Continuous production line for preparing export tea by using exogenous enzymes

Abstract

The invention discloses a continuous production line for preparing export tea by using exogenous enzymes. The production line comprises: a withering machine, a rolling unit and a first pile fermentation chamber which are sequentially connected together through a conveying device, and a movable spreading platform and a saccharifying machine which are arranged in the first pile fermentation chamber.The production line also comprises a moisture regaining and softening unit, discharge ports of the moisture regaining and softening unit and the saccharifying machine are connected to a mixing machine through a conveying device, and a second pile fermentation chamber, a shaking screen machine, a drying machine, a third pile fermentation chamber, a shaping machine, a fragrance improving and sterilizing machine, a polishing unit, a shaking screen grading machine and a uniform piling machine are sequentially connected behind the mixing machine through a conveying device. The production line is high in automation degree, parameters such as temperature and humidity required by tea processing can be conveniently controlled, and meanwhile, the cleanliness is high. The export tea prepared by theproduction line is eyebrow-shaped in appearance, dark brown and oily in color and luster, yellow red and bright in soup color after being brewed, similar to yellow wine color, yellowish brown and light red in leaf base, thick and sweet in taste, strong and mellow in tea aroma and prominent in sweet aroma.
