Quafety scientists design a machinery for mechanical peeling and cutting of fresh-cut melons
The general aim of the work is improving efficacy and safety of fresh-cut melon and watermelon processing by substituting manual peeling and cutting operations by an automatic hands-off machine. The present study is designed to develop technology and machinery able to mechanically cut and peel melons and watermelons in order to prepare fresh-cut fruits.
Rodov says: "As part of this study we have examined several alternatives to perform the whole process, ranging from laser-cut to high-pressure water using artificial vision systems as utilized in sorting processes in the production industry. We have evaluated, analysed and developed a number of special puncturing tools: fixed, rotating, solid and perforated".
The efficacy of the technology was evaluated measuring the quality parameters of fresh-cut fruits during shelf-life. It was found that a round, disk shaped slice as a final product is achievable and maintains quality requirements for more than a week in a cooled and sealed plastic package.
The results of these trials have led to the design of the system performing peeling/cutting operations without a human hand touching the cut fruit. Rodov concludes: "At this stage the machine requires a manual feed of the raw fruit. The main parts of the machinery have been built and tested successfully".
