Yes you can pack the Volcano away within a few mins of unpluging it. I have owned my digi Volcano for a few years now. I only pack my Volcano up when I want to use it at a friends house, and I usually unplug it once I fill the last bag we gunna "smoke" and once the bag is empty, I pack my Volcano back in the box (styrafoam and all) and have NEVER had any problems (and yes I know I need to get a travel bag or box for my Volcano instead of the box).
As far as a good temp to use you 'cano at, I usually start around 335 and adjust up from there (usually ending around 360-380 to "kill the "bowl". I usually never go higher then that since I like to use the Vapoo to cook with).
Hope this helps:thumbsup:
