Embodiment 1

[0023] Embodiment one: the processing method of instant green tea powder, comprises the following steps:

[0024] (1) Material preparation: pick fresh tea leaves, and remove yellow leaves and impurities mixed in when picking;

[0025] (2) Integration of greening and crushing: place the fresh tea leaves to be processed in the vacuum chamber, and slowly introduce inert gas, firstly vacuumize the vacuum chamber, and then pump up the vacuum chamber to a certain degree of vacuum , the tea leaves in the vacuum chamber are heated and fixed, the absolute vacuum degree is 22kPa, and the time for curing is 2min; then the crushing link is carried out in the vacuum chamber, and the normal pressure in the vacuum chamber is restored within 2s, and the temperature is lowered at the same time. -20°C, at this time, the tea leaves hit the bulge at the bottom of the vacuum chamber; after waiting for 15 seconds, slowly evacuate the vacuum chamber to a certain degree of vacuum, and at the same tim...

Embodiment 2

[0031] Embodiment two: the processing method of instant green tea powder, comprises the following steps:

[0032] (1) Material preparation: pick fresh tea leaves, and remove yellow leaves and impurities mixed in when picking;

[0033] (2) Integration of greening and crushing: place the fresh tea leaves to be processed in the vacuum chamber, and slowly introduce inert gas, firstly vacuumize the vacuum chamber, and then pump up the vacuum chamber to a certain degree of vacuum , the tea leaves in the vacuum chamber are heated and fixed, the absolute vacuum degree is 24kPa, and the time for curing is 3min; then the crushing link is carried out in the vacuum chamber, and the normal pressure in the vacuum chamber is restored within 2s, and the temperature is lowered at the same time. -28°C, at this time, the tea leaves hit the protrusion at the bottom of the vacuum chamber; after waiting for 15s, slowly vacuum the vacuum chamber to a certain degree of vacuum, and at the same time ra...

Embodiment 3

[0039] Embodiment three: the processing method of instant green tea powder, comprises the following steps:

[0040] (1) Material preparation: pick fresh tea leaves, and remove yellow leaves and impurities mixed in when picking;

[0041] (2) Integration of greening and crushing: place the fresh tea leaves to be processed in the vacuum chamber, and slowly introduce inert gas, firstly vacuumize the vacuum chamber, and then pump up the vacuum chamber to a certain degree of vacuum , the tea leaves in the vacuum chamber are heated and fixed, the absolute vacuum degree is 28kPa, and the killing time is 4min; then the crushing link is carried out in the vacuum chamber, and the normal pressure in the vacuum chamber is restored within 2s, and the temperature is lowered at the same time. -35°C, at this time, the tea leaves hit the protrusion at the bottom of the vacuum chamber; after waiting for 15 seconds, slowly vacuum the vacuum chamber to a certain degree of vacuum, and at the same t...

Abstract

The invention relates to the field of agriculture product processing and specifically relates to a processing method for instant green tea powder. The method comprises the following steps: (1) preparing materials; (2) integrally killing out and crushing; (3) extracting a nutrient solution; (4) filtering; (5) concentrating; (6) forming; and (7) drying. The processing method provided by the invention has a good crushing effect and has the effect of keeping the original tea taste.

Description

technical field [0001] The invention relates to the field of agricultural product processing, in particular to a processing method of instant green tea powder. Background technique [0002] Tea is divided into three categories: non-fermented tea, semi-fermented tea and fermented tea. Green tea belongs to non-fermented tea and is the main traditional beverage in China. Green tea contains natural nutrients such as tea polyphenols, chlorophyll, catechins, caffeine and vitamins, which have special effects on anti-aging, anti-cancer, sterilization and anti-inflammatory. Because green tea contains more tea polyphenols and caffeine substances with a bitter taste, the taste is not good, and the aroma is poor. In industrial production, we have been exploring the process of preparing green tea with strong aroma, good taste and high quality. [0003] In recent years, there have been more and more researches and reports on green tea, and the research on instant green tea powder has als...
