Description

Technical Field

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

[0002] Tea leaves, commonly known as tea, generally include leaves and buds of tea trees. After the tea leaves are picked, they need to be processed before use. Modern tea-making technology can be roughly divided into six basic processes: fresh leaf processing, killing green leaves, withering, rolling, fermentation, and drying. Among them, fermentation equipment is usually used to operate the tea leaves in order to save labor costs.

[0003] In the process of fermenting tea leaves, a fermentation device is usually used, such as a tea fermentation device with patent application number CN202222750664.2, which includes a body, the top of which is fixedly connected with a water pump, a water tank, a cover body and a hot air blower from left to right, a driving motor is fixedly connected to the inner wall of one side of the cover body, and a worm is fixedly connected to the output shaft of the driving motor. The utility model has the following advantages and effects: through the setting of the rotating placement box and the stirring rod, not only the rotation of the tea leaves is driven, but also the tea leaves in the placement box can be stir-fried, and then the rotating tea leaves can be evenly humidified and heated, thereby ensuring the quality of tea fermentation.

[0004] The deficiencies of the prior art are explained as follows: However, when the above-mentioned equipment is used to stir the tea leaves, the rotation of the internal stirring rod can stir-fry the tea leaves in the placement box, further improving the uniformity of tea humidification and heating, and ensuring the quality of tea fermentation. When used in this scenario, the stirring rod and the placement box will rotate in the same direction. When the tea leaves are stirred, the tea leaves in contact with the stirring rod will be stirred, but the stirring effect of the tea leaves that are not in contact with the bottom wall of the placement box and the stirring rod will be much reduced, or even unable to be stirred, resulting in the tea leaves always remaining at the bottom of the placement box during the fermentation process and unable to come into contact with clean water, affecting the fermentation effect, and in severe cases, carbonization will occur.
