Expériences comparatives sur trois engins de transport routier à parois minces et un traditionnel.

Comparative experiments on three thin-wall and one conventional road vehicle.


Type d'article : Article, Article de la RIF


In 1984 international research took place which compared the transport conditions of quick-frozen foods in thin-wall vehicles and conventional vehicles. This work was done at the request of the group of experts of the UNECE/TRANS/GE.11 in Geneva, Switzerland. In the Netherlands measurements have been carried out on three road vehicles one conventional and two thin-wall vehicles - in the test station and on the road. The road transport involved taking a commercial cargo of frozen fish from Holland to Italy during the summer (July). Later on an additional test was performed in the test station with a fourth thin-wall vehicle at an ambient temperature of 30°C. The results show, that in the conventional vehicle, equipped with a bulk head and a ceiling air duct, and working on a temperature setting of -25°C, a maximum product temperature of -18°C could be maintained. The maximum temperature difference in the cargo was 6 K. Thin-wall vehicles appeared to have a temperature difference of 12 K between air inlet temperature and warmest product temperature. The maximum product temperature could be held below -12, -15 or -20°C, depending on the air distribution and, in particular, on the cooling power of the thermal appliance.
