Embodiment 1

[0023] A processing method of dendrobium scented tea, comprising the following steps:

[0024] (1) gather the dendrobium flower;

[0025] (2) Withering the Dendrobium flowers at 28-32° C. for 12 hours until the water content is 60-62%, to obtain withered flowers;

[0026] (3) Knead the withered flowers: take the flowers to the upper edge of the flat kneading barrel as the standard, and the flowers should be flat and slightly pressed; empty kneading (even if the kneading cover is slightly attached to the withered flowers, without applying pressure) for 6 minutes, you can knead the flowers (above Empty is the conventional meaning in this field);

[0027] (4) ferment the kneading flowers for 3.5 hours, the fermentation temperature is 26-28° C., and the relative humidity is above 90%, to obtain fermented flowers;

[0028] (5) Microwave-dry the fermented flower with a 1000W microwave oven at 100°C until the water content is 30-35%, to obtain the first-baked flower;

Abstract

The invention relates to a dendrobium flower tea and a processing method thereof. The processing method includes the steps: (1) collecting fresh dendrobium flowers; (2) withering the fresh dendrobium flowers for 10-14 hours until the water content of the fresh dendrobium flowers reaches 58-62% to obtain withered flowers; (3) lightly rolling the withered flowers for 5-7 minutes to obtain rolled flowers; (4) fermenting the rolled flowers for 3-4 hours to obtain fermented flowers; (5) drying the fermented flowers by microwave until the water content of the fermented flowers reaches 30-35% to obtain primary dried flowers; (6) hermetically stacking the primary dried flowers for 3-4 hours with heat and then drying the primary dried flowers by complete fire until the water content reaches 5-6% to obtain the dendrobium flower tea. According to the processing method, cells can be properly damaged in a lightly rolling manner, the content of water extract is increased, appearance integrity of the dendrobium flower tea cannot be damaged, effective substances in dendrobium flowers are converted by thermo-chemical functions when the dendrobium flowers are hermetically stacked after dried to reach proper water content by the microwave, the water extract is increased, and fragrance is lasting.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a dendrobium scented tea and a processing method thereof. Background technique [0002] Dendrobium is contained in "Shen Nong's Materia Medica", and is listed as top grade. It is a perennial herb. Dendrobium grows in tropical and subtropical virgin forests and similar warm and humid environments. It is mostly epiphytic on large tree trunks or rocks. It has good curative effects on tumors, improving human immunity, treating gastrointestinal diseases, anti-aging, anti-oxidation, anti-platelet aggregation, lowering blood sugar and treating cataracts. Dendrobium is the flower of Dendrobium. In addition to its ornamental value, its main component is volatile oil, which has the effects of clearing heat and promoting body fluid, nourishing yin and relieving depression, and lowering blood pressure. It is a good product for health preservation in summer. [0003] Existing processing of dend...
