Leading citrus producer and exporter Sunriver Citrus has significantly increased sorting efficiency and capacity, minimizing downtime and manual sorting, to meet growing demand while maintaining the highest quality standards with TOMRA 5S Advanced sorters and the new Dynamic Lane Balancer. With TOMRA’s sorting solutions, Sunriver Citrus resolved light blemish issues and increased daily packing volume by 10%. The consistently good quality grading resulted in increased returns for the company and greater recognition for the Sunriver brand in the international markets.
Leuven, Belgium, 24 October 2024 – Sunriver Citrus is a leading citrus producer and exporter based in the Sundays River Valley in South Africa. It grows mandarins, clementines, lemons, Valencia oranges and navel oranges on its farms in Kirkwood, Sunland and Addo. The company takes pride in farming, harvesting and packaging all its fruit, which it sells on the domestic and export markets in North America, Europe, Asia, and Southern Africa. Since 1937, it has built a reputation for excellent quality, and is accredited and associated with strategic distribution and quality assurance partners around the world, such as Costco Wholesale, the BRCGS Global Standard for Food Safety, SIZA social compliance, and South Africa’s Official Perishable Produce Export Certification Agency.
Sunriver Citrus currently processes around 84,000 tons annually in its three packhouses. It has experienced fast growth in the past 7 years and expects this trend to continue. In 2018, it introduced the first TOMRA 5S Advanced sorter: “We had a lot of growth, and we needed sorters that deliver consistent grading to supply a perfect product,” explains Theunis Bester, Production Manager at Surinver Citrus. “Our vision is that in years to come there will be a high demand for citrus, but we at Sunriver want to be leaders in supplying good quality.”
The TOMRA 5S Advanced sorter impressed Theunis Bester with its performance: “We used to have issues with light blemish sorting before we installed the TOMRA sorter, now we don’t battle it anymore. We are packing better quality fruit because of the consistent good grading, and this good quality helped build our brand in the markets.” Motivated by the results achieved, Sunriver Citrus replaced sorters in the other two packhouses with a second TOMRA 5S Advanced in 2023 and, in 2024, a third one equipped with the new Dynamic Lane Balancer. “I think TOMRA have the best sorter in the world, and their technicians are always there to assist us. I didn’t even ask for quotes on other sorters for the last two projects,” says Theunis Bester.
Sunriver Citrus is now operating a TOMRA 5S Advanced sorter in each of its three packhouses to Theunis Bester’s great satisfaction: “TOMRA has certainly increased our sorting efficiency. The sorters have had no mechanical problems and reduced a lot of downtime and sorting labor – and with the performance they deliver, we need almost no manual sorting. TOMRA has increased our returns based on the good quality grading, and there is a demand for our Sunriver brand across the world.”
Unrivaled accuracy, high throughput, consistently high-quality grading
TOMRA Food’s partner in South Africa, Masgcor, advised Sunriver Citrus and installed the lines in its three packhouses: “Each packhouse has a Masgcor citrus processing and packing line where the TOMRA sorters form the main electronic sorting platform in a commit-to-pack layout,” explains Gerhard Verster, General Manager at Masgcor.
The TOMRA 5S Advanced sorter builds on the class-leading performance of the Compac Multi-Lane Sorter to deliver unrivaled accuracy and the industry’s gentlest fruit handling. Its specialized software features programs for element mixing, exact packout optimization, and throughput control, providing high efficiency across the line. “The TOMRA 5S Advanced stands out for its reliability and accuracy. It can handle superior volumes and delivers consistent superior quality to consumers,” says Gerhard Verster. The sorters’ ability to optimize packout is instrumental in Sunriver Citrus’s success in the international markets: “We have the right quality in the cartons for the right markets,” explains Theunis Bester.
Maximum cup fill across lanes for high throughput and packout results
Sunriver Citrus prides itself on innovation – for example, it was the first company in South Africa to use skid steer loaders in the fruit picking process. Its innovative nature came to the fore when equipping the third packhouse, opting for a TOMRA 5S Advanced with a Dynamic Lane Balancer – the first to be installed in the country. “The first reason for installing it was to address space limitations in our new packhouse, and to push the volumes through without having bottlenecks at the sorter by ensuring even spreads on the lanes,” says Theunis Bester.
The Dynamic Lane Balancer automatically optimizes the flow of fruit on the sorter to ensure an equal distribution across all lanes. It constantly makes automatic adjustments based on data from its interface with the sizer software. “There is less than 5% difference in cup fill between different lanes, which means more effective and superior throughputs,” explains Gerhard Verster. “We have a more even spread on sizer lanes, and this enables us to push more volumes. We achieve 10% more volume on packing per day, and the sorter can run slower because of the good spread on the lanes,” concludes Theunis Bester. As a result of this performance, Sunriver Citrus is planning to install Dynamic Lane Balancers in its other packhouses.
