Problems solved by technology

However, this technology still has certain defects, such as the loss of water-insoluble components in tobacco during the pulping and papermaking process, the high pressure of wastewater treatment, and the poor sensory quality of reconstituted tobacco leaves, which leads to low raw material utilization and poor quality of tobacco leaves. Raw material resources are tight and the proportion of product usage is low

Embodiment 1

[0021] Put 5 kg of flue-cured tobacco powder raw materials with a moisture content of 60 mesh or more and a moisture content of 5% into a 24L extraction kettle, extract for 2 hours at 50°C under an extraction pressure of 300mPa, use 70% ethanol as an entrainer, and use 10 times the water and washed 3 times to get the essential oil.

[0022] After supercritical extraction, the tobacco powder raw material and tobacco stem are mixed according to the weight ratio of 5:5, and 80 kg of water is added, extracted at 60°C for 1 hour, and then the extract is separated from the solid residue by pressing, filtering, and centrifuging. The purified extract is vacuum-concentrated at a vacuum of 80mPa and a temperature of 60°C until the weight content of solids in the concentrate reaches 50%, and the essential oil obtained after washing with water is added to the concentrate to make a dip coating Liquid, essential oils account for 0.3% of the entire dipping solution by weight. After the soli...

Embodiment 2

[0025] Add 5 kg of minced Burley tobacco with a moisture content of 25% above 60 mesh into a 24L extraction kettle, and extract for 2 hours at 50°C under an extraction pressure of 350mPa. The extract in the separation tank is rectified under the rectification conditions of 150°C tower bottom temperature, 100°C tower top temperature, and a reflux ratio of 5. The supercritical fluid tobacco extract is rectified, and the essential oil of the tower overhead distillate is used for dipping liquid preparation. ;

[0026] After supercritical extraction, burley tobacco powder and tobacco stems are mixed according to the weight ratio of 5:5, and 80 kg of water are added, extracted at 60°C for 1 hour, and then the extract and solid residue are separated by pressing, filtering, and centrifugation. separate. The purified extract is vacuum-concentrated at a vacuum of 80mPa and a temperature of 60°C until the weight content of solids in the concentrate reaches 50%, and the essential oil obt...

Embodiment 3

[0029] Add 5 kg of flue-cured tobacco powder with a moisture content of 60 mesh or more and a moisture content of 12% into a 24L extraction kettle, use 80% ethanol aqueous solution as an entrainer, and extract at 50°C under an extraction pressure of 350mPa for 2 hours. The extract in the separation kettle was molecularly distilled at different temperature ranges under the conditions of rotor speed 300 r / min and material flow rate 70 mL / h, and the product essential oil in the temperature range of 40-60 °C was collected for dipping liquid preparation.

[0030] After supercritical extraction, flue-cured tobacco powder and tobacco stems are mixed according to the weight ratio of 5:5, and 80 kg of water is added, extracted at 60°C for 1 hour, and then the extract is separated from the solid residue by pressing, filtering, and centrifuging. The purified extract is concentrated in vacuum until the weight content of solids in the concentrate reaches 50% under the conditions of a vacuum...

Abstract

The invention discloses a method for producing paper-making reconstituted tobacco. The method comprises the following steps of extracting essential oil from a tobacco raw material through supercritical carbon dioxide fluid; obtaining the tobacco raw material which is subjected to extraction; transferring the tobacco raw material which is subjected to the extraction to a raw material extraction tank; mixing the tobacco raw material which is subjected to the extraction with tobacco stems; performing water extraction to obtain extract liquid and solid residue; concentrating the extract liquid and then adding the essential oil into the concentrated extract to obtain dip-coating liquid; preparing a film base from the solid residue by a paper-making process; and finally coating the dip-coating liquid onto the film base to obtain the reconstituted tobacco. The method is technically feasible and can be widely used for producing the paper-making reconstituted tobacco, and the product quality is easily controlled. By the method, the use ratio of the tobacco raw material can be improved, the burden of sewage discharge can be reduced, and the appearance and sensory quality of the paper-making reconstituted tobacco can be improved.

Description

Technical field: [0001] The invention relates to a manufacturing method of reconstituted tobacco leaves by papermaking method, in particular, using supercritical fluid to selectively select aroma components and moisturizing components of tobacco leaf raw materials, so as to reduce the loss of such components in the production process of reconstituted tobacco leaves by papermaking method, and improve the quality of papermaking method. A method for reconstituting the organoleptic quality and moisturizing performance of tobacco leaves. Background technique: [0002] Papermaking reconstituted tobacco has the characteristics of good processing resistance, remarkable coke reduction effect, and strong product quality plasticity, and has been widely used in the tobacco industry. At present, the raw materials of reconstituted tobacco leaves in the papermaking method are extracted with water to extract the soluble components. However, this technology still has certain defects, such a...
