People apply electronic technology to the coffee maker machine to realize automatic control of the whole process of coffee brewing, such as grinding, pressing, filling, brewing, and removing residue. In the early twentieth century, an engineer living near Naples, Italy, was impatient with the dripping and brewing coffee for too long, so he came up with a method while waiting. That is to make coffee at high temperature and high pressure to shorten the time, so invented Italian coffee quick conditioning, the coffee and espresso maker also became popular.
In 1884, Angela Morioondo of Italy demonstrated the first espresso coffee machine at the World Expo in Turin, and registered and applied for a patent named "steam-operated fast coffee making equipment". This was the most advanced steam equipment for making coffee beverages at that time.
This big machine has a big boiler that heats the water to a pressure of 1.5 bar. The amount of water is adjusted according to the demand, and the steam produced by another boiler is flushed through the coffee powder to complete the coffee brewing. The emergence of Italian espresso machine has undoubtedly become an important turning point in the world coffee culture.
Although Angela Morioondo first invented the espresso machine, he did not put his invention into industrial production. It was not until 1901 that Milan designer Luigi Bezzera first registered the patented technology of commercial espresso machine that could be used in commercial production. In 1905, La Pavoni purchased its patent and used this technology to formally produce a coffee machine for the first time. The first true Espresso Machine came out.
It looks very different from the current espresso machine. Ideale's brewing head has a maximum temperature of 140°C and its pressure is 1.5 bar lower than the 9 bar of modern machines. The Espresso is extracted within 45 seconds, and its body and taste are inferior to modern espresso machines (black coffee with almost no fat). Due to the emergence of the first generation of espresso machines, the word "Espresso" was first introduced in an Italian dictionary (by Alfredo Panzini) around 1920, with the annotation as "Espresso made using a pressurized machine or filter."
By 1947, the espresso machine ushered in a qualitative development. Milan barista Achille Gaggia invented the piston manual lever coffee machine. This machine can use greater pressure to extrude crema, making the taste and flavor of espresso richer. In 1948 Gaggia’s invention was acquired by Faema. Then, in 1961, Faema released the Faema E61, which is now world-renowned. This coffee machine uses a water pump to stabilize the water pressure to 9 bar, and the heat exchanger can also keep the brewing water temperature stable. Many structural ideas of the current espresso machine originate from this machine. Achille Gaggia is called the father of modern semi automatic espresso machine.
And now as a leader in the coffee machine industry, La marzocco has been popular in the 1970s until today. The coffee shops on the streets and lanes are lined with machines of various models.
In 1927, two brothers Giuseppe Bambi and Bruno Bambi founded La marzocco in Florence, Italy. In 1939, Giuseppe Bambi registered a patent for the horizontal boiler coffee machine he invented. The previous coffee machine boilers were all upright and very tall. The design of the horizontal boiler makes it possible to add more brewing heads in the body and simplify the operation of the coffee machine. And the first coffee machine to use button extraction and the first to use dual boilers were La Marzocco.
Nowadays, there are many types of coffee machines, such as smart espresso machine, pressure coffee maker and hand drip coffee maker and so on.
