One that is not as popular as all the others is the vacuum machine. They come in many shapes and sizes yet they are more alike than they are different. This system heats the water in the lower chamber creating a water vapor. This increases the pressure in the lower chamber and forces the water upward into the upper chamber that you add just before the water begins to rise. Brew for about 1.5 minutes then remove from heat the gases in the lower chamber cool and draws the brewed coffee downward via suction caused by a partial vacuum that ensures accurate extraction of oils and caffeine for a cleaner unit without the bitter taste.
After the initial purchase of a single serve coffee machine which ranges in price from $85 to $190 the cost per cup of coffee is much less than that of a cup of coffee from a gourmet coffeehouse. The average cost per cup of coffee is anywhere from $0.65 to $1.25 with a Keurig coffee machine. Compare this to upwards of $5.00 per cup at a coffeehouse. You will save a lot of money with the single serve coffee brewer.
In the present era it is almost unimaginable to think of a book store or a browsing hall without a coffee machine at a corner or featured most prominently. With so many people hooked on to this drink big time the coffee machine has slowly started finding its way through schools colleges workplaces malls and even petrol pumps. Many institutions and companies offer free service to their patrons while some of them charge a negligible fee for using the facility. Overall walk into a shopping mall or a complex arcade and there are more chances than ever for you to find Commercial Coffee Makers somewhere in the backdrop.
In 1938 Milan coffee bartender Achille Gaggia filed a Patent for a steam-free coffee machine. Unlike its predecessors Gaggias design used a revolutionary piston mechanism which forced water through the coffee grounds at high pressure. It was his quest for the perfect espresso in 1930s Milan that gave birth to one of Italys most iconic brands and heralded the production of the Espresso as we know it. Traditional Espresso Coffee Machines are the type you see in Café Nero Costa Coffee etc.
