Spray Dryer
The SPRAY FLUIDIZER System is the solution for making dust-free, free flowing, high density, compact granulates by solidification of solids from non-heat sensitive liquid feeds - be that solutions, suspensions, slurry or melt.

The demand for dry products in granular form is increasing. This is mainly owing to the fact that granules are non-dusty and easy to handle, thus enabling ever stricter environmental requirements to be met. By combining the spray drying and fluid bed technologies, GEA has developed a continuous process for producing granular products, i.e. the SPRAY FLUIDIZER. It is an efficient solution for the chemical industry in the production of high-strength products such as ceramic proppants, sulphate, chlorides organic salts and organic acids.
The SPRAY FLUIDIZER facilitates a continuous process where the desired mechanism of particle growth is layering and simultaneous drying of the liquid feed. It combines the spray drying and fluid bed technologies, as the evaporation starts when the liquid feed material is atomized and before the particles can adhere to the agglomerates or granulates of the fluidized powder layer in the Fluid Bed.
The feed is atomized by means of nozzles and sprayed into a fluidized product layer. The granules are continuously withdrawn from the Fluid Bed through a rotary valve maintaining a constant level of the fluidized layer. By subsequent screening, granules of desired particle sizes are discharged from the unit, while any oversized particles can be milled and recycled together with undersized particles and fines recovered in a Cyclone and/or Bag Filter Thus, all product material discharged from the plant will be of the desired particle size.
A plug-flow fluid bed is applied for second-stage drying and cooling.


HotSwirl, das neue indirekte Heizsystem von GEA, versorgt Sprüh- und Fließbetttrockner von GEA zuverlässig mit Heißluft – bei konstanter Menge und Temperatur.

The GEA CONTACT FLUIDIZER Fluid Bed is a compact, energy-saving industrial fluid bed drying platform for the largest bulk chemical powder applications.

Statische Fließbetten von GEA werden der Prozessindustrie zum Trocknen, Kühlen und Kalizieren von Pulvern, Kristallen und Granulaten verwendet.

Sowohl Nachtrocknung als auch Kühlung sind wichtige Schritte bei der Pulverherstellung. Das VIBRO-FLUIDIZER™ Fließbett ist für seinen Wirkungsgrad und seine schonende Verarbeitung bekannt – ganz gleich, ob es sich dabei um ein Feinpulver oder ein agglomeriertes Produkt handelt.

Thermoforming has long played a central role in food packaging. Now it is facing a major shift. As regulations tighten, materials evolve and costs rise, form fill seal lines must do more than run reliably – they now shape how food stays fresh, affordable and recyclable. Take a look at the key thermoforming trends informing the food packaging and delivery landscape.

Von den Obstplantagen am Kap bis in die Regale von 40 Ländern – das südafrikanische Verpackungsunternehmen Betko hat sein Geschäft auf Frische, zeitliche Präzision und Zuverlässigkeit aufgebaut. Dank der Kühltechnologie mit kontrollierter Atmosphäre von GEA kann das Unternehmen nun Äpfel und Birnen bis zu 14 Monate lang lagern und den Energieverbrauch um 20 % senken. All dies basiert auf einer mehr als 30-jährigen Partnerschaft.
