Embodiment 1
[0070] A kind of black tea processing technology, it comprises the following steps:
[0071] (1) Tea screening
[0072] Select fresh tea leaves that are collected on the same day and have no mechanical damage, no insect eyes, and consistent tenderness, and select tea buds, tea leaves with one bud and one leaf, and tea leaves with one bud and two leaves to obtain the tea leaves to be processed;
[0073] (2) Frozen
[0074] After spreading out the tea leaves to be processed obtained in step (1), put them into a freezer with a model number of BD-380B and a power of 735W to freeze, and freeze them at a temperature of -18°C until the water inside the tea leaves to be processed is analyzed. And form ice crystals on the surface of the tea leaves, making the tea leaves hard and brittle to the extent that they can be crushed by hand, and frozen for 12 hours to obtain frozen tea leaves;
