A method is described for enhancing mass and heat transport of fluids in a fine pore structure through an appropriate modulation of the fluid pressure. For example, in an air drying process for a porous material that contains liquid, the air pressure is modulated throughout the volume of the drying chamber. Alternatively, the fluid pressure is modulated in a process stream. As an example, this method can be used for rapid drying of any open porous substances ranging from small pored materials such as aerogels and xerogels, to larger pored substances or articles such as industrial articles, agricultural articles (e.g., densely stacked vegetables, coffee beans, hops and other grains), paper-based products, thin, films, pharmaceuticals, cloth, and clothing.
Procédé pour améliorer le transport de masse et de chaleur des fluides dans une structure poreuse fine par le biais de la modulation de la pression fluidique. Ainsi, dans un processus de séchage à air pour un matériau poreux qui contient un liquide, la pression de l'air est modulée à travers le volume de la chambre de séchage. En variante, la pression fluidique est modulée dans un flux de processus. Dans un exemple, ce procédé peut s'utiliser pour le séchage rapide de n'importe quelle substance poreuse ouverte, des matières poreuses à faibles tailles telles que les aérogels et les xérogels, jusqu'aux substances et articles poreux tels que les articles industriels et d'agriculture (p.ex., des légumes, des fèves de café, du houblon et d'autres grains densément empilés), des produits à base de papier, des films minces, des produits pharmaceutiques, des tissus ou des vêtements.
