Infrared Oven with Refractory Board ReflectorBT Series uses a refractory board reflector that can withstand a much higher temperature than a metallic reflector. The unit does not require air or water cooling and is designed to operate continuously in a high temperature environment. Because cooling is not required, airflow does not contaminate the product and the system has a smaller profile. The infrared heater can be used as a stand-alone oven, or it can be designed as a booster to augment an existing process. Because of its design, it also can be mounted inside a convection oven.

Milling Flash DryerWhen a discrete and fine end-product is desired, processors can dry powders, slurries, and filter and centrifuge cakes with a small-footprint milling flash dryer. Units dry and deagglomerate in a single step, allow particle-to-particle collisions to achieve fine products without moving parts, and allow extremely short residence times for temperature-sensitive products. Jet-milling principles preserve particle distribution present in wet feed, and the static classifier minimizes product top size.

Circular Tray DryerTurbo-Dryer can be used to calcine or sinter fine metal oxide powders. Capable of operation at temperatures up to 1,202oF (650oC), 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.

Ovens and DryersThermatrol electric, gas or propane conveyor ovens 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 high-velocity air knives breaks up moisture barriers and drives solvents away from the substrate.

Paddle DryerRosinaire consists of a horizontal, cylindrical vessel containing a longitudinal rotor/paddle assembly. The vessel body is fabricated with external jacket sections through which flows the heat transfer fluid (steam, hot water, hot oil, or chilled water). Radial paddles are fastened to the rotor shaft by means of locknuts. The adjustable paddle orientation determines the residence time of the solids within the vessel. Feed material is either pumped or conveyed into the high-speed, thin-layer, indirect-contact, paddle processor. The centrifugal action of the rotor/paddle assembly delumps and conveys the product material through processor as a thin layer of solids in a helical flowpath along the jacketed wall, resulting in heat transfer coefficients up to 150 BTU/hr/ft2/oF.

Process Gels, Slurries and SolidsSolidaire dryers have high-speed, adjustable paddles that create an agitated, dense, thin layer of material against the jacketed vessel wall. A jet-rotor design allows injection of gas or liquid through the paddles into the thin layer of material flowing along the wall of the unit. Operating modes include indirect, direct and a combination of both. The unit can process a range of heat-sensitive materials, from free-flowing solids to wet cakes and slurries, as well as materials whose flow characteristics change during drying. The dryer also can handle fine, low-density particles that might be fluidized in mechanically or pneumatically agitated equipment.

Vertical Curing SystemUltima system is configurable for continuous, inline curing of components in carriers, strips, magazines, baskets or other transport mediums. The oven design ensures good thermal performance utilizing a small, automated equipment footprint. The vertical format enhances inline integration to any process equipment, or it can be used as a stand-alone system. Process flexibility is achieved via nine separate curing chambers with independent controllers for temperature, airflow and exhaust for effluent gases. Internal active cooling provides reduced process time and product exits at less than 122oF (50oC).

Vertical Tower Oven for Drying/CuringDrying and curing oven incorporates medium-wavelength infrared Type QF heaters. The panel heater delivers radiant heat across the full area of its face. The medium-wavelength energy generated is absorbed readily by water and most products, allowing high drying efficiencies. Hot air is recirculated to enhance drying and save energy. The combination of infrared and air improves drying efficiency by breaking the boundary layer and removing water vapor from the heater area.
