Problems solved by technology

In this regard, it is necessary to spend a lot of labor to unblock and disassemble one by one before entering the next process
However, manual deblocking is difficult to achieve thoroughly. The dry tea products produced are often mixed with many untreated spherical and massive hard tea grains. Multiple screenings are required to ensure the purity of the dry tea.

[0030] 2. Preparation of Aspergillus oryzae and Rhizopus oryzae metabolic enzyme solution

[0031] According to the weight ratio of 86.7% of pure water, 8.3% of expanded soybean soaking juice, and 5.0% of brown sugar, heat and boil for 20 minutes, then cool to 30-40°C, add 0.5-1% of binary bacteria solid culture medium and mix, Sealed fermentation with natural pH at room temperature for 3-5 days, the bacterial liquid can produce a slight sweet distiller's grains smell, filter the beneficial bacterial culture liquid with fine gauze or sand net for 2-3 times, and store it cold in a fresh-keeping cabinet at 3-5°C until use , the active period lasts for half a year.

Embodiment 1

[0033] (1) Select the picked summer tea greens: pick the summer single buds that germinated in the same year, and the fresh tea greens should be protected from the hot sun, so that they are not picked on rainy days and the next day after rain; the length of the single buds during selection should not exceed 2.5cm, select the leaves and purple buds and leaves that have been damaged by diseases and insect pests.

[0034] (2) Withering adjustment: place the selected green tea green on the green bed, spread it thinly by 1.5-2.5cm thickness, and spread 4- After 8 hours, the buds and leaves are in a state of dehydration and wilting visually, and the water content of fresh green tea is 55-60%.

[0035] (3) Finishing: Choose an electric drum fixing machine with a diameter of 400mm and a length of 2000mm. Control the temperature at the inlet of the drum to 280°C, the temperature in the middle area to 180°C, and the temperature near the outlet to 120°C. The amount of leaves thrown is sm...

Embodiment 2

[0044] (1) Selecting the picked summer tea greens: pick the middle and small leaf summer tea greens with one bud and one leaf that have just unfolded in the same year. When selecting green leaves, the length of one bud and one leaf should not exceed 3cm, and the leaves and purple buds and leaves that have been damaged by diseases and insect pests should be selected.

[0045] (2) Withering adjustment: place the selected green tea green on the green bed, spread it thinly by 1.5-2.5cm thickness, and spread 4- 8h, the buds and leaves are dehydrated and shriveled visually, and the water content of fresh leaves is 55-60%.

[0046] (3) Finishing: Choose an electric drum fixing machine with a diameter of 400mm and a length of 2000mm. Control the temperature at the inlet of the drum to 280°C, the temperature in the middle area to 180°C, and the temperature near the outlet to 120°C. The amount of leaves thrown is small and uniform. , The feeding and discharging time is controlled withi...

Abstract

The invention relates to a method for preparing green tea from summer tea leaves. The method comprises the following steps of selecting picked summer tea leaves; withering the selected summer tea leaves; performing fixation on the withered summer tea leaves; spreading the summer tea leaves after fixation for cooling, lowering the temperature, and performing spraying with binary probiotic metabolism liquid of aspergillus oryzae and rhizopus oryzae; and rolling the summer tea leaves sprayed with the binary probiotic metabolism liquid, performing drying, and performing spreading for cooling, so as to obtain finished products of the green tea. According to the technical scheme provided by the invention, viscosity materials in the rolling process of the summer tea leaves can be notably reduced,regiment-shaped adhesive leaf balls or leaf blocks can be prevented, and the problems that the summer tea leaves are easy to break and difficult to shape during rolling and processing, and the dry tea is bitter, are solved. A microwave vacuum drying technique is combined, so that the dry tea products are light and grayish green in color, durable in fragrance, and clear in soup color. Through adoption of the method, the summer tea leaves are used as raw materials for making superior green tea.

Description

technical field [0001] The invention belongs to the technical field of tea making, and in particular relates to a method for making green tea from green tea in summer. Background technique [0002] In summer, the contents of cellulose, polyphenols and pectin in young leaves of Chaqing significantly increase with the rise of summer temperature and the continuous growth of buds and leaves, and the hardness of leaves also increases accordingly. Compared with tea greens in spring and autumn, green teas in summer are easily broken and difficult to form when kneaded. The dry tea strands are loose, dark green and dark in color, and bitter in taste. Therefore, green teas in summer are hardly used as raw materials for making green tea. Waste of precious natural resources. [0003] For example, according to the current processing method of domestic spring and autumn green tea, summer green tea is processed by kneading. The heat generated by the machine kneading of young green tea lea...
