How to ensure that the oxygen content in the fermentation material is divided into anaerobic fermentation and aerobic fermentation, such as the fermentation of silage using the second generation fermenter of anaerobic fermentation is anaerobic fermentation, and the use of the Kinpai type of fermentation auxiliaries Composting is aerobic fermentation. Anaerobic fermentation does not require oxygen to participate, as long as it can be sealed; and aerobic fermentation requires the material to be breathable, to avoid microbes due to lack of oxygen and can not work. The following are some commonly used methods of aeration in the fermentation process to supply enough oxygen to maintain the fermentation. First of all, turn over. For example, a Fermentation Fermentation Fertilizer Fertilizer Fertilizer, a large-scale fertilizer plant can be used to turn over the stack directly, and the farmers own no machinery, and can only turn over by hand. When turning, it should be as detailed as possible to achieve the purpose of ventilation and ventilation.
Second, punch holes. This method can save labor, operation is relatively simple, suitable for less labor users. Insert a wooden stick into the stack of materials (the wooden stick can be sharpened) and pull out to form a hole. The quantity should be as much as possible. Such method can be adopted when fermenting culture materials such as Kinpo Matrix Substrate Fermentation Aid.
Again, cover. The material fermentation cover should be made of straw, sacks, and other breathable materials. If covered with plastic sheeting, it should be padded with bricks and wooden sticks, 10-20 cm from the surface of the material. Also, proper gaps should be left to allow oxygen to enter.
Finally, the blower. The use of a blower speeds up oxygen supply and can be used appropriately.
