Through setting up the spray chamber for the material in the casing has been kept away from in setting up of shower, has reduced blocking phenomenon's emergence, has improved the cleaning performance.

Preferably, the spray chamber is a cuboid shell with an open lower end, and the spray area is ensured on the premise of facilitating the arrangement of the spray pipe.

Preferably, the spray pipe is provided with a plurality of sections, and each section of the spray pipe is provided with a pipe joint respectively, so that the spray pressure of each part in the shell is ensured.

Preferably, the top surface of the spray chamber is respectively provided with a feed inlet, a vacuum interface and a steam port, so that the maximization of the setting area of the spray chamber above the shell is ensured.

Preferably, the heat medium half pipe comprises a straight pipe and a connecting pipe; the connecting pipe is arranged in a U shape; the two straight pipes are connected through a connecting pipe. The U-shaped arrangement ensures that the connecting pipe has less stress concentration after being welded with the straight pipe and is not easy to crack and leak.

Preferably, the straight pipe and the connecting pipe are respectively cast.

The utility model has the advantages as follows:

in the above scheme, the utility model provides a rake dryer, which comprises a base, a driving mechanism, a shell, a heating medium half pipe, a main shaft and rake teeth, wherein the shell is fixedly arranged on the base; a main shaft is coaxially arranged in the shell; the rake teeth are arranged on the main shaft; the main shaft is connected with a driving mechanism; the whole heat medium half pipe is attached to the outer wall of the shell in an S shape, and the heat medium half pipe also comprises a spray chamber and a spray pipe; the spray chamber is fixedly arranged at the upper end of the shell; the spray pipe is fixedly arranged in the spray chamber. Compared with the prior art, the dryer has the advantages that the spray chamber is arranged, so that the spray pipe is arranged to be far away from materials in the shell, the blocking phenomenon is reduced, and the cleaning effect is improved.
