blanketing with nitrogen

I think this gets closer to the root meaning of 'Schleierung'

flooding with nitrogen

Well, this is a guess, but you might find more info at the site, where I found:

" In order to achieve Atex compliance, it makes sense to flood the product chamber with pure nitrogen. This is done prior to starting the dryer and filling it with product. During the drying process, the product is also flooded with a layer of nitrogen (between 5 and 30 m³/h). The nitrogen layer enhances the drying effect, as the gas serves as a carrier for the humidity."

Good luck.
