Abstract: The purpose of this research is to study and investigate the hot air flow fixed granular bed drying of calcium. The main disadvantage of the fluidized bed drying process is the fine dust particle's formation, resulting in the loss of product at the filters. Moreover, dangerous explosion can occur by scrubbing between the granules. Cleaning of the fluidized bed dryer is another difficult and time consuming. In this work, the effects of velocity and temperature of the hot air to the drying rate at the different size of granule are studied to determine the optimal condition of the drying process. In this drying process, the moisture on the surface and inside the calcium granules are different. Since the moisture of the top layer of the granule calcium is different than that of the bottom layer, the optimal thickness of the layer of the granule calcium needs to be determined before operating the drying process After the drying process at different condition was performed, the moisture of the granule was measured and compared with that of the convention fluidized bed process. It was evident that the proposed drying process had higher drying rate and less dust diffusion than that of the conventional process. Additionally, this drying process was productive when the thickness of the layer of the granule was appropriate. Therefore, the air flow through the dryer was an appropriate drying process for granule calcium.
