Initially focused on whole chickens, Bulgarian poultry processor Gradus now produces a wide range of cut chicken products, including breast fillets, wings, legs and giblets. In 2024, Gradus installed a complete, new JBT Marel secondary process including an ACM-NT cut-up line and two AMF-i breast deboning systems. Martin Dimitrov, CEO of Gradus-1 (Gradus AD’s processing subsidiary), talks about the trends in Bulgarian poultry consumption, which led to the company’s changes.

In Bulgaria, two key trends define the meat market: increasing per-capita meat consumption and a shift from red to white meat.

Shifting sales channels

Martin Dimitrov explains, “In Bulgaria, chicken sales have shifted away from small shops and distributors. Supermarkets now account for the largest share. At Gradus, we have moved along with this trend. Right across Bulgaria, the brand Gradus has a recognition level of 98%, which is close to Coca-Cola.”

A trend toward chicken pieces

Initially focused on whole chickens, the company now produces a wide range of cut chicken products, including breast fillets, wings, legs and giblets, mostly under the Gradus brand. “Whole chickens, frozen but also fresh, remain important, but we see a steady rise in demand for fresh chicken parts, especially fillets,” says Martin Dimitrov. “We believe this trend will continue, and at Gradus, we are adapting to meet this demand from the market. Our goal is to shift our production ratio from the current 30/70% split between whole chickens and cut-up parts to 10/90%.

Modernization

In 2024, Gradus installed a new secondary process including an ACM-NT cut-up line and two AMF-i filleting systems. “This was necessary to keep up with the primary process. Our filleting capacity with off-line trimming was simply too low.” Gradus upgraded in partnership with JBT Marel. “JBT Marel really helped us enhance our efficiency and product quality,” notes Martin Dimitrov. The 2024 upgrade to the processing facility in Stara Zagora, built in 2007 as a fully Stork-equipped 8,000 bph [133 bpm] greenfield, has doubled Gradus’ capacity for cut-up and filleting.

Smooth product flow

In the new distribution line, chilled products are weighed and quality graded by JBT Marel’s SmartWeigher and IRIS systems. With their data, it is decided for each product whether it is to be cut up or graded and packed as a whole bird. Products selected for cut-up enter the ACM-NT line. The smooth product flow prevents congestion and disruption, ensuring continuous, inline processing. Products remain in their shackles throughout, simplifying logistics and significantly reducing manual labor.
Legs and wings go their own way to packing, while breast caps enter the AMF-i breast cap filleting systems, ending up as deboned breast fillets and tenderloins.

Higher volume, higher quality

“The goal of the upgrade was to improve efficiency, reduce labor, increase yield and volumes in the secondary process and to match the capacity to our primary process. That has worked out very well. As a result, we have even more operators on the line now, but with much higher meat production per man-hour. Their roles have changed from physical stress and intensive trimming to a more streamlined and effective operation,“ explains Martin Dimitrov. “The new JBT Marel systems are not only faster but also drastically improve the quality of our fillets and tenderloins. The smart design also reduces manual handling, which is better for our employees, and produces fresher, higher-quality products with longer shelf life for our customers.”

The new JBT Marel systems are not only faster but also drastically improve the quality of our fillets and tenderloins.

A common goal

Installation of the update went very smoothly. Extensive preparation by the JBT Marel and Gradus teams prevented unexpected surprises and ensured successful implementation. “The JBT Marel team showed professionalism, reliability, and high technological knowledge. Communication was pleasant on technical and personal levels. We had some challenges. Such issues are, however, expected with new systems and were managed effectively. That’s because everyone shared a common goal, which was the optimization of Gradus-1 to meet market needs,” confirms Martin Dimitrov.
