The latter is more common with lower-volume commercial installations and domestic espresso machines. Espresso machines are made to accept water directly from a cold water line supply, common in commercial installations, or from a separate tank that must be filled with water by hand.
PERSONAL EXPRESSO MACHINE MANUAL
Instead of using manual force, a motor-driven pump provides the force necessary for espresso brewing. This results in the crema, a hallmark of an espresso, being of lower quality.Ī refinement of the piston machine is the pump-driven machine, which was introduced in the Faema E61 in 1961, and has become the most popular design in commercial espresso bars. Also, steam-driven machines do not produce as high a pressure for extraction compared with pump-driven. This design is still used today in lower-cost consumer machines, as it does not need to contain moving parts. The first espresso machines were steam types, produced when a common boiler was piped to four group heads so that multiple types of coffee could be made at the same time. The Illetta became the predecessor of today's espresso machine.Ī steam-driven unit operates by forcing water through the coffee by using steam or steam pressure. In 1933 Hungarian-Italian Francesco Illy invented the first automatic coffee machine that substituted pressurized water for steam. In 1905 the patent was bought by Desiderio Pavoni who founded the La Pavoni company and began to produce the machine commercially (one a day) in a small workshop in Via Parini in Milan. It was titled "Innovations in the machinery to prepare and immediately serve coffee beverage" (Patent No. He patented a number of improvements to the existing machine, the first of which was applied for on 19 December 1901. Bezzera was not an engineer, but a mechanic. In 1901, Luigi Bezzera of Milan patented improvements to the machine. Moriondo had his machine built in a very limited number, using it in a few establishments he owned, such as the American Bar in the former Galleria Nazionale on Via Roma in Turin, demolished in the 1930s. Angelo Moriondo, of Turin, for an invention called "New steam machinery for the economic and instantaneous confection of coffee beverage, method 'A. A certificate of industrial title was awarded to Mr. 33/256 dated (according to the "Bollettino delle privative industriali del Regno d'Italia", 2nd Series, Volume 15, Year 1884, pages 635 – 655). One of the precursors of the first machine for making espresso was built and patented by Angelo Moriondo of Turin, Italy, who demonstrated a working example at the Turin General Exposition of 1884.
