MSD® 喷雾干燥器

MSD® 喷雾干燥器是多阶段喷雾干燥器，它的三阶段干燥流程综合了喷雾和流化床干燥技术，可为最佳的整体干燥效率和产品质量提供保障。

一组喷嘴将浓缩物雾化并将其送入干燥室。干燥气体从垂直方向高速进入空气扩散器，确保雾化浓缩物能实现优化混合。这一阶段，在高冲力液滴通过干燥室的同时，将实时进行蒸发。干燥室和气流的设计可以阻止颗粒粘在干燥室壁上，它们将直接进入干燥室底部的集成流化床进行第二阶段干燥。最后，粉末进入 VIBRO-FLUIDIZER® 流化床进行最后阶段的干燥和冷却。

干燥气体从干燥室顶部离开，这样，干燥气体中的极细颗粒与喷嘴喷射出来的喷雾发生碰撞时，可以形成优质的二级复聚物。排出的气体通过 SANICIP™ 袋式过滤器，气体中包含的剩余颗粒会被分离出来。该袋式过滤器滤出的极细颗粒将会返回到干燥室 - 它会根据对复聚物的要求返回到静态流化床或喷嘴。如果不需要复聚状粉末，极细颗粒将直接进入 VIBRO-FLUIDIZER® 流化床。

MSD® plant upgrades

We want all of our customers to get great results from their GEA spray dryer, from day one, and also for the lifespan of their plant. We’re always striving to develop new technologies that can improve your plant’s productivity, safety and efficiency, as well as support process sustainability goals.

Hygiene and safety, 24/7 

The MSD® spray dryer is hygienic by design to meet the most stringent regulatory requirements for safe, sanitary dairy processing. You’ll also find user-friendly features for easy equipment inspection and maintenance. Equipment safety and operational health and safety are key factors in the design of all GEA spray dryer components, plants and process lines. Key technologies, including our SPRAYEYE®, Clean Purge, DRIVENT®, COTECTOR® and fire safety systems are all designed to give you confidence in the safety of your MSD® spray dryer plant, monitoring for fire and explosion risks, while supporting 24/7 production.

All MSD® systems are supplied with automated clean-in-place (CIP) units, reducing the need for manual cleaning tasks. CIP can potentially reduce water and chemicals use, and so cut wastewater volume and associated treatment.

A focus on efficiency and quality

MSD® spray dryer efficiency and quality is further enhanced thanks to our Clean Purge and CEE cyclone technologies integrated into the plant. We’ve shown that compared with other air dispersers, the GEA DDD® air disperser provides best-in-class distribution of the drying air. Benefits include a more uniform product and longer production runs between scheduled cleaning stops, which can lead to improved equipment performance overall.

Our SANICIP® II bag filter and the No Intervention Fines Return System (NIFRS) further help to reduce product loss and can lead to real improvements in productivity and final powder quality.

Focus on process stability and sustainability

The MSD® spray dryer can be combined with key GEA innovations that could significantly improve your process sustainability. Take a look at our digital GEA OptiPartner advanced process control platform, heat recovery systems and energy-saving AddCool® heat pump technology, which in combination can dramatically improve process stability and energy efficiency. Just talk to your local GEA representative to find out more.

Thorough testing before investing

We want you to be confident that our technologies will deliver on your expectations. At our test center of excellence in Soeborg, Denmark, you can trial your processes on MSD® equipment, and get expert help from GEA spray drying specialists who will work with you to refine and optimize processes and address any concerns and questions, before you invest. You can also see the latest GEA innovations in action, and evaluate the best options for your plant, not just for today, but with a view to your continued growth and expansion.
