It is an important technical link to set up the vent in the composting process of the double axis mixer. The design and setting of ventilation channels directly affect the fermentation process of compost, thus affecting the final fertilizer quality. The following is a detailed explanation of the process.

The design of the vent should take into account the type and amount of compost material, as well as the expected fermentation temperature and other factors. In general, the size and distribution of the pores should ensure sufficient air circulation, but not allow too much outside air to enter, thus affecting the natural fermentation process of the compost.

The setting of the vent channel should be completed before the start of the double-shaft mixer. Generally, the position of the hole should be set at the bottom of the material, and as the fermentation process proceeds, the hole should gradually move upward so that all the materials can be fully fermented.

During the composting process, the opening and closing of the vent channels should be automatically controlled by the control system of the two-axis mixer. When the fermentation temperature rises and more oxygen is needed, the ventilation channels are automatically opened to facilitate the fermentation process. When the fermentation process becomes stable and the temperature is no longer significantly higher, the ventilation channel will automatically close to prevent too much outside air from entering and affecting the fermentation effect.

The setting of ventilation channels in the composting process of the two-axis mixer of organic fertilizer equipment needs to take into account many factors, including the type, quantity, fermentation temperature, the size and distribution of the pores, the location, and the opening and closing time. Only the correct setting and operation can ensure the smooth composting process of the organic fertilizer production line and obtain high-quality organic fertilizer.
