The complete set of chicken manure processing organic fertilizer production line products are made from fresh chicken manure, pig manure, sheep manure, cow manure and other livestock and poultry, as well as straw, sludge, etc., as the main raw materials, without any chemical components. So how to operate an organic fertilizer production line to produce fertilizer?

The equipment operation steps of the organic fertilizer production line for chicken manure processing:
1. Preparation work:
Weigh and divide the chicken manure and livestock manure (with a moisture content of about 70%) that needs to be processed; Prepare BM bacterial agents. Mix animal manure and BM bacterial strains in a weight ratio of 1:10000, then stir 2-3 times. The moisture content of the stirred fermented product should be controlled between 55% -60% to achieve the effect of holding it in a ball and letting it go before dispersing. After 10-15 days of stacking and fermentation, it meets the standards of pollution-free and organic fertilizer in China, and can be used as a base fertilizer.
2. The key points and steps of fermenting livestock and poultry manure in organic fertilizer production line:
Step 1: Mix the fermentation agent evenly: Add 1 to 1.5 tons of dry chicken manure (about 2.5-3.5 tons of fresh chicken manure) and 1 kilogram of chicken manure fermentation agent. For each kilogram of fermentation agent, add an average of 5-10 kilograms of rice bran, corn, and bran. Stir well and sprinkle into the prepared materials for better results.
Step 2, Adjusting the Carbon to Nitrogen Ratio: The carbon to nitrogen ratio of the fermented fertilizer should be maintained at 25-30:1, and the pH should be adjusted to 6-8 (pH). Due to the high carbon to nitrogen ratio of chicken manure, some straw, rice straw, mushroom residue, etc. should be added during fermentation.
Step 3: Adjust the moisture content of chicken manure: During the fermentation process of organic fertilizer, it is very important to determine whether the moisture content is suitable. It should not be too high or too low, and should be maintained at 60-65%. The judgment method is to tightly grasp a handful of material, see watermarks on the fingertips but do not drip, and it is advisable to scatter on the ground.
Step 4: Chicken manure pile construction: When making a fermentation pile, it should not be too small or too short, as it will affect fermentation. The height is generally around 1.5 meters, the width is about 2 meters, and the pile with a length of 2-4 meters or more has a better fermentation effect.
Step 5, Mixing and Ventilation: Fermentation aids are aerobic microorganisms, so oxygen supply measures should be increased during the fermentation process to achieve mixing, frequent flipping, and ventilation, otherwise anaerobic fermentation will affect the fermentation effect of the materials.
Step 6, Fermentation completion: Generally, after 48 hours of chicken manure accumulation, the temperature will rise to 50-60 ℃, and on the third day it can reach 65 ℃ or above. Flip over at this high temperature once. In general, there will be 2-3 times of high temperature above 65 ℃ during the fermentation process. Flip over 2-3 times to complete the fermentation. Normally, fermentation can be completed in about a week, allowing the material to completely deodorize, ferment and mature, sterilize and kill insects.
3. Organic fertilizer technology for chicken manure fermentation
After being fermented with livestock manure fermentation agents, the fertilizer efficiency of livestock manure is better, it is safer and more convenient to use, and can also improve the utilization rate of chemical fertilizers. Not only chicken manure can ferment organic fertilizer, but various animal manure, straw, fallen leaves, bark, sawdust, etc. can also ferment organic fertilizer, and the fermentation method is basically the same. Finally, I would like to remind everyone that no matter what materials are used to ferment organic fertilizers, it is important to control the moisture content, otherwise the success will be in vain.
