The Siena Cappuccino Machine - A Process Description

 

Introduction

The Siena cappuccino machine (figure 1) forces about 1.5 ounces of hot water through tightly packed ground espresso coffee and creates a small amount of extremely strong coffee resulting in a dark brown, slightly thick liquid that is sometimes added to milk, which creates cappuccino.  The Siena cappuccino machine process consists of four parts: programming, grinding, brewing, and warming.

Programming

The Siena cappuccino machine allows users to program the strength of coffee by touching a button that tells the machine how strong the coffee should be.  Also the cappuccino machine allows users to program the cup size, the milk foam amount, the water temperature, and the rinse and clean by touching a button that then sends a signal to the machine.  There is also a timer on the machine that turns the machine of after a certain period off time (Figure 2).

Grinding

Adjustable grinding allows the grinding process to be less noisy and prevents less dust particles by the keeping the coffee ground in a special compartment (figure 3).  The adjustable grinder also allows the machine to consistently produce a perfect grind of coffee.

Brewing

The automatic brew chamber brews two cups of cappuccino in a single brewing cycle by having a single pump (figure 4) with two sets of programmers attached to it.

Warming

The double product dispenser has a heating element located directly beneath the cups to allow constant warming of the cappuccino.  The warmer can be on or off to the discretion of the user.
