Description

TECHNICAL FIELD

[0001] The utility model relates to tea processing technical field, concretely is a tea baking aroma machine. BACKGROUND

[0002] With the continuous development of society, the types of tea are also more and more, some become local specialties, and tea also has very many components that are beneficial to human health, and many people have developed the habit of drinking tea. No matter how the society develops or how many types of tea there are, good tea can only be recognized by consumers and can only be popularized in more areas. The taste of tea determines the good or bad taste of the tea, so the tea aroma of the tea leaves needs to be preserved during tea production to improve the taste of the tea. The common aroma extraction method is baking.

[0003] After searching, the Chinese patent with publication number CN221284520U discloses a tea baking aroma machine, which comprises a box-shaped machine body, a layer-by-layer arranged material containing assembly is arranged in the box-shaped machine body, the material containing assembly comprises a row of first support rods and a row of second support rods, and a tea containing net is arranged above the first support rods and the second support rods, the first support rods and the second support rods are alternately and intermittently distributed, and the first support rods and the second support rods are located at different heights, and the tea containing net is in a wave shape; the first support rods and the second support rods are connected with a driving mechanism.

[0004] When the device is in use, the tea on the tea containing net can be turned over through the alternating and intermittent conversion of the wave crests and troughs of the tea containing net. The turning mechanism does not contact the tea, thereby effectively avoiding damage to the tea caused by the turning mechanism.

[0005] However, the device still has the following problems. The device drives the first support rods and the second support rods to alternately fluctuate through the driving mechanism, so that the wave crests and troughs of the tea containing net are alternately and intermittently converted, thereby turning over the tea. In actual use, the tea is relatively dry in the later stage of baking, and the friction between the mesh of the tea containing net and the tea and between the tea and the tea will still cause the tea to break into small pieces. Subsequent screening of small tea fragments is difficult to effectively improve the comprehensive utilization rate of the device for tea processing. UTILITY MODEL CONTENTS
