“How Long Will it Take to Cool My Product?”


We are often asked questions such as:  “How long it will take to cool my melons? 

Or, “Can you tell me how long it will take to cool 20 Metric tonnes of seedless grapes from 30C to 4C?". 

So we posed the same questions to Jim Thompson, and here is his reply.

"The Answer Is:  Cooling time is related closely to product diameter. 

Small diameter items such as berries can be cooled in 1.5 hours on average; larger fruit such as tomatoes and peaches might require 2 to 3 hours, and melons need at least 4 to 6 hours of cooling time. 

Cooling time will be longer than these estimates if there is:

1) inadequate refrigeration capacity,

2) poorly vented boxes or internal packing material that restrict airflow,

3) too much product is placed in the cooler,

4) your staff fails to properly load and operate the precooler,

5) the product is hotter than usual, or

6) other variant."

Our Jet-Ready Intermodal Precooler™ enables you to inexpensively start to precool, and learn as you do.  

If all other factors are equal, higher airflow at static pressure is better, and the Jet Precoolers™ offer world-class airflow at high static pressure.  We often see ROI of 7 weeks or less. Sometimes, a Jet pays for itself with just one use.
