Drum Commercial Coffee Roasters

As the name suggests, a drum roaster is a coffee roasting machine with a specially designed cylinder-shaped chamber used to make roasted coffee. This chamber, known as a drum, is where the coffee beans are placed, set to a temperature, and rotated until the beans crack. To create your perfect coffee roast, you can experiment with several factors, such as drum speed, temperature, airflow, length of roast, and more. These days, you can get high-quality drum coffee roasters to boost your coffee-drinking habit.

Sample Coffee Roasters

A sample coffee roaster is a small-scale roasting device used to experiment with and assess coffee beans. Small batches, usually between 50 and 300 grams of beans, let roasters experiment with various roast styles. This aids in figuring out the best roasting conditions, including temperature and duration, to produce the required flavour profiles. Before committing to larger batches, roasters can evaluate the possibilities of new coffee bean kinds with sample roasters, which are crucial instruments for quality control. Additionally useful for instructive and instructional purposes, they aid baristas and coffee connoisseurs in understanding the nuances of roasting.

• Size and Density: The Probat Sample Roaster is built to support a batch capacity of 200g coffee beans. On the other hand, the Aillio Roaster is designed to roast 1 kg of coffee beans.
• Heating Time: The Probat Roaster has a roasting time between 10 to 15 minutes, and the first crack appears at 7 to 8 minutes. The Aillio Roaster can make the first crack appear in 1 kg of beans in under 12 minutes.
• Ease of Use: Deciding on a roast profile becomes easy since the Probat Roaster has few controllable variables. The Aillio Roaster has an easy interface that allows you to control several variables during the roasting process, such as heating power, drum speed, and fan speed. The roaster will enable you to take a sample mid-roast. You can also get a glimpse of the beans through the glass.
• Quality of Coffee Roasts: The Probat roaster results in an unexceptional flavour of the coffee. The product of roasted coffee in an Aillio roaster is also delicious and flavour-rich.
  The Probat and Aillio are both exceptional drum roasters that can offer flavourful coffee with roasted coffee beans. While the Probat is simple to use, the Aillio provides more scope for experimentation.

Types of Coffee Roasts

1. Light Roasts(Common name: New England, Half-City, Cinnamon).
   Light coffee roasts are roasted for less time, generally at 350 to 400 degrees F. Light roasts will not have that oily texture in their body as they are not roasted for long at high temperatures. They generally come in light brown. The longer you roast a bean, the more heat it pulls, increasing the caffeine and acidity. Hence, light roasts have the most caffeine content and are highly acidic. Lightly roasted coffee beans are mainly used in specialty coffee industries and cafes to deliver premium-rich, unique flavours out of coffee.

2. Medium Roasts(Common names: City, Regular, American).
   Medium-roasted coffee beans are roasted from 410 degrees F to 425 degrees F. Compared to light-roasted ones, medium-roasted coffee beans have less acidity. An average coffee drinker generally uses medium roast coffee beans as they come with balanced flavours. This roast is medium brown with a strong taste and non-oily body. Medium coffee roasts are also known as American roasts, as Americans prefer this type of roast.

3. Dark roasts(Common name: French, Espresso, Turkish, Italian, Dark French, Heavy)
   The ideal temperature to roast a dark coffee bean is 430 degrees F and 460 degrees F. This is heavily roasted coffee with a slight tinge of spiciness in the taste. You can see the oily texture in the body. With a rich and sweet flavour, this dark roast coffee is ideal for making Espresso and French roast. Also, dark roast coffee contains the least caffeine, as it is roasted at high temperatures for a long time.

To make sure your industrial coffee roaster suits your demands, consider the following considerations before investing:

• Roasting Consistency and Quality: To guarantee consistent, excellent roasts, use a roaster with precise temperature, airflow, and drum speed control systems. Choose between gas and electric variants depending on your preferred level of control.
• Automation and User-Friendliness: Seek features that automate processes, reduce training time, and have user-friendly interfaces.
• Energy Efficiency and Environmental Impact: Be mindful of the fuel consumption of your roaster and ensure it has emissions controls in place to comply with environmental laws. By choosing an energy-efficient roaster, you’re saving on costs and contributing to a greener future, a responsibility we all share.
• Size and area Requirements: Verify that the roaster is the right size for the area you have available and has the proper ventilation systems.
• Reputable brands with a solid dependability and quality track record should be chosen. Good customer service and readily available components should also be provided.
• Cost and Budget: Consider fuel and maintenance expenses while weighing the initial expenditure against the required features.

We have listed down great coffee roasting machines which have been coffee industry leaders for decades.

• Probatone Gas Roasters: Shop/Commercial Roasters: Drum roasting is the most common method. Here, the coffee is roasted in a drum that rotates around a horizontal axis. The PROBATONE shop roasters use specially developed shovel mechanisms to move the beans inside the drum. A surface burner heats the roasting air before it is sucked through the back wall of the drum as well as guided around it, thus roasting the beans not only via convective but also conductive heat transfer. With roasting capacities ranging from 17 to 85 kilograms of roast coffee per hour (kg/h), the PROBATONE shop roasters are particularly suitable for small to medium-sized roasting facilities with high-quality demands on the product.
• Bullet Aillio Electric: Personal / Sample Roaster: The Bullet R1 is a 1KG personal/sample proper drum coffee roaster. Automatic drum pre-heating, adjustable heat and fan speed, and continuous real-time feedback provided by infrared bean and drum temperature sensors combine for precise, consistent roasting. Easily capable of bringing one kg of beans to first crack in under 12 minutes, a remarkable feature for a roasting machine that fits neatly on your kitchen counter and plugs into any standard wall socket. Details of each roast can be digitally recorded and saved as roast profiles that can then be replayed or shared between roasters. Easy to clean and maintain. Induction heating system with over 95% efficiency.
• Kaldi Gas Roaster: Sample Roasters: The Kaldi Roaster looks and operates like giant roasting machines in the back of commercial roasting facilities. It’s just a lot smaller.

The Kaldi Coffee Roaster is a powerful workhorse without bells and whistles. While you won’t find timers and rows of buttons, you’ll have complete control over all the variables, such as drum temperature, roasting time and drum speed. This manual spirit makes the Kaldi roaster an excellent tool for learning the nuances of coffee roasting. You can’t just sit on the sidelines. You must participate. Become an artisan. The Kaldi is well-built and quite smart-looking. It’s a shiny stainless-steel roaster made of heavy gauge materials—very sturdy for a home roaster.
