Fridge-Door Smoothie Dispenser

Some refrigerators have built-in water and ice dispensers in the door. Convenience stores have slushy frozen drinks ready to be dispensed at any time. This idea combines the two.

The idea is to add a third dispenser nozzle, with a mechanism that leads to a removable canister in the freezer. Various food companies can sell disposable attachments filled with your favorite frozen goodies: soft-serve ice-cream, fruit smoothies, slurpees, frozen margarita mix, etc.

Ideally, the canister part of the dispenser would have its own individual temperature control (possibly using a mixture of air from the freezer and the refrigerator to keep the canister at the ideal temperature for the particular contents). For some drinks, an agitator mechanism (like those rotating blades in Slurpee machines) may be necessary.

I'm imagining a design that would be self-cleaning, using water diverted from the water dispenser, so there would be no need to take apart the third dispenser mechanism to clean it. The user could just twist off the old flavor, press a button to run some water through the pipes, and twist on a new flavor.

Even more fun would be if there was a reusable canister you could use to make your own home-brew frozen drinks, attach to the dispenser, and have at-hand for several days.

So, teens can have grape juice slurpees for after-school treats, college kids could twist on a "jungle juice" attachment for a party, health nuts can use it to dispense protein shakes each morning, pregnant ladies can create their own wacky flavor of soft-serve ice cream to auto-dispense for midnight snacks, and I could have frozen lemondade, vanilla milkshakes, and berry smoothies handy all summer. Yum!

I've been commenting on halfbakery for a while, and reading for even longer, and I thought it was time for me to write up one of my ideas! First post!
