REVERSIBLE AIR FLOW EVAPORATORS
The cooling and freezing of food is one of the most important applications of refrigeration. The process of cooling
and freezing food effectively reduces the activity of microorganisms and enzymes, slowing deterioration.
Furthermore, the crystallization of water reduces the amount of liquid water in food and inhibits microbial growth
(Heldman 1975). The majority of food refrigeration and freezing operations use blast freezers in a batch process,
while a number of products are cooled or frozen by spiral, fluidized bed, or plate freezers.
