High Capacity Pet Crystallizer Dryer Dehumidifier For Pharmaceutical Industries

High Capacity Plastic PA ABS PC Pet Crystallizer Dehumidifier Dryer

PET crystallizers are used for constant crystallization of un-crystallized PET regrinds or pellets. Processed materials can then be dried and dehumidified directly which can decrease cost. This system mainly consists of heating elements, insulated hopper and agitator screw mixing device. After un-crystallized PET materials are fed into the hopper, the system starts crystallization and agitator starts blending to prevent formation in lumps. Crystallized materials can be conveyed to material storage bin or into drying hopper directly.

Integration of dehumidification, drying and conveying functions;
Dehumidification, drying and conveying integrated unit are equipped with honeycomb rotor for getting low dew-point dry air with good stability. Cut-off valve in semi-open and fully-enclosed feed system are equipped to assure no remnants materials left in material pipe.;
Equipped with micro computer and photosensor hopper for optical machine for micro powder cleaning, avoiding spot in optical products.;
Stainless steel mirror polishing of all material contact surface and closed loop feeding system to avoid the material get contaminate or damp;
High-performance filter to filter dusts down to 0.3um and the filtration rate can reach 99.995%;
Bottom blowpipe design of material barrel with cyclone exhaust device for thermal drying barrel, to keep temperature and improvedrying efficiency;

The main body of honeycomb rotor is formed by ceramic honeycomb which is made from ceramic
fiber and organic addictive. Molecular sieve and silicone as basic material are crystallized and sintered
at high temperature for hard surface and tightly attached to the internal wall of honeycomb. Therefore,
it would not generate silt as barrel packaged or turntable molecular sieve to contaminate the plastic.
The honeycomb rotor can be used permanently and can be washed, while the ordinary molecular sieve
must be usually replaced for its easily getting saturate and aging. The water of moisture return air will be
quickly absorbed by molecular sieve when it across innumerable ostioles of the honeycomb rotor,

Therefore ,the air is completely dehumidified and reaches a very low dew-point. Regenerating and
dehumidifying happen simultaneously and follow the similar principle, except that their regeneration
air flows in the opposite direction.

Functions:
- Controlled by micro-computer to ensure stable and reliable operations.
- Un-crystallized PET materials are mixed by periodic speed to prevent formation in lumps.
- Crystallization efficiency is high and even.
- Raw material can be crystallized under high temperature.
- Equipped with storage hopper in the middle (option) and pneumatic valve to save feeding time and improve production efficiency.
- Overheat protection device can keep the operator and machine from accidents.
- Installed with power switch and emergency stop button to control security.
- Can work with dehumidifying dryer, and dry material directly.
- Can work with hopper, autoloader, magnetic base and suction box to feed materials.
- Using famous temperature controller, PID auto-temperature control. Precise temperature can be reached and controlled in +/- 1 Degree C.
- Installed with function of automatic power off with time.

Characteristic:
The machine operates extraordinarily efficiently by direct heat irradiation.
Energy consumption can be reduced significantly---1/3 of traditional dehumidifier
Final moisture: 70ppm
Drying time: 20mins
Infrared rotating drum IRD is the ideal alternative in the face of steadily rising energy costs.
The most important components are the radiator module within a horizontal rotating drum, which has an integral, welded, conveyor screw.
A volumetric metering unit, into the integral screw of the rotating drum, distributing it evenly through the dryer. T
The drying time depends on the rotational speed of the drum and is adapted precisely to the operational parameters.
At the end of the rotating drum the material falls into the output hopper and can be transferred directly to the next process step.

Applications:

Infrared rotating drums IRD - virtually unlimited and plastics and other industries.
Drying of plastic pellets (e. G. PET, ABS/PC, PC, LCP, wood-PP, PP/PE compounds)
Crystallisation 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 oligomeres and volatile components
Drying in the food, feed and pharmaceutical industries
Roasting of coffee beans.
