CONTROLLED MOISTURE RELEASE HUMIDIFIER FOR USE WITH TOBACCO PRODUCTS

摘要

A humidifier for use with tobacco products comprises a gel body comprisin g a continuous porous network of particles supporting a volume of moisturisi ng liquid, the gel body configured to release the liquid by evaporation at a predetermined rate, and a permeable layer enclosing the gel body through wh ich the evaporated liquid may pass. The gel can be engineered to give an eva poration rate and hence moisture delivery rate that is suitable for a partic ular tobacco hydrating requirement. Examples of useful gels include alginate s and pectins. Additional modifying substances such as salts can also be inc luded for further tailoring of the evaporation rate.
