Composting treatment of pig manure organic fertilizer composter

 The complete set of organic fertilizer equipment needs fermentation and turning machine, organic fertilizer grinder, drum screening machine, horizontal mixer, fertilizer granulator, rotary dryer, cooler, screening machine, coating machine, packaging machine, conveyor and other equipment.


Fermentation is the first step of pig manure organic fertilizer production. Composting fermentation is widely used in organic fertilizer production. So what are the complete steps of pig manure fermentation?
Treatment requirements of compost turning machine
1. Temperature requirements. The start-up temperature should be above 15 ℃ (it can be operated in four seasons and not affected by seasons. Fermentation should be conducted indoors or in Greenhouse in winter).

2. Materials are piled up. When doing heap, it should not be too small or too short. If it is too small, fermentation will be affected. The height is 1. The results showed that the fermentation effect was better when the length was more than 2-4 meters and 5-2 meters. Many organic fertilizer plants use fermentation tank for fermentation. The tipper can move flexibly on the track, with large treatment capacity and high efficiency.

3. Turn over the pile for ventilation. During the fermentation process, proper oxygen supply and composting should be paid attention to (overturn several times when the temperature rises to 75 ℃) and the temperature should be controlled at about 65 ℃. If the temperature is too high, the nutrients will be affected.

4. Fermentation is complete. Generally, the fermentation can be completed within a week, the material is dark brown, and the temperature begins to drop to room temperature, indicating that the fermentation is complete. If there are too many auxiliary materials such as sawdust, wood chips, and rice husks, the fermentation time should be prolonged until fully decomposed. After being decomposed, it is further processed by rotary drum granulator.

5. Material ratio. 1.5 tons of pig manure (about 2.5 tons of fresh manure) plus 1 kg of fertilizer starter, the starter must be mixed with rice bran (or bran, corn flour and other substitutes) in a ratio of 1:5, and then evenly sprinkled Put it into the pig manure pile and mix evenly.

  There is a huge demand for bio organic fertilizers in China, especially for some economically efficient and high-quality bio organic fertilizers, which are more popular among farmers. Therefore, opening an organic fertilizer equipment processing fertilizer factory can yield substantial returns. Organic fertilizer trading market. The production of green fruits and vegetables cannot be separated from organic fertilizers. A large amount of organic fertilizer is piled up and wasted in urban areas, and there is a huge demand gap for organic fertilizer in rural areas. If a rural organic fertilizer trading market is established, a bridge between supply and demand can be established, and the production of organic fertilizer through processing of bio   organic fertilizer equipment   can turn waste into treasure. How much does the entire set of equipment for processing bio organic fertilizers cost? 1. Determine the size of  organic fertilizer equipment , such as the annual p...

  Organic fertilizer is a natural fertilizer, but also an important part of sustainable development of human agriculture, so people pay more and more attention to the production of organic fertilizer. The following introduces the main production process of  organic fertilizer production equipment  and the relevant situation of organic fertilizer fermentation equipment. Organic fertilizer production process is generally divided into: fermentation, crushing, ingredients, mixing, molding, drying, cooling, screening, packaging. Of course, some high-end fertilizers will add slurry to make the fertilizer look more beautiful. 1. The first is the fermentation equipment. Most organic fertilizer manufacturers will use the composting fermentation. The key point of composting fermentation is the strain. Only when there are good strains can we get high-quality organic fertilizer. Then there is the crushing equipment. The more commonly used crushing equipment in the organic fertilizer ...
