The Evolution of Commercial Coffee machines the "perfect Steam Theory" of Coffee extraction

Gestation period: before 1900

Perfect Steam Theory of Coffee extraction

In 1818, Dr. Romershausen obtained a patent for "extractor" in Prussia.

In 1822, the Frenchman Louis Bernard Rabout obtained a patent to obtain a cleaner extract based on the characteristics of oil-absorbing ink paper combined with the design of Dr. Romershausen.

In 1824, Caseneuve, a Parisian craftsman, designed a coffee utensil that was too complex to make, hoping to avoid the loss of aroma.

In 1827, Laurens's patent in France emphasized the need to wet coffee powder with steam before coffee extraction.

In 1833, Samuel Parker, an Englishman, invented using a pump to pump water up through coffee instead of letting it flow down. (he paid special attention to the fact that the good taste of coffee first appeared bitter and was extracted in the later stage.)

In 1838, Leburn, an optician in Paris, designed a number of small table coffee makers, which were very popular in southern Europe.

In 1840, Tiesset designed a vacuum pump to pull hot water down with extra force through coffee powder.

In 1844, Frenchman Cordier painted a number of coffee extractors in his patent, one of which was very similar to Eicke's German machine 30 years later.

In 1847, Romershausen made a steam pressure coffee pot.

In 1855, the Frenchman Loysel introduced a large-capacity bar coffee machine (about 4.5m high), which claims to make 10000 cups of coffee a day.

In 1868, the Viennese Reiss developed a new type of "Viennese pot".

In 1885, the Italian Angelo Moriondo signed a patent for coffee that could make 50 cups at a time.

Childhood: 1901-1947

Exclusive privilege of one cup of coffee at a time

The coffee machine designed by Luigu Bezzera in 1901 was successfully patented.

In 1902, his friend Desiderio Pavoni added a pressure relief piston device to the machine and commercialized the machine for production and sale.

In 1903, Bezzern sold the patent to Pavoni at a cost of 10, 000 lire due to financial difficulties.

In 1905, La Pavoni Company was announced.

In 1906, the Italian Arduino applied for a patent to install a heat exchanger in the machine to heat the water quickly.

In 1909, Luigi Giarlotto added a pump to the machine to solve the problem of insufficient pressure in the extraction.

In 1910, his second patent was the screw-down piston, which squeezed out all the delicacies of coffee from the piston.

In 1935, Dr. Illy invented the first machine to use compressed air to push water through coffee powder.

Since 1938, the placement of the boiler has been successfully improved from the original vertical to horizontal.

Puberty: 1948-1961

The pressure increases and the water temperature decreases; the birth of the "gold bubble"

In 1948, Gaggia introduced the piston lever spring coffee machine to the market.

In 1952, the large vertical machine disappeared overnight.

In 1956, Cimbali used hydraulic systems to avoid consuming too much effort when using levers.

Maturity: after 1962

The popularization of electronic parts; the advantages of "heat exchange and heat cycle"

In 1955, Giampietro Saccani took an important step to keep the temperature of the cooking head stable.

In 1961, Italy and Spain jointly produced the E61 model. In the past, hot water was pressurized, but now it is pressurized and then heated, which is a perfect revolution compared to the past.
