Vacuum Cooling
Vacuum cooling is a rapid type of pre-cooling, which also helps preserve vegetables by putting them in an almost complete vacuum. The field heat and heat from the vegetables' biological processes are used as water changes to vapor and the vegetables become increasingly cooler. Vacuum cooling helps keep vegetables in good marketable condition while in storage. The most rapid deterioration in quality of produce occurs soon after harvest, so the quicker the produce is vacuum cooled, the longer it will retain its initial quality. Produce can be vacuum cooled just as readily when packaged. The container does not effect the vacuum cooling, as long as the container is not completely sealed. Most lettuce is now vacuum cooled, and almost any vegetable can be vacuum cooled.
The following is a partial list of vegetables that can be vacuum cooled:
  • all leafy vegetables
  • any type of lettuce
  • asparagus
  • bell pepper
  • bok choy
  • brussel sprouts
  • cabbage
  • carrots

V.B. Hook Vacuum Cooling Company has portable vacuum coolers and hydro-coolers available for cooling almost any type of vegetables. The units are transported behind a semi-tractor and can be set up anywhere a large truck can go. These portable units are powered by self-contained diesel engines. The entire machine is 45 feet long. The tube can be loaded with up to 6 pallets at a time. The cooling time for each load is between 15 - 35 minutes, depending on the type of produce being cooled. For more information call Timmy at 803-794-2875.
Note: We do not sell vacuum coolers. We provide a vacuum cooling service by bringing vacuum coolers to the customer's field or dock for use during their packing season.
