Embodiment 1

[0022] A processing method of sweet potato vine tea, comprising the following steps:

[0023] (1) Collect fresh sweet potato vines (take the part of fresh sweet potato stems), wash them, dry them in the air for 3 hours, and cut them into sweet potato vines with a length of 1-1.5 cm;

[0024] (2) Use a 1000W microwave oven to microwave the sweet potato vines at 118°C for 45 seconds to obtain the green vines;

[0025] (3) Knead the vines: take the leaves to the upper edge of the flat kneading barrel as the standard, and press the leaves flat and slightly; empty kneading (even if the cover is slightly connected to the vines, without applying pressure) for 10 minutes, you have to knead the vines (the above empty kneading conventional meaning in this field);

[0026] (4) fire-drying the twisted rattan hair to a water content of 20% to 25%;

[0027] (5) After spreading for 28 minutes, bake on high heat until the water content is 5-6%.

Embodiment 2

[0029] A processing method of sweet potato vine tea, comprising the following steps:

[0030] (1) Collect fresh sweet potato vines (take the part of fresh sweet potato stems), wash them, dry them in the air for 2 hours, and cut them into sweet potato vines with a length of 1-1.5 cm;

[0031] (2) Use a 1000W microwave oven to microwave the sweet potato vines at 110°C for 30 seconds to obtain the green vines;

[0032] (3) Knead the vines: take the leaves to the upper edge of the flat kneading barrel as the standard, and press the leaves flat and slightly; knead them empty (even if the cover is slightly connected to the vines, without applying pressure) for 9 minutes, you have to knead the vines (the above empty kneading conventional meaning in this field);

[0033] (4) fire-drying the twisted rattan hair to a water content of 20% to 25%;

[0034] (5) After spreading for 20 minutes, bake on high heat until the water content is 5-6%.

Embodiment 3

[0036] A processing method of sweet potato vine tea, comprising the following steps:

[0037] (1) Collect fresh sweet potato vines (take the part of fresh sweet potato stems), wash them, dry them in the air for 4 hours, and cut them into sweet potato vines with a length of 1-1.5 cm;

[0038] (2) Use a 1000W microwave oven to microwave the sweet potato vines at 120°C for 50 seconds to obtain the green vines;

[0039] (3) Knead the vines: take the leaves to the upper edge of the flat kneading barrel as the standard, and the leaves should be flat and slightly pressed; kneading (even if the cover is slightly connected to the vines without applying pressure) for 11 minutes, the vines (the above-mentioned empty kneading conventional meaning in this field);

[0040] (4) fire-drying the twisted rattan hair to a water content of 20% to 25%;

[0041] (5) After spreading for 35 minutes, bake on high heat until the water content is 5-6%.

Abstract

The present invention relates to sweet potato vine tea and a processing method thereof. The processing method comprises the following steps: (1) fresh sweet potato vines are collected, the collected sweet potato vines are washed clean, the washed sweet potato vines are sun-dried, and the sun-dried sweet potato vines are cut to obtain sweet potato vine segments; (2) the sweet potato vine segments are subjected to a microwave enzyme deactivating at 110-120 DEG C for 30-55 s to obtain enzyme deactivated vines; (3) the enzyme deactivated vines are subjected to a slight kneading for 9-11 min to obtain kneaded vines; (4) the kneaded vines are subjected to a first fire drying until a water content is 20-25%; and (5) the dried kneaded vines are air-spread for 20-35 min and the air-spread vines are dried using sufficient fire until the water content is 5-6% to obtain the finished products. The finished products of tea soup contain active ingredients and the processing method removes plant gas, enables the tea to be mellow in taste, improves the taste of the tea soup and increases the aroma.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a sweet potato vine tea and a processing method thereof.
