The Kitchen Refrigeration Unit is one of the most essential sets of kitchen equipment used for the preservation of food items. The primary purpose of a refrigerator is to keep food products cool. Cold temperatures keep food fresher for longer. The fundamental theory behind refrigeration is to slow down the growth of bacteria which all food contains so that the bacteria can no longer spoil the food products. Many types of bacterial developments are slowed by refrigeration as they can be found anywhere in existence.
