Centrifugal dewatering drying device and drying method for tobacco leaves

Abstract

The invention discloses a centrifugal dewatering drying device for tobacco leaves, which comprises a machine base, wherein a sieve basket is arranged in a cavity formed by the machine base and an upper cover; a material distributing cone is fixedly arranged at the top of the sieve basket; a feeding cover is arranged above the material distributing cone; the sieve basket is fixedly connected with a central shaft through the material distributing cone; a spiral scraper arranged in the sieve basket is fixedly connected with a rotor shaft; a sieve basket driven gear is fixedly arranged on the central shaft; a scraper driven gear is fixedly arranged on the rotor shaft; a motor is used for driving a middle shaft to rotate through a belt driving pair; the middle shaft is used for respectively driving the sieve basket and the spiral scraper to rotate. According to the invention, the tobacco leaves are dried through centrifugal dewatering, so that the large dewatering problem of the tobacco leaves is solved, the moisture content of the tobacco leaves is reduced from 130% to about 50%; the feeding and discharging can be continuously performed; the tobacco leaves after dewatering are loosened and are not caked, so that the technical requirement of subsequent process and re-drying of the tobacco leaves is met. The invention also discloses a centrifugal dewatering drying method for tobacco leaves.

Description

technical field [0001] The invention relates to tobacco leaf processing equipment of a tobacco shred production line, in particular to a centrifugal dehydration and drying device for tobacco leaves. The invention also relates to a method for centrifugal dehydration and drying of tobacco leaves. Background technique [0002] The raw material of tobacco shredded production line is tobacco leaves, which are usually divided into three parts from top to bottom: upper tobacco leaves, middle tobacco leaves and lower tobacco leaves. Among them, the quality of the middle tobacco leaves is the best, the upper tobacco leaves are better, and the lower tobacco leaves are poor. However, the domestic upper tobacco leaves are not mature enough, the leaf structure is tight, the internal chemical composition is uncoordinated, the miscellaneous gas is heavy, and the smoke quality is poor; availability. At present, the upper tobacco leaves and the lower tobacco leaves are only used as season...
