Abstract
Method of drying a medium for producing a porous matrix from a solution, a paste, an extract, a granulated material or such, where a liquid inert agent is fed into a vessel ( ) at controlled pressure and amount through a valve ( ), transferring the pressurized liquid inert agent to a mixing vessel ( ), said mixing vessel ( ) also receiving the solution, such as paste, extract or granulated material, through an inlet valve ( ), adjusting the pressure and temperature inside the mixing vessel ( ) to desired levels by a release valve ( ), upon complete mixing of the inert agent with the solution, the mixture is expanded into a porous matrix and injected into a drying circuit through a drying chamber ( ), the matrix thereby being kept suspended in the drying chamber by the flowing drying medium, supplied by the blower ( ), the matrix moisture being removed from the mixture through a heat exchanger coil comprising a first heat exchanger ( ) where the water vapour is condensed and removed from the circuit and finally the drying medium is adjusted to the desired inlet condition in a heat exchanger ( ) before the drying medium flows through the matrix and the process is repeated.
