Effect of tight-stacking bins on fruit temperature reduction.

Cooling performance was compared in conventionally stacked and tight-stacked cold-storage rooms in trials with Anjou [Beurre d'Anjou] pears in 1995-96 and 1996-97 in Oregon, USA. The storage rooms measured approx. 18.6 x 9 x 7.6 m (length x width x height) and were packed with 825 bins (conventionally stacked) and 945 or 1049 bins (tight-stacked). Each room was instrumented to measure refrigerant temperature into and out of the evaporator coil (located above the door), air temperature at 3 locations, and fruit temperature at 26 locations. The results indicated that fruit cooling was not uniform in either room and suggest further studies are required documenting air movement patterns within both conventionally and tight-stacked storage rooms. Increasing storage capacity by tight-stacking bins had no adverse effect on overall fruit mass loss during storage or on fruit firmness.
