Because the U. Knocking down spoilage organisms and bacteria is essential if fish is to have a realistic shelf life. While U. The first Canadian seafood processor to do so was Albion Fisheries Ltd. Ozonated water is applied to fish at Albion Fisheries prior to packaging and frozen distribution. Albion used a portable ozone generator to create sanitizing water for cleaning equipment and food-contact surfaces in its old processing plant in British Columbia. Managers wanted to include a centralized system for direct contact when they built a 70,sq.

Worker safety issues and unreliable controls that produced spotty results plagued ozone applications throughout North America in years past, giving ozone a black eye with many food companies. Health Canada gave its blessing in time for the December opening of Albion's new plant, where ozone-resistant piping delivers treated water to 20 rooms used for processing, receiving, storage and other operations.

After nine months of use, the concern is gone. Disinfection of open surfaces like conveyor belts are a perfect application for ozone. This guarantees high durability, especially for fresh produce in for example juice production. Many food processing facilities are dependent on cooling loops and towers for low temperature storage or temperature control of purified water PW used in production.

Ice water based cooling systems are prone to microbial growth which clog filters and enhances the risk of legionella outbreaks and general non-hygienic conditions. Ozone technology provides a very efficient way of ridding the system from all potential growth of bacteria and mold. It provides a microbe free environment at with the following benefits:. Ozonetech possesses experience and deep knowledge in the field of cooling systems.

Please go to this section for more information. Ozone has an inherently high oxidation potential, in other words, it has a high ability of oxidizing compounds it comes in direct contact with. It generates a series of chemical pathways upon reaction with organic compounds, producing radicals which display an even high oxidation potential compared to ozone itself. This provides very high disinfection capability and complements traditional chemicals when it comes to breaking down residues of fat, proteins and corbo hydrates. Ozone cannot be stored which is one of its main application benefits.

Advantages of Using Ozone

It eliminates the need to store and handle chemicals that are traditionally used for disinfection and cuts the costs for consumables. Ozone is produced from oxygen by exposing a gas feed to a voltage field, called Corona Discharge technology. High concentration ozone is produced by Ozonetech's water cooled and stable system with low power consumption.

Compared to other cleaning and disinfection agents, ozone holds many advantages which are outlined in the table below:. For closed process equipment in the food and beverage industry, ozone completely eliminates the need for traditional, organic and chlorine based disinfectants. This reduces the consumables cost and handling. It also makes typical CIP cycles more effective:. Ozonetech improves profitability and production efficiency by cutting Clean-in-Place cycle times by utilizing a more effective and environmentally friendly method of sanitizing tanks, pipes and other process equipment.

Since ozone does not leave any harmful by-products, ozonated disinfection water can be reused for other CIP phases, such as pre-rinse. In this respect, ozone disinfection can reduce the water consumption of the whole CIP process. Reduced water consumption means less load on wastewater treatment plants.

Thanks to the benefits of cold water disinfection, large amounts of energy can be saved, which would otherwize be used to for hot water or vapor. This makes ozone a smart choice both in terms of operational costs and the environment. For disinfection, ozone completely eliminates the need for traditional chemical dosing, which lowers the chemical costs. It may be used in combination with cleaning agents to enhance the cleaning efficiency, thereby further reducing the amount of cleaning agents or required water temperatures.
