Abstract:
Described is a method as well as an apparatus for vacuum cooling of food produce through moisture removal, which method comprising the steps of loading the food produce to be cooled into a vacuum chamber, lowering the pressure inside the vacuum chamber to a predetermined pressure level and maintaining the vacuum chamber at this predetermined pressure level both by removing air through a vacuum pump system for a sufficient of time to allow heat transfer out of the food produce to take place, and condensing water vapor inside the vacuum chamber through a refrigeration system. The method and apparatus is unique in that the step of lowering the pressure inside the vacuum chamber to the predetermined pressure level is carried out using a single stage vacuum pump and the step of maintaining the vacuum chamber at this predetermined pressure level is carried out using a two stage vacuum pump.
