This R&D project will focus on microwave-assisted drying for nanosize particles. On the previous phase,**satisfactory results were obtained for microwave-assisted drying using multi-mode system at lab scale. For this**R&D project application of single-mode microwave system will be investigated and the performance of**single-mode and multi-mode systems will be compared.**Also detail technical analysis will be done on the operational parameters of microwave-assisted drying with**respect to technical requirements and specifications of an industrial microwave system. For this purpose, the**technical feedback of an industrial microwave manufacturer will be concerned. Besides, an investigation will**be carried out on microwave-assisted drying of raw material before ball milling. For ball milling operation a**minimum amount of moisture is needed, and microwave system can be used instead of conventional drying**systems.**Argex Titanium Incorporated, is developing a novel technology for producing titanium dioxide pigment**including preheating and dewatering. Therefore, low power microwave-assisted heating can be used for**preheating and dewatering. The main advantage of microwave treatment is selective heating due to material**type and size. In addition, reduction in energy consumption and process time would increase profit for pigment**production.

这个研发项目将专注于微波辅助干燥纳米颗粒。在前一阶段的基础上，利用多模系统在实验室规模上进行微波辅助干燥获得了满意的结果。本次研发项目将研究单模微波系统的应用，并对单模和多模系统的性能进行比较。**还将根据工业微波系统的技术要求和规格，对微波辅助干燥的操作参数进行详细的技术分析。为此，将关注某工业微波制造商的**技术反馈。此外，还将对球磨前原料的微波辅助干燥进行研究。对于球磨操作，需要最少的水分，微波系统可以代替传统的干燥系统。**Argex钛公司正在开发一种生产二氧化钛颜料的新技术**，包括预热和脱水。因此，低功率微波辅助加热可用于**预热和脱水。微波处理的主要优点是根据材料类型和尺寸选择性加热。此外，降低能耗和工艺时间将增加颜料生产的利润。
