Permeable element based vaporization process and device

摘要

The present invention is a method for vaporizing concentrate that will substantially eliminate general or localized burning of concentrate during the vaporization process and a device adapted for carrying out said method. The vaporization method is based on heating concentrate that has been absorbed into a frit, preferably fitted glass. Fritted glass is characterized by open-pore interstices that allow free passage of fluid through the frit. It is commonly used as a filtering element, particularly in high-temperature applications. It was discovered that concentrate placed in contact with fitted glass is absorbed through capillary action. Although room temperature concentrate may not readily seep fully into fritted glass, as concentrate is heated its viscosity is reduced such that it is readily absorbed by the fitted glass.
