The machines in a bottling plant pump out almost 800 bottles per minute, utilizing specialized "air-veyor" belts to maximize efficiency. Canned Cokes are filled at an astonishing rate of up to 1,700 cans per minute in a process more complex than meets the eye. And, Coca Cola Company's worldwide supply chain is executed without ever revealing the beverage's famously secret formula.
