In organic fertilizer production line, fermentation ventilation is very important. Fermentation ventilation can provide sufficient oxygen for the fermentation of organic materials, promote the growth and metabolism of microorganisms, and thus accelerate the decomposition and transformation of organic matter. In addition, ventilation can also effectively regulate the temperature and humidity during the fermentation process, prevent the material from heating and caking, and ensure the quality of fermentation. Therefore, fermentation ventilation has a great impact on the efficient operation of organic fertilizer production lines.

There are two main types of fermentation ventilation: forced ventilation and natural ventilation. Forced ventilation is to force fresh air into the fermentation material through a fan to meet the oxygen demand required for microbial growth. Natural ventilation is the use of the hot gas rise principle generated by the temperature difference between the inside and outside of the fermentation container, so that fresh air naturally flows into the fermentation material. These two ventilation methods have advantages and disadvantages, and the appropriate way can be selected according to the actual production needs and conditions.

In the selection and optimization of fermentation ventilation equipment, the following points should be considered: First, choose suitable production scale and organic fertilizer equipment; Secondly, ensure the efficient operation of ventilation equipment and reduce energy consumption; Finally, according to the actual situation, the ventilation equipment is regularly maintained and maintained to improve the service life of the equipment.

In order to improve the effect of fermentation ventilation, the following strategies and practices can be adopted: First, strengthen the selection and design of fermentation ventilation equipment to improve ventilation efficiency; Secondly, optimize the fermentation process to ensure the uniform oxygen supply of organic materials in the fermentation process; Finally, the monitoring and management in the fermentation process are strengthened, and the ventilation parameters are adjusted according to the actual situation to achieve the best fermentation effect.
