Problems solved by technology

This process has well-known shortcomings such as dust and high noise. The most important problem is that the fine tobacco stems in the tobacco rods are also crushed into smoke powder during the crushing process, resulting in a decrease in the utilization efficiency of the tobacco rods, and the process cannot improve The quality and use value of cigarette sticks
[0004] For the pretreatment technology of traditional mechanical crushing tobacco sticks, there is no corresponding patent protection in China

Embodiment 1

[0018] Embodiment 1: as figure 1 Shown is the flow chart of the intermittent tobacco stick pretreatment process of the present invention, including intermittent microwave loose tobacco sticks, artificial thin tobacco stems and manual sorting of tobacco dust. Small-scale intermittent microwave processing equipment can be used for daily household appliance microwave ovens. Pay attention to controlling the microwave processing time to avoid scorching and other situations that are not conducive to the reuse of tobacco sticks due to excessive water loss in the tobacco sticks. Corresponding protective equipment should be worn during manual sorting, and a suitable screen should be selected for screening according to the size of the thin tobacco stems contained in the tobacco sticks. Its advantages are: low equipment cost, suitable for laboratory or small batch pretreatment process.

Embodiment 2

[0019] Embodiment 2: as figure 2 Shown is the flow chart of the continuous tobacco stick pretreatment process in the present invention, including continuous microwave loose tobacco sticks, vibrating sieve for sorting fine tobacco stems and tobacco dust. Continuous microwave treatment of tobacco sticks requires adjusting the power of the microwave generator according to the density and moisture content of the tobacco sticks, and controlling the microwave irradiation time by controlling the belt speed, so as to avoid situations that are not conducive to the reuse of tobacco sticks, such as burnt or not loosened. occur. Use a vibrating screen to sort the fine tobacco stems and tobacco powder. When screening, it is necessary to select a suitable screen according to the size of the fine tobacco stems contained in the tobacco rod, which can improve production efficiency and avoid unnecessary losses; or Choose air sorting machine for screening. The air sorting machine should be wel...

Embodiment 3

[0020] Example 3: The microwave pretreated cigarette sticks (samples 2 and 4) and traditional mechanically pulverized cigarette sticks (samples 1 and 3) were chemically analyzed, and the results are shown in Table 1.

[0021] Table 1. Chemical analysis of tobacco sticks prepared by two pretreatment methods

[0022]

[0023] As shown in Table 1, the total amount of total sugar, reducing sugar, and nicotine after microwave treatment increased compared with that of the mechanically pulverized sample, while the contents of harmful substances such as nitrate, nitrite, NNK, etc. were higher than those of the mechanically pulverized sample. The samples were reduced, indicating that the quality of the tobacco rods was improved after microwave treatment.

Abstract

The invention relates to a pretreatment process for reusing waste in the cigarette industry, specifically, using microwave equipment to irradiate the waste cigarette sticks in the cigarette industry, also known as "ash sticks", so that the smoke sticks are loose and broken and then finely smoked. The stems and tobacco powder are sorted to meet the needs of subsequent production and processing. Microwave irradiation can improve the quality of tobacco sticks, including the quality of smoking and killing harmful insects and bacteria in the tobacco sticks) The separation of thin tobacco stems and tobacco powder improves the availability of tobacco sticks. This process has little environmental burden and reduces Dust pollution and noise pollution in production. The present invention can perform intermittent and continuous processing, and is suitable for various production capacity demands.

Description

technical field [0001] The invention relates to a pretreatment process for reusing waste in the cigarette industry, specifically irradiating the cigarette sticks of the waste in the cigarette industry with microwave equipment, so that the sticks are loose and broken, and then the fine tobacco stems and tobacco dust are sorted. It meets the needs of subsequent production and processing, and belongs to the technical field of comprehensive utilization of tobacco waste resources. Background technique [0002] Tobacco sticks are tobacco powder and thin tobacco stems produced in the production of cigarettes, that is, formed by pressing tobacco veins, which have high density and hardness, and cannot be used directly in the recycling process. They need to be reduced to tobacco powder through a pretreatment process. Only then can it be used in production. [0003] Cigarette industry waste tobacco sticks, also known as "ash sticks", currently the existing pretreatment methods for tob...
