5-3.Efficient method of Infrared ray drying

5-3-1.Distance from the Heater

5-3-1.Distance from the Heater

The infrared rays are projected from the heater to reach the heating object is propagated through space.
Because the space is not being vacuum exists air, infrared rays will be to heat the air.
And, correspondingly, the amount of heat that reaches the object to be heated is attenuated.

Distance of the object to be heated and the heater is advantageous closer.

5-3-2.Removal of water vapor

Supposing the air is gas of 80% of nitrogen, and 20% of oxygen in simple, the content of vapor will increase by drying work.
Infrared rays projected from the heater is absorbed by the vapor.
And, correspondingly, the amount of heat that reaches the object to be heated is attenuated.

Infrared rays projection are advantageous in dry air.

5-3-3.Projection angle

About many material, if the degree of angle of projection exceeds 60 degrees, an absorptivity will worsen quickly.

5-3-3.Projection angle

* Oriented emissivity varies with temperature.

5-3-4.Reuse of reflected infrared rays

Infrared rays projected from the heater are reflected to reach the heating object.

(1)The reflected infrared rays will be diffused into the space, but are reused large incident light intensity in reflection mirror the more positive reflection by a right angle projection.

5-3-4.Reuse of reflected infrared rays

(2)Diffuse reflection of infrared rays will be dissipated into the space, but it is reused by large enough reflector mirror.

5-3-5.Removal of volatile matters

When the volatiles of heating object is attached to the reflector mirror of the heater, which is dropped the reflection efficiency of the heater.
And, correspondingly, the amount of heat that reaches the object to be heated is attenuated.
Such as to generate volatile matters, that is need the horizontal heating and avoid the vertical heating.
