Material Handling-Drying and Dehumidifying 

There are many categories of material handling, one of them is Drying and Dehumidifying process. 
Polymers of all kinds can be classified into one of two groups: hygroscopic or non-hygroscopic. Hygroscopic materials such as nylon, ABS, PC, and polyesters—to name just a few—will attract and absorb water molecules into the plastic’s interior structure.

Non-hygroscopic plastics such as polyolefins (polyethylene and polypropylene), on the other hand, will not absorb water molecules into the polymer structure. Because hygroscopic polymers attract and absorb water molecules from the atmosphere, they must be dried prior to processing to achieve consistent production results regardless of changes in the ambient temperature and humidity conditions that occur throughout the year.

As the leader of industrial dehumidifier manufacturers, Flying Tiger provides many different types of dehumidifying dryers. 
We can categorize the industrial dehumidifier into 3 large sections; Two Tower Dehumidifying Dryer, Honeycomb Dehumidifying Dryer. and the Vacuum Dehumidifying Dryer. 

Types of Industrial dehumidifier 

Two Tower Dehumidifying Dryer - Consider the “gold standard” of drying hygroscopic resins, the desiccant dryers first emerged in the late 1950s.
This model is the first dehumidifying dryer that Flying Tiger launched in early years. The two tower dehumidifying dryer can provide dehumidifying air below -40 dew point with long periods of machine life time. However the desiccant would need to be replaced with certain working life time, for providing low dew point dehumidifying air.

Honeycomb Dehumidifying Dryer - Honeycomb Dehumidifying Dryer provides continuous closed-loop drying. Different sections of the rotating desiccant wheel are exposed to process air, regeneration, or cooling. The in-process portion of the wheel is said to absorb moisture at a more constant rate than a standard desiccant bed, eliminating dewpoint and temperature spikes, which were problems with older desiccant-bed designs, though suppliers say they have been minimized or eliminated with newer ones. Desiccant-wheel technology reportedly also requires less maintenance and eliminates contamination problems associated with desiccant beds.

Vacuum Dehumidifying Dryer - Instead of blowing hot, dry air over the pellets to draw out the moisture, the newest type of dryer on the market uses vacuum to reduce the boiling point of water, literally pulling the water vapor from the resin pellets. Makers of these units boast of using only 20% as much energy and 17% as much drying time as other dryers. They also permit much lower drying temperatures—e.g., 300 F for PET vs. the usual 350 F. Vacuum dryers can reportedly dry most hygroscopic resins.
Vacuum drying reportedly uses 70% to 80% less energy than desiccant drying because it eliminates regeneration heating and cooling.

Which industrial dehumidifier matches your requirement?

Flying Tiger as a professional auxiliary equipment manufacturer ( industrial dehumidifier manufacturer), we have all three types of dehumidifying dryers for different demands and requirements of dehumidifying and drying processes. We are able to customize different dew point requirements for individual customers. The standard dew point is -40, after customizing Flying Tiger is able to provide -60,-70, and -80 dew point dehumidifying dryers. For different application please contact us directly for further discussion.
