The energy efficiency of infra-red drying is much lower, only 40 %, which means higher energy consumption and more costs. Energy savings are 50 % compared to infra-red drying. Air dryers are also environmentally friendly - 50 % less fuel is burned and CO2 produced. In addition, air dryers require much less maintenance time and costs and offer higher evaporation capacity.
