With the development of society, there's an increasing preference for eco-friendly foods. Foods grown with organic fertilizers are gaining popularity, as these fertilizers are derived from abundant sources like fallen leaves, straw, and animal manure. Compared to chemical fertilizers, organic fertilizers offer higher nutritional value and don't degrade soil quality, causing issues like compaction and poor aeration. Liquid organic fertilizers are a crucial source, easily absorbed by soil and play a significant role in boosting crop yields, making them popular among farmers. However, the fermentation of organic fertilizers typically occurs in fermentation ponds or tanks, generating a lot of heat that requires stirring for cooling. Currently, fermentation pit turnover equipment is used for this purpose, which is costly and inconvenient. Moreover, the large amount of heat produced during fermentation is not utilized, leading to a waste of resources.
