Manufacturing Companies for China Plastic Infrared Crystallization Dryer - PET Masterbatch Crystallizer dryer/Polyester masterbatch/ Plastic masterbatch dryer/Plastic dryer – LIANDA Detail:

Application Sample

Raw Material	Polyester/PET Bright Masterbatch (Bright color masterbatch: polyester spun from polyester chips with a TiO2 content of less than or equal to 0.1%. It is one of the conventional varieties of polyester. The quality index of the slices is the same as that of semi-dull polyester and full-dull polyester. The crystallization rate is slower than that of semi-dull polyester and full-dull polyester. It is easy to stick when drying, and the temperature should be controlled. Aurora will be produced under light exposure.)
Using Machine	LDHW-1200*1000
Crystallization Temperature set	95℃ first zone; 130℃ second zone, 150℃ third zone
Drying time set	25mins
Final product	Dried and crystallized Polyester masterbatch no clumping, no pellets sticking

How to Work

>>At first step, the only target is to heat up the material to a preset temperature.

Adopt relatively slow speed of drum rotating, the Infrared lamps power of the dryer will be at a higher level, then the PET pellets will have a fast heating till the temperature rises to the preset temperature.

>>Drying step

Once the material gets to the temperature, the speed of the drum will be increased to a much higher rotating speed to avoid the clumping of the material. At the same time, the infrared lamps power will be increased again to finish the drying. Then the drum rotating speed will be slowed down again. Normally the drying process will be finished after 15-20mins. (The exact time depends on the property of material)

>>After finishing the drying processing, the IR Drum will automatically discharge the material and refill the drum for the next cycle.

The automatic refilling as well as all relevant parameters for the different temperature ramps is fully integrated in the state-of-the-art Touch Screen control. Once parameters and temperature profiles are found for a specific material, theses settings can be saved as recipes in the control system.

Our Advantage

1	Instantly	The production run can start immediately upon startup. A warm-up phase of the machine is not required.
2	Can satisfy different type of Masterbatch	Drying temperature and time can be adjustable by the property of raw material
3	No clumping, no sticking	The rotation of the drum ensures constant movement of the material.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 The product is evenly heated
4	Easy clean and change colour	Good access to all components allows for easy and fast cleaning. Rapid product change-over.
5	Minutes instead of hours	The energy is immediately brought into the core of the product
6	Save 45-50% energy cost compared with conventional dehumidifier& Crystallizer	Significantly lower energy consumption compared to conventional processes, through the direct introduction of infrared energy to the product
7	Siemens PLC control	Control.The process data, such as material and exhaust air temperature or fill levels are continuously monitored by means of sensors and pyrometers. Deviations trigger automatic adjustment. Reproducibility.Recipes and process parameters can be stored in the controlling system to ensure optimal and reproducible results. Remote maintenance.Online service via modem.

Material Free Testing

Our factory has build Test Center. In our Test center, we can perform continuous or discontinuous experiments for customer’s sample material. Our equipment is furnished with comprehensive automation and measurement technology.

• We can demonstrate — Conveying/Loading, Drying& Crystallization, Discharging.

• Drying and crystallization of material to determine residual moisture, residence time, energy input and material properties.

• We can also demonstrate performance by subcontracting for smaller batches.

• In accordance with your material and production requirements, we can map out a plan with you.

Experienced engineer will make the test. Your employees are cordially invited to participate in our joint trails. Thus you have both the possibility to contribute actively and the opportunity to actually see our products in operation.
