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.
There is a separate Grinder which usually sits on top of a Knockout Drawer which is used for the spent coffee pucks. Although most Traditional Espresso Machines have automatic dosing these days the coffee making process is by hand (Artisan). The coffee shot; single or double is prepared using the machine. The milk is foamed using the machine Steam Wand. The coffee is then put together to make any one of the most popular coffees. Cappuccino Latte Mocha and Macchiato etc. All of the preparation adds to the "Theatre" of the Coffee Culture. Customers have a higher perception of an "Artisan Coffee" and are willing to pay more. Training is required to ensure quality and consistency.
High volume would be 200 - 500 cups per day. Bean to Cup machines will protest if asked to do more than they were built to do and will appear slow at busy times. There are no major training requirements to use a Bean to Cup machine. No Barista skills are really needed. Some of the more powerful high volume Bean to Cup machines have traditional Steam Wands so some "foaming" skills may be needed. Training is more to do with how to use and look after the machine. Cleaning is especially important when using a Bean to Cup machine. Its a good idea to have some knowledge of coffee beans so you can choose a blend that will to suit your customers tastes.
Apart from all these structural and quality considerations it is also worthwhile to consider the kind of coffee that you might want to serve. There are more than thousand varieties of coffee available right from the Café Mocha to the South Indian Filter Coffee; coffee with milk and without milk; coffee with sugar and without sugar; coffee with chocolate toppings or with a vanilla sundae on it. The possibilities are endless and so are the machines. There are different machines that are used to create various types of coffee and thus as the methods of creating the coffee vary the internal design and the make of the system also varies.
