Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco leaf baking, and in particular relates to a tobacco leaf baking yellow-stem rack color observation device. Background Art

[0002] Tobacco leaf baking is an extremely important part of the current flue-cured tobacco production. The three-stage baking process is divided into three stages, namely the yellowing stage, the color fixing stage, and the dry tendon stage. During baking, tobacco leaves are prone to baking green, baking red, and hanging ash, resulting in aroma and fragrance volume that are difficult to meet the raw material requirements of "Chinese cigarettes". Therefore, in order to prevent tobacco leaf baking failure, staff are required to frequently enter and exit the tobacco leaf baking room to check the tobacco leaf baking conditions. The manual color observation method is labor-intensive and has a large number of factors that affect the flue-cured tobacco production efficiency and product quality, so it is necessary to make improvements.

A heat dissipation device is used to prevent the color observing device from being damaged by a stuffy environment. The weighing support device can be used to grasp the weight change information caused by dehydration of the tobacco leaves in real time, thereby providing conditions for controlling the moisture content of the tobacco leaves. The utility model has a simple structure and a reasonable design. While ensuring stable operation of the color observing device, the working efficiency is improved, the service life of the observation device is increased, and the utility model has a high use value.
