Bluezone Fresh Preservation Technology for Ethylene and Microbial Control in Refrigerated Containers
Primaira, LLC has developed and is testing a safe, low cost, low maintenance, plug-and-play solution to ethylene and microbial control. Bluezone Reaction Technology for refrigerated containers and coolers Removes ethylene from ambient air for shelf life extension Kills airborne molds, fungus and bacteria Eliminates odors and flavor transfer No impact on container No impact on available volume The technology to implement the science is novel, cost effective, and patented. System is easy to install. 2 Confidential Information
The Bluezone Fresh Preservation Technology offers multiple benefits in refrigerated shipping of FF&V. Extended shelf life Minimized waste Longer distance shipping of sensitive produce Reduced need for chemical solutions to combat decay Fresh preservation for Organics Optimized ventilation for CO 2 No ethylene build-up Transition from air to ocean transport 3 Confidential Information
We have designed a unit for installation in the locker next to the refrigeration unit: no loss of container space. 4 Confidential Information
The specifications of the Bluezone Locker Unit are shown below: Specification Value Dimensions: 6.6 X 12 X 48 Power Voltage Capacity Weight Expected steady state ethylene level <300 W 277V 40 Container 35 lbs. 0.05 0.5ppm The unit has passed military safety and durability tests, meeting strict US Navy requirements for installation in an aircraft carrier. 5 Confidential Information
Bluezone Reaction Technology removes ethylene and microbes from ambient air in a self-contained air cleaning unit. Air is drawn from the container into the Bluezone unit where contaminants are destroyed Ethylene destruction rate = ethylene generation rate Kills airborne molds, fungus and bacteria No safety issues, No ozone in container Purfresh adds ozone directly into container to reduce microbes. Produce is bathed in low level ozone at all times; can damage some produce and refrigeration equipment Minimal ethylene control Ozone attacks container seals and elastic materials in load. 6 Technology Comparison: Bluezone technology is not the same as Purfresh. Health/Safety concerns Confidential Information
Primaira uses state-of-the-art development and testing tools to ensure high product performance. Fruit quality measurement Gas Chromatograph to measure ethylene Ocean Trials 7 Impactor to measure microbial load in air. In-House Testing
The unit has excellent ethylene removal rates: pull down from 10 ppm to less than 0.5 in less than 3 hours. 8 Confidential Information
Additional testing shows that pull down rate is not affected by CO 2 concentration, temperature or humidity. 9 Confidential Information
Bluezone provides significant benefits to the shipping of the following fruits and vegetables: Kiwi high ethylene sensitivity- low threshold for response to ethylene. Extend shelf life Keep ethylene below level that induces ripening while optimizing CO 2 levels) Bananas- rapid ripening response from ethylene Extends shelf life; Prevents ethylene levels from rising to a level that will spring an entire load) Avocados, pears, stone fruit, mangoes high ethylene production rates and sensitivity. Extends shelf life Maintains quality Asparagus high ethylene sensitivity Extend shelf life by optimizing CO 2 without ethylene build-up Onions- susceptibility mold Melons high ethylene production and sensitivity; susceptibility to mold Grapes Ethylene impact on shatter Improves quality/reduces shatter Oranges Susceptibility to mold Improves quality/reduces mold 10 Berries Susceptibility to mold Confidential Information
Bluezone allows the ventilation rate to be set in a Kiwi load that optimizes CO 2 without ethylene build-up. Positive demonstrations in Chill Boxes in Australia. 11 Confidential Information
Bluezone can avoid ripening of Banana load during extended trips. 12 Confidential Information
Bluezone will extend asparagus shelf life by allowing the ventilation to be properly set without ethylene build-up. 13 Confidential Information
Bluezone cleans the air of mold. Bluezone On, +me = 0 Bluezone On, +me = 1 hr Bluezone Off, +me = 0 Bluezone Off, +me = 1 hr
The US Army funded the development of the Bluezone Fresh Preservation Technology to deliver the highest quality fruits and vegetables for our troops. Army-tested Military approved Award-winning Commercially available 15 Confidential Information
16 Bluezone Sea trials with table grapes were highly successful: shatter reduced compared to standard shipments.
17 Successful Bluezone trial with oranges: consignee stated improved freshness and brighter color compared to standard shipment.
