Coffee roasters are mechanical devices to make coffee so much better! These are available in many different sizes and shapes. The prices of these coffee roasters can range from just around twenty dollars up to nearly one thousand dollars! The more expensive a coffee roaster is doesn't necessarily mean that it is any better. It's a good idea to purchase a coffee roaster from a reputable company. How complicated do you want? Coffee roasters serve a different role than your usual Bunn or traditional coffee maker. Some people really enjoy being scientific when making coffee, they might like to blend their own coffee. Roasters allow different degrees of mixing.
Some are quite simple devices which are stove top devices. These are basically just simple saucepans with a tight lid. These systems contain a crank which can be used to mix the beans while boiling them.
It is essential to stir the beans to prevent them burning on the bottom of the pan. If you are choosing one of these types of coffee roaster then you should choose a design which has some form of thermometer. You can also get more advanced (and expensive) roasters which can do everything for you. You just need to put some beans in, push a few buttons and then walk away while it does its job. These advanced models have a thermostat built in which allows them to control the temperature exactly. The whole process is controlled by a timer which means it will shut itself off when it is complete.
How effectively do they heat and circulate air? By far the most popular form of coffee roaster are ones that work in the same way as a popcorn maker. They use hot air which is passed through the beans while they are continually moved around. This makes sure that every bean gets the same heat and prevents them from burning. Most of these can also filter out the skins from these beans. Most of these coffee roasters have glass lids which allow you to watch as the process is completed.
Most allow you to vary the degree of roast by twisting a dial which adjusts the temperature. It is very important that coffee roasters circulate the air evenly so that the beans can be roasted properly. Better coffee roasters allow you a lot of control over the temperature and circulation of heat. Drum roasters ensure an even circulation of heat and air by rotating the beans continuously in a drum. These use gravity to move the beans rather than a stirrer.
If you like to watch while the machines roast your coffee beans then you should carefully choose a coffee roaster which has windows. These windows are particularly important if you want to experiment with the blend. If you want to roast lots of beans then you should be aware that it will generate huge volumes of smoke. Coffee roasters only used to be used by professionals; however they are now becoming more and more popular for use in your home. They are particularly useful for people that entertain a lot.
