Yushine Desiccant Wheel Dryer: High-End Plastic Resin Drying

Yushine Desiccant Wheel Dryer is a high-end product for plastic resin drying. Our experienced team can provide the ultimate quality desiccant dryer machines. We have a honeycomb dehumidifier, a two-in-one honeycomb dehumidifying dryer, and a three-in-one compact honeycomb dehumidifying dryer.

  • The desiccant dryer’s hopper preserves heat using a pipe design with a down blow, which causes air to collate and form a cyclone. This prevents heat from being lost and improves efficiency.
  • Allows three functions of dehumidification, regeneration, and cooling to occur at a similar time.
  • It is highly efficient and consumes less energy.
  • The design is compact, which saves floor space.
  • Maintain the dew point at a constant level. Easy to use and have simple maintenance
  • Optimum performance in drying plastic resin
Advanced Dehumidification with Superior Performance

Advanced Dehumidification with Superior Performance

Yushine desiccant dryers, also called dehumidifying dryers, are honeycomb desiccant dryers with a more advanced design and advantages than the standard twin-tower desiccant dryers. Instead of conventional desiccant beds, they use a rotating honeycomb-structured desiccant wheel. This wheel comprises several sections or segments that enable simultaneous cooling, regeneration, and drying.

Our honeycomb desiccant dryer delivers unmatched performance; dew point as low as -40°C (the lowest), up to 35% energy savings compared to traditional dryers, and drying temperatures up to 320°F (160°C) for different materials. Customizable hopper sizes and configurations allow us to meet your specific needs flexibly.

 

SCD Honeycomb All-in-One Dryer: Comprehensive Solution for Plastic Resin Drying

A single set of SCD compact drying machines integrates the processes of dehumidification, drying, and dual-stage conveying, which is used for drying engineering plastics like PET, PC, TPU, and PBT with dew-point below -40°C. A honeycomb rotor guarantees stable dry air with a low dew point; meanwhile, down-blowing double stainless steel drying hoppers ensure even drying and minimum heat loss.

The closed-loop device stops contamination and moisture reabsorption, while the advanced feeding system furnished with an off valve prevents surplus raw materials from going into hopper pipes. If required, there is also a PLC touchscreen controller for centralized automatic control and an optional dew point detection instrument to achieve accurate monitoring.

The three-in-one dehumidifying dryer SCD series is perfect for various applications in the plastic industry because it offers a complete solution to your drying needs more efficiently. For more information, don’t hesitate to get in touch with us!

What’s the difference between hygroscopic and non-hygroscopic plastics?

Hygroscopic plastics implies those materials which soak up moisture within their molecular structure e.g. nylon, TPU, ABS, and PET while non-hygroscopic polymers refer to those that do not absorb water into the polymer itself but can let it be at its surface. Examples of the latter include PVC, polypropylene, polystyrene among others.

Why should hygroscopic polymers be dried?

Drying is essential for any resin that absorbs water from the atmosphere because this may affect its quality and consistency during processing – cloudy or streaked appearance in transparent products are some signs; moreover, such plastics could become weak or exhibit poor performance properties.

What methods can you use to dry plastic resins?

Hot air dryers and desiccant dryers are the two common options for drying plastic resins. The former applies convection heating of air which then dries these resins while the latter employs a hygroscopic material (desiccant) that adsorbs and holds water thus achieving continuous air-drying cycle necessary for drying hygroscopic materials.

How does a hot air dryer work?

A hot air dryer functions by pulling ambient air through a filter; it is heated up before being passed over plastic resins in a drying hopper; finally this warm moistless (dry)air may either vented outside or recycled back to save energy . They can also be used to preheat plastics so as to improve energy efficiency and productivity gains.

How does a desiccant dryer function, and what is the working principle?

Desiccant dryers (also called adsorption dryers ) direct wet vapor-laden airstreams across beds packed with moisture-absorbing granules like silica gel beads. In most cases, these systems have twin towers, so one tower regenerates while another dries, thereby ensuring continuous operation for long periods at low dew points.
There are multiple types of desiccant dryers on the market—the working principle of everyone alike. The main difference among other plastic dryers or desiccant dryers is that they use hot, dry air compared to ambient air to eliminate the moisture content from plastic resin. The system works in a closed loop. It does not allow air to escape from the system and mix with ambient air. Instead, the desiccant dryer circulates air through a plastic resin to make it completely dry.
The working principle of the desiccant dryer is as follows:
> At first, the air through the hopper moves to the dryer and later to the heat-exchanging device to cool.
>Next, the distributor causes the air to go through the desiccant chamber.
>Now, the desiccant plays its part and takes up all the moisture air contains, thus making it dry.
> This dry air then moves towards the blower, and from the blower, it gets distributed from the pipe located at the
bottom of the desiccant dryer hopper.
>When the moisture content within a desiccant exceeds a certain level, you need to regenerate the desiccant
> The dew point meter periodically measures the moisture content and displays it in real-time.To use desiccant again, you need to remove the moisture content through desiccant through a process known regeneration. You can do this by using hot air or compressed dried air. it is essential to keep your desiccant dryer operational.
》In regeneration, the heater raises the air temperature and makes it hot>This hot air then, with the help of a blower, is forced through the desiccant
> The air absorbs the excess moisture content from the desiccant and exists in ambient air
>To cool the hot desiccant, ambient air is utilized before employing it in the process of drying>The honeycomb wheel rotor keeps rotating throughout the process periodically to switch containers

 

How does the desiccant dryer work with conveying?

Desiccant dryers with conveying are also known as 3-in-1 desiccant dryers. They have a compact design and save space because of the transferring feature. They are movable because they come with wheels in the foundation.
The desiccant dryer can perform three functions: drying, dehumidifying, and two-step conveying.
They provide a downflow of air in cyclone form, which prevents heat loss and increases the desiccant dryer’s efficiency. The desiccant dryer with a conveying feature has two structures, including an airtight structure and a semi-open structure; you can choose either depending on your needs.
You can process highly hygroscopic materials, including PA, PBT, PC, or PET. It can maintain a low dew point and comes with a microprocessor for better control over operational parameters, including humidity and dew point temperature.
