January 14, 2020 – Antarctic Foods takes product quality seriously. Selling frozen vegetables to baby food processors and others throughout Europe, Antarctic has grown 25 percent annually over the last few years. As they expand, they’ve turned to Key Technology. In 2017, they installed Key’s most advanced digital sorter, VERYX®, to remove foreign material (FM) and defects from product prior to blanching. In 2019, they added another VERYX immediately prior to packaging. Now, with two VERYX sorters on one production line, Antarctic is maximizing efficiency and elevating food safety.
“Before we chose VERYX, we considered others. The very positive experiences I had with Key and their equipment when I was at Pinguin influenced our decision. Plus, the fact that VERYX is the latest technology – that’s what we want in our factory,” said Herwig Dejonghe, Director General at Antarctic. “Because we sell our frozen vegetables as ingredients to other food processors, many of our customers also use digital sorters, so they know the technology. Having two VERYX sorters on one line differentiates us. We’re demonstrating our commitment to producing top quality product.”
Antarctic selected a belt-fed VERYX B140 sorter on the wet-end of their processing line, where product is a bit sticky. They chose a chute-fed VERYX C140 for final inspection, where frozen product easily slides down the chute. “Product handling is extremely important to achieving the best sort accuracy,” noted Dejonghe. “That’s why both of our VERYX sorters are integrated with Key’s Iso-Flo® vibratory infeed conveyors, which have been customized specifically for our products.” This line prepares carrots, green beans and salsify of different types and various cut shapes and sizes.
VERYX is ideal for processors, such as Antarctic, that handle multiple seasonal products. The sorter’s unique recipe-driven operation allows it to be changed over to handle a new product in seconds with only a couple of taps on the touchscreen. “Saving sort recipes to VERYX’s memory eases use and helps us produce consistent results,” said Dejonghe.
“On the wet end, the primary objective of the sorter is to remove foreign material and defects before we consume the energy to blanch and freeze. Also, our belt-fed VERYX features three-way sorting, so in addition to having one reject stream that leads to waste and one accept stream that leads to the freezer, we also have a third stream for product that’s below grade or needs rework. By separating this third stream prior to blanching, it has more value because we can do more with raw product,” explained Dejonghe. “Of course, the primary objective of sorting frozen product immediately prior to packaging is to ensure final product quality.”
To maximize food safety, Antarctic selected two fully-loaded VERYX sorters. Their belt-fed B140 features top- and bottom-mounted off-axis cameras as well as two-sided laser sensors and Pixel Fusion™ to achieve all-sided surface inspection. As the world’s only belt-fed sorter that inspects product entirely in-air with top and bottom sensors, VERYX is able to see more FM and defects. The bottom-mounted sensors, in addition to light sources and backgrounds, are positioned away from product splatter so all-sided surface inspection is sustained throughout long production cycles without operator intervention. Similarly, Antarctic’s chute-fed C140 features front- and rear-mounted cameras and laser sensors as well as double-sided Pixel Fusion.
With next-generation 4-channel cameras, VERYX recognizes colors, sizes and shapes. With high-resolution laser sensors, VERYX detects structural properties, including the presence of chlorophyll. Key’s unique Pixel Fusion detection module combines pixel-level input from cameras and laser sensors, producing higher contrasts to find the most difficult-to-detect FM and defects without false rejects. These sorters remove foreign material such as insects, animal parts, paperboard, wood, rocks, plastics and glass as well as extraneous vegetative matter (EVM) such as weeds from the product stream. They also find and remove product defects to make grade.
“Weeds like nightshade and datura are a much bigger problem than they used to be. With farmers using fewer pesticides and herbicides on conventional crops and, of course, the enormous growth of organic farming, we see a lot more weeds coming into our factory with raw product,” said Dejonghe. “We work hard to be sure we get all the EVM out. We use mechanical systems to remove as much as we can, and then we rely on our optical sorters to remove what the mechanical systems miss.”
“Since we installed our VERYX sorters, we’ve seen a big improvement. We measure the good-to-bad ratio and the defect removal rate in addition to tracking customer complaints,” concluded Dejonghe. “These sorters enable us to achieve our quality objectives virtually regardless of the quality of the incoming material. That level of quality control – that improvement in quality – would be impossible without this technology.”
