Coffee roastingis an important stage in the coffee-making process that affects its flavor, aroma, and final quality. Currently, there are various types of roasting machines available, one of which is the hot air coffee roaster.
In recent years, hot air coffee roasting machines have become popular among coffee lovers and coffee business people. This machine uses hot air to evenly distribute heat throughout the coffee beans to be roasted. However, as with every technology, hot air coffee roaster machines also have advantages and disadvantages that need to be considered before deciding to buy and use one.
Steps to Use Hot Air Coffee Roaster
Here are the general steps for using a Hot Air Roasting machine:
Coffee Bean Preparation
Prepare the coffee beans that will be used for roasting. Make sure the coffee beans are cleaned and prepared according to your preferences.
Grilling Profile Adjustment
Set the Hot Air Coffee Roasting machine according to your desired roasting profile. The roasting profile includes temperature, roasting time, and stirring speed. Each machine may have different settings, so be sure to refer to the user manual provided by the machine manufacturer.
Preheat the Engine
Start the engine and let it warm up to the desired temperature. The heating process may take a few minutes depending on the machine you are using.
Add Coffee Beans
Once the machine is heated, put the prepared coffee beans into the machine. Make sure that the coffee beans are evenly distributed so that the roasting can go well.
Supervise and Control the Roasting Process
During the roasting process, pay close attention to the development of the coffee beans. Some machines come with transparent windows or lights that allow you to see the grilling directly. Pay attention to the temperature, time, and stirring speed, and adjust if needed to achieve the desired roasting profile.
Cooling
Once roasting is complete, turn off the machine and immediately remove the roasted coffee beans from the machine. To cool the coffee beans quickly, you can use a cooling device or place them on a surface that does not heat up easily.
Store and Leave Coffee Beans
Leave the coffee beans for some time, usually around 12 to 24 hours, so that the flavor of the beans can develop properly before use or storage.
It is however advisable to follow the user manual provided by the manufacturer of the Hot Air Coffee Roasting machine you will be using. Each machine can have different features and settings, so be sure to understand how it works specifically. Also, constant practice, experience, and experimentation will help you understand how to optimize the use of these machines to achieve the desired results.
