After the material is turned to the top of the tank body, it will automatically fall through the self-weight of the material, and because the first stirring piece and the second stirring piece are arranged in a spiral circle, the material can form a circular flow. Turn over and fall to achieve the purpose of fully mixing the materials. After the mixing is completed, the materials are discharged from the tank body through the discharge port at the bottom of the tank body through the reversal of the mixing blades; the utility model has a simple structure and a reasonable design, and adopts a vertical structure. During the mixing process, the mixing blade will not compact the material, but can perform circular mixing on the material. The mixing efficiency is high and the effect is good, and the use of two stirring blades can improve the mixing capacity, that is, increase the production capacity, and adapt to large-capacity production. The use of fermenters. The utility model enables solid fermented materials to be fully and uniformly mixed, and can separate excess water in the materials, which is convenient and quick to discharge, saves time and labor, and will produce good economic and social benefits after being widely popularized and applied.

Further, the first stirring piece and the second stirring piece are interlaced and spirally surround the stirring shaft around the stirring shaft, and the first stirring piece and the second stirring piece are connected to the stirring shaft through a bracket.

Further, the discharge mechanism includes a cylinder with a material guide channel under the discharge port, the material guide channel communicates with the discharge port, a discharge shaft is arranged in the material guide channel, and a discharge shaft is provided on the discharge shaft. The material shaft is rotated and the material is stirred, and the discharge motor is arranged on the cylinder body to drive the rotation of the material shaft, and the material guide hopper is arranged on the cylinder body.

Further, the bottom of the tank body is provided with a partition plate, which divides the tank body into an upper cavity and a lower cavity, and the partition plate is provided with a water barrier for the water in the upper cavity to penetrate into the lower cavity. In the permeable structure, the lower end of the stirring shaft is rotatably arranged on the partition plate. When the material is actually consumed in the tank, the condensed water in the steam in the tank is directly mixed with the solid material, which increases the moisture in the material, and the excess water can penetrate into the lower cavity through the supporting partition and pass through the discharge port Discharge, and control the moisture content of the material to ensure the stability of the material fermentation.

Further, in order to scrape and stir the material at the bottom of the tank and facilitate discharging, the bottom of the stirring shaft is provided with a scraper that rotates with the stirring shaft.
