The modern mechanical refrigeration process we know today grew from the work of numerous inventors in the 1800s. American Jacob Perkins invented the first vapor compression system in 1834, while German professor Carl von Linde patented a new process for liquefying gases in the late 1800s.
When did refrigerators replace ice boxes?
All of this contributed to the improvement of the population’s health by increasing the fresh food readily able to be consumed and the overall safety of that food.

How much did a fridge cost in 1920?
When the refrigerator did appear, it was a luxury. In the 1920s, when a Model T Ford cost as little as $260, the first Frigidaire cost roughly $750. Fridges remain a big-ticket item, often the most expensive kitchen appliance.
When were ice boxes used?
1840s. The first iceboxes were made by carpenters, designed to take advantage of the regular household delivery of large blocks of ice. They were insulated wooden boxes lined with tin or zinc and used to hold blocks of ice to keep the food cool. A drip pan collected the melt water – and had to be emptied daily.
How did they get ice in the Old West?
Up in your part of the country, they’d harvest ice from the rivers in the winter time and store it in caves or rock cellars. It would usually last most of the summer. Outside of Flagstaff were some ice caves, and saloonkeepers would harvest ice from the caves during the summer.
How was ice cream made before refrigeration?
Before the development of modern refrigeration, ice cream was a luxury reserved for special occasions. Making it was quite laborious; ice was cut from lakes and ponds during the winter and stored in holes in the ground, or in wood-frame or brick ice houses, insulated by straw.
How was food kept fresh 300 years ago?
Salting was the most common way to preserve virtually any type of meat or fish, as it drew out the moisture and killed the bacteria. Vegetables might be preserved with dry salt, as well, though pickling was more common. Salt was also used in conjunction with other methods of preservation, such as drying and smoking.
How did people store cheese before refrigeration?
In fact, refrigeration in true terms did not even exist until post second world war. Until then, a cool and dark storage space is all that was required to store cheese. Cheese stays fresh unrefrigerated inside a cool pantry or a storage room for months at a stretch. Next step is to wrap the cheese inside cheesecloth.
How did they store ice in the old days?
For millennia, those rich enough got servants to gather snow and ice formed during the winter and stored it in straw-lined underground pits called ‘ice houses’.
How long did a block of ice last in an icebox?
For food storage, get block ice when you can — block ice will last 5 to 7 days in a well-insulated ice box even in 90-plus-degree weather (and longer if it’s cooler). Cube ice will only last one to two days.

What came first the fridge or the freezer?
In 1913, refrigerators for home use were invented. In 1923 Frigidaire introduced the first self-contained unit. The introduction of Freon in the 1920s expanded the refrigerator market during the 1930s. Home freezers as separate compartments (larger than necessary just for ice cubes) were introduced in 1940.
How much did a TV cost in 1980?
