Definitions

• the rolling method is known to be particularly suitable for reconstituted tobacco raw materials that contain less than 50% moisture by volume.
• the kneaded reconstituted tobacco raw material is rolled and molded with rotating rollers, the thickness is adjusted, and then it is dried in a separately installed dryer.
• the papermaking method is known to be particularly suitable for reconstituted tobacco raw materials that contain 80% or more moisture by volume.
• the fluid of the reconstituted tobacco raw materials is continuously spread on a liquid-permeable conveyor belt, and after the moisture is removed and the material is made to the desired thickness by compression rollers, it is dried in a separately installed dryer.
• One of the objectives of the present invention is to provide a new method for producing reconstituted pressure-molded tobacco sheets.
• a tobacco raw material with an increased amount of aerosol generation can be produced.
• the aerosol source may include, for example, one or more selected from the group consisting of glycerin and propylene glycol.
• the additive may also include, for example, a liquid flavoring. The inclusion of the liquid flavoring in the liquid raw material can impart flavor to the tobacco sheet.
• the above manufacturing method may include a step of supplying the raw materials mixed in the second step to an extruder, and a step of further adding a second liquid raw material to the raw materials supplied to the extruder.
• the second liquid raw material may contain one or more selected from the group consisting of water, glycerin, propylene glycol, a binder solution, and a liquid flavoring.
• a method for producing a reconstituted pressure-molded tobacco sheet includes a first step of feeding a first liquid raw material into a mixer, a second step of feeding a powder raw material containing at least tobacco into the mixer after the first step and mixing it with the first liquid raw material, and a molding step of molding the raw material mixed in the second step into a pressure-molded sheet.

Therefore, according to the fourth aspect, the moisture content of the raw materials can be adjusted in the extruder, so the amount of the first liquid raw material mixed in the mixer can be reduced. As a result, the raw materials can be prevented from becoming too viscous in the mixer, making it easier to handle the raw materials when they are supplied from the mixer to the extruder.
