Evolution of Food Preservation: From Ice Delivery to Modern Freezing Technologies

Ice cream is cherished worldwide, enjoyed after meals or as a treat. Today, it's readily available, but before freezer technology, storing frozen treats was a challenge.

Traditional Preservation Techniques

Prior to the 19th and 20th centuries, people used natural methods to keep food cold. In winter, ice workers harvested snow, salted it, and stored it in underground cellars for months. This ice was then distributed as needed.

Household cooling was achieved with wooden containers insulated with materials and packed with snow and ice, known as "ice boxes." These provided brief refrigeration, lasting about a week before melting or losing coldness.

Advancements in Freezing Technology

The development of modern refrigeration began in the 1700s. Scottish scientist William Cullen experimented with evaporating ethyl ether in a vacuum. Throughout the 1800s, innovators like Oliver Evans and Michel Faraday improved cooling methods using liquefied gases like ammonia. Jacob Perkins built the first practical refrigerator in 1835, earning recognition as the "father of refrigeration."

In 1842, John Gorrie created ice-making machines that influenced future designs. Later technological pioneers such as Ferdinand Carre, Carl von Linde, and Albert Einstein contributed to refining the process. The first commercial upright freezer debuted in 1913 by Fred W. Wolf, transforming food storage. By then, breweries widely used these freezers to chill beverages.

Functioning of Commercial Upright Freezers

These units operate using refrigerants that flow through coils. The refrigerant vaporizes, capturing heat from inside, then releases it outside through coils, before being compressed back into liquid. This cycle maintains consistent chilly temperatures.

Modern Commercial Chilling Equipment

Initially, coolants like CFCs were popular, but environmental concerns arose in the 1920s. By the 1970s, safer alternatives like hydrofluorocarbons (HFCs) were adopted, although they still pose environmental challenges.
