An Experimental Study on the Storage Performance of Blueberries Using Precooler and Precooling Box

Blueberries are harvested and distributed in summer. Summer fruits are harvested and circulated at high temperatures, which increases the respiration rate of the fruit, causing retraction and overripeness. This problem is directly linked to fruit quality and price declines. Proper cooling after harvest will affect shelf life and transportability of fruits and help to improve farmers’ profitability. We conducted an experimental study on the storage performance of blueberries using a differential pressure precooler and a precooling box for the cooling of blueberries after harvesting. With this precooler and precooling boxes, we were able to lower the temperature inside the fruit sufficiently in 2 to 4 hours whereas the forced air blowing takes 12~24 hours. This means the differential pressure precooler is more helpful for summer fruit in rapid packaging and delivery.
