Circular Tray DryerTurbo-Dryer can be used to calcine or sinter fine metal oxide powders. Capable of operation at temperatures up to 1,202°F (650°C), the continuous tray dryer includes an internal electrical heating system that helps remove residual moisture. Dry air or nitrogen is used to purge water vapor from the system, keeping fines carryover to a minimum. The proprietary design consists of a stack of rotating circular trays in a sealed enclosure. Material is fed onto the top tray, and after each revolution it is wiped onto the next lower tray. Internal Turbo-Fans circulate heated gas in the enclosure to provide the drying medium.

Drying SystemsLine of drying systems includes Jetzone fluidized bed dryer/puffer/toaster, fluidized bed cooler, impingement cooler, forced convection cooler and belt coolers. Jet-Tube fluidization technique provides fast, uniform and efficient heating, cooling, toasting or puffing of particulate free-flowing products. It is well-suited for dense, difficult-to-cool products. The high-velocity impingement technique provides fast, uniform cooling a wide range of food and non-food industry products. Turbo-Jet forced convection cooler, designed for existing or new post-oven conveyor systems, provides efficient pre-cooling prior to freezing or packaging.

Ovens and DryersThermatrol electric, gas or propane conveyor ovens and dryers utilize infrared heaters, infra-air, or combination infrared/convection heating so specific process needs are met. Other features include inline integral coolers, ability to interface with external PLCs, and integration with robotic operations. The infrared heat panels provide uniform curing and/or drying over the entire process. Recirculating hot air using air knives breaks up moisture barriers and drives solvents from the substrate.
