[0002] Black tea withering is one of the important steps in the production process of black tea. It refers to spreading evenly under certain temperature and humidity conditions, so that the activity of enzymes in fresh leaves can be moderately promoted, and the contained substances will undergo moderate physical and chemical changes, and some moisture will be emitted. The stems and leaves wilt, the color is dark green, and the grass gas is lost, which can improve the aroma and theaflavin content of the tea, but the wilting in the natural environment is not only difficult to meet the optimal requirements of temperature and humidity
For this reason, the existing hot air withering equipment is used for withering, but the time of natural withering or hot air withering is relatively long, which will affect the time of making the whole tea leaves.

The invention relates to composite withering equipment for tea leaf processing. The equipment comprises a rack, wherein a withering conveying belt and a heating withering box are arranged on the rack, a natural withering frame and a heating withering box are arranged on the heating withering box, at least two groups of tea leaf withering frames are arranged in the heating withering box, a turnover assembly is arranged at the bottom of the heating withering box, a hot air assembly is arranged below the tea leaf withering frames, and a movable conveying vehicle is arranged outside the heating conveying belt. According to the invention, during use, a placing and collecting tea leaf loading frame on which tea leaves are laid is conveyed to an external natural withering frame through a conveying vehicle to be subjected to sun withering and standing withering, a withering conveying belt is driven by a stepping motor to drive the natural withering frame to move into a heating withering box, hot air is conveyed through a hot air conveying assembly, the tea leaf withering frame is overturned through aturnover assembly, then the withering conveying belt is driven to convey the tea leaf withering frame to the output end, and finally the tea leaf withering frame is taken out from the output end of the withering conveying belt through the conveying vehicle, so that the purpose of automatic composite withering is achieved, and the withering time of the tea leaves is shortened.
Description
technical field [0001] The invention relates to the technical field of tea production, in particular to a compound wilting equipment for tea processing. Background technique [0002] Black tea withering is one of the important steps in the production process of black tea. It refers to spreading evenly under certain temperature and humidity conditions, so that the activity of enzymes in fresh leaves can be moderately promoted, and the contained substances will undergo moderate physical and chemical changes, and some moisture will be emitted. The stems and leaves wilt, the color is dark green, and the grass gas is lost, which can improve the aroma and theaflavin content of the tea, but the wilting in the natural environment is not only difficult to meet the optimal requirements for temperature and humidity. Existing withering is carried out by hot air wilting equipment for this reason, but no matter be the time of natural withering or hot air withering all longer, can influenc...
