Perishables are defined as goods that have a short shelf life. Since they spoil quickly, we are often forced to dump such products before we consume them. When food insecurities are growing every day in different parts of the globe, preserving and improving such perishable foods’ shelf-life becomes necessary.
Cold Storage Containers
Cold shipping containers are an excellent solution for storing perishables. These products would be mostly held in 20′ or 40′ trailers, almost like on-site walk-in refrigerators and freezers. They are also called reefer containers and can be transported by rail or road. They come with some advantages.
- Convenience for large sporting events or weddings or restaurants.
- Consistent climate-controlled environment.
- Optional built-in lighting and shelving help in organizing the stored items
- Electric-powered unit designs are suited for maximum thermal efficiency and minimal air leakage.
Another option for storing perishables is dry ice, which is a way to keep your frozen and refrigerated foods from spoiling if there are chances of power cuts or travel. Dry ice is maintained at a temperature of -109 degrees Fahrenheit and can easily replace a refrigerator or freezer. The procedure is easy and hassle-free. Place the dry ice on the top shelf of the freezer and the bottom shelf of the fridge. In case you are evacuating or moving, perishables can be transported using dry ice placed in a cooler. People prefer dry ice for the following.
When mechanical refrigeration is not viable, dry ice can be used in food storage and transport. A benefit of using dry ice over ice is that the problems associated with water leakage are non-existent since dry ice evaporates into a gas and allows the container to be free of moisture even after several hours.
However, there are some precautions to be followed while using dry ice.
- Always wear gloves and long sleeves while handling dry ice.
- In case you are traveling, do not carry a cooler with dry ice in an enclosed passenger cabin to avoid any issues with carbon dioxide build-up.
Choosing between storage containers and dry ice for perishables largely depends on the different conditions, like the scale of storage, transportation, or storage period. It is always advisable to consider these aspects before making your selection.
