Abstract

The invention discloses a technology for processing platycodon grandiflorus leaf tea and belongs to the technical field of tea processing. The technology comprises the following steps: picking fresh leaves of platycodon grandiflorus, cleaning the platycodon grandiflorus leaves to remove impurities with clean water, spreading the cleaned platycodon grandiflorus leaves, fixing the spread leaves, putting primary fixed leaves into a rolling machine, performing primary rolling under normal temperature and pressure-free conditions, and performing primary rolling for 22-28 minutes so as to obtain primary rolled leaves; spraying white spirit into the primary rolled leaves, putting the primary rolled leaves into the rolling machine, performing secondary rolling at a temperature of 40-50 DEG C, performing secondary rolling for 20-30 minutes, slightly pressing for 14-18 minutes, heavily pressing for 12-18 minutes, fixing the secondary rolled leaves again, adding the secondary fixed leaves into the rolling machine, controlling the temperature of the rolling machine to 30-40 DEG C, rolling for the fourth time for 20-30 minutes, slightly pressing for 10-20 minutes, loosening for 5-10 minutes, and feeding the third rolled leaves into a drying machine to be dried, namely obtaining the product. The platycodon grandiflorus leaf tea processed by the technology disclosed by the invention is greenin color, green and transparent in soup and heavy and mellow in taste.

Description
