Specifications
Soxi is one of the top plastic material dryer manufacturers , our plastic dryer machine will avoid the following questions. In the plastic machinery equipment, 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 plastics dryer machine . 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 drying machines 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
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.
Why Using Dehumidification Resin Dryer Machine?
The coastal areas of China belong to maritime climate and the annual relative humidity is over 75%RH, easy to cause the excessive moisture of resin particles. As the moisture and hygroscopicity of
the resin particles are different from those of the previous production process, the particles tend to generate many problems such as bubbles, silver streaks, poor transparency, cracks,
insufficient durability, flowing marks, poor stability in size control, etc. during the molding. (according to the research report issued by state plastic institute SPI, the moisture of molding
plastic particles should be reduced to 0.02%) most of the plastic raw materials are hygroscopic.
So when they are taken out of the package and exposed to the air, they begin to absorb moisture. In the case of the maritime climate, the regular hot-air hopper dryer will take moisture in the air
to materials, so it can not prevent materials from absorbing moisture. Using Soxi resin dryer machine can solve these problems.
Plastic Drying Machine Molecule Sieve
Molecule sieve is a type of alkali metal aluminum silicate. It is with the crystal structure and characteristics. Its surface is a solid matrix with many inner equal aperture holes that are
arranged in good order, and it is with a very large cavity on the inner surface. The molecule sieve selectively absorbs the molecules according to the size of the crystal inner holes. That’s to
say, it absorbs the molecules at certain sizes and excludes molecules at a larger weight. That is how the name of the molecule sieve comes from.
The absorption area of the molecular sieve can reach up to 600-800㎡/g, if we lay open the multi-stage honeycomb rotary molecule sieve, its surface area can reach up to 14.5 k㎡, which equals the
size of 1848 standard football fields.
The new type of multi-stage honeycomb dehumidifying drier takes use of the large area rotary wheel containing a fixed absorbent or absorption material for air dehumidification. It can provide the
dried air at dew point below -40℃--70℃. The excellent airproof condition and circular operation of the rotary wheel ensure the final moisture content of plastic is lower than 0.02%. the various
types of machines with the air volume ranging 60-2000m³/h can meet different demands on drying capacity.
As one of plastic machine manufacturers, we will do our best to meet all the needs of customers.
