The invention is applicable to the field of tea
processing, and provides a preparation method of single-
plant tabletted dark tea, which comprises the following steps: spreading fresh leaves at 25-28 DEG C and
humidity of 70% for 4-6 hours; performing fixation for 2-3 minutes at 240-260 DEG C by adopting a roller fixation
machine; applying pressure of 0.5-0.8 MPa, and rolling for 20 minutes;
carding with the vibration frequency of 40Hz; performing
pile fermentation for 7-10 days at the temperature of 35-38 DEG C and the
humidity of 85%; pressing at 10-15kN to form a strip-shaped
sheet structure; performing primary
drying at 60 DEG C, secondary
drying at 45 DEG C, sufficient
drying at 30 DEG C and gradient drying, wherein the total time is 6-8 hours; finally, under the conditions that the temperature is 25-28 DEG C and the
humidity is 75%-80%, naturally floating or inoculating eurotium cristatum, and culturing for 5-7 days, so as to obtain a finished product. According to the invention, by selecting raw materials and innovating the process, the single-
plant tabletted dark
green tea which is regular in shape, convenient to take and use, controllable in floating, excellent in quality and capable of meeting the standard is obtained, and the practicability and market competitiveness of the product are remarkably improved.
