WebDrying system incorporating a dehumidification cycle have been developed that both conserve energy and handle the material gently. The dryer operates using a heat pump where both sensible and latent heats are recovered from the exhaust air. The heat is then recycled back through the dryer by heating the air entering the dryer. WebJan 1, 2014 · 7.1 Introduction. Drying of building material has a long history since it has been found very long ago that drying could be used to convert clay into a useful building material. Drying processes are still nowadays an important step in the processing of building materials.
