Fermentation can be categorized into two main types: anaerobic and aerobic. For example, the silage fermentation using Kinpo II Fermentation Agent is an anaerobic process, while composting with Kinpo-1 Fermentation Adjuvant is an aerobic process. In anaerobic fermentation, oxygen is not required; it just needs to be properly sealed to create an oxygen-free environment. On the other hand, aerobic fermentation requires the material to remain well-aerated, as microorganisms need oxygen to function effectively. To ensure sufficient oxygen supply during the fermentation process, several aeration methods are commonly used.
First, turning the pile is one of the most effective techniques. In large-scale fertilizer production, machinery such as a Fermentation Fertilizer Machine can be used to turn the pile efficiently. However, for small farmers without equipment, manual turning is necessary. When turning, it's important to do it thoroughly to allow proper air circulation and prevent the material from becoming compacted.
Second, poking holes in the pile is another simple and labor-saving method. This technique is especially useful when working with materials like the Kinpo Matrix Substrate Fermentation Aid. A sharpened wooden stick can be inserted into the pile and then pulled out to create small channels, allowing oxygen to reach the core of the material. The more holes you make, the better the aeration will be.
Third, covering the pile with breathable materials such as straw or sacks is essential. If plastic sheeting is used, it should be placed at least 10–20 cm above the material, supported by bricks or wooden sticks to maintain airflow. Leaving small gaps between the cover and the pile also helps in maintaining good ventilation.
Lastly, using a blower can significantly speed up the oxygen supply, making it ideal for large-scale operations where rapid and consistent aeration is needed. It’s a practical tool that ensures microbes have enough oxygen to work efficiently throughout the fermentation process.
By employing these aeration techniques, you can optimize the fermentation process, improve microbial activity, and ultimately achieve better results in composting, silage production, or any other fermentation-based application.
