Abstract
The invention relates to a process for collecting dispersed plant material particles during the formation of a reconstituted plant material, such as a reconstituted tobacco material. The process involves extracting components from a plant material using a solvent having an aqueous character. As such, an aqueous plant material extract and a water insoluble tobacco portion are provided. At least a portion of the aqueous extract is separated from the insoluble portion. The insoluble portion is formed into a desired shape (e.g., a sheet-like shape). Excess solvent is removed from the formed insoluble plant portion. The removed solvent has plant material particles dispersed therein and is collected. A portion of the excess solvent is removed from the dispersed plant material particles. The dispersed plant material particles are then collected.
