[0002] Granulating kettle is a kind of equipment widely used in pharmaceutical, chemical, food and other industries. The working principle of granulating kettle is to mix powder, granules or liquid raw materials and form granules or solid particles through a certain processing method. These granules are usually used to make tablets, granules, granular condiments and other products.

[0003] The prior art has the following deficiencies: during the granulation process, high temperature may be generated in the granulation kettle, and the unloading rotary valve of the granulation kettle is just the place where the granulation material enters from the high temperature environment to the equipment or container with lower ambient temperature. When the material quickly enters from the high temperature environment to the lower temperature environment, crusting is likely to occur. The crusting of the material at the unloading rotary valve will cause the unloading port to be blocked and unable to unload the material. Therefore, it is necessary to manually use a rubber hammer to knock and vibrate the crust at the bonding rotary valve to crack the crust before the unloading work can be carried out normally, which is time-consuming and labor-intensive, and not only increases the labor cost, but also increases the unloading time of the granulation kettle, greatly affecting the production efficiency of the granulation kettle.
