Vapor-Phase Oven

My Friends: Del the Cat, Abdel Halim Galala, Ried, Vulcan, Stirling Stan, Andey Germany, ietech, Wrenched and everbody - come help me out.

My internet here to slow...zzzzzzzzz to scan all sites at high speed & download data.

My knowledge of ovens is limited to kitchen and ink-drying.

I guess that they will run a web of paper through a series of rollers, and between the temperature and kerosene spray to remove water out of paper to reduce conductivity of the paper.

Thermal oil is used for heat to avoid any open flames near the sprayed oil. You might need a CO2 or inert gas fire suppression system.

I will also guess that air tight construction and ventilation control will be a challenge to pull water vapor out, and to keep ambient humidity out.

If I were trying to sound semi-intelligent, I would try to be or sound knowledgable on paper web handling (paper roller handling and rollers to move the paper from the out take paper roll to the take up paper roll). I would convince them that our plant tolerances are such that ventilation control will be tight, with no unwanted high humidity entering the oven. I would indicate a broad base of safety and loss prevention knowledge in meeting fire pretection concerns.

In other words, if you can't dazzle them with your knowledge, baffle them with your bull roar.

RRRRRRRRRRRRRRRRRR Thanks, I'll remember this.

Since everything will be provided by their Supplier(complete Plant to assemble) and we'll be responsible for the fabrication of the oven body/doors/ducting etc., so I'm concentrating more on the workshop facilities to convince them that we have the capability to do the job. On the working part it is their responsibility so I'll act dumb and only expose with the slight knowledge on principles of vapor-phase based on whatever little writeup I collected from the net, just to give them the idea that I'm aware of the technology.

Thanks Ried

I believe Dirty Harry Callahan said "A man needs to know his limitations."

I thought you already knew mine.

One thing I missed is it is a vacuum process, so temperatures could be lower. However, I would guess the trade off is heavier wall and structural construction. I also missed reading that this is a batch process, so my comments on web technology do not apply.

Now you know why I smile so much.

One other thought, check TAPPI.org for information on paper and paper processing. They might have technical data on control of water content of paper.

No problem. Always high regards for you. Thanks
