[0002] Tobacco baking is an important step in the tobacco processing process. When tobacco baking is carried out, it is usually carried out on a corresponding tobacco baking machine. This type of tobacco baking machine has a heating function and can complete a better baking operation. In addition, since the baking temperature has an important influence on the quality and taste of tobacco, traditional tobacco baking machines often use fixed temperature settings and cannot accurately adjust the temperature according to factors such as the type, humidity and baking stage of tobacco, resulting in unstable baking effects and uneven tobacco quality, which affects the baking effect.

[0003] At present, tobacco baking machines on the market can overcome the above defects when in use. Such tobacco baking machines are usually provided with a temperature regulating mechanism, which can be used to control the current temperature and achieve the effect of precise temperature control for baking.
