As a barista, you must know the development history of coffee machine.

Gestation period: the "perfect steam theory" of coffee extraction before 1900

In 1800, Archbishop D'Bello of Paris invented the waterdrop coffee maker.

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: exclusive privilege of one cup of coffee at a time, 1901-1947

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.
