Coffee Makers, Grinders & Machines

Coffee Makers

Gracing the countertops of many kitchens around the world are coffee makers. These special appliances play an important part in many people's morning routines, and they are soon becoming as common as the microwave.

Coffee makers come in all shapes and sizes, but the traditional coffee maker operates on the same brewing fundamentals and consist of similar components. Ground coffee beans are place on a permeable paper filter (sometimes metal) inside of a funnel. Immediately above is a section where cold water is poured into.

This water is then brought to a boil and discharged into the funnel containing the coffee beans, and is later drained out of the machine in the form of hot coffee. This type of coffee maker is sometimes referred to as a drip coffee maker.

Espresso coffee machines differ from the conventional coffee makers in a few key areas. In particular, they necessitate a precise amount of heat and pressure.

Coffee Grinders

There are three main stages of coffee preparation before that perfect cup of gourmet coffee can be served. The procedure includes roasting coffee beans, grinding the beans, and the application of hot water to the ground coffee. Coffee grinders are coffee machines which turn whole coffee beans into a powdered or near-powdered form. Grinded coffee needs to be vacuum packed to minimize the amount of oxidation.

Grinding coffee can be accomplished through four different methods: burr grinding; chopping; pounding and; roller grinding.

Burr grinding is the tearing apart of beans by two revolving grating pieces, which produces evenly sized coffee particles. Coffee grinders that chop the beans involve sharp blades rotating at high speeds, producing fragments that could differ in size. Pounding creates the finest level of coffee powder and is done with a mortar and pestle (bowl and heavy stick). Roller coffee grinders are preferred by the industrial coffee makers.
