finished organic fertilizers meet the standards and are exquisite products, so as to lay a good reputation and promote the better development of enterprises.
