Abstract
PURPOSE: To obtain a high-quality green tea having no steaming unevenness from a leaf part to a vegetative part, by steaming leaves of green tea with the vegetative part still attached by pressurized steam with a specific pressure, releasing them to atmospheric pressure so that they are swelled.
CONSTITUTION: Fresh leaves of greeen tea fed from the airtight feeder 1 having the rotary valve 2 to the approximately airtight steaming chamber 18 are steamed by pressurized steam having a fixed vapor pressure selected from gauge pressure of 0.2W4.0kg/cm2, fed from the steam pipe 52, while being sent by the net conveyor 25. By this steaming, oxidase is deactivated, the immbolization of chlorophyll and the softening treatment of the leaf part and the vegetative part are carried out uniformly while the vaporization of fragrant components is being suppressed. The steamed leaves are released from the airtight discharging device 8 to atmospheric pressure or a vacuum chamber ≤ atmospheric pressure, and the vegetative part and the leaves are swelled and cooled.
