The invention of the electric freezer is a milestone in the history of refrigeration, and it’s a story that is often overlooked. The electric freezer revolutionized the way people stored and preserved food, making it possible to keep food fresh for longer periods of time. But who was the lady behind this groundbreaking invention? In this article, we’ll explore the story of Mary Andrus, the woman who invented the electric freezer.
The Early Days of Refrigeration
Before the invention of the electric freezer, people relied on iceboxes to keep their food cool. Iceboxes were essentially large containers filled with ice that was delivered to homes on a regular basis. However, this method had its limitations. Ice was expensive, and it would often melt quickly, leaving food spoiled and rotten. The search for a more efficient and cost-effective method of refrigeration was underway.
In the late 19th century, several inventors and scientists were working on developing refrigeration systems. One of the most notable was Fred W. Wolf, who invented the first electric refrigerator in 1913. However, his design was not practical for widespread use, as it was expensive and required a lot of electricity.
Mary Andrus and the Electric Freezer
Mary Andrus was an American inventor and entrepreneur who was born in 1861. She grew up in a family of modest means and was encouraged by her parents to pursue her interests in science and technology. Andrus studied electrical engineering and began working for the General Electric Company (GE) in the early 1900s.
In the 1920s, Andrus was tasked with developing a more practical and affordable electric refrigerator. She spent years researching and experimenting, and in 1922, she patented the first electric freezer. Andrus’ design was revolutionary because it used a compressor to compress and expand refrigerant, which allowed for more efficient cooling.
The First Electric Freezer
Andrus’ first electric freezer was a large, box-like device that stood over 6 feet tall. It had a compressor on top, a condenser coil on the back, and a fan to circulate the cold air. The freezer used a refrigerant called methyl chloride, which was a common substance used in refrigeration systems at the time.
The first electric freezer was not without its challenges. Andrus had to overcome numerous obstacles, including the difficulty of finding a reliable and affordable source of refrigerant. She also had to deal with the skepticism of many people who doubted the feasibility of her invention. (See Also:How Long Can Sourdough Bread Last In The Freezer)
The Impact of the Electric Freezer
The electric freezer had a profound impact on society. It made it possible for people to store food for longer periods of time, which reduced food waste and improved public health. The electric freezer also enabled people to live in areas with warm climates, where refrigeration was previously not possible.
The electric freezer also had a significant impact on the food industry. It allowed for the mass production of frozen foods, which revolutionized the way people ate. Frozen foods were no longer a luxury item, but a staple in many households.
Benefits of the Electric Freezer
The electric freezer had numerous benefits, including:
- Improved food storage: The electric freezer allowed people to store food for longer periods of time, reducing food waste and improving public health.
- Increased food availability: The electric freezer made it possible for people to live in areas with warm climates, where refrigeration was previously not possible.
- Mass production of frozen foods: The electric freezer enabled the mass production of frozen foods, which revolutionized the way people ate.
- Cost-effective: The electric freezer was a cost-effective solution for refrigeration, as it used less energy than traditional iceboxes.
Conclusion
Mary Andrus’ invention of the electric freezer was a groundbreaking achievement that had a profound impact on society. Her design was revolutionary because it used a compressor to compress and expand refrigerant, which allowed for more efficient cooling. The electric freezer made it possible for people to store food for longer periods of time, reducing food waste and improving public health. It also enabled people to live in areas with warm climates, where refrigeration was previously not possible.
