What Should You Know About Vacuum Cooling?
  • What is it?
  • Vacuum cooling has emerged as a unique
    cooling technique, which is based on the
    principle that the boiling point reduces with a
    reduction in the vapor pressure on a liquid. In
    this technique, the latent heat of the water in
    the cooled product is removed, which leads to a
    rapid decrease in temperature.

What Should You Know About Vacuum Cooling?
  • How Does it Work?
  • Once the food is put into the vacuum cooler, the
    pressure inside the cooling system is constantly
    decreased, leading to the continuous evaporation
    of the free water in the product. This
    evaporation takes place at a temperature
    corresponding to the boiling point.

4
What Should You Know About Vacuum Cooling?
  • How Does the Water Escape?
  • When the process of precooling starts and a lot
    of pressure is applied, the water present in the
    interior of the product migrates to its surface,
    through boiling, and then finally evaporates.
    Thus, making the cooling considerably shorter.

5
What Should You Know About Vacuum Cooling?
  • Advantages of Vacuum Cooling
  • Since the vacuum chamber has a balanced pressure,
    the evaporation takes place evenly. Hence, the
    food items are cooled uniformly, both externally
    and inside. For leafy vegetables, the temperature
    can be reduced to 4-5 degrees in 20-30 minutes,
    even after packaging. Thus, it allows for fast
    cooling.

What Should You Know About Vacuum Cooling?
  • Application of Vacuum Cooling
  • Vacuum cooling food items, especially vegetables
    like leafy greens, cabbage, lettuce, spinach, and
    celery, have proven to keep them fresh and extend
    their shelf life. A vacuum cooler is also applied
    for rapid cooling of high-temperature cooked
    food, before the packaging process.

7
What Should You Know About Vacuum Cooling?
  • Why Should you go for it?
  • Vacuum cooling is the most effective cooling
    technique for harvested fresh vegetables and is
    very important for maintaining their post-harvest
    quality.
