Problems solved by technology

[0004] Due to the small size of soot particles below 60 mesh, if they participate in the manufacturing process of paper-making flakes together with the current tobacco stems, chips, and tobacco powder, a large amount will be lost, and it will also affect the normal papermaking of paper machines. Therefore, it is generally used in the production process of paper-making reconstituted tobacco This soot cannot be used in

Embodiment 1

[0016] Add 1 part of soot to 10 parts of water, stir and extract at 65°C for 40 minutes, dehydrate to 30% dryness through a filter press, discard the soot mud, and the extract enters the liquid storage tank, and then pumps it to the extraction tank for the second The second material is 1 part of soot, and it is also stirred and extracted at 65°C for 40 minutes, dehydrated to 30% dryness through a filter press, the extract is put into a liquid storage tank, and then centrifuged to remove the precipitate. The extraction liquid is needed, and the average relative extraction rate of the two parts of soot is 76%, which is added to the extract liquid of tobacco stems and chips at a ratio of 20%, and enters the production process of reconstituted tobacco leaves by the papermaking method.

Embodiment 2

[0018] Add 1 part of soot to 8 parts of water, stir and extract at 80°C for 60 minutes, dehydrate to 35% dryness through a filter press, discard the soot mud, and the extract enters the liquid storage tank, and then pumps it to the extraction tank for the second part Material extraction, the second material is 1 part of soot, also at 80 ° C, stirred and extracted for 60 minutes, dehydrated to 35% dryness through a filter press, the extract was put into a liquid storage tank, and then centrifuged to remove the sediment to obtain the required For the extract, the average relative extraction yield of the two parts of soot is 62%, which is added to the extract of tobacco stems and chips at a ratio of 10%, and enters the production process of reconstituted tobacco leaves by the papermaking method.

Embodiment 3

[0020] Add 1 part of soot to 5 parts of water, stir and extract at 50°C for 30 minutes, dehydrate to 25% dryness through a filter press, discard the soot mud, put the extract into the liquid storage tank, and then centrifuge to remove the sediment to obtain the desired The extract has a relative extraction rate of 60%, which is added to the extract of tobacco stems and chips at a ratio of 20%, and enters the production process of reconstituted tobacco leaves by the papermaking method.

Abstract

The present invention provides the recovering and treating process of tobacco dust produced in cigarette production, and features that the tobacco dust is extracted and the extracted liquid is further reformed into tobacco through a papermaking-like process. The extracting process has the technological parameters of: extractant / tobacco dust weight ratio of 5-10, extracting temperature 50-80 deg.c, extracting period 30-60 min and the water content of the dewatered extract 25- 35%. Recovering and treating the tobacco dust can lower production cost and utilizing the tobacco dust with relatively high cigarette scent component can raise the quality of the reformed tobacco.

Description

technical field [0001] The invention relates to the recycling of tobacco waste, in particular to a process for recycling the soot produced in the cigarette manufacturing process, which can be used as a raw material in the production process of reconstituted tobacco leaves by papermaking after processing. Background technique [0002] In the cigarette manufacturing process, a large amount of soot below 60 mesh will be produced. Currently, the soot below 60 mesh produced in the cigarette production process is generally treated as garbage, landfilled or incinerated, which not only causes certain pollution to the environment, It also causes a waste of resources. After analyzing the cigarette ash, it is found that it contains a large amount of cigarette aroma components, the content of which is equivalent to that of ordinary tobacco leaves, far higher than that of cigarette aroma components in tobacco stems, and has better utilization value. [0003] Papermaking reconstituted to...
