The beginning of a movie or book sets the tone for the whole story. In a similar way, this also is true for continuous flow process dryers. Though instead of the first few pages or opening scenes, a process dryer starts with the introduction of the product to the dryer’s conveyor.
In this issue of Process Heating, we look at how to evaluate your thermal processing equipment from specification to sundowning to extend its useful life.
The 2.5 and 3” line vacuum conveyors convert hose, tube or pipe into an inline conveying system for materials up to 900°F (482°C). The air-operated conveyors are available with smooth ends to fit into hose or tube and be secured with a hose clamp.
Gathering key information about your process and application, and sharing it with prospective dryer manufacturers before they quote your job, will help ensure you get a well-designed system.
Regular readers of Process Heating understand that each of the myriad dryer designs can effectively remove moisture from a range of materials. But, each type of dryer also comes with capabilities and characteristics that offer either advantages or disadvantages based on the materials to be processed and requirements of each application.
Continuous drying systems can effectively dry or dehydrate many products in the process markets. When considering continuous-conveyor vs. fluid-bed or rotary industrial dryers, keep these points in mind.
Designed with single-, split- and dual-direction belts, Thermatrol electric, gas or propane conveyor ovens utilize infrared heaters, infra-air or combination infrared/convection heating so specific process needs are met.
Some drying technologies are better suited for certain industrial applications than others. Learn where drying processes and fluid-bed, rotary drum, rolling-bed and belt dryer technologies intersect best.
