Problems solved by technology

[0003] However, the current production process is complicated, the degree of mechanization is not high, the output is low, and the quality is poor
Especially when using a ball mill for grinding, the amount of tea that can be loaded into the ball mill is limited each time, and the ball mill needs to be opened frequently for loading and unloading. In addition, when the ratio of the size of the ball to the material is within an appropriate range, the grinding efficiency will be very high. High, as the material becomes smaller, the grinding efficiency will decrease. In addition, the presence of finer tea powder will also affect the crushing effect of the grinding ball on larger tea leaves, resulting in a decrease in grinding efficiency.

Embodiment 1

[0022] A method for producing superfine green tea powder, comprising the following steps:

[0023] Green storage: put the green leaves into the green storage tank for storage;

[0024] Greening: the green leaves are steamed with 100°C saturated steam, and the degree of greening is controlled according to the characteristics of the product;

[0025] Cooling: Cooling the leaves after steaming, for example, cooling the leaves after steaming and removing surface moisture in the form of a cooling net;

[0026] Drying: The green leaves are dried in four layers, the upper and lower layers are about 120-200°C, and the middle is 90-150°C; Separation of stalks and leaves: remove the remaining stalks in Tencha, and remove them at the same time stones, impurities, etc.;

[0027] Secondary drying: The leaves of the tea leaves separated by the stem-leaf separator are subjected to secondary drying to control the moisture of the tea leaves, ensure the quality and facilitate storage.

Abstract

The invention discloses a production method of ultramicro green tea powder. New fresh and tender tea leaves in the current year are used as a raw material. The method comprises the following steps: performing green leaf storing, fixation, cooling and drying, and separating leaves from tea stems by using a stem-leaf separator; and carrying out secondary drying, secondary stem-leaf separation, ball-milling crushing and mechanical grinding, and sieving ground tea powder to obtain a tea powder meeting the specification fineness. The tea powder disclosed by the invention is simple in production method, green and uniform in color and luster, fragrant in smell, small in fineness and free of metal components, and the obtained tea powder is used for making matcha products which are fresh in taste.

Description

technical field [0001] The invention relates to the technical field of tea powder processing, in particular to a production method of ultrafine green tea powder. Background technique [0002] The characteristics of tea powder are fragrance, elegant, ultra-fine; high content of protein, amino acid and chlorophyll; low content of tea polyphenols and caffeine. It has no additives, no preservatives, and no artificial coloring. It can be suspended in hot water without precipitation and presents a bright green tea soup. Dissolves in water like coffee. Taking into account the advantages of drinking tea and eating tea, it is a kind of best green tea. [0003] However, the current production process is complicated, the degree of mechanization is not high, the output is low, and the quality is poor. Especially when using a ball mill for grinding, the amount of tea that can be loaded into the ball mill is limited each time, and the ball mill needs to be opened frequently for loading...
