The invention relates to a white tea warm-withering method, which is characterized in that the production process has the following steps: 1, fresh tea sieving, namely, fresh white tea is filled into sieves; 2, delivery of fresh tea to the withering
greenhouse and hierarchical display, namely, the sieves loaded with fresh white teat are placed on iron shelves in the withering
greenhouse, layer by layer; 3, closing the
greenhouse door; 4, startup of a temperature controller, namely, the temperature controller on a temperature-controlled door is turned on; 5, startup of a
humidity controller, namely, the
humidity controller on the temperature-controlled door is turned on; 6, startup of a hot air circulation
machine; 7, startup of a ventilator; 8, starting of fresh tea withering, wherein, the temperature is 30-35 DEG C, the
relative humidity is 60% -70%, and the withering time is 18 hours; 9, hot air circulation, namely, the hot air circulation
machine ensures
equivalent temperature of the upper and lower
layers in the withering greenhouse, and automatically exhausts above temperature and
humidity, or automatically turns off under temperature and humidity; and 10, temperature-
time control, namely, the temperature at the earlier 3 hours is controlled at 30 DEG C, the temperature at the middle 12 hours is controlled at 32 DEG C, while the temperature at the later 3 hours is controlled at 35 DEG C. The invention adopts the mechanical heating-withering technology and can artificially control the white tea withering temperature and humidity so as to ensure the quality of the white tea, improve the productivity and achieve greater promotion and application values.
