The capacity of a spray dryer is the amount of water evaporated within the dryer. The evaporation is directly correlated with the temperature drop across the dryer. The greater the difference between the inlet temperature and the outlet temperature, the more water is evaporated. In order to optimize the capacity, the inlet temperature of the dryer should be as high as possible (within the constraints of the product being dried) and held constant. This also improves the energy efficiency of th... Read More
