    Infrared Rotary Dryer For PET Plastic Wave Corrugated Roof Tile Extrusion Machine


    ----- To Dry and Crystallized PET Chips/ Flake before fed to Extrusion Production Line


    >> Crystallize and Drying PET Flakes at one step

    >> Drying time 20mins

    >> Final moisture can be 50-70ppm

    >> Save 45-60% energy cost :

    FLAKE0.15 KW / KG,HR (Crystallization & drying)

    Advantages for your process

    Low energy consumption.Significantly lower energy consumption compared to conventional processes, through the direct introduction of infrared energy to the product.

    Minutes instead of hours.The product remains for only a few minutes in the drying process and is then available for further production steps.

    Instantly.The production run can start immediately upon startup. A warm-up phase of the machine is not required.

    High efficiency.The energy is immediately brought into the core of the product.

    Gently.The material is heated gently from the inside to the outside and not loaded from the outside for hours with heat, and thereby possibly damaged.

    Easy cleaning.Good access to all components allows for easy and fast cleaning. Rapid product change-over.

    In one step.Crystallization and drying in one step.

    Increased throughput.Increase of plant throughput by means of reduced load on extruder.

    Evenly.Ensures a constant discharge


    How Infrared Crystal Dryer Dry?


    Features of infrared dryer (IRD)


    >>The infrared crystal dryer is the latest drying technology developed at present, and the infrared crystal dryer only needs 8-20 minutes, crystallization and drying are completed at one time, saving time, electricity, good drying effect, convenient maintenance and low cost, which is the highest efficiency at present , The best choice for low energy consumption drying method.


    >>There are three P.I.D temperature control zones, and the crystal drying temperature can be set according to the characteristics of the raw materials.


    Infrared principle

    Infrared principle


    The frequency of infrared is about 1012 C/S ~ 5x1014 C/S, which is part of electromagnetic wave. Near infrared wavelength is 0.75~2.5μ and travels straight at the speed of light, and it goes around the earth seven and a half times per second (about 300,000 Km/s). It can be seen from the light source It is directly transmitted to the material to be heated, causing physical phenomena of absorption, reflection, and transmission.


    In addition, the infrared rays that penetrate and reflect from the material do not affect the organization of the material, but the absorbed tissue will be converted into heat energy due to molecular excitation, which causes the temperature of the material to rise. Taking PET as an example, crystallization and crystallization can be achieved in a very short time. The drying temperature can not only save energy, maintain the physical properties of liposomes and increase the IV value.


    (The argument to increase the IV value (intrinsic viscosity) needs to be further verified by experiments.)


    Infrared Crystal Dryer


    Convective heating


    1

    Infrared drying(IR ) :Heat is adsorbed inside the pellets.Plastic and water are excellent IR adsorbents.

    It takes about 15 to 20 seconds to heat a pellet entirely


    Convecting Drying :Heat conducts into the pellet,plastic is a poor heat conductor.

    It takes about 30-50 minutes to heat a pellet enturely



    Water vapour moves to the coolest area,IR heating starts inside the pellets and immediately heat is conducted towards the cool ambient air.In this

    phase the moisture is heated and vapourised immediately and is arracted out of the pellet into the cooler ambient air


    Vapourised water moves to the coolest area,convective heating starts at the surface of the pellet and slowly heat is conducted towards the center.In this phase the moisture is attracted towards the cooler center of the pellets.Drying doesn't even start.What is more the moisture concentration inside the pellet increases




    Heating difference principle explanation


    The physical force for moisture diffusion is a difference in temperature and a difference in partical pressure

    1)IR-provides a high vaporisationrate on moisture in the core

    2)The driving force for diffusion is a difference in Temperature between the vaporised moisture and the

    ambient air

    3)IR used cool ambient air so a permanent difference in partical pressure is always avaliable

    T particle > T ambient

    P particle > P ambient

    when the entire pellet has reached the same temperature as the hot ambient air drying starts:

    1)vaporisation rate is low

    2)Vaporised water is transported from the core of the pellet to the surface

    3)The driving force for this diffusion is a difference is partial pressure of the ambient air

    4)To ensure this process is effective desiccant air with a low dew-point is applied generally.


    How To Work


    1. Material Feeding 2.Rotary drying system ---Drying & Crystallization 3.Discharging


    Material Feeding

    The flake or scrap will be fed to Rotary drum by Vacuum feeder or screw feeder


    Rotary Drying System

    Drying&Crystallization in one step. By rotation of the drum, the material is mixed by various mixing elements,optimized to your material. The material is thereby thermally treated. The thermal treatment is completed after a defined period or after a specified required temperature is reached.


    Discharging

    The thermal treatment is completed after a defined period or after a specified required temperature is reached. For discharge, the direction of rotation of the drum is reversed. Then the material will be discharged
