What are the common compost fermentation equipment and what is the specific role in the fermentation process
Composting process, also known as fermentation process, refers to the degradation and stabilization of organic waste under the proper water content, oxygen concentration and other conditions through the action of microorganisms, so as to achieve the purpose of killing parasitic eggs and harmful microorganisms, reducing volatile substances in waste, and at the same time making the organic matter loose for safe treatment and preservation. Because the materials processed by compost fermentation do not contain pathogenic bacteria and weed seeds, they are suitable for application in soil to improve soil conditions.
Composting fermentation process generally includes fermentation, composting, aeration and other links. The equipment used in these links varies with the type of compost. Stack-type composting is to agitate the material by riding the tipper on the stack, thus playing the role of aeration to achieve the purpose of fermentation. Therefore, the device configuration is relatively simple and the function is single. The tank type aerobic fermentation has a distribution system, a tipping system, an aeration system, etc. The equipment is relatively complete, including: distribution truck, organic fertilizer composter, mobile crane, an aeration system, etc. Let’s introduce the functions of these equipment in the fermentation process.
1、 Organic fertilizer composter. In order to meet the requirements of moisture, acidity and alkalinity in material fermentation, some microbial fermenters need to be added. The tipping machine can give full play to its mixing function, so that the mixing operation can achieve the purpose of uniform mixing, stirring and removing the bottom. It can also improve the permeability of raw materials, make the raw materials become fluffy and elastic, absorb a lot of air at the same time, and raise the temperature of the fertilizer pile. If the temperature is too high, it can also absorb fresh air, so that the temperature can be reduced again, In this way, the alternating state of medium and high temperature is formed, which is beneficial to the growth and reproduction of microorganisms.
2、 Cloth truck. The function of the distributor truck is to evenly distribute the materials in the fermentation tank, so that the forklift does not have to enter and leave the fermentation tank frequently, reduce the cost of raw material transfer, and improve the work efficiency.
3、 Move the vehicle. Each tank-type aerobic fermentation system is generally composed of 8-10 fermentation tanks. However, there is only one tipping machine. In order to save equipment investment, multiple fermentation tanks share one organic fertilizer composter. This requires that the tipping machine be switched between different fermentation tanks. The moving crane plays the role of moving the tipping machine and the distribution truck from one tank to another.
4、 Aeration system. The function of the aeration system is to ventilate and aerate the fermentation materials in the tank, so that the microorganisms in the materials can interact with oxygen, and then make the materials fully ferment to produce valuable humus. The fermentation days can be shortened by aeration.
It can be seen from the above introduction that the organic fertilizer tipping machine plays an important role in the whole compost fermentation process. It is necessary to buy a good tipping machine. The dumping effect is good and the efficiency is high. It also has the functions of mixing, crushing and displacement. It also organically combines the electro-hydraulic technology and has a high degree of automation. It realizes the functions of central remote control and one-button operation. According to the needs of users, it can also realize the real-time transmission of temperature, moisture, oxygen content, etc. in the pile.
