What is a Coffee Roaster
Many people today start their day with a cup of strong and refreshing hot coffee. Do you wonder how to make high-quality coffee with exceptional fragrance? What can you do to fully enjoy your coffee and feel energized all day long? The answer is simple - roast and grind it yourself! For this purpose, various kinds of coffee roasters are specially designed to obtain evenly roasted coffee at home. The roasting process is fairly simple - just put raw green coffee beans into the drum or the bowl, where they are treated with hot air and mixed up. Normally, beans are cooled with forced air after roasting. In fact, a good coffee roaster is what makes your coffee exceptionally fresh with deep, rich flavor, and aroma.
What Features to Compare
Once you make a decision to get a coffee roaster, the first thing you should pay attention to is the Type and the Heat Source of a roaster machine. Typically, there are drum and air coffee roasters that generally differ in their methods of roasting. To put an air coffee roaster into operation, you need to load beans into the bowl, which is heated by forced hot air, constantly stirring the beans during the roasting process. Normally, the roasters of this type are quieter and faster in operation, but they are characterized by a rather small roasting capacity (about 0.2 - 0.3 lbs). On the contrary, drum coffee roasters are usually of a larger size that allows grinding larger amounts of coffee beans at a time. When using the coffee roaster of this type you need to turn on the machine, put beans into the drum and close it while the beans are being stirred continuously. Commonly, coffee roasters use electronic and gas heat sources. To get started, an electric coffee roaster requires connection to the mains whereas a gas coffee roaster needs a gas stove to heat it to the required temperature. However, there are some exceptional models with a combined heat source, i.e. the roasting is done by means of heated gas, but also requires a network connection to put the drum into operation.
Another important feature is the Performance of the coffee roaster. The capacity and the roast time influence the performance of the machine. It's necessary to find out how many family members basically drink coffee, how much coffee they drink per day and how strong it is. This helps you understand what amount of roasted coffee you need so that you don't have to repeat this procedure too often. For instance, 1/4 pound of coffee will be quite enough for a family of two coffee lovers per week. Since you’re going to regularly roast coffee beans, it’s important to choose a coffee roaster that will maximally preserve the natural taste and flavor of coffee beans. In general, the roast time depends on the roast profile you prefer - delicate light or very dark roast. Apparently, the light roast profile requires shorter roast time compared to the darker one. The roasting time will also vary with adding more or less coffee beans at a heat.
Another feature that you need to take into consideration is the Usability of the coffee roaster that is influenced by controls, functions, and size. There are models with an electronic, mechanic, and manual type of controls currently available on the market. Some coffee roasters require constant control of the roasting process, while others make the roasting process more automated, which means you need to select a program, set the capacity and weight, and the machine will do the rest. Furthermore, dimensions play an important role when it comes to finding the right place for your home coffee roaster in the kitchen. One more useful feature is a see-through window in the drum coffee roasters and a clear bowl in the air coffee roasters; both are very handy to more accurately determine the level of readiness and roasting. An additional bonus is a cooling cycle, which allows the beans and the machine to cool quickly and reduces the risk of skin burns. Since coffee emits smoke and odor during the process of roasting, some models feature a patented smoke suppression technology that requires no additional air vent and there is also no need to ventilate the room where you roast your coffee. What is more, a coffee roaster comes with a removable chaff tray, making cleaning the roaster much easier and convenient.
