Drying device for reconstituting tobacco leaves through papermaking method and drying method thereof

Abstract

A drying device for reconstituting tobacco leaves through a papermaking method and a drying method thereof are disclosed. The method includes the steps of pulling 30 to 40 percent of coat sheet out from under that coating tank of the coating section by using a metal support net, and transferring to the rewinding machine, connecting the coated sheet of the metal support net and the metal support net to the rewinding pipe, the rewinding machine coiling the coated sheet and the metal support net into the rewinding sheet together, removing the rewinding sheet and placing the rewinding sheet into the sealed box body, after opening the heat exchanger to lower the temperature in the sealed box body to -10- -40 DEG C, closing the heat exchanger, waiting for all the rewinding sheets to freeze, andafter opening the heat exchanger to lower the temperature of the enclosed cabinet to-30--60 DEG C, then starting the vacuum pump to vacuum in the sealed box until the negative pressure is 15-50Pa, start the heating pipe for heating, waiting for 1-3 hour, taking out the drying rewinding and opening the supporting net, and cutting the drying thin slices. It will make the internal structure of the sheet loose and porous, which improves the sensory quality of tobacco sheet, and can significantly improve the aroma, harmonicity, irritating odor and aftertaste of tobacco sheet.

Description

technical field [0001] The invention relates to the field of papermaking reconstituted tobacco leaves, in particular to a papermaking method reconstituted tobacco drying device and a working method thereof. Background technique [0002] Paper-making reconstituted tobacco, also known as paper-making tobacco sheet, is a regenerated product that uses discarded tobacco stems, tobacco dust, and low-grade tobacco leaves in the cigarette production process as raw materials to make sheets or filaments through the same process as papermaking. The process is to use tobacco stems, tobacco powder and low-grade tobacco leaves as raw materials, after soaking and extracting, the extracted raw materials and the extract are separated, the extracted raw materials are added to the fiber and then beaten, and the substrate is formed by a paper machine. At the same time, the extract is condensed to form a concentrated solution, and flavors, fragrances and pigments are added to form a coating solu...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that part of the low-boiling aroma components will volatilize during the process of drying the coated sheet by the existing hot air drying method, which will lead to the waste and loss of the original aroma of tobacco, and finally affect the sensory quality of reconstituted tobacco leaves.
