Air Blow Heater

The heat which appears in the temperature of a substance and can be observed is sensible heat. The heat unobservable although the state of a substance is changed is latent heat. Sensible heat + Latent heat = Total heat The ...

If alcoholic disinfection is carried out before injecting, when alcohol evaporates, he will have a cold feeling to because heat is taken. In order for a liquid to turn into gas, energy is required and this energy is called evaporation ...

2-7-1.Spirits of Dry and Wet Líu Ān (Chinese: 劉安, c.179 – 122 BC) was a Chinese king and advisor to his nephew, Emperor Wu of Han (武帝). The old days of more than 2000 years from now, Concept of humidity ...

We have explained the relative humidity and absolute humidity to 2-5 from 2-1. Let’s check again here. Quantity the water of which exists in the air with absolute humidity Even if it heats air, since the weight of the water ...

Absolute humidity Generally, if it is only called “Humidity”, “Relative Humidity =RH” will be pointed out, but it is convenient to use the absolute humidity from which a value does not change in a design or control of a drier ...

Relative humidity RH Relative humidity is the ratio of the partial pressure of water vapor in an air-water mixture to the saturated vapor pressure of water at a prescribed temperature. The relative humidity of air depends on temperature and the ...

This video is a demonstration that is heating to 1000 ℃ the air  by the Air Blow Heater.

The saturation water vapor amount is the representation of g in the mass of water vapor that can be present in the space of 1m3. Absolute humidity volume, saturation water vapor density is also known as, aka. Saturation water vapor ...

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 ...

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 ...

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 ...

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 ...

This video is the heating demonstration of Ignition of wood pellets by the Air Blow Heater.

This video is the heating demonstration of Holing and Cutting in polystyrene foam by the Air Blow heater.

This video is the heating demonstration of Holing High Density Polyethylene－HDPE bottle by the Air Blow Heater.

[ Problem Point ] Could not be heated the dummy gas to evaluate the performance of the catalyst. [ ⇒Kaizen Point ] The double glazing tube specification DGH type for medicine-proof of the Air Blow Heater was used, and it ...

[ Problem Point ] There was no non-contact heater that can be accurately temperature control. [ ⇒Kaizen Point ] We were heated in the Air Blow Heater. In the hot air that was temperature-controlled exactly, we were able to be ...
