    Like many other fruits, table grapes depend on accurate temperature management during transport in maritime refrigerated containers. Ideally the temperature inside the container is equal to set point in every location in the container. Unfortunately door-end temperatures are always higher due to poor air flow distribution. In climate chamber tests Lukasse & Staal (2016a and 2016b) investigated the effect of covering sections of the container’s T-bar floor. The best T-bar floor cover found in that study was a trapezoid-shape floor cover. The aim of this study is to assess the effect of that trapezoid-shape T-bar floor cover on temperature and fruit quality in commercial reefer container transports of grapes. A field experiment was done in a commercial container shipment of six standard 40 ft. HC reefer containers travelling from South Africa to The Netherlands taking 24 days. The three test containers contained a T-bar floor cover. The three reference containers did not contain the T-bar floor cover. All other parameters were, to the extent possible, the same for all containers. In 31 locations air temperature between the fruit was logged at an interval of 10 min. with an accuracy of approx. ± 0.1 °C. 15 Trays, evenly distributed in a vertical plane on the container’s longitudinal centre line, were weighed at origin and at destination. At destination the fruit quality of these 15 trays was analysed. A clear positive effect on temperature was observed. The floor cover reduces the average difference between warmest and coldest temperature in the trays by approx. 30%. An effect on grape quality could not be assessed.

    Explanatory notes to the ATO-certification of reefer containers (version 4.0)

    Intercontinental transport of flowerbulbs in general takes place in climate controlled seagoing reefer containers. A shipment may take two up to six weeks. To maintain quality during this time span proper climate inside the container is important. ATO certification yields a quality assurance on aspects not covered in other standards or certification schemes, and primarily of interest to flowerbulb shipments.
    Quest II: reduction of co2 emissions of reefer containers

    This paper reports on the QuestTM II (QUality and Energy in Storage and Transport) development project run by Wageningen UR Food & Biobased Research, Maersk Line and Carrier Transicold. The aim of the Quest II development project was to improve the control of refrigerated marine container (reefer) units with the objective of maximizing energy efficiency in chilled mode operation without impairing produce quality. Lab testing research on produce quality revealed the limits by which deviations from the optimal transport temperatures are acceptable. Those limits were used in the design of the Quest II algorithm. Quest II control reduces energy consumption in chilled mode operation by 65% compared to non-Quest control. The savings are achieved by replacing continuous throttled compressor operation by an ON/OFF compressor control, and by automatically optimizing internal air circulation with heat load instead of continuous operation at maximum internal air circulation. Extensive produce quality research and hundreds of field trials reveal no adverse effect on produce quality while using the Quest II algorithm.

    Tientallen miljoenen per jaar bespaart de mondiale scheepvaart dankzij onderzoek van Food and Biobased Research. Programmacoördinator Toine Timmermans is er zichtbaar trots op. Onderzoek dat in de jaren negentig begon, zorgt ervoor dat de grote meerderheid van de koelcontainers op schepen nu minstens vijftig procent minder energie gebruikt.

    Ethiopia has a big potential to grow more fruits and vegetables. Ethiopia’s current fruit and vegetable export is very limited. Scope for expanding and diversifying its export markets is large. Demand for fruits and vegetables is growing in nearby international markets, like the Middle East. Although Ethiopia is land locked, it is geographically close to the Middle East. To reach the Middle East, and other international markets, produce has to be transported to Djibouti where it can be shipped. Roads to Djibouti are generally good, but transportation takes long due to long waiting times at the border, sometimes up to ten hours. Fresh produce is sensitive and needs to be refrigerated to remain fresh and of good quality during such long transportation time. To start exporting to the Middle East it is of paramount importance to build a good reputation and to deliver the fruit and vegetables in good condition. Refrigerated container transport offers possibilities to make use of the potential to export more fruit and vegetables which arrive the market in good quality. This report offers an overview of the feasibility to use refrigerated container transport for Ethiopian fruit and vegetables export to the Middle East

    In this paper a concept for energy saving for refrigerated container transport is presented. The concept is based on model-predictive control of the set points of the cooling unit. These models predict energy consumption of the cooling unit, climatic conditions inside the cargo space, and the change in product quality. The objective of the control is to minimize energy consumption while retaining a certain level of product quality. After presenting the concept of the model-predictive control the predictive power of the models used are shown. These models show that we are able to predict energy consumption, temperature, humidity and gas conditions quite accurately. Furthermore, an indication is given for the quality change model to be employed. The impact of the novel control is shown by simulation of a transport of apples
