Processing technology of oolong tea

Abstract

The invention provides a processing technology of oolong tea, and relates to the field of processing of tea leaves. The processing technology comprises the following steps of selecting fresh leaves from tea trees, and performing spreading for air-drying on the fresh leaves; selecting fresh semen cassiae leafbuds, and ginkgo leafbuds, and adding withered tea leaves to a machine for rocking of greenleaves for making of green leaves; mixing the tea leaves with the semen cassiae leafbuds and ginkgo leafbuds to obtain a mixture, spreading the mixture for heat dissipation, putting the mixture afterheat dissipation in a rolling bucket, and performing rolling; controlling the room temperature during fermentation to be 22-24 DEG C, controlling the fermentation temperature of the tea leaves to be28 DEG C, controlling the humidity to be 90%, and controlling the fermentation time to be 4-5h; performing refrigeration drying treatment on the treated tea leaves; performing steam fixation treatment; and sending the treated tea leaves in a microwave fixation machine and performing fixation once again. According to the processing technology disclosed by the invention, running off of nutrients isavoided, low-pressure steam fixation is adopted, the tea leaves can absorb heat under the low-pressure steam environment, the condition that the leaves are maintained complete is facilitated, and fixation is performed for the second time after steam fixation to remove remaining moisture in the tea leaves. The semen cassiae leafbuds and the ginkgo leafbuds are added, so that the tea leaves are richer in mouth feel.

Problems solved by technology

The greening of tea includes roller fixing and microwave fixing. The aroma of tea leaves obtained by roller fixing is pleasant, but it often appears that the fixing is not transparent and uneven; microwave fixing can heat the inner and outer surfaces of the tea at the same time, and the fixing is thorough and even. But the aroma of the tea obtained is not enough
