CIRCULAR TRAY DRYER

Model K-10 Turbo-Dryer is used to remove the bound water of hydration from a specialty chemical at a rate of approximately 100 lb/hr. The dryer yields uniform product due to its positive retention time and close temperature control. Gentle handling allows continuous drying of low-density product without requiring a dust collector. Drying system includes a small fresh-air fan, electric heaters, interconnecting ductwork and temperature controls. Total motor horsepower required for the system is approximately 3 hp, and the required floor space for the primarily vertical system is approximately 5 x 10'.

OVENS AND DRYERS

Thermatrol 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.

INFRARED OVEN

BT 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.

VERTICAL TOWER OVEN FOR DRYING/CURING

Drying 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.

AIRLESS DRYER

Airless Dryer, developed and tested in New Zealand by Keith Engineering Ltd. of Sydney, Australia, uses superheated steam at atmospheric pressure as the drying medium. The drying system reduces air pollution and process odors while providing high product quality. The airless dryer does not require odor control equipment. Moisture from the product is condensed and noncondensables are ducted to the burners. Because superheated steam is used for drying, the risk of fire is reduced and the quality of oxidation-sensitive products is preserved.

THROUGH-AIR DRYER HEATS AIR-PERMEABLE PRODUCTS

Through-air drying technology can be used to heat air-permeable products such as nonwovens. Heated air is supplied to the interior of the dryer enclosure through a perforated plenum mounted above the product line. A suction plenum beneath the line mechanically pulls hot air through the product. Heat transfer is almost instant and throughout the thickness of the product. Air drawn in through the suction plenum is returned to the burner chamber for reheating and reuse. For products that are heated in an indexing operation, an air-bypass system can be used to keep the dryer at operating temperature, cutting recovery time and energy costs.

IMPINGEMENT FLUIDIZED BED DRYERS AND TOASTERS

AeroFlow fluid-bed system uses high velocity air-jets from nozzles above the conveyor to impinge air through the product bed and onto a nonperforated conveyor. This creates a gentle tumbling action as the product bed is fluidized and dried. The air-to-product fluidization throughout the product bed results in good heat transfer and helps
produce the desired product texture, color and flavor development. Product is conveyed through the dryer or toaster using a natural frequency designed vibrating pan conveyor.

CONTINUOUS DRYING PROCESS REACHES LOW MOISTURE LEVELS

Drying to moistures of 0.5 to 0.1 percent or lower requires uniform heating and residence time. Paddle dryer allows you to reach these objectives with an indirectly heated continuous process. The mixing action of the paddle dryer's dual intermeshing agitators with heated wedge-shaped paddles provides for uniform heat transfer. Because the product moves through the dryer by displacement, residence time is controlled by the feed rate. Heating can be achieved with steam or thermal fluid at temperatures up to 750 degrees F (399 degrees C).
