Energy-saving dustproof broken black tea production line

Abstract

The invention relates to an energy-saving dustproof broken black tea production line. The energy-saving dustproof 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, the screening efficiency of the stalk-sorting machine is better, and more thorough, and dust pollution can be avoided; rotating rollers and feed rotating rollers are arranged in a box body of the drying machine, a material bearing plate located at a discharge notch turns over, 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 therefore, not only is the drying efficiency more uniform, but also the continuous drying form can enable the drying efficiency to be effectively improved. In addition, an air suction passage formed on the top surface of the box body is connected with an air inlet of a hot air furnace, so that the quantity of heat of gas exhausted from the drying machine can be effectively recovered, and fuel is saved.

Description

technical field [0001] The invention belongs to the technical field of red crushed tea production equipment, and in particular relates to an energy-saving and dust-proof red crushed tea production line. Background technique [0002] Broken red tea is a bulk product in the international tea market, currently accounts for about 80% of the world's total tea export volume, and has a production history of more than 100 years, while it has been developed in my country for nearly 30 years. [0003] In the production process of crushed red tea, it is first necessary to chop the cooled and withered tea leaves for the first time, and then remove the tea stems contained therein. Although the existing hammer cutting machine can meet the requirements of use to a certain extent, it still has the disadvantages of uneven particle size and troublesome cleaning and maintenance. In the prior art, large-scale enterprises generally use electrostatic stem sorting machines to remove tea stems fro...

AI Technical Summary

Problems solved by technology

Although the existing hammer cutting machine can meet the requirements of use to a certain extent, it still has the disadvantages of uneven particle size and troublesome cleaning and maintenance.

In the prior art, large enterprises generally use electrostatic stem sorting machines to remove tea stems from broken tea, but electrostatic stem sorting machines have the problems of large investment and high cost

For small enterprises, ordinary sieves are generally used for screening, which has the problems of low work efficiency and unclean removal of tea stems.

In addition, in the existing equipment, when the tea leaves are hammered and cut, the tea leaves are generally placed in containers and then manually transferred to the stem picking equipment, which not only takes time and effort, but also reduces production efficiency; the existing black tea drying equipment Although it can meet the requirements of use to a certain extent, because the red broken tea is placed statically inside the drying equipment, there are problems of low drying efficiency and uneven drying degree.
