Preparation method of granular black tea

The invention provides a making method of granular black tea, and relates to the field of black tea making, the making method of the granular black tea comprises material selection, withering, rolling, fermentation, granule shaping, drying and sieving, when tea leaves are subjected to granule shaping, the pressure of pressing each time is gradually increased, pressing is carried out for multiple times, and the tea leaves are subjected to drying and sieving; according to the method, the moisture regaining humidity is gradually reduced after multiple times of pressing, so that precursor substances of aroma in the black tea can be properly converted, the condition of excessive oxidation is not easy to occur, more aroma components are formed, the moisture regaining time is shortened, and the taste of the black tea is improved. The tea leaves are in a round and tight particle state during continuous pressurization, and as the tea leaves are tightly wrapped, the smell of the tea leaves is slowly released in the sto
