Lead Image

Deep freezers are chest shaped refrigeration appliances that can store large amounts of food at very low temperatures for long term preservation. They're more popular than ever, these days, as people around the world increasingly prepare for long periods with no access to shopping markets in response to events like COVID-19 and the ongoing climate crisis.

Industrial deep freezing may refer to the process of rapidly cooling food to below negative 30 degrees Celsius. The speed of this process can help maintain some of the textural and health qualities of food for commercial applications.
