Coffee Makers

Coffee Makers, cooking appliances having different varieties and methods to brew the coffee have removed the inconvenience to boil the water in different containers. In the very initial stage roasted and ground coffee beans were placed in a pot or pan to which hot water was added followed by attachment of a lid to commence the infusion process. An idea to change the process of brewing coffee finally made the first modern method for making coffee. The biggin, originating in France ca. 1800 was a two-level pot holding appliance in which coffee was placed in an upper compartment and water was poured to drain through holes in the bottom compartment into the coffee pot below. In the next development process of coffee makers, a French inventor developed the "pumping percolator" in which boiling water in a bottom chamber forces itself up a tube and then trickles through the ground coffee back into the bottom chamber.

Vacuum Coffee Brewer:

Vacuum Coffee brewer: a bodum vacuum brewer where the coffee is sucked back. The Napier Vacuum machine invented in 1840 was an early example of this type. The principle was to heat water in a lower vessel until expansion forced the contents through narrow tube into upper vessel containing ground coffee. When the lower vessel was empty and sufficient brewing time had elapsed then heat was removed and the resulting vacuum draw the brewed coffee back through a strainer into the lower chamber from which it could be decanted.

The next variant technique called a balance siphon having two chambers arranged side by side was the next coffee brewing method. On August 27, 1930 Inez H. Pierce of Chicago, Illinois invented the first vacuum coffee maker that truly automated the vacuum brewing process. An electrically heated stove was incorporated into the design of the vacuum brewer.

Electric Percolator:

James Nason of Massachusetts patented the early percolator design in 1865. An Illinois farmer named Hanson Goodrich is credited with patenting the modern percolator. The impact of science and technological advances as a motif in post –war design was eventually felt in the manufacture and marketing of coffee and coffee-makers.

Consumer guides emphasized the ability of the device to meet standards of temperature and brewing time, and the ratio of soluble elements between brew and grounds. In later years, coffee makers began to adopt more standardized form commensurate with a large increase in the scale of production required to meet postwar consumer demand. Plastics and composite materials began to replace metal, particularly with the advent of newer electric drip coffee makers in 1970s. During 1990s, consumer demand for more attractive appliances to complement expensive modern kitchens resulted in new wave of re-designed coffee makers in a wider range of available colors and styles.

Modern Coffee Maker

We find three things in the top of this coffee maker:

• There is a reservoir that holds the water when you pout it into the pot at the start of the coffee making cycle.
• There is a white tube that leads up from the below the reservoir base, carrying the hot water up to the drip area.
• There is a shower head. Water arrives here from the white hot-water tube and is sprayed over the coffee grounds. In some coffee makers, the water comes out of the hose into a perforated plastic disc called the drip area and simply falls through the holes into the coffee grounds.
