Atmospheric Plasma for Food Preservation

Introduction

Kerone’s Atmospheric Plasma Systems are engineered to extend shelf life and enhance food safety by inactivating surface-level microorganisms without altering the food’s natural properties. Unlike vacuum plasma systems, atmospheric plasma operates under normal pressure conditions, making it ideal for continuous food processing lines. The technology produces reactive species (ROS/RNS), UV photons, and ions that deactivate pathogens, delay spoilage, and reduce chemical preservatives in packaged and unpackaged foods.

Why Choose Kerone Atmospheric Plasma for Food Preservation

Kerone’s systems feature uniform plasma jets, dielectric barrier discharge units, and controlled exposure modules designed for surface sterilization of fruits, vegetables, meats, grains, ready-to-eat foods, and packaging materials. Atmospheric plasma ensures minimal thermal impact, low operational costs, and fast microbial inactivation.

Types and Features of Atmospheric Plasma for Food Preservation

Kerone’s Atmospheric Plasma Systems are developed in multiple configurations to support diverse food safety and shelf-life enhancement needs. Plasma jet systems deliver focused, high-reactivity plasma streams for precision treatment of irregular food surfaces such as fruits, vegetables, spices, and meat cuts. DBD (Dielectric Barrier Discharge) atmospheric plasma units generate uniform plasma across wide surfaces, making them ideal for flat or packaged foods requiring gentle, non-thermal microbial inactivation. Surface plasma treatment conveyors integrate atmospheric plasma modules directly onto processing lines, enabling continuous treatment of bulk foods, trays, and packaging films without disrupting workflow. For high-throughput facilities, plasma shelf-life enhancement tunnels provide controlled exposure zones with adjustable gas composition, power intensity, and exposure duration to ensure consistent spoilage reduction and microbial control across large batches. Each system is designed with food-safe materials, real-time plasma monitoring, temperature-safe operation, and PLC automation to deliver repeatable, eco-friendly, and residue-free food preservation.
