Embodiment 1

[0018] The method for controlling chlorine and nitrate content in tobacco extraction or extract is characterized in that: 10.00 kg of tobacco raw material extraction or extract in the production of reconstituted tobacco leaves by papermaking method is used, wherein the solid content is 70.5%, and the chlorine content is 1.62%. The nitrate content is 1.12%; dissolve it in 70.00kg of water and stir evenly, the concentration after dilution is about 8.8%; put the diluted solution into a nanofiltration membrane circulation device for circulation filtration, and the operating temperature is controlled at ≤40°C. The operating pressure is controlled at ≤ 35Mpa; 33.62kg of the retained solution after removal of chlorine and nitrate is obtained by the nanofiltration membrane, and its concentration is 19.3%; 9.67Kg of extract is obtained after the concentrated solution is concentrated, wherein the solid content is 66.5%. The content is 0.16%, and the nitrate content is 0.38%, which is use...

Embodiment 2

[0021] The method for controlling chlorine and nitrate content in tobacco extraction or extract is characterized in that: 10.00 kg of tobacco raw material extraction or extract in the production of reconstituted tobacco leaves by papermaking method is used, wherein the solid content is 65.9%, and the chlorine content is 1.67%. The nitrate content is 0.92%; dissolve it in 90.00kg of water and stir evenly, the concentration after dilution is about 6.6%; put the diluted solution into a nanofiltration membrane circulation device for circulation filtration, and the operating temperature is controlled at ≤40°C. The operating pressure is controlled at ≤ 35Mpa; 28.36kg of the retained solution after removing chlorine and nitrates is obtained by the nanofiltration membrane, and its concentration is 21.9%; 8.22Kg of extract is obtained after the concentrated solution is concentrated, wherein the solid content is 75.5%. The content is 0.08%, and the nitrate content is 0.32%. It is used as...

Embodiment 3

[0024] The method for adjusting and controlling chlorine and nitrate content in tobacco extraction or extract is characterized in that: 100.00 kg of tobacco stem raw material extraction or extract solution in the production of reconstituted tobacco leaves by papermaking method, wherein the solid content is 5.62%, and the chlorine content is 0.21% , the nitrate content is 0.14%; because its concentration has met the operating requirements of the nanofiltration membrane circulation device, it is directly put into a nanofiltration membrane circulation device for circulation filtration, and the operating temperature is controlled at ≤40°C and the operating pressure is controlled at ≤35Mpa; Obtain 28.36kg of retentate solution after removal of chlorine and nitrate intercepted by nanofiltration membrane, its concentration is 18.3%; after concentration of the retentate solution, 7.40Kg of extract is obtained, wherein the solid content is 70.1%, and the chlorine content is 0.26% , with...

Abstract

The invention relates to a method for adjusting and controlling the contents of chlorine and nitrate in a tobacco extract. The invention aims at solving the problems of complicated technique, relatively high cost, easily damaged original aromatic components in tobacco and chemical agent residue in the extract in adjusting and controlling the contents of the chlorine and the nitrate in the tobacco extract during the production of reconstituted tobacco leaves in the existing paper-process. The technical keys are as follows: the method is characterized in that a tobacco raw material extract used in the production of the reconstituted tobacco leaves in the paper-process is selected and the concentration thereof is adjusted and controlled to meet operation requirements, and then the extract is put into a nano filtration membrane circulating device for circulation and filtration and a trapped liquid with the chlorine and the nitrate removed and trapped by a nano filtration membrane is obtained; the trapping liquid is used as a material which is coated on and refilled into a substrate during the production of the reconstituted tobacco leaves in the paper-process, and a dialyzate containing high-content of the chlorine and the nitrate the salt of which is removed through reverse osmosis treatment, can be used for extracting process water or washing water of the nano filtration membrane and separating equipment, and the like.

Description

technical field [0001] The invention relates to a process for changing the content of chlorine and nitrate in tobacco, in particular to a method for adjusting and controlling the content of chlorine and nitrate in tobacco extraction or extract by using nanofiltration membrane separation technology. It is suitable for the production of reconstituted tobacco leaves by papermaking method. Background technique [0002] Tobacco contains a small amount of chlorine, and excessive chlorine content will deteriorate the flammability of cigarettes. Generally, when the chlorine content is higher than 0.6%, the hygroscopicity of the tobacco leaves will be increased and the combustibility will be reduced; when the chlorine content exceeds 1.0%, the burning speed of the tobacco leaves will be slowed down, gray and black, and the fire holding power will be weakened; when it exceeds 1.5%, significant flame retardancy will appear. The fire holding power of cigarettes is weakened, and even th...
