The vacuum hot air circulation drying equipment increases the
saturated vapor pressure of water in the environment where the coil
insulation material is located by vacuuming, making it easier for
it to evaporate from the insulation paper. During this period, it
is continuously heated and the temperature is increased to ensure
the gasification energy of water and make it easier for water to be
discharged.
In modern industrial production, drying is an indispensable and
important link, and vacuum hot air circulation drying equipment is
becoming the preferred choice for more and more enterprises due to
its excellent performance and wide application fields.
1, Principle of Vacuum Hot Air Circulation Drying Equipment
The vacuum hot air circulation drying equipment adopts the
principle of hot air circulation in a vacuum environment, which
lowers the boiling point of water by reducing the air pressure,
allowing the material to quickly evaporate moisture at low
temperatures. The equipment mainly consists of a vacuum system, a
heating system, a circulating fan, a drying chamber, a control
system, etc. During operation, the vacuum pump pumps the drying
chamber to a vacuum state, the heating system provides a heat
source, and the circulating fan circulates hot air in the drying
chamber, uniformly heating the material and removing evaporated
moisture, thereby achieving rapid drying of the material.
2, Advantages of vacuum hot air circulation drying equipment
Efficient drying: In a vacuum environment, the boiling point of
water decreases, the evaporation rate of material moisture
accelerates, the drying time is significantly shortened, and the
production efficiency is significantly improved.
Low temperature drying: In a vacuum environment, materials can be
dried at lower temperatures, effectively avoiding the deterioration
of heat sensitive materials due to high temperatures and
maintaining the active ingredients and quality of the materials.
Uniform drying: The hot air circulation system ensures uniform
temperature in the drying chamber, uniform heating of materials,
consistent drying effect, and avoids local overheating or uneven
drying.
Energy saving and environmental protection: In a vacuum
environment, the specific heat capacity of hot air decreases, the
heat utilization efficiency increases, and energy consumption is
significantly reduced. At the same time, a vacuum environment can
effectively prevent material oxidation and pollution, reduce
exhaust emissions, and be more environmentally friendly.
Easy to operate: The equipment adopts an automated control system,
which is simple and convenient to operate. Drying parameters can be
set according to different materials to achieve intelligent
control.
