Effets et conditions de la ventilation pour le transport en conteneurs frigorifiques.

Ventilation effects and requirements in containerised refrigerated transport.

Auteurs : HEAP R., MARSHALL R.

Résumé

Fresh fruits and vegetables are alive and require fresh air to allow respiration. Without ventilation during transport, respiratory gases can build up and damage the produce. Historically, high ventilation rates have been used, which impact unfavourably on temperature control, humidity, and energy use. Calculation programmes are now available which allow easy calculation of ventilation requirements in containerised transport for given upper levels of carbon dioxide or ethylene. These programmes are described and are used to compare necessary ventilation rates with those generally used in transport. It is shown that, for produce with low rates of respiration, ventilation rates are generally appreciably higher than necessary.
