With the continuous improvement of international agricultural environmental awareness, fertilizer quality has been in the wave of social discussion. As the core equipment of organic fertilizer production, the composting machine can effectively improve the quality of organic fertilizer by improving the role of microorganisms in the fermentation process. This article will start from the improvement of the interaction effect of the composting machine on microorganisms during the fermentation process, and analyze the improvement of the fermentation effect of the composting machine on organic fertilizer, aiming to provide you with some reference.

1. Effect of composting machine on microorganisms

① Provide a suitable environment for microorganisms

The composting machine provides a stable fermentation environment for microorganisms during the fermentation process. In the early stage of fermentation, the composting machine will provide sufficient oxygen for mesophilic microorganisms by accurately adjusting the ventilation frequency and stirring intensity to ensure the activity of microorganisms. When the fermentation enters the high temperature stage, the composting machine will increase the temperature in the tank to ensure that the thermophilic microorganisms that play a leading role in this stage can survive and reproduce in a suitable environment.

② Regulate the microbial fermentation process

The composting machine for accelerating microbial fermentation is equipped with a precise detection system and regulation system, which will accurately regulate the fermentation process of the microorganism. Ensure the temperature, oxygen concentration and pH data indicators in the composting machine with high – efficiency, and accurately regulate the microbial fermentation process.

③ Improve the effect of microbial action

During the fermentation process, through the regulation of the composting machine with intelligent microbial interaction design, the efficiency of microbial treatment of waste is significantly improved. Compared with the traditional composting method, the fermentation cycle can be shortened by half or more, greatly improving the production efficiency.

2. Analysis of composting machine’s microbial fermentation process

The microbial fermentation process in the composting machine with precise temperature and humidity control is a complex and orderly process, which can be mainly divided into three key stages: heating, high temperature and cooling.

① Heating stage

The temperature in the composting machine is 15-45 degrees Celsius, mesophilic bacteria are active, soluble sugars, starch, etc. are consumed rapidly, and the temperature continues to rise; mainly bacteria, fungi, and actinomycetes; in the early stage of composting, the pile is basically mesophilic, and mesophilic microorganisms are more active, and they use the soluble organic matter in the compost to reproduce vigorously. In the process of converting and utilizing chemical energy, part of them becomes heat energy. Because the pile has a good insulation effect, the temperature continues to rise.

②High temperature stage

The temperature in the composting machine facilitating microbial recycling of organic materials rises to above 45 degrees Celsius, even up to 65-70 degrees Celsius, and then gradually decreases. When the temperature rises to 60 degrees Celsius, the fungi almost completely stop moving. When the temperature rises to above 70 degrees Celsius, it is no longer suitable for most thermophilic microorganisms. Much of microorganisms die or enter a dormant state. Except for some spores, all pathogenic microorganisms will die within a few hours, and other seeds will also be destroyed.

③Cooling stage

In this stage, the microorganisms in the composting machine with high – efficiency become active again and become dominant bacteria again, further decomposing the residual organic matter that is difficult to decompose. The humus continues to increase and stabilize. When the temperature drops and stabilizes at around 40 degrees Celsius, the composting is basically stable.

3.Composting machine increases performance by utilizing microorganisms

①Improve efficiency

During the fermentation process, the control system of the composting machine for accelerating microbial fermentation will accurately control the temperature, pH, oxygen concentration, etc. in the fermentation environment to ensure that the microorganisms ferment in a suitable environment. In addition, Bolong has also specially developed and designed a stirring wing. It adopts the diamond shape and inclined installation angle, which can reduce the stirring resistance and increase the stirring force of the waste, ensuring that the waste and microorganisms can fully contact and the fermentation process can be fully carried out. The strict control of these factors has achieved the stability of the fermentation process and shortened the fermentation time.

② Improve environmental friendliness

The tank body of the Bolong composting machine with high – efficiency is a sealed structure, which greatly reduces the emission of exhaust gas. In addition, Bolong has exclusively designed a heat exchange deodorization system. When the exhaust gas passes through the system, it will be quickly condensed, further reducing emissions. At the same time, the heat will be recycled into the tank for reuse. The gas treated by this system meets the environmental emission standards and can be directly discharged into the atmosphere. This design saves energy while reducing environmental pollution.

The close cooperation between the composting machine and microorganisms plays an irreplaceable and important role in the fermentation process of organic fertilizer. From the benign interaction with microorganisms to the precise control of the microbial fermentation process, the composting machine will continue to promote the advancement of organic fertilizer production technology and contribute more to international green agriculture.
