Problems solved by technology

[0004] The prior art discloses a process for making tobacco stem granules. The process obtains tobacco stem granules through the process of microwave stem expansion treatment-tobacco stem granulation-remoisture treatment-stem flavoring-stem storage granules, but after granulation The moisture regain treatment process does not propose a moisture regain method, but the existing moisture regain method is used to rehydrate the tobacco stem particles, the tobacco stem particles are easy to stick, the moisture regain is uneven, and the moisture regain efficiency is poor

Embodiment 1

[0052] (1) Loading: Take 200 kg of tobacco stem particles with a particle size of 20 meshes, transport them to the moisture regaining chamber through a conveyor belt conveyor, and then seal the cavity of the moisture regaining chamber to keep the moisture regaining chamber in a sealed state.

[0053] (2) Vacuuming: Use a vacuum pump to evacuate the above-mentioned airtight resurgence chamber. When the pressure in the resurgence chamber is -0.07MPa, close the valve of the vacuum pump to stop vacuuming.

[0054] (3) Humidification and regaining moisture: Introduce 0.3MPa saturated steam into the dampening chamber for humidification and regaining moisture. When the pressure in the dampening chamber is -0.02MPa, stop feeding the saturated steam, and then continue to maintain moisture regaining under the constant pressure of -0.02MPa 2 minutes.

[0055] (4) Unloading: Open the pressure relief valve of the moisture resurfacing machine, after the moisture resurfacing chamber is depre...

Embodiment 2

[0058] (1) Loading: Take 200kg of tobacco stem particles with a particle size of 40 meshes, transport them to the moisture resurgence chamber through a conveyor belt conveyor, and then seal the cavity of the moisture resurgence chamber to keep the moisture resurgence chamber in an airtight state.

[0059] (2) Vacuuming: use a vacuum pump to evacuate the above-mentioned airtight moisture regaining chamber, and when the pressure of the moisture regaining chamber is -0.08MPa, close the valve of the vacuum pump to stop vacuuming.

[0060] (3) Humidification and regaining moisture: enter 0.35MPa saturated steam into the dampening chamber for humidification and regaining moisture. When the pressure of the dampening chamber is -0.025MPa, stop feeding the saturated steam, and then continue to maintain the dampening at -0.025MPa constant pressure for 2.5 minute.

[0061] (4) Unloading: Open the pressure relief valve of the dampening machine, release the pressure in the dampening chambe...

Embodiment 3

[0064] (1) Loading: Take 200kg of tobacco stem particles with a particle size of 60 mesh, transport them to the moisture regain chamber through a conveyor belt conveyor, and then seal the cavity of the moisture regain chamber to keep the moisture regain chamber in a closed state.

[0065] (2) Vacuuming: Use a vacuum pump to evacuate the above-mentioned airtight resurgence chamber. When the pressure in the resurgence chamber is -0.09MPa, close the valve of the vacuum pump to stop vacuuming.

[0066] (3) Humidification and regaining moisture: pass 0.4MPa saturated steam into the dampening chamber for humidification and regaining moisture, and when the pressure of the dampening chamber is -0.03MPa, stop feeding the saturated steam, and then continue to maintain moisture regaining under the constant pressure of -0.03MPa 3 minute.

[0067] (4) Unloading: Open the pressure relief valve of the dampening machine, release the pressure in the dampening chamber, and remove the tobacco st...

Abstract

The invention discloses a moisture regain method of tobacco stem particles, comprising the sequential steps of charging, evacuating, introducing saturated steam, moisturizing to regain moisture, and discharging. According to the moisture regain method of tobacco stem particles, a moisture regain room that is charged with material is evacuated to a set value, saturated steam is then introduced into the moisture regain room, tobacco stem particles regain moisture fully and evenly in vacuum state, the tobacco stem particles regained moisture have uniform moisture, and the moisture regain efficiency is high; cellular cavities in the tobacco stem particles are enlarged, the features of the particles as a macroporous adsorbing material are enhanced, good adsorbing capacity is provided, scorch smell of the tobacco stems can be removed effectively, smoke is elegant and fine, the tar and CO discharges are decreased effectively, and internal quality of the tobacco stem particles is improved.

Description

technical field [0001] The invention relates to the technical field of processing tobacco stem granules, in particular to a moisture regaining method for tobacco stalk granules. Background technique [0002] Tobacco stems are an important part of tobacco leaves, and after separation of stem leaves, tobacco stems accounting for about 25% of the total weight of tobacco leaves can be obtained. Tobacco stems are hard and tough. During the cultivation and growth of tobacco, they can transport nutrients and water. Therefore, the chemical components they contain are basically the same as those of leaves, but their effective content is not as good as that of leaves. [0003] In recent years, the application of tobacco stem particles as a new type of cigarette filter rod material in cigarette products has been increasing. It can mainly modify the mainstream smoke of cigarettes and effectively filter out harmful components in the smoke. Therefore, it is widely used in the entire indus...
