About Industrial Dryers
Industrial dryers are used to remove liquids or moisture
from bulk solids, powders, parts and sometimes other liquids by evaporation
and sublimation processes. The particular industrial drying technologies
can vary greatly, depending on the type of industrial dryer needed for
the industrial drying process. Often, industrial dryers work very much
like home clothes drying units, by using either industrial gas dryers
or industrial electric dryers to heat the air that dries the clothing.
Other types of fuels are also used in large industrial dryers, such as
wood or coal to heat the rotary drums that dry grain and other wet processed
crops. Compressed air dryers and infrared
heat dryers are additional
types used in the bulk drying of materials. The use of infrared heat
is unique from other industrial dryers in that it is most commonly used
for the curing of wet coatings or inks in processes such as silk screening.
The most important thing for many industrial dryer manufacturers is to
remember the amount of exposure to heat for a period of time. In the
case of flash dryers, the process is extreme but fast, in that the material
is exposed for a very short amount of time but given enough heat to be
dried almost instantaneously. In some processes, materials can be dried
without the use of heat or even cool air. These types of industrial dryers
use a process called desiccation, which uses tiny moisture-drawing granules
to absorb moisture in a way that is similar to how cat litter reacts
with fluid. Many drying units are custom made for maximum efficiency
and profitability.
The use of conveyer
systems by industrial dryer manufacturers is very
common. Conveyor
belts carry the desired material through the different
stages of the drying process in order to dry products in an easy and
efficient way. Using conveyor systems to dry materials is especially
useful for food and agricultural industries. Contamination is a minimal
concern because most industrial drying systems are very sanitary. Industrial
dryers are, and should be, cleaned often, in between each drying procedure.
There are two types of industrial dryers: industrial dryers that come
into direct contact with heat (direct industrial dryers) and industrial
dryers that do not (indirect industrial dryers). Each of these industrial
dryers have different types of industrial dryers used for different applications.
Industrial dryer manufacturers design products to be used in a variety
of industries, such as the food processing, pharmaceutical, paper, pollution
control and agricultural sectors. Diverse materials need to be dried
in completely different businesses, such as chemicals for research and
medical concerns, paper for printing and packaging operations and edible
materials for further processing into popular foods and snacks. Industrial
dryers have important uses all over the world.

Types of Industrial Dryers
- are
the most common types of industrial dryers. The product to be dried
comes into direct contact with heated air dispensed by the machine.
-
use a belt to move materials through the dryer at a continuous feed.
Agricultural products are often dried on a belt or similar conveyer
dryer system.
-
remove water and other contaminants from compressed air and the lines
that carry it. This is done via refrigerant or desiccant processes.
-
remove water and moisture from a product with absorption, by way of
grainy materials such as silica gel or activated alumina.
-
are industrial dryers that dry a substance or material during exposure
to a short burst of high heat. Water sludge is often dried this
way at water treatment plants for the easy removal of contaminants.
-
are used to dry heat sensitive materials such as chemicals and pharmaceuticals
in small batches.
- use
gas to heat and dry a product as desired. These dryers are quite common.
-
are used most often for the curing of water-based inks and coatings
found in the painting and the screenprinting industries. These use
infrared radiation to quickly dry or set the material.
-
can be gas, liquid or solid fuel fired, and pass material through a
heated rotating drum. Sometimes the drums have multiple chambers
that allow a longer pass to get through the drum.
-
take a material, such as wet sludge or wet powder, and spin it centrifugally,
then direct a line of spray of the material into a drying chamber,
which rapidly dries the material. This type of dryer is also called
a dispersion dryer.
-
are used during a certain method of pollution control. They take air
polluted with small particles or combustible solids and liquids
and oxidize the organic parts before destroying them.
- are used
to provide low temperature drying of materials in the chemical and
pharmaceutical industries.
