I want to build a faster oven for drying plastic sheets. I currently us an 8'x8' low temp gas oven but need to dry more material faster. I've seen info on a woodworker that built a Microwave dryer for large wood projects and wonder if the same technology can be used to dry plastic. A major concern of course is containing the microwave radiation. I'm open to any safe ideas.
It can be done, and done safely, although microwaves might not be the best source of energy for that particular application. Radio frequency energy might be a better choice. Unfortunately, this forum isn't really the best place for a detailed discussion. Click the source link below and feel free to make contact.
I think the microwave oven frequency will quickly evaporate water from the surface your plastic, but not other liquids, that contain no water. A specific frequency is best for evaporating each kind of liquid, so perhaps you can use multiple frequencies. I tried drying some wet kindling wood with our microwave oven, and was disappointed in the results, so perhaps what you heard was an exaggeration. Neil
