Vacuum Cooler has been used for many years to rapidly cool  Fresh Produce and Post Harvest Produce ( flowers, vegetables, fruits). 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.The vacuum cooling method of cooling is extremely fast reducing cooling times to minutes instead of conventional cooling which can take many hours. This means that food is fresher and lasts longer.
