Global Cooling Inc., is touting success of a forced-air cooling system that cuts the time required to cool cherries.
The Media, Pa.-based forced air cooling systems company conducted tests of its jet precooler in two grower-packer sheds in Wenatchee, Wash.
The trials showed the equipment cooled the cherries, packed in bags, clamshells and 18- and 20-pound cartons, in one hour compared to the normal 8-10 hours required for cooling, according to a news release.
In cherry packinghouses, cooling fans typically use 40 horsepower hours of electricity compared to the 18 horsepower hours used by the jet cooler, according to the release.
“If we have 8 times as much airflow, or cfm, per-pallet, then we will cool 8 times as fast. It’s as simple as that,” Jim Still, founder and president, said in the release. “The cherries have much longer shelf life, there is greater net weight for retailers to sell, the fruit is more disease-resistant, the fruit stays pretty and doesn’t wrinkle so much, and it just goes on and on and on.”
The system’s other benefits include reducing the number of tractor trailers backed up in packing operations’ yards and some of the packinghouse’s controlled atmosphere rooms can be turned off or used for additional cold storage of apples and pears, according to the release.
