sügavkülmikus

Sügavkülmik is the Estonian word for a deep freezer or chest freezer. It is an appliance designed to maintain a consistently low temperature, typically around -18 degrees Celsius (0 degrees Fahrenheit) or lower, to preserve food for extended periods. This low temperature inhibits the growth of microorganisms, slowing down the spoilage process and allowing food to be stored for months.

Deep freezers come in various sizes, from compact countertop models to large, freestanding units. They are commonly used in households to store a variety of items such as meat, poultry, fish, fruits, vegetables, baked goods, and pre-prepared meals. Commercial establishments, like restaurants and supermarkets, also utilize larger, industrial-grade deep freezers to manage their inventory and reduce food waste.

The principle behind deep freezing is to reduce the temperature of food to a point where water within the food is converted into ice crystals. This process immobilizes the water, making it unavailable for enzymatic and microbial activity that causes food to spoil. Proper packaging is crucial when using a deep freezer to prevent freezer burn, which is a form of dehydration that occurs when food is exposed to cold, dry air. Vacuum sealing or using airtight containers and freezer-grade bags are common methods for protecting food during deep freezing.
