Vacuum cooling is the rapid evaporation of water in a vacuum processing chamber at a lower temperature under vacuum conditions. In the process, more heat is consumed, and in the absence of an external heat source, a cooling effect is generated in the vacuum chamber. The vacuum pre-cooling technology is simple in principle and high in cooling rate, and is widely used in vegetable products preservation, transportation and storage .A vacuum cooler represents a significant investment. However, the fast cooling times achieved may preserve quality and extend storage life. This is particularly important for products such as baby spinach or lettuce, but may also be critical for broccoli during warm harvest conditions.
