The invention discloses a zinc-selenium tea processing technology. The zinc-selenium tea processing technology comprises tea leaf classification, tea leaf processing, tea leaf mixing, rolling, fixation, re-rolling and disentangling, fermentation, reshaping and discharge and specifically comprises the steps that step one, in the tea leaf classification, automatic tea-green separation is performed through a screen, tender leaves and old leaves which are classified are cleaned, and impurities are removed for standby application; step two, in the tea leaf processing, the tender leaves and the old leaves obtained in the step one are respectively processed for standby application; step three, in the tea leaf mixing, the tea leaves prepared in the step two are mixed according to the 1:10 weight ratio of old leaf residues to the tender leaves; step four, rolling is performed; step five, fixation is performed; step six, re-rolling and disentangling are performed; step seven, the fermentation is performed; step eight, the reshaping is performed; step nine, the discharge is performed. The tea leaves reshaped and processed undergo fixation in a fixation machine, and drying and sterilization are performed in the process of pushing the tea leaves out of the fixation machine. The zinc-selenium tea processing technology can well retain zinc-selenium elements, meanwhile the processing time is shortened, and the production efficiency is improved.
