Tea withering tank

Abstract

The invention discloses a tea withering tank which belongs to the field of tea processing equipment. A hot air generating mechanism is located between two support frames, and comprises a heating box;a fan is arranged at a bottom inside the heating box; a transverse clapboard is fixedly connected to the interior of the heating box; a plurality of through holes are formed in the clapboard; electricheating wires are arranged in all the through holes; two slide rails are, respectively, fixedly connected to rightly opposite inner walls of the heating box in a transverse manner; a time relay is inelectric connection with a double-shaft motor; roller wheels are fixedly connected to end parts of both output shafts of the double-shaft motor; the roller wheels are respectively located in the twoslide rails, and are in sliding contact with the slide rails; rotating rods are connected to output shafts of the double-shaft motor; one ends of the rotating rods, which are far away from the outputshafts, stretch out of the heating box from an opening of the heating box; a tea leaf containing basket is located above the heating box; an outer bottom of the tea leaf containing basket is connectedwith top ends of the two support frames; and the bottom of the tea leaf containing basket is made of a flexible ventilative material. The tea withering tank solves the problem of uneven tea leaf withering effect.

Description

technical field [0001] The invention relates to the field of tea processing equipment, in particular to a tea withering tank. Background technique [0002] Black tea is a fully fermented tea, which is made from suitable new tea tree leaves as raw materials and refined through a series of processes such as withering, rolling, fermenting, and drying. [0003] And withering is an important step in making black tea. Withering is to spread the tea leaves evenly under certain temperature and humidity conditions, moderately promote the activity of fresh leaf enzymes, and cause moderate physical and chemical changes in the substances contained in the tea leaves, and at the same time emit Part of the water will make the stems and leaves wilt, the color is dark green, and the grass gas will be lost. The current withering process generally uses a withering tank to wither tea leaves, but the existing withering tank is composed of four parts: a hot gas generator, a blower, a withering t...
