Abstract

A particle mat for pressing into a pressed board is heated by concurrently passing through the mat treatment air coming from an air-conditioning system and having a predetermined moisture content and dew point, heating the treatment air passing through the mat to a temperature which is greater by a dew-point differential than the dew point of the treatment air, and controlling the volume rate of flow of the treatment air and the moisture content of the treatment air such that the mat is preheated to a predetermined temperature while liquid in the treatment air is allowed to condense in the mat to at most a maximum liquid content.
