Description

Technical Field

[0001] The utility model relates to a tea aroma-enhancing and impurity-removing roasting machine. Background Art

[0002] Tea leaf roasting is the last step in the tea making process. Its purpose is to evaporate the excess water in the tea leaves, promote the heating and aroma formation of the tea leaves, improve and fix the quality, and facilitate the storage of the tea leaves.

[0003] Traditional tea baking uses charcoal to bake, which removes the green taste of tea and gives the tea a charcoal aroma, which helps improve the taste and mouthfeel of tea. However, it is inefficient, requires high skills from the production staff, and has high production costs. Moreover, when baking tea in a charcoal oven, it is difficult to accurately control the temperature during the baking process, which can easily cause the temperature to be too high, resulting in over-baking of the tea. In addition, since the temperature is difficult to control during the charcoal baking process, the quality of tea produced in different batches will vary greatly.

[0004] Authorization announcement number CN215638577U discloses a tea roasting machine, including an oven, a drying chamber arranged in the oven, and an air supply device for supplying air to the oven, and also includes an air inlet channel for introducing the airflow of the air supply device into the oven, an air supply pipe connected to the air inlet channel, and a heating channel connected to the air supply pipe, the heating channel is provided with a heating device for heating the airflow, and is used to introduce the heated airflow into the drying chamber, the oven is provided with an air outlet, a return air channel is formed between the drying chamber and the air outlet, the airflow in the drying chamber flows out from the air outlet through the return air channel, and the air inlet pipe is arranged in the return air channel. It introduces the airflow of the air supply device into the oven through the air inlet channel, and introduces the airflow into the heating channel through the air supply pipe for heating, the heated airflow enters the drying chamber to roast the tea leaves, and the hot airflow after roasting is discharged from the return air channel and the air outlet, thereby reducing energy consumption and improving the utilization rate of the hot airflow energy, and reducing costs.

[0005] However, when in use, the tea leaves are stacked on a rotating rack in a drying room, and a heated air flow is introduced into the drying room to dry the tea leaves. The rotation of the rotating rack can achieve uniformity of the tea leaves to a certain extent. However, most of the heated air flow blows on the surface of the stacked tea leaves, and the tea leaves in the middle are difficult to contact with the heated air flow, and the formed steam is difficult to evaporate. Manual stirring is required at regular intervals, which not only reduces the efficiency but also causes a relative price difference in the baking quality. Utility Model Content
