Soxi is one of the top plastic material dryer manufacturers, our plastic drying machine will avoid the following questions. In the plastic auxiliary machinery, the plastic in the resin state easily absorbs moisture from the air. In another word, the moisture absorbed during storage and before processing will seriously lower the quality of final molded products,e.g. nylon, ABS, polycarbonate, etc. Even if the non-bibulous plastic, is sensitive to moisture pollution(moisture accumulates at the surface of plastic granules), therefore, proper plastic dryer dehumidifying treatment before processing for plastic is required to ensure the best molding effect of the product. Before moulding, plastic must be dried by injection molding dryer to the moisture content of below 0.02%. Many problems will be caused by improper dryings, such as bubble, flow mark, hydrolysis, product crazing, poor impact, silver thread, galling, unstable size, and poor viscidity.

Types Of Plastic Dryer

SOXI plastic dryers are built to solve those problems. The plastic drying machine adopts a multi-section honeycomb wheel and stainless steel double-layer down blowing thermal insulation hopper, which integrates three dehumidifying, drying, and feeding machines, and has the advantages of fast, simple, compact, and durable material supply with the widespread use of engineering plastics, Dehumidifying dryer has gradually replaced the traditional hot air dryer.

Product in this category includes a Three-in-one dehumidification dryer, honeycomb dehumidifier,three-in-one honeycomb dehumidifier, optical small-scale desiccant dryer, Europeanization double-layer dryer,two-in-one loading and drying machine, hot air hopper dryer. The three-in-one dehumidifying dryer is a new product developed according to the actual situation of the plastic industry.

Plastic Drying Machine Dew Point Temperature

Plastic Drying Machine Dew Point Temperature

The dew point is the temperature at which air is saturated with water vapor, which is the gaseous state of water.

When the air has reached the dew-point temperature at a particular pressure, the water vapor in the air is in equilibrium with liquid water, meaning water vapor is condensing at the same rate at which liquid water is evaporating. Below the dew point, liquid water will begin to condense on solid surfaces (such as blades of grass) or around solid particles in the atmosphere (such as dust or salt), forming clouds or fog.

Dew point is closely linked to relative humidity, which is the ratio of the pressure of water vapor in a parcel of air relative to the saturation pressure of water vapor in that same parcel of air at a specific temperature. Relative humidity (RH) is expressed as a percentage. The relative humidity is 100 percent when the dew point and the temperature are the same. If the temperature drops any further, condensation will result, and liquid water will begin to form. Compared to relative humidity, the dew point is frequently cited as a more accurate way of measuring the humidity and comfort of the air, since it is an absolute measurement (unlike relative humidity). Most people are comfortable with a dew-point temperature of 60 degrees Fahrenheit (16 degrees Celsius) or lower. At a higher dew point of, for example, 70 F (21 C), most people feel hot or "sticky" because the amount of water vapor in the air slows the evaporation of perspiration and keeps the body from cooling.

The dew–point temperature ordinary dehumidification dryer can reach is -30℃, as the dew-point temperature of dehumidification dryer is all minus value, it means the dew-point temperature is very low.
