GEA has supplied integrated cooling and heating systems for the new site of the poultry processing company 2 Sisters Storteboom in Komorniki, Poland. Both companies have worked closely in the planning, configuration and installation of these systems. The aim was to reduce energy consumption and CO2 emissions, thus protecting the environment and saving costs.
With this joint project, the two companies built on a continuing partnership that began in 2007 with the opening of the site in Kotowo, also in Poland.
Innovative cooling system
Chicken products require low temperatures for optimum safety and quality, for example to prevent the growth of pathogenic bacteria such as salmonella. The cooling system installed in Komorniki helps to maintain optimum conditions for processing and storage of chicken products – a temperature of zero to 2-degree Celsius in the production rooms, around 7-degree Celsius in the auxiliary rooms, and -40-degree Celsius in the spiral freezer and blast freezer.
Ventilation and heating
Poorly maintained building ventilation can increase the spread of some bacteria and viruses. Therefore, a well-designed ventilation system in a chicken processing plant is of utmost importance.
GEA has designed a ventilation system for the whole building, tailored to the specific requirements of the different rooms. In addition, GEA’s analysis of the heating process revealed that it could allow 2 Sisters Storteboom to reduce fuel consumption and increase energy efficiency through the installation of GEA heat pump technology. The system recovers waste heat from the cooling system to heat water to 55oC, which is then used to wash the plant.
Low energy consumption and carbon footprint
The integrated configuration of cooling, ventilation and heating systems is said to be energy efficient and sustainable, as Johan Nap, who is responsible for the operations at 2 Sisters Storteboom in Poland, claimed: “GEA’s solutions fit very well with 2 Sisters Storteboom’s commitment to the environmental protection.”
The cooling system uses ammonia as a natural refrigerant. The compressors and main units are equipped with frequency inverters to ensure efficiency of the entire installation. The heat recovery system replaces the gas-based boiler heating system, thus reducing CO2 emissions.
