In order to help you know more about coffee machines, below, I will share the development history of coffee machines for you, hoping to help you!
Incubation period: coffee is extracted before 1900? Perfect steam theory? 18 18, Dr. Romershausen got a project in Prussia? Extractor? Patents.
1822, a Frenchman Louis Bernard Rabout obtained a patent, which was based on the characteristics of blotting paper and the design of Dr. Romershausen to obtain a cleaner extract.
1824, Caseneuve, a Parisian craftsman, designed a coffee utensil that was too complicated to make, hoping to avoid the loss of aroma.
In 1827, French Laurens patent emphasizes that coffee powder should be wetted with steam before extracting coffee.
1833, Samuel Parker, an Englishman, invented a pump to pump water up into coffee instead of letting it flow down through it.
1838, Le Bourne, an optician in Paris, designed various small desktop coffee machines, which were very popular in southern Europe.
In 1840, Tiesset designed a vacuum pump to pull down hot water and transfer coffee powder with extra force.
1844, the Frenchman Cordier drew many coffee extractors in his patent application, one of which was very similar to Eicke's German machine 30 years later.
1847, Romershausen made a steam pressure coffee pot.
1855, the Frenchman Loysel introduced a large-capacity bar coffee machine (about 4.5 meters high), claiming that it could make 10000 cups of coffee every day.
1868, Reiss from Vienna developed a new type? Vienna pot? .
1885, Italian Angelo Moriondo signed a patent for coffee, which can make 50 cups at a time.
Childhood: the exclusive privilege of one cup of coffee at a time 190 1 year Luigu Bezzera successfully applied for a patent for the coffee machine.
1902, his friend Desiderio Pavoni added a pressure relief piston device to this machine, and also commercialized this machine.
1903, Bezzern sold the patent right to Pavoni at the price of 10000 lira due to financial difficulties.
1905, Rapavone Company was founded.
1906, the Italian Arduino applied for a patent to install a heat exchanger in the machine to quickly heat water.
1909, Luigi Giarlotto added a pump to the machine, thus solving the problem of insufficient pressure during extraction.
19 10, his second patent is a spiral piston, which can squeeze all delicious coffee out of the piston.
1935, Dr. Yili invented the first machine that used compressed air to push water through coffee powder.
Starting from 1938, the boiler was successfully placed horizontally instead of vertically.
Puberty: the pressure increases and the water temperature decreases. Gold bubble? With the birth of 1948, Gaggia introduced the piston rod spring coffee machine to the market.
1952, the large vertical machine disappeared overnight.
In 1956, Cimbali uses a hydraulic system to avoid consuming too much effort when using the lever.
After 1962 matures: the popularization of electronic parts? Heat exchange, thermal cycle? 1955, Giampietro saccani has taken important measures to keep the temperature stability of the brewing head.
196 1 year, Italy and Spain cooperated to produce E6 1 car. Hot water used to be pressurized, but now it is a perfect revolution to pressurize and then heat it.
