Embodiment 1

[0023] For the processing of Longjing, the raw materials of one bud and one leaf are put into the roller degreening machine 1 for degreening, and the decapitation time is about 3 minutes. , It is recommended to use microwave energy above 100KW 2450MHZ. The high power density microwave heating equipment is preferably customized into a vertical cylinder shape. , rapid cooling until normal temperature, freezing using a general-purpose freezer, preferably custom-made minus 10 degrees, and preparing a freezer with a micro-fan in the freezing space; the cooled tea leaves are fried by hand using known techniques, and finally refired until they are dry enough.

[0024] According to the evaluation of the produced products, the color of the dry tea is yellow-green, the color of the leaves is light green, the burnt aroma is obvious, and the tea soup is rich and delicious, which is obviously stronger than the tea processed by traditional techniques.

Embodiment 2

[0026] For the processing of Biluochun, the raw materials of one bud and one leaf are put into the roller degreening machine 1 for degreening, and the decapitation time is about 3 minutes. , It is recommended to use microwave energy above 100KW 2450MHZ. The high power density microwave heating equipment is preferably customized into a vertical cylinder shape. , quickly cool down to normal temperature, and use a general-purpose freezer for freezing, preferably a custom-made freezer at minus 20 degrees, and prepare a freezer with a micro fan in the freezing space; the cooled tea leaves are kneaded on a kneading machine, and then placed in an electric frying pan when the time is reached for rubbing Manually rub the snails to lift the hair, and finally dry it in the dryer until it is fully dry.

[0027] The tea leaves made by traditional crafts were used as a comparison, and the evaluation and comparison of tea were carried out. It was found that there was no difference in the col...

Embodiment 3

[0029] For the processing of high-grade tea, put the single bud or one bud and one leaf raw material into the roller degreening machine 1 for degreening, the decapitation time is about 3 minutes, and the degree of decapitation is controlled according to the heat degree slightly higher than the known; the decapitated leaves are then put into the high power density microwave equipment 2. For cell cracking, it is recommended to use microwave energy above 100KW and 2450MHZ. The high-power-density microwave heating equipment is preferably customized as a vertical cylinder. Fall into the freezing space 3, quickly cool down to normal temperature, and use a general-purpose freezer for freezing, preferably a custom-made freezer at minus 20 degrees, and prepare a freezer with a micro fan in the freezing space; the cooled tea leaves are sorted on the slitting machine to reach the plodding time After pressing the stick for about 10 minutes, take it out of the pan, let it cool for half an h...

Abstract

The invention discloses a method for processing mellow-thick green tea, and relates to a tea processing method. The method aims at achieving the aim that on the basis of keeping the quality of traditional tea, the concentration of tea soup of upscale green tea is increased. The processing method includes the following steps that fresh leaves are fixed through a fixing machine, then tissue cracking is conducted through microwaves, the cracked tea is quickly frozen and cooled, the quickly-frozen tea is shaped, and finally refiring is carried out till the tea is adequately dry. The method has the advantages that the fixed leaves are heated through the high-power-density microwaves, moisture contained in cells of the fixed leaves is rapidly heated and gasified, cell walls are broken through gasifying, tea cell contents can be conveniently dissolved out during brewing, and therefore the effect of increasing the concentration of the tea soup is achieved.

Description

technical field [0001] The invention relates to a tea processing method, in particular to a high-grade green tea processing method. Background technique [0002] With the improvement of people's living standards, the demand for high-grade green tea has increased significantly. The traditional high-grade green tea processing still uses the processing method of bulk green tea, but the amount of leaves is less, more handwork is added, and the production is finer. It is a simple transformation of the traditional tea-making process without substantial changes. For example, in Longjing, the greens are first finished on a micro-finishing machine, then shaped by hand, and finally dried. Because the high-grade green tea raw materials are delicate and there is no process of breaking the cell structure, the tea produced has a weak taste and insufficient concentration. Contents of the invention [0003] The technical problem to be solved by the invention is to increase the concentra...
