Embodiment 1

[0018] A method for combining tea leaves, including the following steps:

[0019] (1) After washing the fresh leaves with clean water, bring water into the microwave oven and medium heat to quench until the water content drops to 55-60%;

[0020] (2) The tea leaves are spread on the storage trough, the thickness of the spread leaves is 10cm~15cm, the auxiliary blower is ventilated, and the spreading time is 10h;

[0021] (3) Tumbler curing: the tea leaves are processed in the first roller curing machine. The curing temperature is 230°C in the front and middle of the roller, 160°C in the rear, and the residence time of the tea is 7 minutes; the tea leaves after the initial curing are continuously transported to the first The two-roller curing machine emits heat and moisture on one side; the curing temperature in the second-roller curing machine: 200°C for the front and middle parts, 140°C for the rear part, and 3 minutes of tea stay time;

[0022] (4) Microwave supplementary killing: t...

Embodiment 2

[0026] A method for combining tea leaves, including the following steps:

[0027] (1) After washing the fresh leaves with clean water, bring water into the microwave oven and medium heat to quench until the water content drops to 55-60%;

[0028] (2) The tea leaves are spread on the storage trough, the thickness of the spread leaves is 10cm~15cm, the auxiliary blower is ventilated, and the spreading time is 14h;

[0029] (3) Tumbler curing: the tea leaves are processed in the first roller curing machine. The curing temperature is 280℃ in the front and middle part of the drum and 180℃ in the rear part. The residence time of the tea leaves is 5 minutes; The two-roller curing machine emits heat and moisture on one side; the curing temperature in the second-roller curing machine: 180°C for the front and middle part, 120°C for the rear part, and the tea stay time is 4 minutes;

[0030] (4) Microwave supplementary killing: the tea leaves after being cured by the drum are sent to the microwa...

Abstract

The invention discloses a combined green-fixing method of tea leaves. The method comprises the steps of fresh leaf washing and draining, spreading, green-fixing in a cylinder, remedial green-fixing with microwave, rolling, tea strip tidying, drying and the like. According to the method, green-fixing is performed on tea leaves which are subjected to primary treatment including green leaf storage and other processes, two-stage cylinder green-fixing is utilized in the green-fixing process, humid and hot air is emitted during continuous delivery between the two cylinders, so that the problem thata great number of tea leaves are yellow and have red stalks or leaves due to the fact that humid air in the cylinder is difficult to emit and green-fixing is not performed sufficiently can be avoided;and remedial green-fixing with microwave can be used for quickly destroying and passivating the activity of oxidase in fresh leaves and inhibiting enzymatic oxidation of tea polyphenol and the like.The method can solve the problems of uneven green-fixing and poor green-fixing effect in an existing tea leaf green-fixing method, and ensures the taste and flavor of tea leaves.

Description

Technical field [0001] The invention relates to a tea processing technology, in particular to a combined method for curing tea. Background technique [0002] Tea is a traditional drink that people love, especially green tea, because it maintains a bright green appearance and color and natural nutrients, it is especially popular in the market. The finishing process is an important step in its processing and a key step in the formation and improvement of tea quality. [0003] The existing batch-produced tea leaves are made with a finishing process: the fresh tea leaves are graded, spread, and then finished with a roller finishing machine. The process can basically adapt to production, but it also has the following defects: it is prone to impermeability and unevenness, and the phenomenon of tea burnt edges, burnt leaves, red stems, and red leaves often occurs. The quality of the green stir-fried green produced is consistent with traditional handwork. There is a clear gap in the qual...
