Method for sterilizing green tea leaves

Abstract

The invention discloses a method for sterilizing green tea leaves and relates to the technical field of tea leaf processing. The method includes: S1, subjecting manually collected tea leaves to preliminary drying through a roller dryer; S2, subjecting the tea leaves after being dried in the S1 to preliminary screening for impurity removal through a vibration sifter to remove impurities and dust inthe tea leaves; S3, using ultraviolet of 250-260nm in wavelength to perform preliminary sterilization on the tea leaves after impurity removal in the S2 for 5-10min; S4, performing secondary impurityremoval on the tea leaves after preliminary sterilization in the S3 through a material cyclone separator. Quick sterilization is performed within a short time, and sterilization is uniform and thorough; the tea leaves are less prone to coking during sterilization, so that active ingredients can be reserved; the tea leaves are sterilized for several times, so that sterilization quality is improvedto great extent, and fragrance quality of the tea leaves is improved greatly; the impurities in the tea leaves are well filtered, and the tea leaves are hermetically packaged, so that tea leaf processing quality is improved greatly.
