Equipment and process for processing duck manure organic fertilizer production line

  A duck excretes about 100 grams of feces a day, and 10000 ducks excrete about 1 ton of feces a day. According to the breeding cycle, 40 days to calculate, it will excrete about 40 tons of feces. A duck farm, which sells 1 million ducks a year, excretes about 4000 tons of feces every year. Because of the continuous excretion of excrement, it is a difficult problem that must be solved in duck farm. Next, NPK fertilizer granulator manufacturer introduces how to deal with duck manure in organic fertilizer production line.


Treatment steps of duck manure organic fertilizer production line
1. Mix well the starter: about 3-5 tons duck manure, add appropriate amount of organic fertilizer fermentation agent, rice bran or corn bran, mix well and sprinkle into the prepared materials, the effect is the best.
2. Adjustment of water content: in the process of organic fertilizer fermentation, whether the moisture content is suitable is very important. It should not be too high or too low, and should be kept at 60-65%. Judgment method: hold a handful of materials tightly, see the watermark at the finger joint but do not drip, and it can be scattered on the ground.
3. Building a pile: When making a fermentation pile, it cannot be too small or too short. Too small will affect the fermentation. Generally, the height is about 1.5 meters, the width is about 2 meters, and the length is more than 2 to 4 meters. The fermentation effect is better. The top layer is covered with semi-wet straw (especially for heat preservation during composting in winter). If it rains, you can simply cover it with plastic film, but it does not need to be sealed (Note: Straw decomposing is aerobic fermentation , Can not be sealed, stacked as loosely as possible). In order to avoid rain, if conditions permit, a rain shed can be set above the material to prevent rain from getting wet. Tank fermentation can also be used, which is more convenient.
4. Mix well and aerate: Compost fermentation must be aerobic fermentation, so oxygen supply measures should be increased during the fermentation process, and the stack type compost should keep the materials naturally loose. Holes. It is advisable to mix the materials well, turn frequently, and ventilate, otherwise the fermentation effect of the materials will be affected by anaerobic fermentation.
5. Fermentation is complete: The sign of successful fermentation is that the material has completely lost the odor of feces, on the contrary, there is a slight aroma of biological fermentation. The decomposed material is further processed with a fertilizer granulator.

  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 ...
