Coffee Bean Roaster

The process of roasting the coffee beans which are the seeds of a berry that grows on a coffee tree or shrub is done with a roaster. The coffee trees and shrubs tend to like a moderate tropical climate and the beans are grown at different altitudes. The coffee bean is processed once or twice a year either by hand or by mechanical ways.

Coffee beans that are off a gourmet variety are then sold to a large coffee bean roaster company or green coffee brokers. Green coffee is also called raw coffee. From the coffee bean roaster it is sorted and sometimes processed again. Then the coffee bean is put in large drum machines to be roasted. The coffee is then sealed in bags and sent to the market.

If you want the entire java experience including buying green or raw beans and then roasting them at home, you’ll need your own coffee bean roaster. A roaster is a drum shaped machine and the heat is brought to the drum by different ways such as by electricity, gas fire, or by infra red means. The heat generated by the coffee bean roaster through metal in the drums is termed “conductive roasting.” There is another kind of class of this type of coffee bean roaster which is combination drum roasting. This type of roasting uses a hot stream of air which is streamed into the drum of the roaster. This is much like roasting the coffee beans on a sheet inside of an oven.

Another type is one that uses hot air to roast the beans. In this type of roaster an extremely hot stream of air is forced into the roaster and it suspends and cooks the beans as this is called convention roasting. This type of roasting takes less time but there is a limit to how many beans one can roast using this type of coffee bean roaster. So you can roast coffee faster using this type of coffee bean roaster but you will not be able to roast as many beans doing it.

You can go high tech to get your initial caffeine fix every day by using infra-red waves to roast the beans. This method of coffee bean roasting is efficient as it brings much energy into the beans but it takes a longer time to roast the beans than with a convectional coffee bean roaster.

If you want to spend the time or money involved to make your coffee from almost scratch get yourself a roaster and get to work.
