How Reversible Air Flow Evaporators Reduce Freezing Time
Refrigeration’s most important application is the preservation of food. Cooling and freezing food effectively reduces the activity of microorganisms and enzymes, thus slowing its decay. Here’s how reversible air flow evaporators help cold food processors achieve longer freezing times and a variation in product quality based on placement in the freezer.
How fish freezes Fish unloaded from the vessel are usually graded by the buyer according to species, size and minimum quality specification. A price is based in part on the quality in relation to market requirements. Fish also may be inspected by local and federal regulatory agencies for wholesomeness and sanitary conditions. Organoleptic criteria are most important for evaluating quality however there is a growing acceptance, particularly in Canada and some European countries, of objective chemical and physical tests as indexes of quality loss or spoilage.
