Embodiment 1

[0026] When puffing, put the granular green tea in the puffing machine, control the temperature at 50°C, the pressure at 0.2MPa, and keep it for 5min; Lower the temperature to -10°C and hold for 5 minutes.

Embodiment 2

[0028] When puffing, put the granular green tea in the puffing machine, control the temperature at 65°C, the pressure at 0.3MPa, and keep it for 15min; Lower the temperature to -3°C and keep for 15 minutes.

Embodiment 3

[0030] When puffing, put the granular green tea in the puffing machine, control the temperature at 80°C, the pressure at 0.4MPa, and keep it for 25min; Lower the temperature to 4°C and hold for 25 minutes.

[0031] The patent name is: a method for processing granular green tea, and the patent application number is: 201010039564.8 The processing method provided by the invention patent is a comparative example.

[0032] After brewing the granular green tea obtained in Examples 1 to 3 and Comparative Example respectively under the same environment with the same weight, the results in Table 1 are obtained after testing:

[0033] Table 1

[0034]

[0035] As can be seen from the above table, compared with the granular green tea obtained by using the processing method of the comparative patent, the granular green tea produced by the present invention has a round and tight shape, less broken foam, and better uniformity. And the brewed soup is green and clear, with pure aroma and...

Abstract

The invention discloses an easy-to-brew granulated green tea processing technology. The processing technology comprises the steps of fixation, rolling, rolling and cutting and drying; before fixation is conducted, needle-punched hole punching is conducted on picked tea leaves through a needle plate; after rolling and cutting are conducted, formed granulated green tea is subjected to expanding treatment and pressure-releasing freezing treatment; for expansion, the granulated green tea is put into an expanding machine, the control temperature ranges from 50 DEG C to 80 DEG C, the pressure ranges from 0.2 MPa to 0.4 MPa, and the retention time ranges from 5 min to 25 min; for pressure-releasing freezing, after expanding treatment is completed, a pressure releasing system is opened, the pressure is instantly released to 0.01 MPa to 0.08 MPa, when pressure releasing is conducted, the temperature is rapidly decreased to -10 DEG C to 4 DEG C, and the retention time ranges from 5 min to 25 min; in the drying process, the room temperature is kept, and air-drying is conducted on the granulated green tea. The granulated green tea obtained through the processing technology is high in leaching rate, low in slag quantity and high in tea quality.

Description

technical field [0001] The invention relates to the processing field of granular green tea, in particular to an easy-to-brew granular green tea processing technology. Background technique [0002] Granular green tea is a bulk green tea product that is directly processed by using medium and low-grade fresh leaf raw materials. The specification is 12-40 mesh granular green tea. As early as the 1980s, scientific research institutes carried out research on the development of granular green tea, and its processing technology and product quality have basically stabilized. Granular green tea has become an important product category in bulk green tea at that time. According to the basic processing technology of green tea, it is generally: fresh leaves are cleaned, kneaded, kneaded, cut, and dried, and then refined and arranged to obtain finished products. To process granule green tea, the fresh leaves of the raw materials used are generally the fresh leaves of tea trees in late spr...
