Rather than blasting cold air at food product and hoping some airflow gets to the center of the pallet stacks, QuickFreeze uses patented technology to pull air through the product for fast, consistent and predictable freezing, says the company. Airflow is the most important factor in removing heat during the freezing process. By drawing air through each pallet, heat is pulled away as quickly as the product will release it. According to the company, every case on each pallet freezes at the same rate in a predictable, repeatable pattern.
