Today at DEMO, a startup company MooBella announced its on-demand Linux-based ice cream vending machine. You can select among 12 different flavors and 3 kinds of mix-ins per machine. First field tests will be in Chicago this year, and the company is fundraising for deployment.

Another food product vending company on my radar is Wonder Pizza, which controls the U.S. rights for an Italian manufactured pizza vending machine. There are three different types of pizzas per machine, the pizza takes an average of two minutes to cook via a toaster oven (no microwave), and suggested retail is $5-6 per pizza.
