Cow dung is mainly treated by cow manure fertilizer pellet machine. There are two common business models for cow dung processing organic fertilizer, one is self-produced and sold, and the other is rich in cow dung resources around, which can be independently built to produce organic fertilizer in batches. The mode of self-production and self sale is generally small cow manure fertilizer pellet machine, with an investment of about $100,000.
The equipment required for the production line of cow manure organic fertilizer includes: cow manure dumper, hammer mill, mixer, cow manure fertilizer pellet machine, screening machine, dryer, and automatic packaging machine. One step fermentation treatment in the production process is the key point in the whole process. The effect of fermentation determines the overall quality of cow manure organic fertilizer. The subsequent processing process mainly deals with the appearance of organic fertilizer, in order to increase the appearance of the product.
With the development of social economy and the improvement of people’s quality of life, the demand for beef, mutton, chicken and pork is increasing every year. The state also supports the development of agriculture, especially the development of aquaculture.
The scale of the breeding industry continues to increase, and the treatment of cattle, sheep, chicken and pig manure has become a problem. So how to deal with it? Here we introduce the concept of organic fertilizer. Organic fertilizer is made from animal excrement, sludge and straw, and then used in vegetable, flower and other industries.
How can these things be processed into organic fertilizer? Take cow dung as an example. The first step to make organic fertilizer is to ferment cow dung with fermentation equipment (such as tilter). The fermentation time is about 15 days, and it takes about half a day to use the fermentation tank. After fermentation, it is basically successful. At this time, it needs to be crushed by a grinder. After crushing, it is the organic fertilizer, commonly known as powdered organic fertilizer.
There is also a granular organic fertilizer on the powdered organic fertilizer. It is to make powder into granules through the cow manure fertilizer pellet machine. The process involved here is a little complicated. The first step in the early stage is also fermentation. After fermentation, it needs to be crushed. After crushing, it is granulation. After granulation, it is followed by drying, cooling, coating and molding.
When cow dung is used as raw material to make organic fertilizer, it needs to be fermented first. The cow dung itself has a comprehensive nutrient composition. It is not only rich in a large amount of organic matter, nitrogen, phosphorus, potassium and other trace elements and other plant essential nutrients, but also contains various biological enzymes and microorganisms. However, they can only be absorbed in the fermented and decomposed cow dung. Otherwise, the harmful substances in the cow dung will affect crops, not only do not provide nutrients, but also cause seedling burning, pest damage and other hazards.
The cow dung fermentation adopts compost fermentation turner, and then some microbial strains are added to promote the fermentation process. Cow dung and bacterial strains are evenly mixed and stacked in a built fermentation tank. When the materials rise to a certain temperature, the dumper is used to turn them over, reducing the temperature to facilitate the breeding of bacterial strains. Crawler type dumper can also be used for fermentation. Compared with tank type fermentation, it does not need to build a special tank and is more convenient to use.
From the perspective of granulation production process, a cattle manure organic fertilizer production line mainly includes mixing, granulation, packaging and other links. As the granulation is made by using water crop media to bond the materials together, water will be added to the mixer for mixing during fertilizer production. After the granules are produced, the materials will be dried to remove water, cooled to room temperature, screened for appropriate granules and finally packaged.
1. The organic fertilizer production line should be built in a place with high and flat terrain, good drainage and not too high groundwater level. In this way, it can avoid the loss of raw materials and finished products caused by the ground water in rainy season.
2. The raw material of organic fertilizer is large in volume and weight, which is not convenient for transportation. If the distance is too far, the transportation cost will increase. The plant site should be close to the origin of main raw materials.
3. The plant shall be far away from the working and living areas of residents. This is to avoid the foul smell of raw materials affecting the life or work of residents.
There are many equipment in the whole cow manure organic fertilizer production line. In order to ensure the normal and orderly continuous production, the control system is recommended to use the combination of centralized control in the central control room and on-site control. The control cabinet is set in the control room to start and stop the equipment. The equipment that is far away can be configured next to it for the convenience of subsequent installation, commissioning, maintenance and other operations.
