Industrial drying is an important process. There are many different contexts in which access to industrial drying equipment is necessary. There is a particularly large need within industry for drying equipment that can be used to dry large quantities of free flowing materials. Such materials include fibers, agricultural products, industrial chemicals and a wide variety of other materials.
Flash dryers can be thought of as cousins of pneumatic conveyors and rotary dryers. They are like pneumatic conveyors in that they use pressurized streams of gas to move free flowing materials through a conveyance tube, and they are like rotary dryers in that they use that gas, once it is heated, to remove moisture from the materials suspended in the conveyance tube. The principle of drying in a flash dryer is exactly the same as that of a rotary dryer. The materials within the tube are agitated and exposed to the hot air within the tube, which causes them to become dry. The pressurized stream of gas is also used to move the product from one place to another, which means that product to be dried can be fed continuously into one end and retrieved for the next phase in the product’s development in the other end.
Industrial flash dryers often must also be equipped with secondary equipment that makes the process more efficient and less likely to degrade the environment. For example, many flash dryers are equipped with air scrubbing utilities that prevent contaminated air from the drying process from being expelled into the environment. Also, some flash dryers also feature rotary utilities that help to provide additional agitation of materials, which exposes a greater amount of product to the heated gasses, which dries materials more quickly and thoroughly. Flash dryers are very effective drying utilities, and for this reason they are very popular in many industrial contexts.
