Description

Technical Field

[0002] In modern life and industrial production, it is often necessary to use a dryer to dehydrate some water-containing substances, including food dehydration, material dehydration, etc. During the drying process of the dryer, heating treatment is required for dehydration, but some substances will also produce some gases after being heated, including harmful gases and malodorous gases. When the existing dryer uses a closed gas cycle to perform heat treatment in the dryer, due to the problem of local positive pressure and air leakage due to poor sealing, some harmful gases and malodorous gases with peculiar smell will be continuously discharged from the dryer, causing harm to the surrounding environment and workers.

[0003] Therefore, how to deal with the odor generated by the dryer is a technical problem that needs to be solved. Utility Model Content
