The invention relates to a broken
black tea production line. The broken
black tea production line comprises a primary hammering and
cutting machine, a stalk-sorting
machine, a stirrer, a secondary hammering and
cutting machine, a pelletizer, a round sifter, a fermenting tank and a
drying machine which are sequentially arranged, wherein a material collecting bin is arranged between the primary hammering and
cutting machine and the stalk-sorting machine, so that automatic
material transfer between the primary hammering and cutting machine and the stalk-sorting machine can be realized, and the screening efficiency of the stalk-sorting machine is better, and more thorough; rotating rollers and feed rotating rollers are arranged in a box body of the
drying machine, multilayer horizontal material conveyer segments are formed by a material conveyer belt arranged on the rotating rollers and the feeding rotating rollers in a sleeving manner, and a
discharge notch is formed in a support track; in the movement process of the material conveyer belt, a material bearing plate at the
discharge notch turns over under the action of gravity, and materials on the material bearing plate automatically fall into a horizontal material conveyer segment on a lower layer, so that automatic
material transfer between every two
layers of horizontal material conveyer segments is realized, and the materials are continuously dried along with the movement of the material conveyer belt; and therefore, not only is the
drying efficiency more uniform, but also the continuous drying form can enable the drying efficiency to be effectively improved.
