Organic fertilizer equipment and process flow for processing livestock and poultry manure in farms

How to deal with livestock and poultry manure? How to ferment organic fertilizer? For example, the high water content of chicken manure affects fermentation. You can choose to add auxiliary materials (straw powder, mushroom residue, sawdust, sugar residue, distiller’s grain residue, medicinal residue, etc.) or use a solid-liquid separator to separate dry and wet chicken manure. The separated manure can be returned directly to the fields after sedimentation, and the biogas residue can also be processed into organic fertilizer. The separated dry chicken manure has a moisture content of 40%-60% and can be directly processed into organic fertilizer through aerobic composting fermentation (with biological fermentation bacteria).
1. For example, for 20,000 to 50,000 chickens, a fermentation tank with a width of 3 meters and a length of 50 meters (which can ferment more than 200 tons of raw materials) needs to be built. This machine can have multiple tanks in one machine.
2. Then pile the raw materials (feces, biogas residue, straw) in the fermentation tank, mix 1 kilogram of decomposition agent with 20 kilograms of water, and mix it in the pile of raw materials. 1 kilogram of decomposition agent can ferment 3-5 tons of raw materials (depending on the quality of the biological bacteria). ), according to the raw material comparison, the temperature can rise to about 60~70C°.
3. The fermentation cycle is 7-10 days, and it can be completely decomposed by tossing once every 2 days.
Supporting organic fertilizer production equipment process flow:
1. Ground turning machine or trough turning machine:
The ground compost turner does not need to build a trough, but directly piles the materials into strips. A 260-type or 280-type wheeled compost turner is used to perform compost turning and fermentation in a straddling manner.
Using tank fermentation, you need to build 6 fermentation tanks of 6 meters wide and 40-50 meters long according to your production scale. The fermentation materials are continuously put into the fermentation tanks, and the turning machine is used for turning and fermentation, which can regulate moisture and stir. Uniform purpose, which can save a lot of labor. It can also achieve the purpose of being fully decomposed.
Use a shovel to move the fermented organic fertilizer to the semi-finished product stacking area to facilitate daily handling of the fermented organic fertilizer that has been turned over by the compost turner.
3. Screening machine
The fermented organic fertilizer is sieved to separate out the large chunks and debris to facilitate the next step of crushing and packaging.
4. Crusher
The large debris and stones in the sifted organic fertilizer are sorted out and then crushed, which not only looks beautiful but also ensures the quality of the product.
5. Blender
Pre-mixing the screened and crushed organic fertilizer can ensure the stability of product quality, and at the same time, it plays a mixing role in the production of special fertilizers and various compound fertilizers when adding fertilizers and trace elements.
6. Granulator. Pelletize the material.
7. Dryer, cooler. The prepared pellets are dried and cooled.
8. Packaging machine
The organic fertilizer particles are granulated and directly packaged and sold.
Note: It is recommended to carry out secondary fermentation properly in the post-processing of compost (before air drying), especially for raw materials with a large proportion of livestock and poultry manure in primary fermentation. This can avoid rapid reproduction in secondary fermentation when finished fertilizer is applied to the soil. Microorganisms compete with vegetable roots for oxygen, causing roots and seedlings to burn.
