The Working Principle of Coffee Makers

Coffee makers go through a series of intricate steps to transform the aroma and flavor of coffee beans into the beloved beverage we enjoy. Firstly, the coffee maker heats water to an optimal temperature, typically between 195°F to 205°F, ensuring that volatile compounds in the coffee beans are adequately extracted. Next, the hot water passes through a filter, coming into contact with the coffee grounds, allowing solutes from the coffee beans to dissolve into the water. This process, known as extraction, involves chemical reactions such as dissolution, diffusion, and adsorption. Finally, the coffee flows into a glass carafe, ready to be savored. Behind this process lies a multitude of disciplines including thermodynamics, chemistry, and physics, making the coffee maker an engineering marvel.

Noise Level

The Zojirushi EC-EJC120 coffee maker operates quietly. There is some noise during the brew cycle from the water pump and heating element, but the sound is comparable to other drip coffee machines. It won’t be disruptive if brewing coffee while others are sleeping or working nearby.


The removable parts including the filter basket, shower head, and carafe are dishwasher safe, making cleaning the coffee maker quick and easy. The control panel just needs an occasional wipe down with a damp cloth. Descaling every 3-6 months ensures continued trouble-free operation.

Energy Efficiency and Sustainability

Energy efficiency is an important indicator of sustainability when evaluating coffee makers. Some advanced coffee maker designs incorporate energy-saving technologies such as smart temperature control systems and automatic shut-off functions to minimize energy consumption. Additionally, some manufacturers are committed to using sustainable materials and production processes to reduce environmental impact. Purchasing a coffee maker with high energy efficiency and sustainable materials not only saves energy costs but also contributes to reducing carbon footprint and environmental protection efforts.
