In the prior art, the three-layer tea leaves are boxed and steamed at the same time. In order to meet the steaming requirements of the middle tea, the steaming time of noodle tea is too long, resulting in high water content and too soft tea raw materials, which is not conducive to later pressing and baking. Drying process, therefore, it is necessary to select different steaming systems for different raw materials of face tea and inner tea, including control of steaming time and steam volume.

Moreover, the three layers of tea leaves are stacked in sequence and put into the same tea box for steaming. Since the upper tea is far away from the position where the steam is emitted, and there is isolation between the bottom tea and the middle tea, the steaming effect cannot meet the requirements. , while the bottom tea of the same raw material is closer to the position where the steam is emitted, and the steaming is transitional. The middle tea between the bottom tea and the top tea needs a longer steaming time, in order to prevent the bottom tea from being damaged by steam for too long However, the middle tea cannot meet the steaming requirements. In a word, according to the existing method, the steaming effect of the three-layer tea leaves cannot be taken into account, which affects the quality of brick tea and the follow-up process.

The existing tea steaming production line adopts a long assembly line, which occupies a large area, and it is difficult for staff to monitor and manage abnormal conditions.
