Problems solved by technology

However, due to the high polysaccharide and amino acid content of Dendrobium officinale itself, a large amount of organic acids will be produced during the fermentation process, of which the highest content is acidic glutamic acid. Due to the large amount of glutamic acid produced during the fermentation process, the iron skin Dendrobium leaf tea has problems such as sour taste and weak tea fragrance

Embodiment 1

[0015] 1) Sorting The fresh leaves of Dendrobium officinale are screened, and the complete and dark green fresh leaves are picked out and evenly spread on the overhead clean mesh bamboo mat for 3 days. When the water content of the fresh leaves reaches 65%, it is transferred to the next process ;

[0016] (2) Withering Spread the leaves of Dendrobium candidum evenly on the withering tank according to the thickness of 18cm, wither until the tea leaves shrink and become soft, the leaves feel soft when pinched by hand, there is no friction sound, the leaves form a ball when held tightly, and the leaves loosen slowly when you let go. The leaf color turns dark green, the surface luster disappears, the grassy smell of fresh leaves fades, and the unique fragrance of withered leaves appears;

[0017] (3) Greening is done with a drum continuous greening machine. The temperature of greening is 120°C and the time is 35s. The water content of the leaves after greening is controlled at 58%...

Embodiment 2

[0023] 1) Sorting The fresh leaves of Dendrobium officinale are screened, and the complete and dark green fresh leaves are picked out and evenly spread on the clean mesh bamboo silk mat for 4 days. When the water content of the fresh leaves reaches 70%, it is transferred to the next process ;

[0024] (2) Withering Spread the leaves of Dendrobium officinale evenly on the withering trough with a thickness of 19cm, and wither until the tea leaves shrink and become soft, the leaves feel soft when pinched by hands, there is no friction sound, the leaves form into agglomerates when held tightly, and the leaves loosen slowly when you let go. The leaf color turns dark green, the surface luster disappears, the grassy smell of fresh leaves fades, and the unique fragrance of withered leaves appears;

[0025] (3) Greening is done with a drum continuous greening machine, the temperature of greening is 130°C, and the time is 60s. After the greening, the water content of the leaves is contr...

Embodiment 3

[0031] 1) Sorting Screen the fresh leaves of Dendrobium candidum, pick out the complete, dark green fresh leaves and spread them evenly on the clean mesh bamboo silk mat for 5 days, and transfer to the next process when the water content of the fresh leaves reaches 75% ;

[0032] (2) Withering Spread the leaves of Dendrobium candidum evenly on the withering tank according to the thickness of 20cm, wither until the tea leaves shrink and become soft, the leaves feel soft when pinched by hands, there is no friction sound, the leaves form into agglomerates when held tightly, and the leaves loosen slowly when you let go. The leaf color turns dark green, the surface luster disappears, the grassy smell of fresh leaves fades, and the unique fragrance of withered leaves appears;

[0033] (3) Greening is done with a drum continuous greening machine. The temperature of greening is 140°C and the time is 90s. After the greening, the water content of the leaves should be controlled at 60%. ...

Abstract

The invention relates to the technical field of dendrobium officinale processing and in particular relates to a processing method of dendrobium officinale leaf tea. The processing method comprises the following steps: sorting, withering, shaking, rolling, fermenting, deacidifying and plasticity-drying. According to the technical scheme, as the step of deacidifying is added after the fermenting, organic acid contained by part of dendrobium officinale leaves can be neutralized, organic acid generated in the fermenting process can be also neutralized, then the pH of tea soup of dendrobium officinale leaf tea reaches about 5 and is 1.5 higher than the pH of the tea soup of the dendrobium officinale leaf tea produced by adopting a conventional method, and therefore, the produced dendrobium officinale leaf tea achieves the best drinking effect, and the produced dendrobium officinale leaf tea does not have the acor feeling and achieves the effect of pure tea soup flavor. Meanwhile, the dendrobium officinale leaf tea has the effects of nourishing yin, boosting essence, beautifying, expelling toxin, nourishing stomach, lubricating intestines, improving eyesight and brightening eye, and has the good improvement effect on immunity enhancing, insomnia, cardiovascular and cerebrovascular diseases, and diabetes.
