Certain types of vending machines are capable of squeezing oranges and dispensing the freshly-squeezed orange juice right there at the machine. Generally speaking, these machines actually show you the oranges through a transparent window, so you can see the orange-juice-making process.
Most of these machines proclaim that you are getting “100% Orange Juice” or “All Your Vitamin C,” but typically they don’t bother to tell you that the orange juice is fresh—after all, you can literally SEE the oranges being juiced, so there’s hardly any room for confusion. The machines typically look something like the illustration in Figure 1.
Since the machines don’t always say that they are actually squeezing the oranges, it might be possible to have a magic-trick-style arrangement where the oranges go into an opaque grinding mechanism and then orange juice is dispensed—the customer will naturally infer that the oranges are being squeezed in the opaque mechanism, but what if this were not ACTUALLY the case?
Figure 2 shows a proposal for a system that keeps the oranges safe and sound (they could even be plastic oranges), while still appearing to squeeze them.
People usually enjoy food more if it looks good: orange juice that comes from a fresh source will probably be appreciated more than orange juice that comes from a huge drum labeled “50 GAL. LIQUID ORANGE PRODUCT.”
With this “placebo effect” in mind, maybe it’s not you who are to blame for mis-labeling your from-concentrate orange juice, but rather the customer’s taste buds!
PROS: Possibly more eco-friendly, as it allows orange juice to be transported in concentrated form, rather than in bulky whole-orange form. “Placebo effect” of the orange-squeezing process may increase perceived flavor of the orange juice.
CONS: Any claims of “freshly squeezed” oranges could run afoul of product labeling laws in your jurisdiction—word your vending machine text carefully! As always, consult a lawyer before perpetrating blatant anti-consumer fraud on your customers!
