Summary

Precooling enabled longer shelf-life for postharvest horticultural products, but the implementation for peach fruits was hardly studied because they were only tolerant with the air -based methods which were either time-consuming or energy-intensive. Lab-scale experiments were conducted using around 400 kg Okubao peach fruits with typical postharvest package to evaluate the performance for forced-air cooling. An energy-saving operation strategy was proposed with the interruption of high-power centrifugal fan and the use of low-power axial fans to generate more airflow at the inflow surface of stacks. In comparison with the original forced-air cooling method, the energy-saving operation resulted in 8.13% lower energy consumption, while 4.19% and 8.26% increase of mean and maximum seven-eighths cooling time was obtained respectively.
The energy-saving operation strategy achieved the energy consumption reduction at the expense of prolonging the cooling time. Therefore, it could be used when the short cooling time was not the main concern.
