Processing method for manufacturing tea by Dendrobium officinale dry leaves

Abstract

The invention discloses a processing method for manufacturing tea by Dendrobium officinale dry leaves. The method comprises the following steps of: (1) collecting Dendrobium officinale leaves; (2)drying until the dryness is 80 to 85%, and storing the Dendrobium officinale leaves at a ventilated dry place; (3) carrying out mist spray by using hot water of 85 DEG C until surfaces of the dry leaves are wet, and covering by cloth to facilitate withering of the leaves; (4) continuously turning over at the constant temperature of 90 DEG C; (5) carrying out fast packaging by using a fast packaging machine, placing the packages into a package kneading machine to be packaged and kneaded, then putting into a loosening machine to be deblocked for two times repeatedly, and placing into a clean edible plastic bag to be fermented for 6 hours; (6) carrying out granulation: extruding left and right, front and back firstly by 10 Ps pressure, deblocking, repeating for four times, then repeating for 6 times again by using 11 Ps pressure, finally repeating for 8 times by 12 Ps pressure, and finishing granulating after particles take up not less than 95%; and (7) raising the temperature to 120 DEG C while drying at the temperature of 80 DEG C until the water content is 5 to 6%, carrying out packaging continuously for 5 minutes, and storing, then obtaining the Dendrobium officinale tea. The processing method for manufacturing the tea by the Dendrobium officinale dry leaves disclosed by the invention makes full use of precious resources, increases additional values of Dendrobium officinale and has a large-scale and mass production. Furthermore, the tea is brewed conveniently.

Description

technical field [0001] The invention relates to a processing method, in particular to a processing method for making tea from dried dendrobium officinale leaves. Background technique [0002] Dendrobium officinale is a widely used and extremely rare and precious Chinese medicinal material. It is listed as the top grade in "Shen Nong's Materia Medica", and it is also listed as one of the nine immortal grasses in the Taoist medical classic "Tao Cang" more than a thousand years ago ( Dendrobium candidum, Tianshan snow lotus, Sanliang ginseng, 120-year-old Polygonum multiflorum, Poria cocos, Cistanche, Shenshan Ganoderma lucidum, sea pearl, Cordyceps sinensis), known as life-saving celestial grass by the people. [0003] Modern pharmacological studies have shown that the main component of Dendrobium officinale is polysaccharide (20-40% in fresh leaves), which is also rich in various amino acids and trace elements, etc. Liver improves eyesight, improves human immune function, pr...

Problems solved by technology

[0004] At present, Dendrobium officinale is mostly cultivated artificially, and the harvesting period is relatively long (November to March of the following year), while the traditional production method is to pick and make on the spot, and the amount of fresh strips harvested each time depends on the needs of customers. It is generally scattered, and the traditional tea-making process is accustomed to using stems of Dendrobium candidum, so the existing leaves of Dendrobium candidum are basically wasted
