FSD Minor™ Spray Dryer

The FSD Minor™ Spray Dryer is the smallest in a series of FSD™ Spray Dryers for R&D and small-volume production. It produces a coarse, agglomerated, free-flowing and dustless powder.

With an integrated fluid bed at the bottom of the drying chamber, the FSD™ Spray Dryers combine spray and fluid bed technology into a robust process where drying and agglomeration take place in one single operation. The particle structure thus obtained is comparable to a bunch of grapes. This technology is especially well-suited for food applications, including sticky, hygroscopic, aromatic and heat-sensitive products.

The drying process

In the preliminary drying stage the concentrate is atomized by co-current nozzles placed in the drying air duct. The air enters the spray dryer vertically through the air disperser at high velocity, ensuring optimal mixing of the atomized droplets with the drying air. Evaporation is instantaneous taking place during the vertical passage down the drying chamber. In this first-stage drying, the particles will not be completely dried.

At high moisture contents, the powder will exhibit high thermo plasticity and become very sticky. However, the air flow in the FSD™ spray dryer is designed to prevent particles from sticking to the drying chamber leading them directly to the integrated static fluid bed for second-stage drying. If the carbohydrate and/or fat contents of the powder are high, cold air will be used to pre-cool the product. The integrated static fluid bed is supplied with air at a velocity sufficient for fluidizing the product and for adapting the temperature for the second stage drying. The drying air from both primary and second-stage drying leaves the chamber from the top.

Agglomerated powders are in high demand as they will frequently have improved flowability and dispersibility compared to fine powders; and, moreover, they are less dusty.

Dear partners,

We would like to inform you that in the framework of preventive measures aimed at effectively addressing the spread of “Covid19” disease and in accordance with the National Public Health Organization guidelines (https://eody.gov.gr/), our company is committed to ensure public health, safety of its partners and employees. Therefore we have recommended the fulfillment of our employees' tasks through teleworking.

The duration of this measure is initially set from 17.03.2020 to 30.04.2020

The design provides full operation, but due to special conditions, delays in specific tasks or communication may occur.

Our company will strive to keep its operation uninterrupted and secure by serving its clientele in ways and timeframes that are judged possible.

We thank you for understanding and we remain at your disposal.


Αγαπητοί Συνεργάτες,

Θα θέλαμε να σας ενημερώσουμε ότι στο πλαίσιο μέτρων πρόληψης με σκοπό την αποτελεσματική αντιμετώπιση εξάπλωσης του κορωνοιού και σύμφωνα με τις οδηγίες υγιεινής & ασφάλειας που έχει ορίσει ο ΕΟΔΥ (https://eody.gov.gr/), η εταιρία μας για να διασφαλίσει τη δημόσια υγεία, την ασφάλεια των συνεργατών και των εργαζομένων της, συστήσαμε την εκπλήρωση των καθηκόντων των εργαζομένων μας, μέσω τηλεργασίας.

Η διάρκεια του συγκεκριμένου μέτρου ορίζεται αρχικά από τις 17.03.2020 έως τις 30.04.2020
