UMAi Dry® is specifically designed to work in a modern frost free kitchen refrigerator. Our instructions specifically recommend against using a dorm, wine, beer or other “cooler” type refrigerator as it is not designed to manage the cups and cups of water that the meat will be releasing into the internal environment of the fridge. Fan, desiccant, salt–none of these actually manage the humidity, and the meat will not dry.
UMAi Dry® also specifies that you need a manual lid and latch vacuum sealer. The vertical automated models that FoodSaver is pushing will make the application of UMAi Dry® vary frustrating. These automated models require the rigid laminate oxygen barrier embossed vacuum material that FoodSaver sells. UMAi Dry® is a single layer flexible membrane. It is not a vacuum bag, not rigid and not compatible with the design of these automated models.
If you don’t want to buy another vacuum sealer, you can follow Ballistic BBQ’s guidelines for sealer-free application of UMAi Dry®: umaidry.com/nosealer
Hope this answers the questions.
