Abstract
The total area under pistachio crop was reported more than 250,000 Hectares with production 350,000 Tons in the years 2002-2003(). In Iran, unhulled pistachios are traditionally shipped from the orchard to the processing terminal by truck and trailer.
Pistachio nuts may stay in the transporting vehicle for several hours.
Research results have shown that the temperature of pistachio bulk held in parked transporting vehicle rapidly increases.
In long wait periods unhulled pistachio nuts can be damaged.
Therefore in this condition pistachio nuts must be held cool.
Researchers have shown that agricultural products with high moisture content heat when held in parked transport vehicles and air flow induced by transport or by fans can be used to cool them.
In this study an unhulled pistachio mesh sided transport trailer designed and evaluated.
This trailer has two floors to reduce pistachio nuts layer compression and to improve air circulation inside pistachio bulk.
This decreases bulk temperature in comparison solid sided ordinary trailers.
This trailer can carry an equal product with the same cost in comparison with conventional trailers.
The trailer was tested after being designed and manufactured and its operation evaluation was acceptable.
Temperature of bulk was measured in mesh sided and solid sided trailers for 48 hours.
Results indicated that unhulled pistachio nuts that was transported with mesh sided trailer were cooler about 8.08°C in lower floor and 9.33°C in upper floor than those that were transported with solid sided trailer.
