Spray dryer MSD®

Lo spray dryer MSD® è uno spray dryer multistadio che combina la tecnologia di spray drying e di essiccazione a letto fluido in un processo in tre fasi per assicurare la massima efficienza generale di essiccazione e qualità del prodotto.

Una serie di ugelli atomizza il concentrato e lo alimenta alla camera di essiccazione. Attraverso il dispersore, l'aria di essiccazione entra verticalmente ad alta velocità, garantendo una miscelazione ottimale con il concentrato atomizzato. In questa fase, l'evaporazione avviene all'istante durante il passaggio delle gocce attraverso la camera di essiccazione. La camera di essiccazione e il flusso d'aria sono stati progettati per evitare che le particelle aderiscano alla camera di essiccazione, conducendole direttamente nel letto fluido integrato sul fondo della camera di essiccazione, dove si svolge la seconda fase. Infine, la polvere viene scaricata all'interno di un letto fluido VIBRO-FLUIDIZER®, dove avvengono l'essiccazione e il raffreddamento finali.

L'aria di essiccazione fuoriesce dalla sommità della camera, producendo così una seconda agglomerazione molto ben definita grazie alle particelle fini contenute nell'aria di essiccazione che si scontrano con lo spray proveniente dagli ugelli. L’aria di scarico attraversa un filtro a sacco SANICIP™ che separa le restanti particelle presenti nell’aria. Le polveri fini scaricate dal filtro a sacco vengono riconvogliate nella camera di essiccazione, nel letto fluido statico o negli ugelli, a seconda dell'agglomerazione richiesta. Se sono necessarie polveri non agglomerate, le particelle fini vengono condotte direttamente al letto fluido VIBRO-FLUIDIZER®.

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.
