OptimaDry mixing and drying system combines fluidizing blending technology with accurate and controlled microwave heating technology to achieve exceptionally homogeneous blends while gently and efficiently heating or drying a material. System’s benefits include faster processing times, uniform and consistent heat distribution and highly accurate temperature control compared to other technologies. System is suitable for large-scale industrial heating and drying of a wide range of applications, including herbs, spices, coffee, powders, nutraceuticals, plastics, chemicals and other materials where heat sensitivity is a factor and where aroma, color, nutrition or consistency must be maintained. Units are available in working capacities from 1.5 to 400 cubic feet. System’s microwave generators are either magnetron or solid state, with operating frequencies ranging from 896 to 928 megahertz and are modular, scalable and easy to maintain.
