Description

Technical Field

[0002] The tobacco production process involves many links such as picking, cleaning, drying, and roasting of fresh leaves. Among them, drying uses a drying can. A temperature sensor is installed inside the drying can to control temperature changes and ensure the constant temperature inside the drying can. The temperature sensor is generally fixed inside the drying can by screws. When it fails, the can cover needs to be opened for maintenance. In order to ensure the sealing and firmness of the drying can, the can cover is generally fixed at multiple points. Opening and closing requires each fixed point to be operated one by one, which takes a lot of time and affects the maintenance efficiency of the temperature sensor. At the same time, since the temperature sensor is fixed inside the drying can by screws, the installation and removal of the temperature sensor inside the drying can is limited by its internal space, making the operation more inconvenient, resulting in low installation and removal efficiency of the temperature sensor, which also affects the maintenance efficiency of the temperature sensor.
