History of the Refrigerator
Back in time a long time ago, around 500 B.C. the Egyptians and Indians made ice on cold nights by setting water out in earthenware pots and keeping the pots wet. In the 18th century England, servants collected ice in the winter and put it into icehouses, where the sheets of ice were packed in salt, wrapped in strips of flannel and stored underground to keep them frozen until summer. Before the refrigerator or "ice box" was introduced people used snow and ice to keep their food cool, which was either found locally or brought down from the mountains. Cellars and caves were also used to refrigerate food. Meat and fish were preserved in warm weather by salting or smoking. The first cellars were holes dug

Compressed ether machines were built in Pennsylvania by Oliver Evans in 1805 and in Australia by James Harrison in 1855, and Dr. John Gorrie in Florida built an expanding air-cooling machine in 1844. In 1851 Dr. John Gorrie created the first commercial ice making machine to cool the air for his yellow fever patients. Soon thereafter, refrigeration and freezing became popular methods of preserving foods for transport or storage, and in place where natural ice was not available.
Refrigeration is the process of removing heat from an enclosed space, or from a substance, to lower its temperature. A refrigerator uses the evaporation of a liquid to absorb heat. The liquid, or refrigerant used in a refrigerator evaporates at an extremely low temperature creating freezing temperatures inside the refrigerator.
William Cullen at the University of Glasgow demonstrated the first known artificial refrigeration in 1748. However, he did not use his discovery for any practical purpose. In 1805, an American inventor, Oliver Evans, designed the first refrigerator machine.
The development of mechanical refrigeration systems began in the early19th century and arose mainly from the needs of meat producers in the USA, South America, Australia and New Zealand, who were facing many difficulties in shipping their produce to their export markers in Europe. Many experimental systems were built in the 1830s, utilizing the cooling effect produced by the expansion of
The article “Not in my fridge” by Jeffery M. Smith elaborately discussed the health hazards of genetically modified (GM) products. This article has opened my eyes and revealed my ignorance of how unmindful of what I have eaten for years. I was very alarmed by many of the things I have learned in this article. After learning the side-effect of GM food, I was certainly concerned for our health. Moreover, learning that the biotech company’s strong stand in advocate of GM products as well as the United States governments and the Food and Drug administration (FDA) cover up of serious safety issues of GM highly disturbed me.
Augustus Jackson was born on April 16, 1808. He was a worker in the White House when he moved from his hometown in Philadelphia. In the 1820’s he was a teenager he became one of the top chefs. Then he quit and moved back to Philadelphia and he opened his own shop as a caterer and a confectioner. When working with ice cream he discovered that mixing rock salt and ice the salt will act as a neutral object that controls and lowers the temperature of the ingredients he used for his ice cream. When he made this discovery he started to sell it inin street vendors and in ice cream parlors. He found this out in 1834. Soon after the invention he was named the ‘the father of ice cream’. Although he didn’t actually invent it. Some historians say that
Roy Seider had experience of selling high-end coolers so that he began designing his own line of durable coolers keeping ice frozen far longer with materials. His brother, Ryan, sold his Waterloo Rods company that he had owned and

Clarence Birdseye is commonly known as the founder of the modern frozen food industry. An entrepreneur, American inventor and naturalist, Birdseye began his career as a taxidermist. Birdseye's next field assignment, off and on from 1912 to 1915, was in Labrador in the Dominion of Newfoundland (now part of Canada), where he became further interested in food preservation by freezing, especially fast freezing. He was taught by the Inuit how to ice fish under very thick ice. In -40°C weather, he discovered that the fish he caught froze almost instantly, and, when thawed, tasted fresh. He recognized immediately that the frozen seafood sold in New York was of lower quality than the frozen fish of Labrador, and saw that applying this knowledge would
~ In 1650, Von Guericke created the first powerful air machine. With such a machine, Robert Boyle had the capacity to experiment pressure and decompression of creatures.
1846, ice cream started to develop and evolve. Just after this time, it quickly spread and the first hand-cranked ice cream freezer was invented in the US at this time.
Matthew gitzinger invented the first and revolutionary reusable gas on 2042 ,december 1st at the age of 40 years old he changed the world of transportation but he was not alone on this invention he had help and not ordinary help in this invention he had some world renowned scientist by his side the dream of reusable gas has been one of many but his dream has grown big.
Target consumers and the condition now: Students in the college. Most students (up to 52%) are likely to accept an increase of $75 per year to use a Microfridge, and at $50 per year the interest level is 90%. But the authority suspects the quality and the security of the product.
The invention of ice cream can be traced back to the fourth century (BC) but was never really “discovered” until the 1600’s. Much about the history of ice cream has been left to the imagination but historians can give credit to the chef of Charles 1 of England. After much preparation, the King's French chef had concocted an apparently new dish. It was cold and resembled fresh- fallen snow but was much creamier and sweeter than any other after- dinner dessert. The guests were delighted, as was Charles, who summoned the cook and asked him not to reveal the recipe for his frozen cream. The King wanted the delicacy to be served only at the Royal table and offered the cook 500 pounds a year to keep it that way. Sometime later, however, poor Charles fell into disrespect with his people and was beheaded in 1649. But by that time, the secret of the frozen cream remained a secret no more. The cook, named DeMirco, had not kept his promise. It is likely that ice cream was not invented, but rather “came to be” over years of similar efforts. Indeed, the Roman Emperor Nero Claudius Caesar is said to have sent slaves to the mountains to bring snow and ice to cool and freeze the fruit drinks he was so fond of. Centuries later, the Italian Marco Polo returned from his
Around the Middle Ages many European countries were already making desserts that were made from cream. But because there weren’t any freezers or refrigerators at the time, ice cream had to be served immediately or it would melt. When the technology for refrigeration and freezing were not advanced yet, cooks would be able to tell step by step how to make mixtures for cream but not how to keep them cold. So with more understanding on the cooling process, they were able to make what they called “cream ice”. The Arabs were the first known people to know how to make ice. Italians and French learned of their techniques and were fascinated by using both ice and salt to freeze mixtures and keep them cold. Later on ice houses were being made as kind of their version of a refrigerator. This way people were able to have ice year
Created in 1960, it was primarily focused on refrigeration components when it was first established. Due to overgrowing demand, Metalfrio began selling commercial
Refrigerators are manufactured in two basic designs which are referred to as Direct Cool (DC) and Frost Free (FF) refrigerator.
This technology is far less commonly applied to refrigeration than vapor-compression refrigeration is the primary advantages of a Peltier cooler compared to a vapor-compression refrigerator are its lack of moving parts or circulating liquid, very long life, invulnerability to leaks, small size and flexible shape. Its main disadvantage is high cost and poor power efficiency. Many researchers and companies are
