The present invention relates to a black tea processing method, and in particular to a congou black tea processing technology. The processing technology comprises the following steps: step 1, lifting a twisting mechanism, and putting black tea into a bucket body; step 2, putting down the twisting mechanism, and starting a No.2 power member of a rotary table to enable the rotary table to rotate to start kneading and twisting the black tea; step 3, filling a twisting barrel with water through a water inlet pipe; step 4, starting a power member connected to a stirring impeller, so as to enable the stirring impeller to stir the water in the twisting barrel; step 5, stopping the power member, pumping the water out of the twisting barrel, and allowing the rotary table to continue kneading and twisting the black tea; and step 6, stopping the No.2 power member, and taking out the black tea. In order to solve the problem in the prior art that a constant twisting strength leads to a poor twisting effect, the invention aims to provide the black tea processing technology with a varied twisting strength in twisting processes.
