Onion dehydration consists of a continuous operation, belt conveyor using fairly low-temperature hot air from 38 - 104 deg C. Typical processing plants will handle 4500 kg of raw product per hour (single line), reducing the moisture from around 83% to 4% (680 to 820 kg - 1,500 to 1,800 pounds of finished product). An example of a geothermal processing plant is Integrate Ingredients at Empire, Nevada, in the San Emidio Desert. A total of 6.3 million kg (14 million pounds) of dry product are produced annually: 60% onion and 40% garlic. A 130 deg C well provides the necessary heat for the plant
