Description

Technical Field

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

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea tree. The ingredients of tea include catechins, cholestenone, caffeine, inositol, folic acid, and pantothenic acid, which are good for health. Tea beverages made from tea leaves are one of the three major beverages in the world. Tea originated in China, and tea was first used as a sacrifice.

[0003] A tea drying machine provided in the Chinese utility model patent application disclosure specification CN218571310U includes an outer frame, a feeding port is fixedly arranged at the top center of the outer frame, a guide plate is fixedly arranged at the lower part of the inner wall of the feeding port, a stirring assembly is movably installed in the inner cavity of the outer frame, an air inlet pipe is rotatably connected to the end of the stirring assembly, a connecting pipe is fixedly connected to the end of the air inlet pipe, a hot air blower is fixed to the end of the connecting pipe, and the hot air blower is fixed to the outer frame, and a circulation assembly is connected to the top of the outer frame. In a tea drying machine, during the drying process, the user can start the negative pressure fan to suck water vapor into the circulation pipe, and finally the water vapor is subjected to the moisture absorption treatment of the moisture absorption tank, and the dry hot air is then introduced into the machine by the circulation pipe for recycling. Through the setting of the circulation assembly, the heat in the water vapor can be recycled, thereby improving the thermal efficiency of the machine and saving energy. However, the device uses the lever of the stirring assembly to flip the tea leaves, and the tea leaves are easily broken by the lever during the tea drying process, which affects the quality of the tea leaves. Therefore, a tea drying machine is urgently needed. Utility Model Content
