Drying
Oven - An Industrial Workhorse
Drying oven
is an industrial wonder. It is used to dry webs, nonwovens, fabrics,
printed circuit boards, wires, papers after printing and several
other products. The hot air drying oven includes dryers with fume
oxidizers, through-air dryers and floatation dryers.
Benefits
of Drying Oven
The drying ovens have several benefits, which are as follows:
• The drying oven leads to uniform heating of webs, wires,
fabrics, circuit boards and other products.
• Rapid product heating increases line speeds.
• There are automatic feedback temperature control systems.
• Products are protected on emergency line stops.
Types
of Drying Oven
Drying oven has the following types with multifarious functions
that serve all types of industrial purposes.
Floatation
Dryers - these dryers produce heated air from both above
and below the product, which imparts uniform heating to the product.
This accelerates the drying process to a large extent. The drying
also supports the web, which floats between the air nozzles without
making any direct contact. This web is ideal for those products,
which has coating on both sides.
Dryers
with Fume Oxidizers - these are appropriate for products
like drying solvent-based coatings, adhesives, inks, finishes
and saturants. The dryers dry the coating as well as capture and
destroy the evaporated VOCs. The VOCs actually serve as fuel for
the dryers.
Through
Air Dryers - these dryers remove moisture from the air-permeable
products by emitting heated air through the product. This provides
high heat transfer rates and makes the through-air method appropriate
for drying products like nonwovens, fabrics and fibres.
Drying
Oven - Precautions
You must be cautious while you are using a drying oven. It is
an industrially hot oven and has quite a number of hazards. Following
are the precautions you must follow:
• Start the oven early in the day so that you can be sure
of the temperature while you are leaving it for the night.
• If the oven has elements in the bottom of the oven drying
area then make sure that the items during drying do not fall of
from the shelves directly onto the elements.
• Check the thermostat regularly to ensure that it has an
accurate calibration.
• If there are number of samples to be dried, then begin
early in the week so that nothing is left unattended during the
weekend.
The drying
oven is a very useful oven for the industries. But you must be
careful and prevent all hazards. Regularly ensure that the equipments
are properly maintained, so that when any fault occurs, you can
easily repair it.
