Embodiment 1
[0043] 1) Raw materials: select 10kg of fresh tea leaves grown in the year;
[0044] 2) Withering: adopt natural withering, the thickness of the fresh tea leaves is 4cm, the withering temperature is 25°C, the time is 9 hours, and lightly loosen once during the withering period;
[0045] 3) Kneading: Use the 6CR-55 kneading machine to sequentially knead, lightly knead, heavy knead, and empty knead, and knead for 5 minutes at each stage;
[0046] 4) Primary crushing: Preliminary crushing of the kneading leaves with a rotor kneading and cutting machine, and passing through an 8-mesh sieve.
[0047] 5) Fermentation: Put the first crushed leaves in the fermentation room, break up the tea leaves and lay them flat, the thickness is controlled at 6cm, the indoor temperature is 28°C, the relative humidity is above 90%, and the fermentation time is 30min. The fermented leaves are red in color and have a strong floral and fruity aroma. The fermentation time can be extended appropriatel...
Embodiment 2
[0054] 1) Raw materials: select 10kg of fresh summer tea leaves grown in the year;
[0055]2) Withering: adopt natural withering, the thickness of the fresh tea leaves is 4cm, the withering temperature is 30°C, the time is 16 hours, and lightly loosen twice during the withering period;
[0056] 3) Kneading: Use the 6CR-55 kneading machine to knead for 5 minutes, lightly knead for 5 minutes, heavy knead for 10 minutes, and empty for 5 minutes. After the re-kneading stage was extended to 10 minutes, the color quality of tea powder products was higher.
[0057] 4) Primary crushing: the kneading leaves are preliminarily crushed to below 8 mesh with a rotor kneading and cutting machine, and passed through an 8 mesh sieve. The rotor kneading and cutting machine can crush the kneading leaves by connecting two in series.
[0058] 5) Fermentation: Put the first crushed leaves in the fermentation room, break up the tea leaves and lay them flat, the thickness is controlled at 6cm, the ...
Embodiment 3
[0065] 1) Raw materials: select 10kg of fresh summer tea leaves grown in the year;
[0066] 2) Withering: adopt natural withering, the thickness of the fresh tea leaves is 3cm, the withering temperature is 20°C, the time is 16 hours, and lightly loosen twice during the withering period;
[0067] 3) Kneading: Use the 6CR-55 kneading machine to knead for 5 minutes, lightly knead for 5 minutes, heavy knead for 10 minutes, and empty for 5 minutes.
[0068] 4) Primary crushing: the kneading leaves are preliminarily crushed to below 8 mesh with a rotor kneading and cutting machine, and passed through an 8 mesh sieve. The rotor kneading and cutting machine can crush the kneading leaves by connecting two in series.
[0069] 5) Fermentation: Put the first crushed leaves in the fermentation room, break up the tea leaves and lay them flat, the thickness is controlled at 6cm, the indoor temperature is 26°C, the relative humidity is above 90%, and the fermentation time is 60min. The ferm...
