Anjari, Chile

The Anjari family business, located in San Esteban (Chile), one of the main fruit-growing areas of the country, exports its products to five continents. Founded in 1990, it pioneered the drying of raisins and now produces 16,000 tons a year. The business’s growth and demand for product quality have led to the acquisition of TOMRA’s Helius 1600 free-fall sorter, which guarantees the selection of defect-free products and has the highest processing capacity in the raisin manufacturing industry.

Chile is the sixth largest raisin producer worldwide, the fifth largest in terms of harvest, and the fourth largest exporter. Chilean raisins come from discarded grapes that do not meet quality standards for fresh fruit exports and are known internationally for their high quality, excellent flavor and unique size.

Anjari already operates two TOMRA Ixus detectors (models 570 and 800), purchased in 2006 and 2015 respectively, which use X-ray technology to detect and eliminate foreign materials (metals, glass, stones, high-density plastics, etc.) from the product. The decision to purchase the Helius 1600 was based on experience and knowledge of the advantages of TOMRA technology.

Carlos Correa, Sales Agent for TOMRA Food and Sales Manager for SASA, a company which supplies technology solutions to the Chilean food industry, says: “Anjari is a family business that stands out for its owner’s drive and initiative and for taking a more broad-minded approach to the importance of technology in enhancing its processes and products. They needed to boost their production capacity and detect foreign materials more efficiently during the process. TOMRA combines laser and X-ray technology to detect tiny foreign materials, guaranteeing food hygiene and safety in processed foods.”

“TOMRA’s equipment plays a fundamental role in the production lines, controlling important factors such as flow, yield and defects, without comprising the end quality of the products that customers have come to expect. All of our machines work together, and because they each have different detection sensitivities, they cover a much broader scope in picking out foreign material from the product. TOMRA technology has allowed us to penetrate much more discerning markets, and to build and sustain a prestigious name for ourselves, and for our final products”, says René Anjari, Anjari's owner and founder.


Anjari uses the Thompson grape variety, which is elongated and slightly bittersweet, and the Flame variety, which is round and very sweet and is the grape that gives Chile its popularity in the raisin sector.

At Anjari’s plant the process starts with the fruit dried and stored in wooden bins in the selection and packaging line, depending on what was requested in the production programme. The fruit is then submerged in two washtubs containing tepid water and pumped towards a cascade-based destoner, after which the raisins enter a centrifugal dryer. The raisins are nebulized using a peracetic acid-based solution (sanitizing) and go through a vibrating sifter to the first TOMRA detector equipped with multiple lasers: the Helius 1600. This machine offers different programs according to the type of raisin being packaged and eliminates any foreign material, based on color and structure differences.

The raisins then go through the second detector, this time X-ray, the Ixus 800, which removes the foreign material by detecting density differences in the contaminants. Afterwards the raisins are distributed onto three conveyor belts for manual inspection, where highly-trained Anjari employees visually check the raisins to ensure no non-raisin matter remains in the product. At this point a belt collects the raisins selected from the manual inspection belts and these are taken to a third detector, which again detects and removes foreign material based on color differences. Finally, the raisins go to the fourth x-ray detector, the Ixus 570, which detects differences in density and again removes any remaining foreign material. For the final check, the raisins, now packaged and the boxes sealed, go through two metal detectors.


“Every stage of our production chain involves the strictest quality controls. We use detectors in the packaging line that other local plants do not have and every year we invest a huge amount in infrastructure to guarantee the quality of our products. Thanks to the installation of the new sorter, we have been able to increase production yields and reduce waste, as it is very accurate. The Ixus is a very useful tool to eliminate elements of a different density to raisins and is highly effective with stones of various sizes”, says Anjari.

The Helius 1600 ensures the final product has excellent quality, without unwanted discolorations or foreign materials. Its ejector valves reject defects in milliseconds; its small system barely takes up space; quality control and information can be accessed through an intuitive touch screen; it has a modular and upgradeable design which provides different types of laser technologies adaptable to the application; and it can be synchronized between low and high capacities. The Helius 1600 also has an effective expulsion system for constant accuracy and very low false rejection rates. In addition, this machine has a high capacity of 8 to 10 tons per hour and a long service life.“The advantage of the Helius 1600 is that it allows us to tailor the detection programs to our needs. Because of its high sensitivity we have been able to increase yield without changing the quality of the end product,” says René Anjari.

“Anjari would recommend TOMRA to any companies that want to ensure quality without sacrificing productivity.”

Carlos Correa adds: “TOMRA stands out for its high-tech machines and excellent customer service, always on hand to help with operating, updating and maintaining the equipment.”
