According to the USDA Foreign Agricultural Service, Canada is the fifth largest exporter of processed food and beverage products in the world. Our sophisticated processing sector is supported by over seven thousand facilities across Canada. Every single one of these establishments must meet the high standards set forth by the Canadian Food Inspection Agency. Mechanical insulation is one important piece of the overall puzzle. This week, we are going to look at how the appropriate insulation can improve food safety and improve industry processes.
Fibrous, Porous, and Wet
Food processing is a unique sector in that it requires machines and systems to work with fibrous, porous, and even wet materials. Without the proper considerations, this would create the perfect environment for equipment breakdown, mould growth, and bacterial spread. Furthermore, processes such as meat cooking and pasteurization are both examples of high heat applications used over a long period of time. As we’ve mentioned before, extreme temperatures add moisture into the air, which condenses on cold surfaces.
High Cleanliness Standards
In conjunction with the often messy nature of food processing, regular deep cleanings must be done to ensure the health and safety of the workspace, workers, and products. Regular cleaning, sanitizing, and sterilizing are all separate and important steps designed to achieve these ends. This will include the use of water, chemicals, and even physical scrubbing on all surfaces that are to come into contact with food materials.
Common Insulation Materials
All these considerations require specialized attention when it comes to designing an effective insulation system. Insulation materials must be non-toxic, odourless, and non-contaminating to even be considered in this type of application. Beyond this, professionals will always opt for closed-cell materials. Closed-cells act as extremely effective moisture barriers, reducing vapour’s ability to penetrate through walls or equipment. Materials that could be used are cellular glass, flexible elastomeric, and polystyrene. In addition, all insulation materials must be covered with PVC or metal jacketing. This is to further combat moisture as well as resistance from the physical impacts of repetitive cleaning.
Food safety is a directive that involves several parts to be effective. Mechanical insulation in food processing facilities works in tandem with policies and procedures to ensure optimal health, safety, and efficiency.
