Cold Plasma for Food Sterilisation 

Kerone’s Cold Plasma Food Sterilisation Systems are engineered in multiple configurations to meet the diverse processing needs of fresh, packaged, and high-value food products. In-package cold plasma systems generate reactive plasma inside sealed containers or pouches, achieving sterilisation without exposing food to external contamination—ideal for ready-to-eat meals, deli cuts, and minimally processed foods. Conveyor-based cold plasma tunnels enable high-throughput, inline treatment of fresh produce, meats, bakery goods, and dairy surfaces with uniform plasma exposure and adjustable belt speed for precise microbial reduction. Plasma jet and DBD (Dielectric Barrier Discharge) systems provide targeted or wide-area non-thermal sterilisation, delivering reactive species directly onto complex or uneven food surfaces while preserving appearance, flavour, and nutrients. All systems are equipped with gas-modulated plasma generation, humidity control, PLC automation, and food-safe construction to ensure repeatable, chemical-free microbial inactivation that maintains fresh-like quality.
