Description

Technical Field

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

[0002] Stir-frying tea is a type of withering, also known as frying green tea. Its main purpose is to inhibit the enzymatic oxidation of tea polyphenols in the fresh leaves by destroying and passivating the oxidase activity in the fresh leaves through high temperature, evaporate part of the moisture in the fresh leaves, soften the tea leaves, and facilitate rolling and shaping. At the same time, it emits a green smell and promotes the formation of a good aroma.

[0003] Existing industrial tea frying generally uses a frying dryer, which pours tea leaves into the machine and rotates and stirs the tea leaves to evaporate the water vapor inside the tea leaves. The existing frying dryer directly discharges the water vapor out of the device, resulting in a waste of heat inside the water vapor. At the same time, the existing frying dryer will continue to supply gas at normal temperature into the machine, which requires the frying dryer to consume additional energy to reheat the new gas entering the device, thereby increasing the cost of tea frying.
