A Study on Spray Dried Gelatine: Effect of Feed Concentration

The objective of this study was to study the performance of a pilot-scale spray dryer and observed the effect of feed concentration during spray drying of gelatine. The spray drying conditions were manipulated in terms of feed concentration, inlet temperature and feed flow rate. In all experiments, the atomizer rotation and air flow rate were fixed at 23500 RPM and 66 m3/h. The result showed that if feed concentration of gelatine solution 10 and 15% (w/v), the product in the form of powder would not be obtained. So, the feed concentration 5 and 6% was chosen to analyze the powder of gelatine from spray drying. The quality of spray dried gelatine was compared with the Industrial Food Grade gelatine (bloom strength 151-160).
