Pig manure fermentation Manure production line to improve resource utilization

Pig manure is suitable for all kinds of soil and crops, especially for well-drained soil. The transformation of pig manure into organic fertilizer requires collection, adding organic matter carrier, turning pile fermentation, grinding, screening, mixing of ingredients and granulation packaging, and then making natural organic fertilizer.

A complete organic fertilizer production line fermentation process of pig manure:

1. Prepare materials and bacteria: Prepare the manure to be fermented, and mix pig manure starter with rice bran at a ratio of 1:5 ~ 10 for use.

2. Build a pile of pig manure: build a pile of prepared pig manure while spreading bacteria.

3. Mix well and aerate. Pig manure starter requires good (consumption) oxygen fermentation, therefore, oxygen supply measures should be increased in the operation process, so that mixing, frequently turning, ventilation is appropriate. Otherwise, it will lead to anaerobic fermentation and produce odor, affecting the fertilizer effect.

4, fermentation and maturation of organic materials sifting, requiring uniform fineness, must reach the harmless standards of organic fertilizer, such as pathogenic bacteria, eggs, weed seeds, heavy metals content control in the national standards, from the source to eliminate the production of unqualified products.

5, inorganic material processing, need to be crushed should be moderately crushed.

6. Mix and stir in proportion. Dynamic batching equipment can be applied if necessary.

7. If granulation needs to be dried and cooled. In order to prevent fertilizer from caking for a long time, it is usually appropriate to add bentonite, gypsum powder, talc powder and other powders.

8. Product inspection, packaging and warehousing.

The use of livestock and poultry waste to produce organic fertilizer has broad market prospects and outstanding ecological benefits, which is an important development trend of livestock and poultry waste treatment in the future. Therefore, it is necessary to strengthen the technical research of bio-organic fertilizer production and further improve the utilization level of resources, in order to achieve both economic and environmental benefits.
