Hydro Cooling makes a great introductory method to remove the field heat from the produce and is very efficient in terms of cooling time. By chilling the produce immediately after harvest, hydrocoolers combat the factors influencing field heat, external factors and the plants respiration rate.
‍
A hydrocooler produces chilled water and then moves this water into contact with the produce. Subsequently, a pump moves chilled water to cool warm produce, which is then re-cooled to be used again.

There are various types of Hydrocoolers in terms of how they can be utilised, Hydrocoolers that transfer produce on a conveyor and pass it through a Hydrocooler where they are sorted and packed in a production facility after passing through the hydrocooler, the volume of product to be processed per hour determines which option is viable.
