Coffee History the Origin of Commercial semi-automatic Coffee machines

Incubation period: before 1900

Coffee extraction "perfect steam theory"

In 1818, Dr. Romershausen patented an "extractor" in Prussia.

·In 1822, French Louis Bernard Rabout obtained a patent that used the characteristics of ink absorbing paper combined with Dr. Romershausen's design to obtain a cleaner extract.

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

Laurens 'patent in France in 1827 emphasized the need to moisten coffee powder with steam before coffee extraction.

In 1833, Samuel Parker invented a pump to pump water up through coffee instead of down through it. (He noted, in particular, that the good taste of coffee comes first and the bitter taste is extracted later.)

·In 1838, Paris optician Leburn designed a variety of small table coffee machines, 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, Cordier, a Frenchman, drew a number of coffee extractors in his patent application, one of which was similar to Eicke's German machine 30 years later.

In 1847 Romershausen made a steam pressure coffee pot.

In 1855, French Loysel introduced a large-capacity bar coffee machine (about 4.5 meters high), claiming to make 10,000 cups of coffee a day.

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

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

Childhood: 1901-1947

One cup of coffee at a time. Exclusive privileges.

In 1901, Luigu Bezzera patented a coffee machine designed by him.

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

In 1903 Bezzern sold the patent to Pavoni for 10,000 lire due to financial difficulties.

In 1905, La Pavoni was founded.

In 1906, the Italian Arduino patented a heat exchanger built into the machine to heat water quickly.

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

In 1910, his second patent was a screw-down piston that squeezed all the flavor out of coffee.

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

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

Adolescence: 1948 - 1961

Pressure increases, water temperature decreases; birth of "gold bubble"

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

In 1952, the large upright disappeared overnight.

In 1956, Cimbali used a hydraulic system to avoid using too much force when using levers.

Maturity: after 1962

Popularization of electronic components; advantages of "heat exchange and heat circulation"

In 1955, Giampietro Saccani took the important step of maintaining the temperature of the brewing head stable.

In 1961, Italy and Spain cooperated to produce the E61 model. In the past, hot water was pressurized, but now it is pressurized and then heated, a perfect revolution from the past.
