For fine layer coating of individual particles, the intensive, continuous mixing action of the Hosokawa Turbulizer makes it probably one of the most successful units on the market. If your requirement is for efficient dispersion of a small quantity of material into a larger bulk for thin layer coating of individual particles then the Turbulizer is ideal. The high efficiency mixer is proven in coating applications for taste masking, improved flow characteristics, the protection of core particles or controlled release effect or controlled dissolving time.
For example 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 powdery melt. The base product, as well as the powdery 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 320°C are achieved with hot oil for this application although steam at 16bar(g) can also be used. Product residence time is only 5 seconds (approx) during which the base product is coated with the melt. Product discharge temperatures are typically 65°C for this type of application.
The Hosokawa Turbulizer offers effective fine layer coating and dispersing of liquids on solids on a wide range of products as well as heating and cooling of powdery products, continuous reacting of gasses with powders and fine agglomeration.
The Turbulizer is also extremely efficient in solids-solids mixing. The flexibility in operation of this high speed paddle mixer delivers rapid, 1-40 second lump free mixing and low energy usage as only a small amount of product is actually being mixed at any one time.
The unit is available in a range of sizes and executions in the food, chemical, minerals and other industries including the pharmaceutical industry where it’s coating application capabilities are proving valuable.
