In this embodiment, two set up a conveyer belt that goes to the fodder agitator tank between the stand 101, after guaranteeing that the fermentation raw materials makes, can mix immediately, pelletize, and rotatory cylinder 202 need with outside gear motor drive, also set up the gear on it, guarantee rotatory cylinder 202 is taken together cylinder frame body unit 4 can rotate with fixed controlledly, avoids cylinder frame body unit 4 accident emptys.

The upper half fixed pan body unit 3 comprises an arc-shaped ring 301 which is arranged on the transverse fixing plate 102 and has a large upper part and a small lower part, and a stirring motor mounting plate 302 arranged on the arc-shaped ring 301; the lower half lifting pot body unit 5 comprises an arc-shaped lifting chassis 501 which is used for upwards butting the arc-shaped circular ring 301.

In this embodiment, the existing common stir-fry structure is installed on the stirring motor mounting plate 302, including the circumferential stir-fry and the up-down stir-fry, and the arc lifting chassis 501 has a smaller diameter and a shallower depth compared with the whole pan body.

The cylinder frame body unit 4 includes a cylinder body 401 disposed on the rotating plate 203, a circular plate 402 disposed on the cylinder body 401, and a guard ring 403 disposed on an outer circumferential surface of the circular plate 402 and having a small top and a large bottom, and used for mounting the arc-shaped lifting chassis 501 and performing a blanking protection on the cylinder body 401.

In this embodiment, the guard ring 403 is fixedly connected to the lower surface of the arc-shaped lifting chassis 501, and the rotating plate 203 may be provided with an air pump, a power supply and a unit required by a heating structure, which are all located in a vertical annular region of the guard ring 403, so as to prevent falling materials from falling on any electromechanical component.

In addition, the arc-shaped lifting chassis 501 needs to be separated from the arc-shaped ring 301, so the lower part of the heat conducting oil 304 needs to be sealed, and the sealing structure also needs to allow the heat conducting plate 502 to be inserted, so the annular sealing film 305 with a proper width dimension is arranged, and the insertion depth of the heat conducting plate 502 is ensured to be properly large.

The annular sealing film 305 is made of a conventional resin film, but has a relatively small thickness, although the heat conductivity is not as good as that of a metal, and therefore, the heat conductivity is sufficient, and the heat conductive plate 502 is made of a metal having a higher heat conductivity, such as copper.

The cylinder block unit 4 further includes a wire guide hole 407 provided on the circular plate 402; the upper half fixed pan body unit 3 further comprises an elastic sealing ring 306 arranged on the lower surface of the arc-shaped ring 301; the lower half lifting pot body unit 5 further comprises a thickness reducing slot 503 which is arranged on the lower surface of the arc-shaped lifting chassis 501 and is positioned in the protective ring 403.

In addition, the elastic sealing ring 306 is located inside the heat conducting plate 502 to ensure that the powdery material is properly prevented from falling down from the butt joint gap in a large amount, and the material is common rubber, which has no problem at least for the material temperature requirement of 80-95 ℃.

Finally, the function of the groove 503 for reducing thickness is to make the electric heating plate 406 closer to the heat conducting plate 502, so as to improve the heat conducting capability, the electric heating plate 406 and the heat conducting oil 304 can be properly close to the center of the pot body, and the outer annular surfaces of the arc-shaped ring 301 and the arc-shaped lifting chassis 501 are coated with heat insulating coatings.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
