Aerobic Fermentation Technique Helps to Convert Organic Fertilizer
If you want to have a good fertilizer making state, you need to carry out effective fermentation and decomposing in the early stage. Therefore, the organic fertilizer fermentation tank is very suitable for processing materials and preparing for subsequent production. So what kind of technique can you use in the in-vessel composter to produce organic fertilizer? Of course, it is aerobic fermentation technique. The specific information of this technique is in this article.
Secondly, the fermentation tank has a Roots blower, which sends oxygen through the aeration holes on the stirring shaft, and stirs with the stirring shaft at the same time. Under the action of aerobic bacteria agent, the temperature is gradually raised to 50-65 degrees, and it is fermented and decomposed after more than 7 days of high-temperature fermentation. Effectively kill insect eggs, pathogenic bacteria and weed seeds, and achieve harmless and reduction treatment standards.
Then the materials in the fermentation chamber fall layer by layer under the stirring of the main shaft and the action of gravity. After the fermentation is completed, the finished material is discharged from the discharge port.
What Aspects Should you Pay Attention to During Aerobic Fermentation?
In the process of aerobic fermentation, temperature, oxygen, and humidity will all change, and these three aspects deeply affect fermentation.
Fermentation must begin when the temperature of the organic fermenter reaches 60°C. So how to monitor the temperature of the equipment? When the manure is fermenting in the organic fermentation tank, you can install a temperature sensor to monitor the temperature in the tank in real time. And start the industrial electric blanket (embedded in the two-layer tank wall) to adjust the temperature to ensure the best living temperature (60-70℃) for beneficial bacteria.
In addition, in the upper part of the in-vessel composter, you can also install a heating device. This device heats the oxygen pressurized into the tank to ensure the proper temperature for the fermenter.
Oxygen is the most important thing, without enough oxygen, aerobic fermentation cannot take place. You can press the heated oxygen into the tank through a high-pressure Roots blower to ensure that the aerobic bacteria have enough oxygen. An oxygen sensor also monitor the oxygen concentration in the tank.
The moisture of the material before and after entering the organic fermentation tank is different. And achieving a good state of fertilizer production through equipment adjustment. Therefore, the moisture of the feed material is 50-60%, and the moisture of the output material after successful fermentation is about 30%.
