Basic Principles Of Blast Chilling And Freezing

Current food legislation requires that all food must be cooled as quickly as possible. This means that whenever food is chilled or frozen, it must be in the "Danger Zone" between +8ºC and +68ºC, where bacteria multiply fastest, for as little time as possible. To achieve this, a specially designed Blast Chiller or Blast Freezer is required- standard refrigeration equipment just isn’t capable.
