Description

Technical Field

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

[0002] Tea refers to a beverage made from new leaves or buds of the tea tree, which have not been fermented, but have gone through processes such as withering, shaping and drying. Since ancient times, many people have liked to taste tea. Tea can be used as a beverage and contains many beneficial ingredients and has health benefits. In the production process of tea, there is a process called coloring, which is to dry and color the tea leaves to make the color of the tea brighter and also facilitate storage.

[0003] Existing tea coloring equipment generally uses a roller to drive the tea leaves to tumble and a heating fan to heat them at the same time. The rolling action of the coloring machine can make the tea leaves tighter, thereby improving the appearance of the tea leaves. During the coloring process, the color of the tea leaves will become greener and more frosty, that is, a layer of white fine crystals will appear on the surface, which makes the tea leaves look smoother and fresher.

[0004] There are two types of tea coloring: cold tea coloring and hot tea coloring. Cold tea coloring is a non-heating operation, which only makes the surface of the tea leaves smooth and improves the appearance. It is used for tea leaves that have been dried to ensure that the moisture content of the tea leaves remains unchanged. Hot tea coloring is carried out under heating. In addition to improving the appearance of the tea leaves, it also has a drying effect. It is suitable for tea leaves with a moisture content of more than 7%. It reduces the moisture content of the tea leaves, which is conducive to the long-term storage of the tea leaves and avoids mold and deterioration.

[0005] In the prior art, some hot and cold operations are performed in the same equipment, as different tea processing stages may require different temperature conditions. It may be difficult for the same equipment to accurately control the temperature when handling different tasks, which may affect the quality of the tea, and frequent switching of operating modes on the same equipment may accelerate the wear of the equipment. Especially during the heating and cooling process, mechanical parts may expand or contract due to the temperature difference, which may cause mechanical failure in the long run.
