Pig manure organic fertilizer production line equipment
Introduction of pig manure organic fertilizer production line:
In the pig manure organic fertilizer production line, there are two steps to process commercial organic fertilizer: the early fermentation and treatment part and the deep processing granulation part. Pig manure organic fertilizer granule production line is mainly equipped with the following equipment: tipper, crusher, batching machine, mixer, granulator, dryer, cooler, screening machine, coating machine, automatic packer. The general production steps are as follows: raw material fermentation, raw material mixing, raw material granulation, particle drying, particle cooling, particle grading, finished product coating, and finished product packaging.
Pig manure organic fertilizer fermentation:
1. Feed preparation and adding bacteria: the pig manure organic fertilizer production line should prepare the manure to be fermented, the better is fresh pig manure (the fermentation effect of fresh manure is better than that of old manure), for example, about 1 ton of fresh pig manure plus 0.25 kg pig manure fermentation agent. The pig manure starter should be mixed with rice bran (or corn flour, wheat bran) in the ratio of 1:5-10.
2. Construction of pig manure pile: the prepared pig manure should be built while spreading bacteria. The pile height and volume should not be too low or too small. Requirements: pile height 1.5-2 m, width 2 m, length unlimited.
3. Adjust moisture. The moisture content of fermented pig manure should be controlled at 40-65%. Moisture judgment: hold a handful of pig manure tightly, see the watermark but do not drip, and disperse immediately after landing. Less water, slow fermentation, more water, poor ventilation, will also lead to "spoilage bacteria" work and producing odor, therefore, we must grasp the moisture content.
4. Startup the temperature. The start-up temperature of organic fertilizer production should be above 15 ℃ (it can be operated in four seasons, not affected by seasons, and should be fermented indoors or in the greenhouse as far as possible in winter), and the fermentation temperature should be controlled below 70-75 ℃.
5. Mix well and ventilate. Pig manure starter needs good (consumption) oxygen fermentation, therefore, in the process of preparation, oxygen supply measures should be increased, and it is appropriate to mix well, turn frequently, and ventilate. Otherwise, it will lead to anaerobic fermentation and produce odor, which will affect the effect of fertilizer.
6. The fermentation was completed. Generally, after 48 hours of pig manure accumulation, the temperature rises to 50-60 ℃, and it can reach 65 ℃ or above on the third day. Under this high temperature, it needs to be overturned once. Generally, the fermentation process will have two times of high temperature above 65 ℃. The fermentation can be completed after two times of overturning, and the fermentation can be completed within one week. The material was dark brown, and the temperature began to drop to normal temperature, indicating that the fermentation was completed.
The benefits of pig manure organic fertilizer:
Pig manure organic fertilizer has complete nutrition and a long-term fertilizer effect. Pig manure organic fertilizer production not only contains amino acids, protein, sugar, and other organic nutrients but also contains n, P, K, medium elements (Ca, Mg, s, etc.), and trace elements (Fe, Mn, Cu, Zn, etc.) that are beneficial to crop growth. On the premise of increasing the organic matter, nitrogen, phosphorus, potassium, calcium, magnesium, and various trace elements in the soil, compared with chemical fertilizer, organic fertilizer is slowly humic decomposition in the soil, and the fertilizer effect is more lasting.
The process flow of pig manure organic fertilizer production line is as follows:
① Raw material fermentation - ② automatic batching system with scale - ③ crushing and mixing - ④ disc granulation, drum granulation, extrusion granulation - ⑤ dryer drying of organic fertilizer particles - ⑥ cooling machine cooling of organic fertilizer particles - ⑦ Screening machine Screening qualified organic fertilizer particles - ⑧ Coating machine coating particles, smoother - ⑨ Automatic filling of organic fertilizer particles by packaging scale - ⑩ Sealing.
