Product Features of Dehumidification Dryer
- The OCD compact dryers can be equipped with up to four fully insulated drying bins to suit the required total throughput.
- OCD compact dryers are the most effective way of conditioning hygroscopic plastic granules for processing and removing surface moisture.
- The use of corrosion resistant stainless steel ensures a long lifetime and avoids contamination of the plastic granules.
- Transparent window design for filter makes it convenient to monitor the condition of filter.
- Material-contact surface of hopper is specially made of dust-free mirror-like stainless steel, it is suitable for the production of optical lens or food standard plastic products production.
- High-density return air filter ensures no contamination to the material in the conveying of materials.
- For models below OCD-450/300H, air-cooling methods is applied, which ensures low energy-saving and convenient for movement.
ORSTE “Optical” Dehumidifying Dryers provides the advantages of a consistent dew point and maximum energy efficiency. They combine the function of dehumidifying, drying and two-stage conveying into one compact machine, specified for the production of “optical class” and “food standard” products, such as lens, LGP, disposable lunch box etc. The quality desiccant honeycomb rotor provides continuous and constant low dew-point air which can be lower than -40 oC under ideal conditions.

Filter Cleaning
Please periodically clean the dust on the air filters, once per week.
Cleaning steps:
1) Take out the air filter carefully.
2) Blow off the dust on the air filter screen and the cover with pressure air.
3) Wipe off the barrel wall of air filter with dishcloth.
4) After cleaning, place all parts in reversed order carefully.
Note!
Do not let any impurities fall into filter container.
Why Choose OCD-H?
The main reason for the defects of plastic products, such as bubbles, silver lines, flaws, poor transparency, etc. is that plastic raw materials are not completely dried before molding. Hygroscopic plastics, such as TPU, PA, PC, PBT, PET, PETG, PCTG, NYLON and so on, can not be thoroughly dried through traditional methods. It is proved that heated and dehumidified air with low dew-point down to -40oC can make moisture content of such materials lower than 0.02% before molding.
OCD-H honeycomb dehumidifiers, utilizing honeycomb-rotor in a full-closed system to dehumidify process air, can meet such requirements. Hot air with low dew-point produced by this unit is quickly and continuously blowed to plastic particles to completely absorb the moisture, thus to gain a good drying and dehumidifying effect.
