The Coffee Roaster, which is a mechanical device, comes in all type of shapes and sizes.
This particular machine can also range in a few hundred dollars to nearly a thousand in prices. However, in this case a high priced product does not usually guarantee that it will be a high quality machine. This article will help you to choose the perfect coffee roaster by giving you helpful tips on what machine to choose.
How much involvement do you want?
When you decide to buy a coffee roaster you should also think about how much you will be involved in roasting the beans. There are many of us who like to experiment by mixing, stirring and measuring the roast. If you are like one of these people then you should go for the special roasters. Most roasters are just stovetop models that have a saucepan with a tight lid and a special handle.
This model also has a crank in the handle that lets the roaster to kindle the beans at some point in the process of roasting. One of the most important processes in roasting is stirring. This helps by preventing the coffee beans at the bottom from burning and by keeping the air inside hot by circulating it evenly.
In roasting, temperature control is extremely important. So, when you go to buy a roaster, be sure to look for one that has a thermometer in it. Even if you buy a simple model, look for one that has a thermometer in it.
Another type of roasters is the ones that do all the work for you. All you have to do is pop in a pre-determined volume of green beans from the bag and then let the machine do all the work.
In-built thermometers, thermostat control heating mechanisms, rotating canisters, clever airflow control and a timer to shut off the device at the appropriate time, are all present in the deluxe models of the coffee roaster.
The rocket-ship roasters that are present on the upper-end of the price range do all the work for you, but eliminate the smoke that is often accompanied in the process.
How effectively do they heat and circulate air?
One of the most important aspects of a coffee roaster is its effectiveness in heating and then circulating the air. Almost all the common roasters work on the same principles as a popcorn popper machine. In these machines, while the beans are being agitated the hot air is circulated throughout the inside of the machine. This process helps to give a uniform roast to the beans. There are also many machines that filter out the chaff that are produced when the skin burst due to the expansion of the coffee beans.
There are also many machines that allow to you watch the roasting process. This can help you to judge how much of the roast do you want for the beans. These machines often have pre-set amounts, ranging from light to dark, on the dials.
One critical point for the machines is the ability to circulate hot air evenly. Most of the machines and their design vary extensively in the degree of roasting. For instance, if a machine has the heating source in the bottom then it will give out an uneven roast to the beans.
You will not face this problem in a Drum roaster machine. Rather than relying on a stirrer at the bottom, this machine has a drum that uses the forces of gravity to move the beans around in the machine.
Coffee roasters, which were once just confined to professional use, have evolved extensively and can be used for kitchen purposes also. These cappuccino makers also have the added benefit of roasting large quantities of beans, which can be very useful during large dinner parties. With the help of these machines you will also be able to serve the freshest cup of the brew to your friends and for your self.
