Equipment flow of organic fertilizer production from pig manure
Pig manure contains 15% organic matter, 0.5% nitrogen, 0.5-0.6% phosphorus and 0.35-0.45% potassium. Pig manure has fine texture and complex composition, including protein, fat, organic acid, cellulose, hemicellulose and inorganic salt. Because it contains more nitrogen, the ratio of carbon to nitrogen is small, about 14:1. Generally, it is easy to be decomposed by microorganisms and release nutrients that can be absorbed and utilized by crops.
The pig manure produced by the fertilizer production machine has the highest humic matter content, the largest amount of cation exchange and the strongest fertility preservation, but it has more water content and less cellulose decomposing bacteria. It can greatly increase the fertilizer efficiency by mixing a small amount of horse manure to inoculate cellulose decomposing bacteria.
The equipment required for the pig manure granular organic fertilizer production line generally includes:
1. Forklift 2, dumper 3, quantitative feeding vibrating silo 4, crusher 5, roller screening machine 6, belt conveyor 7, electronic dynamic batching scale (optional) 8, mixing mixer 9, organic fertilizer granulator 10, roller dryer 11, roller cooler 12, coating machine (optional) 13, automatic quantitative packaging machine.
Equipment and technology of pig manure organic fertilizer production line
1. The recovered livestock and poultry manure directly enters the fermentation area. After one fermentation and two aging stacks, the odor of livestock and poultry manure is eliminated. At this stage, fermentation strains can be added to decompose the crude fiber, so that the particle size requirements after crushing meet the particle size requirements of the fertilizer granulator.
2. Pulverize the fermented materials that have completed the second aging and stacking process and enter the mixing mixer. Before mixing, according to the recipe, add N, P, K and some other trace elements to the mixing mixer to start mixing.
3. Transfer the mixed materials to the granulator, granules pass through the dryer and enter the cooling machine, the materials will be sieved after reaching normal temperature, and the particles that meet the requirements will enter the coating machine to wrap the coating film and start packaging, which does not meet the requirements The granules are crushed by the crusher and then returned to the granulator to continue organic manure production.
4. Automatic packaging of finished products.
