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.
