Description

Technical Field

[0001] The utility model relates to the technical field of Liubao tea processing, in particular to a Liubao tea steaming processing device. Background Art

[0002] Steaming is one of the most critical steps in the processing of Liubao tea. In the ancient tea making method, because the amount of steaming is small at a time, the steaming step basically relies on the experience of the tea maker to control the maturity of the steaming. With the current industrialization, tea steaming machines are generally used. The existing tea steaming machines include a cylinder and a cylinder cover. A steam inlet is provided at the bottom of the cylinder. The tea leaves after preliminary processing are placed in the cylinder, and then the cylinder cover is covered. High-temperature steam evaporates from bottom to top to steam the tea leaves. However, in production practice, it is difficult to consistently control the maturity of the tea leaves in the entire cylinder using the existing tea steaming machines, because the cylinder cavity is a vertical cylindrical structure, and steam evaporates from bottom to top, so that the tea leaves at the bottom of the cylinder are already mature while the tea leaves on the upper layer are still in a half-raw state. To ensure that the tea leaves on the upper layer reach the required maturity, the tea leaves on the lower layer are already "overripe", resulting in inconsistent maturity of the tea leaves in the cylinder, which in turn affects the taste and quality of the entire batch of tea.
