Summary

In China, the production of perishable foods has reached 10 000 000 000 tonnes annually. Due to the low performance of refrigerated transport equipment and improper operation, 15 to 30% of perishable foods go rotten, costing €10 000 000 000 p.a. Infiltration can change the temperature and humidity of a refrigerated container (reefer) affecting food quality and transportation energy. Transport velocity is generally not considered a factor in food quality, except in allowing reduced transport time. The effect of transport velocity on infiltration was investigated using a refrigerated transport simulation testbed. The aim was to quantify the effect of leakage into the reefer at varied transport speeds to determine the level of infiltration occurring. A relationship between infiltration and transport speed was found to be approximately a positive linear relationship. Because different reefers will have different leakage characteristics new coefficients will need to be derived for each reefer. However, this relationship is always likely to approximate to a straight line with a positive slope.
