Goat Dung Organic Fertilizer Production Machine In Manure Organic Fertilizer Production Line

Goat manure is a high-quality raw material for making organic fertilizer. It is rich in nitrogen, phosphorus, potassium and other nutrients and organic matter. After processing, it can become efficient and environmentally friendly organic fertilizer. The following is a detailed introduction to the Goat manure processing organic fertilizer production line, including process, equipment and related points:

2. Core process steps and technical points

1. Raw material collection and pretreatment

• Raw material requirements : Collect fresh Goat manure, and control the moisture content to 60%~65% (it can be squeezed into a ball without falling apart, and water can be seen between fingers without dripping). If the moisture content is too high (such as moisture content > 70%), it is necessary to adjust the moisture content by drying in the sun, mechanical dehydration (dehydrator) or adding crude fiber materials such as straw and rice husk.If the moisture content is lower than this, dehydration is not required.

• Purpose of pretreatment : Reduce moisture content to avoid poor aeration and incomplete composting due to excessive humidity during fermentation, and reduce the load on subsequent equipment.

2. Ingredients and Mixing

• Ingredients :

◦ Goat manure is the main ingredient (accounting for 60%~70%), and conditioners such as straw and sawdust are added (20%~30%, adjusting the carbon-nitrogen ratio to 25:1~30:1).

◦ Maturation bacteria (such as EM bacteria, yeast, etc., added at 0.1%~0.2% of the raw material amount) can be added to accelerate the fermentation process.

◦ If you need to improve the fertilizer efficiency, you can add appropriate amounts of nitrogen, phosphorus and potassium fertilizers (such as superphosphate, potassium sulfate) or trace elements (boron, zinc, etc.).

• Mixing equipment : horizontal mixer, double-shaft mixer, to ensure uniform mixing of materials and lay the foundation for fermentation.

3. Fermentation and ripening (key link)

• Fermentation method :

◦ Strand fermentation : pile the mixed materials into strips 1.5~2 meters high and 2~3 meters wide, and use a straw turner to turn them regularly (once a day in the early stage and once every 2~3 days in the later stage) to ensure oxygen supply and promote the reproduction of aerobic microorganisms.

◦ Tank fermentation : carried out in a fermentation tank, turned by a tank turner or a crawler turner, with a high degree of automation, suitable for large-scale production, and a fermentation cycle of about 15 to 25 days.

• Fermentation control parameters :

◦ Temperature: At the beginning of fermentation, the temperature rises to 50~60℃ and is maintained for 3~5 days to kill pathogens, insect eggs and weed seeds; after the high temperature period, the temperature gradually drops to below 40℃, indicating that the composting is complete.

◦ Humidity: Maintain 50%~60%. Spray water when it is too dry. Turn and ventilate when it is too wet.

◦ Fermentation cycle: Conventional strip fermentation takes about 30 to 45 days, while tank fermentation can be shortened to 15 to 20 days.

• Maturity judgment criteria : The material is dark brown in color, odorless, with a faint musty smell, loose in texture, easily broken by hand, with an organic matter content of ≥45% and a moisture content of ≤30%.

4. Crushing and screening

• Crushing equipment : semi-wet material crusher, hammer mill, crush the decomposed Goat dung blocks to a particle size of ≤5mm for subsequent granulation.

• Screening equipment : Vibrating screen (10~20 mesh), screen out unqualified coarse particles, return them to the crusher for re-crushing to ensure uniform particle size of the material.

5. Granulation (select according to demand)

• Granulation method and equipment :

◦ Disc granulator : simple structure, small investment, suitable for small and medium-sized production, spherical particles, particle size 2~5mm, granulation rate 70%~80%.

◦ Extrusion granulator : through mechanical extrusion molding, the granules have high hardness, suitable for making organic fertilizer with uniform granules, with a granulation rate of more than 85% and low energy consumption.

◦ Drum granulator : suitable for large-scale production, high output (5~10 tons/hour), good particle strength, but the equipment investment is relatively large.

• Granulation conditions : The moisture content of the material is controlled at 20%~25%, the temperature is 30~40℃, and a small amount of binder (such as bentonite, the addition amount is ≤5%) can be added before granulation to improve the granulation rate.

6. Drying and cooling

• Drying equipment : Rotary dryer, using hot air (temperature 80~120℃) to reduce the moisture content of the particles to below 10%. The drying time is about 30~60 minutes, and the output depends on the equipment specifications (such as Φ1.2×12m dryer, the output is about 1~2 tons/hour).

• Cooling equipment : counter-current cooler or air-cooled cooler to reduce the pellet temperature to ≤ ambient temperature + 5℃ to avoid moisture and agglomeration during storage.

7. Screening and packaging

• Screening : The particles are screened out through the vibrating screen again to obtain qualified particles (2-5 mm). The unqualified particles are returned to the granulator for reprocessing.

• Packaging : Automatic weighing and packaging machine, packing into 25kg, 50kg bags, or ton bags according to needs, labeling and storage.
