PET Flake Crystallizing, Drying Equipment

　

 

PET Flake Crystalizing, Drying Equipment – Comparison of Infrared v.s Traditional

Item

Infrared

Traditional

Heat transferring medium

NO need

Hot Air

Heat transferring way

Plastic material is dried inside and outside at the same time

Plastic material is dried from outside to inside gradually

Energy consumption

Energy saving 20~50% or even more

Larger energy consumption

Processing time

1) Crystalizing, Drying: around (8~15 minutes)

2) Dehumidifying, Drying: around (1~1.5 hour(s))

1) (ONLY) Crystalizing: around (30~60 minutes)

2) Dehumidifying, Drying: around (4~6 hours)

Moisture content

1) After (8~15mins) Crystalizing, Drying: lowered to 100~500PPM

2) After (1~1.5hr(s)) Dehumidifying, Drying: lowered to 50PPM

1) After (30~60mins) Crystalizing:

only transferred un-crystalizing PET into crystalized PET

2) After (4hrs) Dehumidifying, Drying: lowered to 200PPM

3) After (6hrs) Dehumidifying, Drying: lowered to 50PPM

Pre – processing

It takes only 8~15mins; or no more than 1.5hrs for the next processing procedures

It takes at least 6hrs for the next processing procedures

Material Changing

1) Only 1~1.5hrs of feeding volume stocked in the dryer

2) So, material can be changed very rapidly

1) At least 5~7hrs of feeding volume stocked in the dryer

2) So, material can be changed very difficultly

Operation

Easy

Very complicated

Maintenance

1) Easy

2) Maintaining cost lower

1) Difficult

2) Maintaining cost higher

Space required

Occupied space smaller

Occupied space larger

 

Why do we need this production line?

1) Due to PET’s characteristics of strong hygroscopic capability; it’s necessary for PET to proceed to drying before next processing procedures!  Besides, PET FLAKE all is the un-crystallized material!

2) If we are using the traditional dryer to heat directly, then the material will become “lumps” in the dryer.  In general, PET vitrifying temperature is about 800C; so, it requires stirring continuously while drying by traditional dryer!   Therefore, we recommend using infrared crystallization dryer to dry PET FLAKE.

3) In order to comply with the tendency of “GREEN/Environment-Friendly”, we should not promote the traditional types of equipment; we should strongly suggest the advanced styles of equipment in order to achieve lower consumption in energy, manpower; to save time and plant space and to reduce the pollution!!!
