Poultry processor goes for weighing technology from MULTIPOND

The long-established poultry-breeding KG Group is one of Lithuania's highest-tech and economically strong production associations in Lithuania. The Vilnius-based company follows a philosophy of tradition, perfected experience, high working standards, as well as quality and modernity in production technology. The meat is supplied exclusively from its own poultry farms. Over 9,000 tons of meat are packaged every month, around half of which is exported abroad.

The company's huge success and the continuous growth this generates means the company group now has to be expanded. Just recently, production was extended into another area with three new packaging lines. As far as multihead weighers are concerned, numerous tests were conducted with various manufacturers. The test results clearly argue for MULTIPOND. As the only manufacturer of multihead weighers, MULTIPOND was also able to meet the requirement of weighing both fresh marinated and deep-frozen products by a fully-automated process using just one system.

For good reason, then, Valdas Keršys, Maintenance Manager, decided on MULTIPOND for the multihead weighers. Just recently, two type MP-14-7100-2500-H-UL systems and a type MP-14-3800-2500-H-UL weigher were purchased for the factory in Vilnius for the fully-automated weighing of various poultry products.

The project is unique in that each line has been converted with a different packaging machine to be able to fill the most diverse types of packaging.

The poultry products are fed to the three weighing systems via special spiked conveyors from the French company MCA. Once on the weigher, the poultry meat is first conveyed to the prefeed hoppers via the radially positioned feed trays and then to the weigh hoppers below. Another key purchase criterion for the KG Group was the use of the patented surface profile on the distribution cone and feed trays.   

This effective yet simple solution permits a straightforward and controlled conveying of the most adherent products, while maximizing careful product handling.

Using the partial portions, a computer determines the combination that comes closest to the target weight. The fully automated calibration of the proprietary load cells ensures the highest accuracy and availability by means of calibration weight. As Valdas Keršys, Maintenance Manager explains, "The accuracies are incredible, the investment has paid off in a very short time. The fully-automated calibration was another major advantage in our purchasing decision." The mean value, the critical value for the calculation of the giveaway, is less than 1% of the target weight.

After the actual weighing process, the accurately weighed portions are transferred to the product transfer system designed specifically for this application. This is the interface between weigher and packaging machine. A form fill seal machine, tray line and a thermoforming machine are fed without any problem.

With target weights of 250g to 5000g, the outputs here are up to 80 weighings per minute for deep-frozen goods and up to 42 weighings per minute for fresh poultry.

Since the KG Group requires frequent product changes, up to 38 different products are run on one system, a key purchase criterion for Valdas Keršys was the quick and tool-free removal of product contact parts, which effectively reduces the systems' standstill time for cleaning and maintenance work to a minimum. Wash racks, which simplify the cleaning process many times over, have been mounted on each platform.

"The short routes and instances of MULTIPOND were extremely advantageous for the project implementation. Drawing on its long-standing experience in weighing the most difficult products, the company was able to offer advice and support. All MULTIPOND systems have run smoothly since installation and are completely reliable," says Keršys.
