Whether coating base powder particles for taste masking, improvement of flow characteristics, protection of core particles, controlled release effect or controlled dissolving time, the Hosokawa Turbulizer horizontal paddle mixer with its fully adjustable paddles is flexible in operation to suit most process requirements.
The fine coating of a chemical or a mineral with a 0.5 to 3% melt, where the primary particle size is in the range of a few microns, for example, is typically achieved using a powder melt.
The base product as well as the powder melt are gravimetrically fed at room temperature to the product inlet.
The powders are blended into a homogeneous mixture within the Hosokawa Turbulizer.
The jacketed vessel heats the powdery melt up to slightly above its melting temperature, jacket temperatures up to 3200C are achieved with hot oil for this application, although steam at 16 bar(g) can also used.
Product residence time within the Hosokawa Turbulizer is a mere 5 seconds (approx) during which the base product is coated with the melt.
Product discharge temperatures are typically 650C for this type of application.
The Hosokawa Turbulizer offers effective fine layer coating, solids-solids mixing and dispersing of liquids on solids, for a wide range of products as well as heating/cooling of powdery products, continuous reacting of gases with powders and fine agglomeration.
Whatever the application, the low quantity of product in the Turbulizer and short residence time provide efficient use of installed power.
