Ovens for Many Applications

Company offers broad range of industrial ovens, including continuous models custom-designed for the specific application. The gas-fired drive-shaft tempering oven shown achieved a uniformity of +/-2 oF at 450oF (232oC). The parts were conveyed through the oven on a custom-designed part holder riding on a two-chain conveyor. Other heat-processing equipment can be used for metal finishing, preheating, solder reflow, composite curing, drying, aging, sterilizing and shrink-fitting. Equipment can be heated by gas (direct and indirect), electric and steam with temperature ratings to 1,400 oF (760oC).

Infrared Oven

BT Series uses a refractory board reflector that can withstand a much higher temperature than a metallic reflector. The unit requires no air or water cooling and is designed to operate continuously in a high temperature environment. Because cooling is not required, airflow does not contaminating 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 system to augment an existing process. Because of its design, it also can be mounted inside a convection oven.

3-Zone Heater

Black Flash BF3-4500S puts heat just where you need it -- over a pocket, at the bottom of a garment, or over an entire imprinted area. With this design, you save on energy, reduce heat on your platens, and produce a cooler work area. The three-zone heater can be positioned into the aluminum frames for convenient application with an automatic printer.

Infrared Curing Tower

High intensity infrared tower uses short-wave infrared heaters and a drive system to cure silicone tubing at adjustable rates. A driven capstan wheel pulls the extrusion from the die up through the heaters. The intense (91.2 kW), focused, infrared heat ensures that the tubing reaches green strength quickly, which maintains the desired diameter and wall thickness of the extrusion. Process controls are mounted in a NEMA 12 enclosure on the tower. Product heating is controlled by a closed-loop feedback system using an optical pyrometer for noncontact product temperature measurement and SCR power controllers to regulate power to the heaters.

Airless Dryer

Developed and tested by Keith Engineering Ltd., Sydney, Australia, the Keith airless dryer uses superheated steam at atmospheric pressure as the drying medium. It is noted for reducing air pollution and process odors, and 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 greatly reduced and oxidation-sensitive products are not placed at risk.

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 readily absorbed 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 the vapor from the heater area.

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 750oF (399oC).
