MSD® 噴霧乾燥機

MSD® 噴霧乾燥機は、噴霧流動床乾燥技術を 3 段階の乾燥工程と組み合わせて、最高の乾燥効率と製品品質を確保する多段式噴霧乾燥機です。

一連のノズルにより濃縮液が霧化され、その霧化液は乾燥室に供給されます。乾燥空気は、高速で空気分散機を介して乾燥室に垂直に入り、霧化濃縮液との最適な混合を確保にします。この段階では、蒸発は液滴が乾燥室を通過する際に瞬時に行われます。この乾燥室と空気流は、粒子が乾燥室の壁面に付着するのを防ぐとともに、第 2 段階の乾燥処理のために、乾燥室底部の一体型流動床に粒子を直接導くように設計されています。最後に、粉末は VIBRO-FLUIDIZER® 流動床に導かれ、最終的に乾燥・冷却されます。

乾燥空気は乾燥室の上部から出るため、乾燥空気中の微粒子とノズルから噴霧される霧化濃縮液との衝突時に、非常に明確に定義された二次凝集/造粒が可能になります。排出空気は、空気中に含まれた残存粒子を分離する SANICIP™ バッグフィルタを通過します。バッグフィルタから排出される微細粒子は、望まれる造粒に応じて、乾燥室内の静的流動床またはノズルにいずれかに戻ります。非造粒粉末が必要な場合は、その微細粒子は直接 VIBRO-FLUIDIZER® 流動床に導かれます。

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.
