The dry hot air formed after the secondary heating enters the top of the drying tower, and the dry hot air flows downstream with the material. The dry hot air instantly heats and dehydrates the mash. Part of the hot air containing protein powder enters the cyclone separator and the bag dust collector from the air outlet of the drying tower for secondary capture of the protein powder. The generated exhaust gas is led by the induced draft fan to the deodorization system and discharged into the atmosphere after meeting the standards.

The end of the spraying pipeline is connected to 10 spray guns, through which the spraying is carried out. The spraying pipeline is also connected to a cleaning water tank, which provides cleaning water for the spraying pipeline. When the spraying stops, the cleaning water is introduced to flush the spray gun. Generally speaking, the production water at the production site is used as cleaning water.

[0040] Please refer to Figure 4 and Figure 5 The present application provides a protein drying tower, including a tower body, a plurality of spray guns 1, a spray pipeline 2 and a plurality of booster flow stabilizing cylinders 3. The plurality of spray guns 1 are installed on the top of the tower body, the spray pipeline 2 is connected to the plurality of spray guns 1, the spray pipeline 2 includes a main pipe 21 and a plurality of branch pipes 22, the plurality of branch pipes 22 are all connected to the main pipe 21, the plurality of branch pipes 22 are respectively connected to the plurality of spray guns 1, the spray gun 1 is located at one end of the branch pipe 22 away from the main pipe 21, and the mash is transported to the spray gun 1 through the spray pipeline 2. Please refer to Figure 6 A plurality of boosting and stabilizing flow cylinders 3 are provided with a cylinder cavity, and a cylinder mouth is formed at the end face of the boosting and stabilizing flow cylinders 3.
