Abstract

The invention provides a process for processing green tea by a microwave moisture-removing method. The process comprises the following steps: (1) washing fresh tea leaves, and spreading in a shady andcool place until no water stain exists on the tea leaves; (2) removing moisture from the aired tea leaves in a microwave oven; (3) cooling the moisture-removed tea leaves in the step (2) for cooling,rolling with a micro-roller for 10 minutes according to a light-heavy-light pressing method; (4) drying the tea leaves treated in the step (3) in a drying tank in three steps, namely adjusting the temperature of the drying tank to 90-102 DEG C and drying for 60-80 minutes in the first step, adjusting the temperature of the drying tank to 75-85 DEG C and drying for 95-120 minutes in the second step, and closing the drying tank, introducing nitrogen at normal temperature and naturally cooling the tea leaves to obtain a finished product in the third step. According to the process, enzyme insidethe tea leaves can be completely inactivated, beneficial substances inside the tea leaves cannot be broken, and the tea leaves have an excellent taste.

Description

technical field [0001] The invention relates to a tea processing technology, in particular to a green tea processing technology by a microwave fixing method. Background technique [0002] Greening of tea leaves means that the moisture inside the tea leaves is discharged by heating. During the whole process, the color of the tea leaves changes from fresh green to burnt yellow, so this process is also called greening. The traditional greening technology is frying, which uses firewood to heat an iron pot or an electric casserole, and uses manpower to turn the tea leaves to improve the uniformity of the tea heat. This method of killing greens is likely to cause problems such as red stalks and red leaves, yellow stew, and uneven killing due to inaccurate fire control, and it is easy to form burnt leaves, which further presents a relatively high fire flavor in the taste and affects the quality of the tea. Contents of the invention [0003] Aiming at the deficiencies in the prio...
