METHOD AND APPARATUS FOR DRYING A POROUS MATERIAL, BY INTERMITTENCE, IN WHICH THE DRYING PERIODS COINCIDE WITH THE INITIAL ACCESSIBILITY PERIOD OF DRYING

摘要

The invention relates to a method for drying a porous material for intermittently drying the core of the material, alternating periods of drying by air flow applied to the surface of the material and passive periods without drying by air flow. , characterized in that: - the drying periods by air flow are each carried out during a period Ta coinciding essentially with the period of initial accessibility of drying, the passive periods are each carried out for a period Tp during which the material has a percentage of moisture at the core greater than the percentage of moisture at the surface to tend towards a percentage of surface moisture equal to the percentage of moisture at heart
