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.

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.

Model SCFIII ultra-sanitary machine has fully welded/watertight panels and sloped drainage floors.

Claiming that a dryer can dry or dehydrate almost any solid may seem like a bold and sweeping statement. Yet, it is true.

A conveyor dryer will be used to anneal and stress relieve brass castings by an ammunition manufacturer.

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.

Macrowave employs volumetric heating that keeps the temperature uniform throughout temperature-sensitive materials. 

When planning a new industrial process or updating an existing one, a number of different drying technologies can be used.
