Embodiment 1

[0034] A kind of preparation method of dendrobium candidum leaf tea, it comprises the following steps:

[0035] Step 1, raw material preparation: picking fresh tender leaves of Dendrobium candidum as raw material;

[0036] Step 2, raw material testing: the fresh Dendrobium officinale leaves picked in step 1 are tested for heavy metals and pesticide residues to ensure that the heavy metals and pesticide residues meet the standards;

[0037] Step 3, withering process: the fresh Dendrobium candidum leaves lose 50% of water by sun exposure;

[0038] Step 4, kneading process: Put the leaves of Dendrobium candidum through the withering process into a rolling machine and knead for 60 minutes. When the leaves of Dendrobium candidum are tightly rolled into strips without loose folding, when the leaves of Dendrobium candidum that have been kneaded by hand have leaf juice overflowing Kneading can be ended; among them, the pressurization principle of the whole kneading process is the pri...

Embodiment 2

[0043] A kind of preparation method of dendrobium candidum leaf tea, it comprises the following steps:

[0044] Step 1, raw material preparation: picking fresh tender leaves of Dendrobium candidum as raw material;

[0045] Step 2, raw material testing: the fresh Dendrobium officinale leaves picked in step 1 are tested for heavy metals and pesticide residues to ensure that the heavy metals and pesticide residues meet the standards;

[0046] Step 3, withering process: adopting the method of air blowing to make fresh Dendrobium officinale leaves lose 45% of water;

[0047] Step 4, kneading process: Put the leaves of Dendrobium candidum through the withering process into a kneading machine and knead for 50 minutes.

Abstract

The invention relates to the technical field of dendrobium officinale leaf tea, in particular to a preparation method of dendrobium officinale leaf tea. The preparation method of the dendrobium officinale leaf tea comprises steps as follows: S1, preparation of raw materials; S2, detection of the raw materials; S3, a withering process; S4, a rolling process; S5, a deblocking process; S6, a piling process; S7 a drying process. According to the preparation method of the dendrobium officinale leaf tea, the prepared dendrobium officinale leaf tea cannot have acerbic taste in combination with the deblocking process and the piling process, and the fragrance and taste of the dendrobium officinale leaf tea can be improved. Besides, in the drying process, the dendrobium officinale leaf tea is firstly dried at the high temperature and then dried at the low temperature, so that honey fragrance of dendrobium officinale leaves can be conveniently separated out, and the dendrobium officinale leaf tea tastes mellower and stronger.
