Infrared heaters used in crystallizer/dryer for PET recycle and re-use

What is Infrared Radiation?

Infrared radiation (IR), sometimes we called infrared light, is electromagnetic radiation with wavelengths longer than those of visible light.Infrared is located between the visible and microwave portions of the electromagnetic spectrum and shares many of the same properties of visible light. When infrared waves encounter a solid object they can be reflected (bounce off), diffracted (scattered), refracted (bent), transmitted (pass through), or absorbed by the object where several of these effects can take place at the same time. Depending on the wavelength and frequency, infrared is commonly divided into five categories as near-wave, short-wave, mid-wave, long-wave and far-infrared.

IR is also referred to as heat or thermal waves or electromagnetic waves.All materials absorb a fraction of the infrared spectrum,reflect a fraction at the surface and allow a fraction of the radiation to pass through. By selecting emitter with suitable spectra,the largest possible fraction of the radiation is absorbed in the material and converted into heat.As they have a heat-inducing property,infrared emitters are used in many applications where need heat processing.

Infrared heaters used in crystallizer/dryer for PET recycle and re-use

With the advances of technology, the controlled precision of infrared heat offers energy-efficient and cost-effective application for a wide range of industrial processes.For PET recycle and re-use,infrared heat is mainly used in crystallizer/dryer.

Infrared crystallizer/dryer is a slowly turning cylinder with a wide,shallow spiral channel on its interior, as well as paddles that stir the PET regrind as the drum turns. The helical channel gradually conveys the material along the axis of the drum. A stationary bank of Quickly infrared heating lamps tube hangs in the center of the drum and a stream of ambient air flows through the drum to carry off moisture that escapes the hot resin. As the material passes through the drum, it is exposed to infrared rays from banks of infrared lamps.The rays do not heat the surrounding air, but instead, they penetrate to the center of the individual pieces of material and drive the moisture to the surface where it is carried away by a stream of air. Uniform exposure to the rays is guaranteed by the tumbling of the material as it passes through the rotating drum.Resin passes through the drum in 8 to 14 min. In that short period of time, the PET is not only fully crystallized but is also dried to a substantial degree.It's a fast,economical way to crystallize and dry PET with infrared heating emitters.This technology uses no desiccant and you do not depend on the dew point of the process air to dry the material. You can reduce energy costs by up to 45% compared to using traditional crystallizer and dual bed dryer.
