Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a tea frying device for improving the quality of tea. Background Art

[0002] Frying tea is an important step in the tea making process. The purpose of frying tea is to accelerate the evaporation of water in the tea leaves, thereby blocking the fermentation of the tea leaves. One of the most important issues in frying tea leaves is how to control the temperature of frying tea, preventing the tea leaves from being burnt while ensuring that the tea leaves are heated evenly, so that the fried tea leaves have better quality.

[0003] After searching, it was found that the publication number is CN111713570B, and the name is a multi-position stirring tea frying equipment with uniform heating. The patent announcement number of this application is: CN207692884U. The patent discloses a tea frying device. Due to the limitation of the swing range of the clay pot, it is impossible to stir-fry a large amount of tea at one time, the tea frying efficiency is low, and only the bottom of the clay pot can be heated, and it is still impossible to achieve sufficient and uniform heating and frying of the tea. The large heating rack and the small heating rack work together to heat and stir-fry tea leaves at different heights and different layers of the open rotating frame. The stir-frying process of a large amount of tea leaves can be completed relatively quickly, thereby improving the stir-frying efficiency of the tea leaves. At the same time, the stirring rod is driven to rotate by the open rotating frame, so that the tea leaves can be continuously stirred during the stir-frying process, so that the position of the tea leaves in the open rotating frame can be continuously changed, thereby allowing a large amount of tea leaves to be heated more evenly and comprehensively. However, although the application can achieve the effect of uniform stir-frying, its structure is very complicated, and the stirring rod in contact with the tea leaves stirs the tea leaves rigidly, and the stirring is too frequent, which can easily damage the integrity of the tea leaves in the case of excessive stirring, affecting the bud shape, thereby affecting the appearance of the tea leaves and affecting the quality of the tea leaves.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
