Description
Technical Field
[0001] The utility model relates to the technical field of baking, in particular to a crushed cigarette baking machine. Background Art
[0002] In the re-baking process, the process of baking the broken tobacco slices is to use hot air to bake the tobacco slices. The heating baking of the broken tobacco in the original broken tobacco re-baking equipment adopts a rotating baking tube that rotates 360° around the cylinder. In the actual baking process, it is found that the sealing of the baking tube rotary joint decreases after long-term operation. The rotary joint is inside the baking machine cylinder. When the sealing decreases, there is a risk of dripping, and the internal dripping is hidden and difficult to find, which easily causes wet fragments to mix into the finished product, affecting the quality of the finished product. Damage to the rotary joint will also cause steam leakage from the baking tube, causing abnormal temperature in the cylinder, which will make it difficult to control the moisture content of the broken tobacco and affect the product qualification rate. On the other hand, the rotary joint is expensive and the replacement cost is high. As a consumable part, it greatly increases the production cost. In addition, the replacement steps of the rotary joint are cumbersome, and the downtime maintenance takes a long time. Frequent maintenance affects production efficiency. In view of this problem, the utility model provides a broken tobacco baking machine, which uses a stationary baking tube to bake the broken tobacco, effectively avoiding the problem of reduced sealing during the use of the rotary joint.
