Abrégé

The present disclosure relates to a tobacco flavoring machine, comprising: a drum (1) capable of rotating about an axis thereof as a rotation center; a nozzle (6) disposed in the drum (1) to spray a liquid flavor to tobacco shreds in the drum (1); and a shoveling plate (5) arranged on an inner wall (11) of the drum (1) and extending from an inlet end of the drum (1) towards the interior of the drum (1), the shoveling plate (5) being disposed obliquely with respect to a generatrix (9) of the drum (1). The present disclosure improves the problem of the related art that tobacco shreds cannot flow smoothly from an inlet end toward an outlet end because a shoveling plate (5) is parallel to an axis of a drum (1).

A cigarette package airtightness testing device and method, wherein the testing device comprises: a chamber (1), which is configured to form a sealed space in which a tested cigarette package (a) is placed; an air duct (2), a first end of which is used for being in communication with the inside of the tested cigarette package (a), the connection with the tested cigarette package (a) being configured to form a seal, and a second end of which is arranged outside the chamber (1); a pressure sensor (3), which is used to detect the pressure in the chamber (1); a vacuum generation device (4), which is connected to the chamber (1) and configured to adjust and maintain the pressure in the chamber (1) within a preset pressure range according to the pressure value detected by the pressure sensor (3); and a flow meter (5), which is arranged on a pipeline connecting the vacuum generation device (4) and the chamber (1), and is used to display the flow value in the pipeline, so as to determine the airtightness of the tested cigarette package (a) according to the flow value when the pressure in the chamber (1) is within the preset pressure range. The testing device and method have clear testing indicators and high accuracy, and are used to alleviate the influence of poor cigarette package airtightness on cigarette quality.

The invention relates to a tobacco shred feeding treatment device and a method for improving the heat energy and feed liquid absorption efficiency of tobacco shred, comprising: a tobacco shred feeding machine, said tobacco shred feeding machine mainly comprises a roller, a process warm-air pipe, a power blower, a heater, a steam nozzle, a feed liquid nozzle and an air inlet pipe; the process warm-air is blown into said roller from said air inlet pipe via said steam nozzle and said heater under the action of said power blower, and mixed with the tobacco shred; said air inlet pipe is provided directly under the central axis of said roller; the opening of said air inlet pipe faces up obliquely, and the opening direction of which could be adjusted into any position within the roller according to the requirements; said steam nozzle is mounted between the power blower and the heater, to achieve heating the condensed water in the steam, and to avoid directly injecting the steam to burn the tobacco shred. Under the premise that it is not necessary to configure the tunnel heating and humidifying equipment, the process warm-air with steam can contact with the tobacco shred sufficiently to improve the heat energy and feed liquid absorption efficiency and uniformity.
