Abstract
This work discusses the evaluation of multi-stage adsorption dryers with air dehumidification by zeolite and alumina pillared clay. In a multi-stage dryer, product is dried in succeeding stages while air leaving a stage is fed to the next stage after dehumidification by an adsorbent. Energy efficiency of the drying system is evaluated for low-temperature drying (10-50°C) and compared with conventional condenser drying. Results showed that the efficiency of the multi-stage adsorption dryers increases with the number of stages. For low drying temperatures, zeolite is most favorable; for drying temperatures 40-50°C, alumina pillared clay needs less cooling and deserves preference.
