Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a spiral single-cone drying mixer. Background Art

[0002] A single cone dryer is a mechanical device that uses heat energy to reduce the moisture content of materials. It is indirectly heated by the heat medium in the jacket of the dryer body. The spiral belt rotates forward and reversely to continuously turn the dried material to update the drying surface, so that the moisture in the material is vaporized and escapes, thereby achieving the purpose of drying the material. The existing single cone dryer is composed of a shell, a driving mechanism, a stirring component and a discharge valve. However, in the prior art, the stirring component of the single cone dryer is often vertical. For solids such as smoothies, the efficiency of lifting materials during the drying process is poor. After a long drying time, a considerable portion of the material will still accumulate in the dead corners of the stirring component after cleaning, which is prone to material residue problems.

[0009] By adopting the above technical solution, the first mounting groove and the third mounting groove are used to form a pair that can support and fix the first rotating rod and the third rotating rod. At the same time, the second mounting groove is used to stabilize the second rotating rod when it rotates, preventing the second rotating rod from shaking during operation.

[0012] The utility model is further configured such that the shell is configured in a conical shape, and the shell is gradually reduced toward the pressure relief valve side.

[0013] By adopting the above technical solution, the conical shell can achieve a drainage effect during cleaning work, thereby improving the cleaning efficiency.

[0014] The utility model is further configured such that the second rotating rod and the first bevel gear and the second bevel gear are an integrated structure.

[0015] By adopting the above technical solution, the stability and firmness of the overall structure are enhanced. Different from the separate structure, the connection of the integrated structure will not loosen, avoiding the problem of separation of the second rotating rod from the first bevel gear and the second bevel gear during rotation.

[0016] The utility model is further configured such that the second rotating rod is arranged in an orthogonal state to the first rotating rod.

[0017] By adopting the above technical solution, the transmission effect of the rotational force is more stable, and the pressure of the connection end between the second rotation rod and the first rotation rod is relatively small, so the rotational force is transmitted more easily.
