[0011] The beneficial effects of the present invention are as follows: by arranging a feeding mechanism in the center of the lid, the weighed nutrients can be poured into the rotating tube through the two sides of the U-shaped fixing frame at the upper end of the rotating tube. When nutrients need to be added, the handle is pressed downward to compress the spring, so that the fixing rod drives the conical plugging cover at the lower end of the rotating tube to move downward and separate from the lower tube mouth of the rotating tube, thereby pouring the nutrients temporarily stored in the rotating tube and the conical plugging cover into the middle part of the raw materials in the tank body, avoiding splashing onto the inner wall of the tank body and causing loss, thereby improving the stability of feeding and reducing the frequency of repeated adjustment of the pH value by the later inspection personnel due to lack of nutrients, thereby improving the preparation efficiency. In addition, the feeding mechanism is easy to operate and clean later. BRIEF DESCRIPTION OF THE DRAWINGS
