Coffee - Coffee Roasters
November 17th, 2008Coffee roasters vary in almost every way from extremely technical to very simple. The cost varies as greatly as the styles you can choose from. Certain manufactures are trusted to make a quality product and these are not always the most expensive. But in addition to quality and cost there are other factors to be considered.
How much involvement do you want?
Some roasters are designed very simply and leave more of the technical work to you. They merely serve as the heating device while you are responsible for measuring and mixing to get the desired result.
The handle contains a crank that allows the roaster to stir up the beans during the process. Stirring is essential to keep the beans from burning on the bottom as well as to keep the hot air inside circulating evenly.
Even in this simple set up, be sure to look for ones that have a thermometer in the lid. Temperature control is important for proper roasting.
Other roaster models need almost no help from you. The instructions give you the amounts. Then you simply attach the cover and wait.
This sophisticated type of roaster has everything built in and removes all guess work. It has a temperature gage which constantly monitors the heat and adjusts itself accordingly. There is no need for stirring because there are built in mechanics that keep the hot air circulating and the beans in perfect motion. These models even shut themselves off when the beans are ready.
At the upper end of the price range, these rocket ship roasters do everything but eliminate the smoke that invariably accompanies the process.
Efficient air circulation and heat
Air roasters work by rotating hot air in through the beans while also keeping the beans in motion. This will roast your coffee beans evenly and in some models even clean away the unwanted residue left over when the shell of the bean expands and bursts.
Most allow you to watch the process through a glass exterior, to judge the degree of desired roast. Frequently they have pre-set amounts on the dial ranging from light to dark.
