Technical Field

The invention relates to the technical field of tea processing, in particular to an intelligent constant-temperature fixation device for tea processing.

Background

The method is a tea making step which destroys and passivates the activity of oxidase in fresh tea leaves at high temperature, inhibits the enzymatic oxidation of tea polyphenol and the like in the fresh tea leaves, evaporates partial water of the fresh tea leaves, softens the tea leaves, is convenient for rolling and shaping, simultaneously disperses green odor and promotes the formation of good aroma.

The fixation is one of the primary processing procedures of green tea, yellow tea, black tea, oolong tea and the like.

The fixation is a key process for forming the shape and quality of green tea and the like. A water-removing mode: parching, steaming, baking, soaking, and deactivating enzyme by radiation. Steaming Tang dynasties is commonly used, and Japan, Russia and India are more applied. The pan-frying method is popularized in the back of Mingdu in China and is commonly used by various tea producing countries in the world. The high-temperature fixation is generally mastered, namely the fixation is performed firstly and then is performed secondly; tender and tender old leaves; and the principle of throwing and stuffiness combining, throwing more and throwing less stuffiness and the like. Steaming green is carried out at high temperature and quickly.

And after the fresh leaves are picked, spreading and drying the fresh leaves on the ground for 2-3 hours, and then carrying out enzyme deactivation.

The existing tea leaf fixation device is difficult to ensure constant internal temperature, adverse effects are caused to the quality of tea leaves, and when the fixation temperature is too high, the leaves are easy to be burnt, which is one of the main reasons that some tea leaves are heavy in smoke smell and more in broken powder; meanwhile, chlorophyll is damaged more, and the leaf color is yellowed; the content of caffeine, theanine, soluble sugar and the like is reduced, so that the quality of the tea leaves is changed. The low temperature easily leads to the insufficient enzyme deactivation, easily causes red peduncle and red leaves, the finished tea has green taste and even sour taste, the low temperature and the overlong enzyme deactivation time can lead the tea to become dark and black in the enzyme deactivation pot, therefore, the accurate control of the temperature is the premise of ensuring the quality of the enzyme deactivation leaves.

And the prior tea leaf enzyme deactivating device is inconvenient for discharging and has adverse effect on production efficiency.
