Abstract—Various factors cause fruits and vegetables spoilage. Sufficient ventilation, heat, light, humidity or temperature may affect both safety and quality of those fruits and vegetables.

To prevent the situation that the fruits and vegetables are unsuitable for consumption or they decay or go bad quickly, keeping sensitive items in proper temperature-controlled storage system is recommended. Let-It-Cold design concept has been introduced in this study where the space and layout between containers used for keeping fruits and vegetables fresh and crisp are the key considerations. For small-sized cold room, arranging containers/crates properly to keep produce fresh much longer than other traditional ways will be reported and analyzed. Three layout designs for positioning and stacking a crate containing 25-kg tomatoes are considered and compared.  Ergonomic design for people at work; depalletizing operation was applied in this study as the guideline to design the proper height of the stacked crate in column. For each storage shape, computer fluid dynamics (CFD) has been applied as the tool for cold room analysis. Then, a newly proposed performance index is used to compare and choose the optimum design layout from the simulation result.
