Chemical Refractive window dryer

1、 Principle of chemical spray dryer

Research reports that when a water-based material is placed on the surface of a polyester film, the area where the moisture in the material comes into contact with the polyester film forms a "window" that allows infrared energy to pass through. Thermal energy is simultaneously transmitted to the material through conduction and radiation, and the material is heated while the water evaporates. Due to the effects of evaporation and ventilation cooling, the material temperature rarely exceeds 75 ℃. After the material dries, the "infrared window" will close, and heat can only be transmitted through conduction. As polyester film is a poor conductor of heat, drying the sample can avoid excessive heating.

2、Chemical Refractive window dryer system features：

1) Low energy consumption;

2) For dry liquid materials, there is no need to pre-concentrated or processing of gum for raw materials, etc.;

3) Continuous operation and production

4) Low water consumption;

5) Easy to clean;

6) Simple control and easy operation;

7) Due to the use of flexible drying and high product quality, it can maintain the original color and fragrance;

8) Operations under low temperature and normal pressure conditions, greatly reduces the oxidation of the product;

9) The product has a high loosening dump density, which reduces packaging and transportation costs.

3、Chemical Refractive window dryer Drying conditions：

The factors that restrict dryness on Chemical Refractive window dryer include air inlet temperature, exhaust temperature, air humidity, dry air volume, material liquid treatment, water evaporation, dry room diameter, dry room volume, particle diameter.

When designing the above factors, according to the characteristics of dry materials, the particle size and processing of the required product are determined, especially the diameter and volume of the dry chamber. Because they are indispensable factors, it is not possible to make too many adjustments based on this. Therefore, before the design of the Refractive window dryer, it is very necessary to select appropriate drying conditions on a small test machine.
