How does flash freeze work?

Flash Freezing food focuses on rapidly freezing the product so as to maintain proper retention of moisture, flavor and texture. It accomplishes this via high speed internal cooling. It rapidly cools down the internal temperature in the freezer, making it much easier to ensure efficient cooling for the product.

How does a blast freezer work?

Blast chillers or freezers operate by blowing forced cooled air over food placed inside. When defrosting food, large ice crystals melt and cause excess moisture to release, which largely impacts the taste and quality of your food products.

What is the difference between flash freezing and freezing?
