PET Infrared Crystallization Dryer (HWJG)

IRD Heats Material From Inside

Infrared (IR) operates in the same manner as the heat from the sun so unlike conventional driers only the solid or liquid mass is heated not the surrounding air which remains cool. IR causes molecular heat oscillation directly to the core of the material so vaporising moisture which is absorbed and removed by the cool air. Desiccant dryers work in reverse, the surface is always hotter than the core consequently as soon as it is in ambient air the surface cools and absorbs moisture.

Applications

Crystallising and drying of PET regrind from sheet, film or bottles;

Drying of virgin PET;

Pre heating and drying of free flowing powders;

Pre heating and drying of wood / PP;

Blends of regrind, virgin and additives;

Biodegradable PVOH;

Hygroscopic thermoplastics;

Due to the speed of moisture removal by IR acting directly at the core of the material energy consumption is low. Typically for PET the power required is 120 watts per kilo per hour.

1. Low energy consumption, producing PET-400g/h consumes about 39kw/h; Electricity, 50% energy saved;

2. About 30 to 40 minutes’ dehumidifying crystalization, completed once for all;

3. Water ratio of dehumidifying crystalization products is 70ppm-110ppm;

4. Less power generated;

5. Easy to change raw materials and clean, taking only 30 minutes;

6. Little occupancy, simple installation;

7. Applicable for all plastic products.
