Is it possible for an automated system to run so efficiently you forget it’s there?

18 February 2018

Djurdjevic is a meat production company based in Serbia. To achieve its goal of offering high quality meat products to its local community the company has developed a state-of-the-art facility that  is able to handle all aspects of meat processing and production. Quality and safety are some of its priorities. 

To ensure the quality of its products, Djurdjevic often relies on automated machinery, which offers precise and consistent results. One of these machines is the factory’s biomass boiler. Steam is used in a wide variety of meat processing and treatment application, so this boiler is a key component of the factory.

The boiler is controlled by a Unitronics UniStream PLC with 10.4-inch touchscreen HMI. This PLC regulates and monitors the production of steam, managing the boiler heat and maintaining its runtime.

The PLC uses Canbus communication to communicate to remote I/O, including thermocouple inputs. Additionally, the Unistream PLC features many other communication options, meaning that it interfaces easily with other non-Unitronics devices, making monitoring easy. Djurdjevic also installed Jazz controllers at several other points in production for temperature monitoring.

Djurdjevic was very impressed with the UniStream; the PLC worked perfectly from when it was first installed. The application development was also very quick – using the all-in-one programming software and the built in image library helped Djurdjavic design easy to read, professional HMI screens.

Ðorde Kuzminac, factory CFO, explains: “For me, most important is that I forgot that it is there – and it does its job, a very important job, controlling steam production for our factory.”
