Microwave dry system
(Environment-friendly + Energy-saving)

SANGWON establishes itself as an environment-friendly & energy-saving microwave dry system manufacturer that takes lead of the relevant field, thanks to the support of its clients, since successful implementation of a pilot project to locally develop industrial microwave dryer as part of the government-led energy saving R&D program in 2000, followed by successful delivery of a large-size 400 kW dryer to an automotive material plant in 2002.

When applying microwave so as to be injected to internal of a dielectric material (±), the microwave is converted into heat as water molecules in the moist material rotate and vibrate synchronously, resulting in friction between the polar molecules. It is a self-heating mechanism inside the material, escalating extraction/diffusion of water molecules over the material surface. Our technology achieves high efficiency in converting microwave field energy into heat energy, meaning that a perfect degree of drying is accomplished with a very short period of time. Furthermore, it significantly resolves many problematic issues the conventional drying technology has, such as surface shrinkage, surface curing, occurrence of cracks, moist residues and bubbles. This solution ensuring innovatively improved quality and productivity as well as the comfortable and safe workplace is widely applicable to the drying process in various industrial fields.
