What are the influencing factors in organic fertilizer production line

What are the influencing factors in the organic fertilizer production line and how can we control them? Let's talk about it.

The main environmental factors affecting fermentation in organic fertilizer production line are temperature, moisture and C / N. In the process of industrial fermentation, the rapid progress of fermentation can be promoted by artificial regulation.

A. Temperature
Temperature is an important indicator of microbial activity in fermentation, and suitable temperature can ensure the good operation of fermentation process.

B. Moisture
Water is an indispensable factor in microbial activities in organic fertilizer production line. In the fermentation process, too high or too low water content of materials will affect the microbial activity, so water regulation should be carried out before fermentation. According to different conditions, the water content is generally between 30% and 70%.

C. C / N ratio
C / N is an important nutritional condition for microbial activity. Generally, the suitable C / N for microbial reproduction is 20-30. The average C / N ratio of pig manure was 14 and that of chicken manure was 8. Simple manure is not conducive to fermentation, so it needs to be mixed with materials with high C / N ratio. The results showed that the suitable amount of the mixture was 14% - 15% for rice straw, 3% - 5% for sawdust, 12% - 14% for dregs and 5% - 10% for peat. Rice husk, cottonseed husk and corn straw are all good admixtures, and the dosage is generally 15% - 20%.

Process flow of 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 machine.

2. Pulverize the fermented materials that have completed the second aging and stacking process and enter the mixing mixer. Before mixing and 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 fertilizer granulator machine, 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 granulation.

4. Automatic packaging of finished products.
