Having the right Vacuum Cooling Systems in food processing is the need of the hour for keeping growers’ produce fresh.
What is Vacuum Cooling?
The 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 process of vacuum cooling works in the following way:
A product is placed into a chamber where the pressure is initially equal to the ambient atmospheric pressure approximately 1000 millibar. The pressure in the chamber is reduced causing the boiling point of water (100°c @ approx 1000mb) to change to a lower temperature, thus the water present in the chamber will begin to change state and produce water vapour. For the water in the chamber to change to a vapour it needs energy to perform a latent heat change. This energy is taken from the produce itself therefore removing heat from the produce and cooling the produce.
Some of the best-suited products in vacuum cooling systems include lettuce, celery, broccoli, Beans and sweet corn.
Vacuum cooling is known for its energy efficiency because all the power is used for keeping the farm produce fresh and cool.
Benefits of Vacuum Cooling
In comparison to the traditional methods, vacuum cooling is relatively quicker and a great choice for keeping crops fresh and cool for a long time. Here are some of the common benefits of using vacuum cooling systems:
- It offers rapid cooling due to the integration of the latest pre-cooling technology by Quik-Cool for outstanding speed with a great drop in temperature in about 30 minutes.
- Due to balanced pressure at every step within the vacuum chamber, there is even cooling throughout for the contents.
- There is no need to manually operate the vacuum cooling systems as they have intelligent technology to sense the outside temperature and make it energy-efficient.
Choosing the right Postharvest Cooling System
It is essential to choose the right vacuum cooler based on your requirements. Each will have a different degree of power, capacity and geometry. However, some of the common features of the Quik-Cool finest Australian-made vacuum cooling systems include portable units, automated chamber doors, automatic pallet unloading and loading as well as superior track record software for controlling vacuum cooler performance with remote monitoring.
