Efficient energy systems for the dry-cured meat industry.
Number: pap. n. 0036
Author(s) : KVALSVIK K. H.
Summary
Eight energy systems for dry-cured meat drying were modelled and simulated in Dymola and their energy consumptions compared. The systems included heat pumps, electrical heat, air compression and adsorption. All but an adsorption system were satisfactorily modelled, and a system using CO2, with an additional heat exchanger and controlled to dehumidify as little of the air as possible, showed the best performance. A similar ammonia system was the second best if excess heat could be utilized, using 8.9 MWh against 5.3 MWh in the simulation. Drying efficiencies up to 190 % were found. Utilization of excess heat and minimizing the fraction of air for dehumidification had large impacts.
