Spray Congealing Units
The Kreber spray congealer is an all-in-one solution for transforming molten materials into solid powders with enhanced functional characteristics, including increased solubility or encapsulation of active ingredients.
Operating from a melt-in to powder-out battery limit, the Kreber spray congealers handle all necessary processes within the equipment itself, such as cooling, emission treatment, and reintroduction of the cooling medium (e.g., air, nitrogen, or other gases). This closed-loop configuration ensures near-zero emissions to the environment. Our spray congealing equipment is designed to be flexible, low-maintenance, and scalable, supporting capacities of up to 15 tons per hour.
Full Package Overview
An overview of our full package for a Spray congealing unit
The atomizer nozzle breaks up the melt or slurry in small pre-defined droplets.
Inside the cooling chamber the droplets are contacted with a co-current gas cooling stream, allowing for rapid solidification.
The product is caught in a product cyclone, allowing for easy collection of the powder.
A bag filtering section is used to clean up any remaining particles from the air stream.
Just prior to re-introduction in the spray chamber, the cooling medium is cooled back to its operational temperature, allowing for closed loop operation.
Special options include ATEX equipment, encapsulation options, different cooling media.
