Local overheating is a common problem during the fermentation of cow manure, which can lead to reduced fermentation efficiency and even undesirable consequences. Therefore, how to avoid local overheating has become one of the problems that must be solved in the fermentation process of cow manure. This article will introduce how to avoid local overheating during the fermentation of cow dung from the following aspects.
1. Understand the local overheating phenomenon in the fermentation process of cow manure.
During the fermentation of cow dung, a large amount of heat is generated due to the metabolism of microorganisms. If the heat is not dissipated in time, it will form an overheating phenomenon in the local area. Local overheating will lead to uneven fermentation temperature, which will affect the growth and metabolism of microorganisms and reduce fermentation efficiency. In addition, local overheating may also cause adverse consequences, such as the production of harmful gases and the quality of fermentation products.
2. Measures to avoid local overheating.
1.Control the fermentation temperature.
Controlling the fermentation temperature is one of the key measures to avoid local overheating. In the fermentation process, the fermentation temperature should be reasonably controlled according to the growth and metabolic characteristics of microorganisms. In general, the suitable temperature range for cow dung fermentation is 30-50 °C. If the temperature is too high, you should take measures to cool down in time, such as increasing the amount of ventilation, adding coolant, etc.
2.Increase ventilation.
Ventilation is one of the effective measures to avoid local overheating. By increasing the amount of ventilation, it is possible to promote the dissipation of heat and maintain the uniformity of the fermentation temperature. At the same time, ventilation can also provide sufficient oxygen for microorganisms, promoting the growth and metabolism of microorganisms. Therefore, in the process of cow dung fermentation, ventilation equipment should be reasonably set up according to the fermentation scale and environmental conditions to ensure sufficient ventilation.
3.Add water appropriately.
Moisture is one of the important factors affecting the fermentation process of cow manure. Proper addition of water can promote the growth and metabolism of microorganisms, while also helping to regulate the fermentation temperature. If cow manure is too dry, it can easily lead to local overheating. Therefore, in the fermentation process of cow manure, water should be added reasonably according to the humidity of cow dung and fermentation needs to maintain the suitable humidity of cow dung.
4.Cow manure is stacked evenly.
When stacking cow manure, attention should be paid to even stacking to avoid uneven accumulation. If cow manure is piled up unevenly, it is easy to cause the temperature in the local area to be too high. Therefore, when stacking cow manure, the stacking scheme should be reasonably designed according to the fermentation scale and site conditions to ensure that the cow manure is evenly stacked.
5.Regular inspection and maintenance.
Regular inspection and maintenance is one of the important measures to avoid local overheating. During the fermentation process of cow manure, the fermentation equipment should be regularly inspected and maintained to ensure the normal operation of the equipment. At the same time, fermentation temperature, humidity and other parameters should be monitored regularly to detect and deal with local overheating in time.
3. Summary. Avoiding local overheating is one of the issues that must be addressed during the fermentation of cow manure. The occurrence of local overheating can be effectively avoided by controlling the fermentation temperature, increasing the amount of ventilation, adding water reasonably, evenly stacking cow manure, and regular inspection and maintenance. These measures can not only improve the efficiency of cow manure fermentation, but also ensure the quality of fermentation products and provide high-quality organic fertilizer for agricultural production.
