The compact design is high efficiency and the dew point could attain -40℃ under ideal conditions. The single unit includes a honeycomb rotor dehumidifier and a down-blowing double-layer stainless steel hopper dryer.

1. Under ideal conditions, it can provide lower than -40℃ dew-point dehumidified air.

2. SCD series has semi-open and hermetic structures.

3. Heat-preserved drying hopper barrel adopts a down blowpipe design and collocates with cyclone air exhaust to avoid heat loss and improve drying efficiency.

3 in 1 Dehumidifying Dryer

The SCD series combines the function of dehumidifying, drying, and two-stage conveying into one unit with semi-open and hermetic structures. This dehumidifying dryer includes a honeycomb rotor dehumidifier and a down-blowing double-layer stainless steel hopper dryer.

2 in 1 dehumidifying dryer

The SDD series 2 in 1 dehumidifying dryer includes dehumidifying and drying in 1 machine, and when under ideal conditions, the dew point could make it to -40℃. This machine is suited for those who need dehumidifying hygroscopic plastic engineering materials. Especially when the drying hopper needs a very big size, over 150kg, and we could make 1000kg about 1 ton.

Honeycomb Dehumidifier

SD-H series adopt the honey-comb rotor to dry hygroscopic engineering plastics effectively.
Yushine dehumidifiers use double cooler construction to make sure lower return air and the dew point, which could reach lower than-40°C under ideal conditions
The largest size of the dehumidifier can provide dry air up to 4000m3/hr. The regenerative temperature could be precisely controlled by the PID temperature controller. LCD and dew point monitors are optional.

Yushine Dehumidifying Dryer applications

  • Food & Beverage Industry

Compressed air is very important to back up the f Food & Beverage industry because the food products processed in the facility must be moisture and contaminant-free besides, Food & beverage manufacturers are highlighted sanitation; thus, filters and compressed air dryers are very necessary. Dryers and filters could effectively prevent the ingredients, products, and packages are getting into humidity and condensation.

  • Electrical and Electronic Applications

  • Medical Apparatus and Instruments Applications

Working Principle

Working Principle
Suction Steps

The hot and humid air returned from the drying material is cooled and blown into the honeycomb rotor. The moisture in the air is adsorbed by the rotor and then desorbed by the regenerated heated air. The two airflows act on the rotor at the same time. Because of the rotation, the moisture in the air is continuously adsorbed and desorbed by the regeneration air and then discharged. So, it forms a stable low dew point air to heat the plastic in a closed cycle.

The material suction is sucked into the drying material barrel from the storage barrel or other material storage container. When the magnetic reed switch of the vacuum hopper detects that there is no material, the material suction material immediately runs continuously, so that a vacuum is generated in the vacuum hopper, and the material in the storage barrel is vacuumed. The raw material is sucked into the vacuum hopper due to the pressure difference of the air. When the suction time is completed, the suction motor stops running, and the raw material will fall into the drying barrel due to its own weight. The dried raw material is pumped from the drying barrel to a photoelectric hopper or other hopper mounted on the plastic molding machine.

The closed feeding system circuit can prevent the dried raw materials from being re-damped due to contact with the outside air.
• Intelligent control panel makes sure the performance is stable, simple, and easy to operate with the instructions clear.
• Yushine adopt original brand electric appliances
• Such as original seal Schneider Electric with CE safety label design and Euro standard terminal block.

What Is Dehumidifying Dryer?

The Dehumidifying Dryer is a revolutionary way to extract water from plastic materials and make them extremely dry. The first step in this process, air drying with desiccants before being heated up so they can remove the moisture naturally- without requiring any additional input like electricity or other chemicals – has been proven highly effective at removing almost 100% of excess humidity inside your factory! A simple design that requires no outside assistance will help you save money on costly utility costs while increasing productivity through better quality assurance by eliminating potential problems early on-site rather than waiting until customers complain about bad weather conditions causing delivery delays which could cost many thousands if not millions of worths depending upon.

In this process, when the desiccant bed has reached its moisture-retaining capacity and cannot hold any more water for whatever reason (exhausted), the air is automatically switched to another section of drying equipment. At that point in time, you will need either regenerated or twin tower dryers because they are able to remove all remaining liquids from your product before recycling back into place!

How Does a Dehumidifying Dryer Work?

A dehumidifying dryer is a type of industrial drying equipment that is used to remove moisture from materials through a dehumidification process. This type of dryer works by circulating air over the material to be dried and then passing the air through a dehumidification chamber. The dehumidifying chamber contains a desiccant, which is a substance that absorbs moisture from the air. As the air passes through the chamber, the moisture is absorbed by the desiccant, leaving the air dry. The dehumidified air is then circulated back over the material to be dried, and the process is repeated until the desired level of dryness is achieved. Dehumidifying dryers are often used in applications where it is necessary to remove moisture from materials quickly and efficiently, such as in the food, pharmaceutical, and chemical industries.

Common Applications of the Dehumidifying Dryers
  • Infrared rotating drums IRD – are virtually unlimited and plastics and other industries.
  • Drying of plastic pellets (e. G. PET, ABS/PC, PC, LCP, wood-PP, PP/PE compounds)
  • Crystallization and drying of PET, PPS, PLA (reclaim/pellets)
  • Drying processes with high initial moistures > 1 %
  • Heating of pellets and reclaim before further processing (e. G. PVC, PE) for example to increase the extruder throughput
  • Heating processes for removing residual oligomers and volatile components
  • Drying in the food, feed, and pharmaceutical industries
  • Roasting of coffee beans.
