Embodiment 1

[0021] Add 10L of water to 1000g of tobacco stems, stir and heat-preserve and extract at 60°C for 1.5 hours, then press, filter, and centrifuge. The separated aqueous solution is micro-filtered with a ceramic membrane with a separation pore size of 5nm to remove impurities, and adjusted with ammonia water. The pH value of the extract is 7.5. 1mol / L potassium phosphate is used as the initial electrolyte in the concentration chamber, and the extract is introduced into the desalination chamber for electrodialysis treatment. With an initial current density of 40mA / cm 2 When the constant current operation is performed, the voltage drop of the membrane stack increases gradually with time. When the voltage reaches the maximum, the constant voltage operation is performed, and the conductance of the desalination chamber (tobacco extraction material liquid chamber) gradually decreases during the electrodialysis process, from the initial 63.8mS / cm dropped to 16.8mS / cm, electrodialysis r...

Embodiment 2

[0023] Add 10L of water to 1000g of tobacco powder, stir and heat-preserve and extract at 65°C for 2 hours, then squeeze, filter, and centrifuge. The separated aqueous solution is micro-filtered to remove impurities using a ceramic membrane with a separation pore size of 5nm. 1mol / L sodium sulfate is used as the initial electrolyte in the concentration chamber, and the extract is introduced into the desalination chamber for electrodialysis treatment. With an initial current density of 40mA / cm 2 When the constant current operation is performed, the voltage drop of the membrane stack increases gradually with time. When the voltage reaches the maximum, the constant voltage operation is performed, and the conductance of the desalination chamber (tobacco extraction material liquid chamber) gradually decreases during the electrodialysis process, from the initial 58.6 mS / cm dropped to 15.1 mS / cm, electrodialysis results. Cl-, NO 3 - and NO 2 - The removal rates can reach 92.1%, ...

Embodiment 3

[0025] Add 10L of water to the 1:1 mixture of 1000g of tobacco powder and tobacco stems, stir and heat-preserve and extract at 65°C for 2 hours, then squeeze, filter, and centrifuge. Filter to remove impurities. 1.5 mol / L sodium chloride was used as the initial electrolyte in the concentration chamber, and the extract was introduced into the desalination chamber for electrodialysis treatment. With an initial current density of 40mA / cm 2 When the constant current operation is performed, the voltage drop of the membrane stack increases gradually with time. When the voltage reaches the maximum, the constant voltage operation is performed, and the conductance of the desalination chamber (tobacco extraction material liquid chamber) gradually decreases during the electrodialysis process, from the initial 63.7 mS / cm dropped to 14.6 mS / cm, electrodialysis results. Cl - , NO 3 - , NO 2 - and SO 4 2- The removal rates can reach 90.1%, 92.7%, 97.4% and 91.8%, respectively.

Abstract

The invention discloses a regulation and control method for paper-making method reproducing tobacco leaf extract liquor negative ion components. Extract liquor of paper-making method reproducing tobacco leaf raw materials such as cabo, tobacco powder and low-grade tobacco leaves is processed through an ionic membrane separation technique. Contents of inorganic negative ions in the reproducing tobacco leaf extract liquor are adjusted to improve the quality of paper-making method reproducing tobacco leaves, and injurious ingredient contents of the paper-making method reproducing tobacco leaf smoke are reduced. The regulation and control method for the paper-making method reproducing tobacco leaf extract liquor negative ion components is a negative ion removing method which is simple in manufacturing technique, strong in controllability, high in selectivity , stable in quality, capable of being widely applied to the removing method for removing the inorganic negative ions in the paper-making method reproducing tobacco leaf extract liquor, and therefore combustion performance, sensory quality and smoke injurious ingredient releasing quantity of the paper-making method reproducing tobacco leaves can be improved.

Description

Technical field: [0001] The invention relates to a method for regulating anion components of an extract of reconstituted tobacco leaves by a papermaking method, and belongs to the technical field of production of reconstituted tobacco leaves by a papermaking method. Background technique: [0002] Papermaking reconstituted tobacco is a reconstituted tobacco produced by the basic papermaking process, which has the characteristics of fast burning rate, low tar release, high filling value and good processing resistance. The controllability of chemical components and physical parameters of reconstituted tobacco leaves is its most prominent advantage. At present, the regulation of reconstituted tobacco leaf components is mainly carried out through the selection of raw materials, biochemical treatment, pressure-driven membrane treatment, and the addition of functional components from external sources. However, these technologies have limited control capabilities, weak production op...
