Maintain quality and freshness of cherries while increasing returns

Food-safety concerns, environmental discharge regulations, increasing wastewater disposal costs and a move to reduce chemical usage, have driven increased demand for proven, environmentally friendly, ozone-based solutions for the disinfection of fresh produce. Purfresh’s wash solution provides packers and processors a cost effective way to enhance food safety, improve fruit quality, and provide documented evidence for regulatory and food safety bodies while reducing or eliminating the use of chemicals.

SCIENCE BASED SOLUTION
Purfresh’s science-based ozone solution efficiently dissolves ozone into process water at precise concentrations for use as a safe but powerful disinfectant in hydrocoolers and spray bars for cherries. The solution kills pathogens and controls cross-contamination of a broad spectrum of food- and water-borne microorganisms. Incorporating ozone into the rinse process, growers and processors can control ORP levels, enhance food safety practices and reduce the use of chemicals.

OPTIMUM SAFETY AND EFFICACY
Purfresh’s unique closed-loop concentration control and remote monitoring capabilities provide optimum safety, efficacy, and informatics. Its measurement sensors and on-board computer maintains ozone concentrations to a desired setpoint. This dissolved ozone setpoint is adjustable by the user. This allows a user to customize the use of the system to meet their needs. ORP monitoring also allows a referencing of DO3 concentration to when known ORP levels. The solution includes fail-safe ambient air sensors, which constantly ensure work areas maintain ozone concentrations well within OSHA standards. Its remote monitoring service constantly tracks system performance and provides detailed reports and automated alerts.
