How can cow dung be fermented into organic fertilizer? What machines are needed?

Although cow dung is a good raw material for organic fertilizer, if it is not fermented, it will still emit a bad smell, and will cause disease and insect pests and the risk of burning roots and seedlings. In fact, in recent years, with people's attention to green and healthy food, the sales market of organic fertilizer is also getting better and better. Let's see how cow dung can be made into organic fertilizer.

First of all, we should carry out fermentation. The main purpose of fermentation is to make the cow dung fully decompose at high temperature, so that the bacteria and weed seeds in the dung will be eliminated. The same beneficial fermentation bacteria added will multiply a large number of beneficial microorganisms and improve the various beneficial trace elements of organic fertilizer. During fermentation, we should adjust the carbon and nitrogen ratio of about 25:1, water content of about 55%, and then put in the fermentation agent, The fermentation cycle is about 15-20 days. During this period, it is necessary to carry out regular mixing and temperature control to make the raw materials better contact with oxygen, so as to achieve the goal of accelerating fermentation and ripening. If it is a small amount of operation, we can use manpower or a small agricultural forklift to carry out the tipping treatment. If the amount is large, we need to use a professional cow manure organic fertilizer composter. After the end of the fermentation cycle, our cow manure organic fertilizer will be fermented. However, the organic fertilizer fermented in this way is relatively crude, only suitable for self-use or short-distance sales, and the profit point is also very low. If it can be made into commercial organic fertilizer, the profit per ton should be at least 200-300.

If we want to produce commercialized organic fertilizer, we need to carry out further processing. Powdery organic fertilizer needs to be broken into powder by using cow manure organic fertilizer crusher, and granular organic fertilizer needs to be made into cow manure granular fertilizer by using organic fertilizer granulator. Therefore, we need to determine the production process of organic fertilizer according to the market situation, and determine the production process, so we can configure a complete set of equipment production plan targeted.
