I built this last week for the next project coming in. It holds dry ice pellets in the chamber and with the aid of a computer fan, blows chilled air over the scoop while it's on the set to help keep it from melting.

Interesting. I always like to see how things are done BTS. Does this device function without putting visible fumes into the shot?

Yes...the fan just blows air over the dry ice so what comes out the end is simply cold air. Any 'fumes' from the dry ice dissipate (evaporate?) quickly.The old school way of doing this is to hold a colander filled with dry ice directly over the scoop and let the cold air cascade down. And while that works reasonably well, any air movement in the room (strobes/air conditioner) has pretty large affect on that falling air. This gun provides a bit of 'force' from the fan to keep it concentrated on the scoop.

And to provide a little sense of the scale of the project coming up from just a logistics point of view: I need to accommodate about 250 1/2 gallon containers of ice cream in freezer space. It gets complicated because it needs to be in the freezers for a few days at -5° in order to temper, so I can't shuttle it between different places. I currently have 3 stand alone freezers as well as 2 that are part of refrigerators but suspect that i need to have more and I'm wishing my math skills were better in trying to figure out exactly how many cubic feet of storage the product requires. :cry:

Here's a scoop that's being worked on in the cold box...a styrofoam box packed with dry ice on sides and above, with a hinged door. Work a little, close the door to re-freeze...repeat.

I put in a couple years at the local Baskin Robbins Ice Cream Parlor as a teen - developed Popeye like forearms in the first three months. Still got 'em, give me a shout if you need some help ;-)a
