1. microwave dries the two blue or green and pair granulated green tea processing methods that pots song milli machine shaping is combined, and it is characterized in that comprising following processing step:

  • 1) fresh leaf spreads;

    select the And Development of Tea Shoot that tea picking machine is plucked, and controls fragment leaf and monolithic leaf proportion more than 20%, and get tea fresh leaves and be placed on greenness preservation machine and spread, leaf-spreading thickness 5-10cm, spreads time 4-8h, makes to spread leaf moisture content and is down to 70-75%;

    2) complete;

    spread leaf and adopt roller fixation machine to complete, control completes, and temperature is 180-220 DEG C, fixation time is 60-75s;

    3) spreading for cooling;

    carry out spreading for cooling immediately after completing, get damp again 10-20min naturally;

    4) knead;

    adopt kneading machine to knead after water-removing leaves spreading for cooling, the time of kneading is 15-20min, and pressuring method is " light-heavy-light ";

    5) dry two blue or green;

    knead transport tape that leaf is placed on microwave machine carries out dewater, color retention, controlling microwave machine power is 10-15KW, and the transport tape speed of microwave machine is 200-250r/min, and microwave machine process to moisture content is 30-40%;

    6) shaping;

    two leafiness are placed in two pots bent milli machine and carry out shaping process, control to throw amount 10-15 kilogram/pot, leaf, the temperature and time that wherein leading portion is used is respectively 130-160 DEG C and 30-45min, and back segment temperature and time used is respectively 110-140 DEG C and 25-40min;

    7) spreading for cooling;

    timely spreading for cooling moisture regain after shaping, get damp again 30-40min naturally;

    8) dry;

    shaping leaf utilizes tea drier to carry out drying, and hot blast temperature is 80-100 DEG C, and drying time is 20-30min;

    9) Titian;

    adopt perfuming machine for tea Titian after dry, Titian temperature is 90-110 DEG C, and the Titian time is 10-15min.
