Abstract
In this study, the effects of some processing parameters on moisture content, drying yield, bulk density, solubility and particle size of peppermint tea powders obtained from a hot bed spray dryer were investigated. In this method of drying, a heated bed is used instead of heated air to simplify spouted bed drying method and lower the cost of drying. A wheel rotary atomizer was employed for spraying of material and a frustum-shaped bed heated by thermal elements was applied around the atomizer. Independent variables were bed temperature (130, 140 and 150°C), feed flow rate (10, 20 and 30 L/h) and rotary speed of atomizer (7,000, 12,000 and 16,000 rpm). The moisture content of dried tea powders ranged from 3.13 to 4.87%. The highest drying yield (87.23%) and solubility (89.6%) were obtained at the bed temperature of 130°C and feed flow rate of 10 L/h.
