[0002] Coffee fermentation is an indispensable and important step in the coffee preparation process. Different coffee flavors can be displayed through fermentation control. In order to increase coffee production, the traditional fermentation process can no longer meet production needs, and more and more coffee production companies have begun to use fermentation tanks instead of traditional fermentation methods. At present, when fresh coffee fruits are fermented in a fermentation tank, it is necessary to add the prepared fermentation liquid into the tank. After the fermentation is completed, the tank is emptied and new fresh coffee fruits and fermentation liquid are added. This not only causes a waste of fermentation liquid, but also weakens the flavor of coffee beans, affecting the promotion of the product in the market. In addition, in order to ferment evenly, the existing fermentation tank needs to be equipped with a rotating mechanism to rotate the tank body, which increases energy consumption.
