Vacuum Cooling and Hydro Cooling have been used for many years to rapidly cool product in the Food and Catering Industry (cooked food and meals , bakery products, bread) and also in the Fresh Produce and Post Harvest sector ( flowers, vegetables, fruit).
The vacuum cooling process works by the rapid evaporation of water from produce under low-pressure situations. During the process energy in the form of heat is required to change water from a liquid to a vapour, this action is the principle of vacuum cooling.
Hydro cooling with Alltech Hydro-Vac coolers operate over a wide range of produce that includes Snow peas, Cherries, Sweet corn, processed vegetables and pasta. Hydro cooling with Hydro-Vac are the same as the standard vacuum cooling products with the addition of sprays bars and water reticulation system.
