Description

TECHNICAL FIELD

[0001] The utility model relates to tea processing equipment field, especially a kind of suitable for tea processing use fixation device. BACKGROUND

[0002] Green tea is one of the main tea classes in China, which refers to the new leaves or buds of tea trees, without fermentation, through fixation, shaping, drying and other processes to make a beverage. The color of its finished product and the tea soup after brewing mostly retains the green style of fresh tea leaves. Regularly drinking green tea can prevent cancer, reduce fat and lose weight, and also reduce the harm of nicotine to smokers.

[0003] Green tea fixation is a key process in green tea processing, which takes high-temperature measures to release moisture in the leaves, inactivate enzymes and cause certain chemical changes in the contents of fresh leaves, thereby forming the quality characteristics of green tea. During fixation, if the pan temperature is too low and the leaf temperature rises for too long, it will cause enzymatic reaction of tea polyphenols, resulting in "red stem and red leaves". On the contrary, if the temperature is too high, chlorophyll is destroyed more, resulting in yellow leaf color, and some even produce burnt edges and spots, reducing the quality of green tea.

[0004] When fixing green tea, the tea leaves need to be placed in a fixation cylinder first. The fixation cylinder is provided with a stirring device, and the stirring device is provided with a rotating plate for stirring tea leaves, which facilitates the loosening of accumulated tea leaves and is beneficial to the fixation of tea leaves. However, during the fixation process, manual observation of the current state of the tea leaves is required to facilitate quick separation from the fixation machine after fixation is completed, so as to avoid overlong frying time caused by high temperature in the barrel wall, which leads to tea paste.

[0005] Chinese utility model patent (authorized announcement number: CN222357186U, name: a tea leaf fixation device for green tea production) relates to the field of tea leaf fixation device. The tea leaf fixation device for green tea production includes a rotating device, a placing rack installed on the rotating end of the rotating device, a fixation cylinder rotatably connected to the placing rack, a driving device fixedly installed on one side of the placing rack, a stirring device for tea fixation installed on the fixation cylinder, an inclined block fixedly installed on one side of the bottom of the fixation cylinder, a sliding groove provided at the bottom of the inclined block, and the top end of the driving device is arranged in the sliding groove. The driving device drives the fixation cylinder to reciprocate through the inclined block. The tea leaf fixation device for green tea production provided by the utility model enables the tea leaves in the fixation cylinder to move in multiple directions, which to some extent, accelerates the fixation effect of the tea leaves. However, the frying process needs to be stopped for sampling, and after stopping, some tea leaves will be overheated, which will affect the uniformity of the product and the overall quality. SUMMARY
