317069 - I'm not to concerned with minor differences between inside/outside air temp/moisture. We experience larger changes on a day to day basis just due to the changing weather patterns. The temperature on the drying system is controlled by the outlet air temperature. Depending on feed...
@Willard3 - it is a BI, but this will NOT be used for pressure control. This would only be throttled down if for some reason the building was no longer under pressure. The intake fans would be throttled to maintain the positive pressure we are aiming for in the factory.

@chicopee. The majority of things are automated in our factory, but being southern Florida, it's unbearable to even walk around in here in the summer time with both dryers, pasteurization, and our steam injection heating the product upto 200'f. Hence the ventilate the whole plant plan...
Currently, there is no ducting in the factory. We have several large intake fans near the ground, and several exhaust fans located near the ceiling to duct heat out of the factory. These aren't enough, so we are looking at adding additional intake and exhaust fans.
The dryer pulls air from...
I should have mentioned, this is a food processing facility in Southern Florida. This incoming air will need to be filtered, but that is it for 'conditioning'.
It's currently ducted to the outdoors. The purpose of this dryer is to dry a food ingredient for final processing. This dryer runs nearly constantly during the season, only shutting down for cleaning, maintenance, and power outages. The pressure would be regulated by the intake fans / PLC...
We are working on improving the ventilation to our factory. Our current dryer runs at a constant 45,000 cfm when it is running. I was looking at ducting this into our factory to act as 2 exhaust fans. Being a food grade plant, we maintain positive pressure of roughly .2" wg, to maintain this...
