[0022] A method for producing tea stem black tea by instant ejection steam explosion method includes the following steps:
[0023] (1) Tea stalk pretreatment: Select the Xinyang group species for tea, pick fresh tea stalks, the length of the tea stalks is 2-8cm, and wither naturally, spread the stalk thickness 2cm-5cm, wither to 50% water content, then spray 1% steam explosion protection agent, the tea stems are steam explosion treated by the instant ejection blasting method to obtain the tea stem explosions, which are reserved. The steam explosion treatment is: using the QBS-80B steam explosion process test bench, steam pressure Maintain for 60s under the condition of 1.5Mpa, and then eject steam to explode instantly and cool to normal temperature;
[0024] (2) Tea pretreatment: Choose the Xinyang group species for tea, pick the fresh leaves of one bud and two leaves, one bud and one leaf or single bud in spring, and carry out natural withering. The thickness of ...
