There is a limit to the amount of water vapor that air can contain. Within the air, water movement may become gas (vapor) from a liquid, that or become liquid from gas (vapor) has been constantly repeated. The temperature that ...

(Q) Can heat in the far-infrared rays metal? (A) Since there is a lot of metal electrons, it reflects the electromagnetic waves (far-infrared rays) in general. The good conductivity metal such as gold and aluminum, it is hard to heating ...

(1) Infrared Rays are subdivided into several scheme. ISO 20473 specifies the following scheme: Designation Abbreviation Wavelength Near-Infrared NIR 0.78–3 µm Mid-Infrared MIR 3–50 µm Far-Infrared FIR 50–1000 µm (2) Difference in frequency = The difference between the heating capacity By “Wien’s displacement ...

The method of heating the ceramic to make a far-infrared artificially is common. The fine ceramics of an alumina system or a zirconium system are used well. Wavelength and the emittance change by a kind and the heating temperature of ...

The Chapter 1 focused on moisture inside material. The Chapter 2 focuses on the moisture emitted in the form of vapor into the air. Definition of the humidity Of humidity, it is a representation of a number the wetness in ...

  【 Infrared Absorption Rate 】 Please confirm the index of absorption of infrared rays in this table. The material absorbed by about 0.5 = 50% or more is suitable for the infrared heating.

1.Planck Radiation Law Max Karl Ernst Ludwig Planck, FRS (23 April 1858 – 4 October 1947) Planck’s law describes the electromagnetic radiation emitted by a black body in thermal equilibrium at a definite temperature. The law is named after Max ...

The thermal energy transfer from higher temperature to lower temperature. Transfer of the thermal energy , there are three principles, Conduction, Convection, and Radiation. In an actual situation, transfer of the thermal energy is performed in the form these three ...

Infrared Rays are subdivided into several scheme. ISO 20473 specifies the following scheme: Designation Abbreviation Wavelength Near-Infrared NIR 0.78–3 µm Mid-Infrared MIR 3–50 µm Far-Infrared FIR 50–1000 µm The International Commission on Illumination (CIE) recommended the division of infrared radiation into the following ...

Constant drying period is the mass of the water which evaporates per unit time and unit surface area. The unit is kg/s㎡. Constant drying rate Jc is expressed by the following equation. kH: Mass transfer coefficient Hw: Saturated absolute humidity ...

Although it is not visible, because the light with the power which warms a thing existed “outside red”, it was named “infrared rays.” Infrared rays are the same “Electromagnetic waves” as “X-rays”, “Ultraviolet rays”, “Visible light”, “Microwave”, “Radiofrequency wave”, etc. ...

<Science of the Infrared rays -INDEX- > 1. The discovery of the infrared rays 2. About infrared rays 3. Type of the infrared rays 4. About heating 5. 4 basic laws about radiation 6. Absorption rate of infrared rays 7. ...

Inside moisture material, movement of water (liquid) mainly takes place from the point that moisture content is high to a low point on the surface from an inside in accordance with a slope.  There is capillary suction force action, osmotic ...

The drying speed is taken along a vertical axis, average moisture content is taken along a horizontal axis and the above figure is described, it will become a dry characteristic curve. The drying speed is quantity of water evaporating in a ...

In general, the moisture content of the material is different in the center and the surface of the material. So, it called the Local moisture content, which is the moisture content of any measurement point. And, it called the Average ...

The point which shifts to the Decreasing drying period from the Constant drying period is called the Critical moisture content Wc. The moisture content in which dryness does not advance any more is called the Equilibrium moisture content We. In ...

As shown in the figure above, wet material is made up the solid , the liquid and the gas as a gap. The weight of material is the sum total of the liquid and the solid. Since the solid weight ...

As shown in the figure above, wet material is made up the solid , the liquid and the gas as a gap. Gas Mass : Mg Liquid Mass : Ml Solid Mass : Ms Gas volume : Vg Liquid volume ...

Ⅰ.Preheat piriod The material change from initial state to the state that fitted the dry condition. Ⅱ.Constant drying period The surface and the central temperature of materials are kept by the equivalence, and the period which water content decreases linearly ...

The drying is the process of giving heat and a wind to the moist material containing liquids, a small amount of water and a solvent, evaporating a liquid, removing, and drying a product. As a typical example, in the process ...

More quickly, More uniformly, demanded from the dry process in the manufacture. In order to realize it, it is important to know how heat and a substance will move in the from internal to surface for dryness. In addition, it ...
