The application of mobile dump trucks in the fermentation process of organic waste mainly involves the following key steps, which together constitute a complete fermentation process:
Raw material preparation: Firstly, the organic waste that needs to be fermented, such as livestock manure, crop straw, food processing waste, etc., is subjected to preliminary treatment, including crushing and mixing, to ensure the uniformity and suitable particle size of the raw materials, which is conducive to the growth of microorganisms and the fermentation process.
Composting pile construction: The process of stacking processed raw materials into long, rectangular piles of a certain height and width, commonly referred to as "fermentation piles". The size and shape of the fermentation pile will be determined based on the type and quantity of raw materials, as well as the specifications of the mobile tipping truck.
Fermentation initiation: After the compost pile is built, microorganisms begin to decompose organic matter under suitable temperature, humidity, and oxygen conditions, and this process is called fermentation initiation. The activity of microorganisms generates heat, causing the temperature of the pile to gradually increase and enter the high-temperature fermentation stage.
Pile flipping operation: When the temperature of the pile reaches a certain height (usually between 50-70 ° C) and is maintained for a period of time, a mobile pile flipping truck is used for the flipping operation. The dump truck flips the pile to mix the internal and external materials, increase oxygen supply, promote microbial activity, and evenly distribute the temperature and humidity of the pile to prevent local overheating or excessive humidity.
Repeated flipping: During the fermentation process, it is necessary to regularly flip the pile according to the temperature and fermentation status of the pile. The frequency and timing of flipping depend on the temperature of the pile, the properties of the raw materials, and the progress of fermentation.
Maturity stage: When the temperature of the heap gradually decreases and no longer significantly increases, fermentation enters the maturation stage. At this point, most of the organic matter has been decomposed by microorganisms, the temperature of the compost pile tends to stabilize, and compost products begin to form.
Post processing and storage: After fermentation, compost products need to undergo further processing such as screening, crushing, drying, etc. to remove impurities, adjust particle size and moisture, and finally be packaged and stored for transportation and use.
The key role of mobile dump trucks in the fermentation process is to increase the oxygen supply to the pile, promote microbial activity, accelerate the decomposition of organic matter, and ensure uniform temperature and humidity of the pile, thereby improving fermentation efficiency and the quality of compost products. This process can not only effectively handle and utilize organic waste, but also promote the recycling of resources, providing sustainable solutions for agriculture and environmental protection industries.
