Salad Lettuce Spinners also known as lettuce dryers are a must for any food service or restaurant operation. Zesco offers the Dynamic SD92 manual lettuce spinner and the electric powered Electrolux VSD-10 10 gallon, VSD-3 and the VP-1 20 gallon lettuce spinners. By using the lettuce spinner, one is spinning the water from the lettuce with centrifugal force. The end result will be dry lettuce. Dry lettuce will allow the salad dressing to cling to the leaves instead of dropping to the bottom. If serving wet lettuce, it will seem soggy. Clean dry lettuce will keep for several days providing it is properly refrigerated.
