Problems solved by technology

However, its equipment structure is complicated, especially the pressure-bearing sealing valves are installed in many places, which will bring more hidden dangers in production safety.
[0004] Chinese invention patent application 2006100983144 discloses another tobacco stem expansion method and equipment, in which steam airlocks are respectively set at the inlet and outlet of the pressurized steam treatment device to block the air flow, thereby realizing continuous tobacco stem expansion treatment, However, the equipment structure is still relatively complicated, and the air lock at the outlet may have an adverse effect on the instantaneous pressure release and expansion of the tobacco stem while blocking the airflow
[0005] In addition, the temperature of the expanded tobacco stem treated by the above two technical solutions is high, the moisture content is low, and the texture is loose, all of which have the problem of a high crushing rate of the expanded tobacco stem.

Embodiment 1

[0040] As shown in FIG. 2 , the tobacco stem online expansion processing equipment of this embodiment is mainly composed of a feed hopper 1 , a pressurization and heating device, and a Venturi expansion tube 7 . The feed hopper 1 is connected to the pressurization and heating device through the sealing valve 2. The pressurization and heating device is composed of a vertical pressure pipe 3 and a horizontal delivery pipe 6. The vicinity of one end of the horizontal delivery pipe 6 intersects with the pressure pipe 3. A screw conveyor 5 is installed in the pipe 6 . The superheated steam pipe 4 is connected to the pressure pipe 3 and the delivery pipe 6 respectively. The outlet of the delivery pipe 6 away from the pressure pipe is connected to the Venturi expansion pipe 7, and there is a sealing valve 8 in front of the nozzle in the expansion pipe 7. The discharge port of the Venturi expansion tube 7 is connected with a humidification resurfacing box 9 . When the tobacco stem e...

Embodiment 2

[0042] As shown in Fig. 3, the basic structure of the tobacco stem expansion processing equipment of the second embodiment is the same as that of the first embodiment, except that a sealing valve 8 is installed behind the nozzle in the Venturi expansion tube 7.

Embodiment 3

[0044] As shown in FIG. 4 , the difference between the tobacco stem expansion processing equipment in this embodiment and the first embodiment is that the feeding hopper 1 is directly connected to the conveying pipe 6 equipped with the screw conveyor 5 through the sealing valve 2 .

Abstract

The present invention provides an on-line expansion processing method of tobacco stem and its processing equipment. Said method includes the following steps: heating tobacco stem by using superheated steam and applying pressure to said tobacco stem, then releasing pressure to make the tobacco stem be expanded, and spraying water onto the expanded tobacco stem to make the expanded tobacco stem be moistened. Said processing equipment includes charging device, sealing valve, heating device, pressure-applying device, expansion treatment device and moistening device.

Description

technical field [0001] The invention relates to a tobacco expansion processing method and equipment used by cigarette manufacturing enterprises, in particular to a processing method and equipment for tobacco stem expansion treatment using saturated or superheated steam. Background technique [0002] At present, in order to reduce production costs and fully increase the utilization rate of tobacco stem materials, tobacco manufacturing enterprises usually obtain high-expansion tobacco stems or shredded tobacco by expanding the tobacco stem materials to increase the filling rate of tobacco products. [0003] Chinese patent application 200510118934.6 discloses an ESS (Expanded Shredded Stem) process for preparing granular expanded tobacco stems and the equipment used therein. The expanded tobacco stem equipment includes two superheated steam treatment sections, wherein the first treatment section is connected with the tobacco stem feeding device and is provided with a steam inje...
