PLA Dryer at 50ppm by 20mins drying, PET Pre Crystallization Dehumidifying Dryer, PET crystallizer machine,polymer dryer
PLA is kind of very sensitive temperature material. PLA is a hygroscopic thermoplastic that easily absorbs water from the
atmosphere.
Even small amounts of moisture will hydrolyze PLA in the melt phase, reducing molecular weight and causing loss of properties. This can cause sheet brittleness, internal holes, sagging of the web at the die exit, or other process and quality problems. With PLA, proper drying is not optional. It is absolutely essential. Resin manufacturers recommend that PLA be dried less than 250 ppm before processing. In fact, moisture levels below 200 ppm may be needed in order to ensure a reasonable safety margin and, in some cases, moisture levels below 50 ppm are recommended.
Infrared dryer LIANDA Made can be used for drying a variety of plastic pellets, such as PBAT,APET, GPET, CPET, PLA, HIPS, PE, ABS, EVA ,PC, PEEK, PPS, PTFE, PEEK, TPU, TPE e.g.
We got German Patent on Infrared crystal dryer ( IRD) in 2008, and patent number is ZL201110032787.6
Infrared drying technology offers the ability to dry and crystallize materials in minutes, compared to hours with conventional drying equipment which reduces change over times significantly and reduces energy consumption at almost 45-50%, Also Infrared drying technology changes in moisture at beginning will dry pellets gently to a uniform degree within minutes, the final moisture can be 30-50ppm.
Our Advantage
|
Infrared Crystal Dryer
|
Conventional Crystallizer | |
| 1 |
Easy to clean and change color The drum can be opened completely,no hidden spots and can be cleaned easily with a vacuum cleaner |
Have to be completely disassembled,cleaned and fixed |
| 2 | Rotary drying system, its rotating speed can be increased as high as possible to get an excellent mixing of pellets. It is good in agitation, the masterbatch will not be clumped | Poor agitation,easy to be clumped |
| 3 | Can satisfy different type of Masterbatch (Drying temperature and time can be adjustable by the property of raw material) | The drying temperature is fixed |
| 4 | Crystallization time 15-20mins depends on the material kind | Need 4-6 hours or more |
| 5 |
Save about 40% energy consumption compared to conventional dehumidifier
