We do not bake any of our boards prior to wave solder. If we did we would have one heck of a large oven. I would assume you are concerned about moisture sensitive components. In most cases your top side parts should only get to 80 degrees centigarde

Chipbonder is best applied with a stencil. Too bad on the dispenser purchase. Little hint, use a Kapton Stencil. You can have them laser cut and can get them as thick as you want. Another advantage is the ability to make shapes etc for cleaning

I have used Balston (www.parker.com/balston) for desiccator cabinets in the past and really liked them. It's the only brand I've used so can't comment on how they compare with anything else, but it was certainly easy to use (hook up 100psi and dial
