Convenient-to-maintain energy-saving broken black tea production line

Abstract

The invention discloses a convenient-to-maintain energy-saving broken black tea production line. The conveniently-maintained energy-saving broken black tea production line comprises a primary hammer cutting machine, a stem picking machine, a stirring machine, a secondary hammer cutting machine, a granulating machine, a circular sieve machine, a fermenting tank and a drying machine which are sequentially arranged, wherein a material collecting bin is arranged between the primary hammer cutting machine and the stem picking machine. One end of an upper casing of the primary hammer cutting machine is hinged to a lower casing, and a quick dismounting and quick mounting mechanism is arranged between the upper casing and the lower casing, so that during cleaning and maintenance, the upper casing can be opened for cleaning and maintaining a material hammer cutting cavity, and maintenance is convenient; automatic transfer of a material between the primary hammer cutting machine and the stem picking machine can be achieved, and the stem picking machine has higher sieving efficiency and more thorough sieving effect; through arrangement of rollers and feed rollers in the box body of the drying machine, the material moves along with a material conveying belt and is continuously dried, so that the drying effect is more uniform and the drying efficiency can be effectively improved; furthermore, through arrangement of a suction passage on the top surface of the box body, the heat of exhaust gas can be effectively recycled, so that fuel is saved.

Description

technical field [0001] The invention belongs to the technical field of crushed red tea production equipment, and in particular relates to an energy-saving crushed red tea production line which is convenient for maintenance. 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...

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.
