A roasting coffee beans machine is a device used to transform green coffee into roasted coffee seeds. It allows users to roast their own coffee at home, resulting in fresher and more flavorful brews. A home roaster provides control over the roasting process, allowing coffee lovers to customize the flavor and intensity of their coffee to their own personal preference. 

Roasting Coffee Beans Machine

As a long-time coffee roaster and café owner, I’ve worked with all types of professional coffee grill machines. If you’re looking to upgrade from home roasting methods to commercial-grade equipment, choosing the right roasting machine is key. In this comprehensive guide, I’ll walk through the different types of industrial coffee roasters, their key features and differences, and provide tips for selecting the best machine for your needs.

Roasting Coffee Beans Machine

Coffee roasters can be broadly divided into three categories:

  • Drum roasters
  • Hot air roasters
  • Fluid bed roasters

Each type uses different mechanisms to transfer heat into the beans and achieve the desired grill level. Let’s look at how they work.

If you want to roast your own coffee at home, the Kaldi coffee roaster is a great option for home use. With this equipment, you can customize the roasting process to suit your taste preferences. It ensures a fresh roast every time, removing the chaff that can affect the flavor. The Kaldi is compatible with different types of coffee, allowing you to experiment and discover new flavors. Plus, it can be easily used on a gas stove for convenient roasting. 

Drum Roasters

Drum roasters are the most common commercial coffee roasters. They consist of a horizontal rotating steel drum that tumbles the beans as it rotates over a heat source.

Key Features:

  • Drum shape enhances uniform heat transfer
  • Rotation agitates beans for even roasting
  • Direct contact with metal drum
  • Roastingtemperatures between 370-540°F
  • Consignment sizes from 5-150 lbs

There are two subtypes of drum roasters, namely the direct drum roaster and the indirect drum roaster. The direct drum roaster has a flame source that directly heats the drum, while the indirect drum roaster uses heated air or steam to heat the drum indirectly. Both types of drum roasters are commonly used in the coffee industry to grill coffee seed. 

For a high-quality grilling experience, a stainless steel stovetop roasting equipment is a great choice. With this hands-on method, you can grill coffee beans per set, ensuring the freshest and most flavorful brew. Additionally, the stainless steel construction ensures durability and easy cleaning, making it a convenient option for any coffee lover. 

Direct Fire Roasters

Direct fire drum roasters heat the drum directly with a gas or wood flame. This gives great control over temperature but can impart some smoky flavors if not used properly.


  • Precise heat control
  • Imparts unique flavor


  • Risk of smoke taint
  • Harder heat adjustment

In 2023, home coffee roasters have become increasingly popular, especially small consignment coffee roasters. These machines, like the Direct Fire Roasters, not only allow coffee enthusiasts to roast their own beans at home, but they also provide an effortless cleanup process.

With the help of advanced technology, these coffee seed roaster machines have made it easier for coffee lovers to enjoy freshly roasted coffee right in the comfort of their own homes.

Indirect Fire Roasters

Indirect drum roasters use hot air to heat the drum externally. This provides a “cleaner” roast flavor without smokiness.

Indirect drum roasters use hot air to heat the drum externally. This provides a "cleaner" roast flavor without smokiness.


  • No smoke flavor
  • Easier to control temperature


  • Less temperature precision
  • Slower heat response time

For most coffee shops, an indirect drum roaster offers the best balance of flavor control and ease of use.

Roast StyleDrum Type

Hot Air Roasters

Hot air roasters use a powerful fan to circulate hot air around the coffee beans as they tumble around inside the roasting chamber.

Key Features:

  • Roasting via convection with hot air
  • Temperatures between 392-572°F
  • Fast, efficient heat transfer
  • Consignment sizes from 1-150 lbs

Hot air roasters allow very precise control over the roasting process. But the beans don’t have as much direct contact with a heated surface compared to drum roasters.

Hot Air Roasters


  • Excellent temperature control
  • Very even roasting


  • Beans may lack “drum character”

Hot air roasters are great for advanced users looking for maximum control and consistency. Their computerized controls simplify hitting target roast profiles.

Fluid Bed Roasters

Fluid bed roasters float beans on columns of hot air to roast them. The beans hover and swirl above perforated plates through which the hot air flows.

Key Features:

  • Roasting via hot air suspension
  • Temperatures between 230-545°F
  • Smaller consignment sizes from 0.5-45 lbs

The fluidized bed creates very efficient heat transfer for faster grilling times. But these machines can be noisy and more expensive.


  • Very fast, efficient roasting
  • Compact size


  • Noisy
  • More expensive
  • Less traditional roasting smell/taste

Fluid beds work well for micro-lot specialty roasting due to their small consignment capabilities and speed. They simplify making many small-batch roasts.

Tips for Selecting a Roaster

Picking the right coffee machine for your needs depends on many factors:

When it comes to choosing the right coffee machine, there are several factors to consider. First and foremost, you need to determine your specific roasting needs. Are you planning to roast coffee for personal use or for a small coffee shop?

This will help you determine the size and capacity of the machine you require. Additionally, you should consider the level of automation you desire.

Batch Size

Consider your expected production volume. Smaller roasters like fluid beds work for micro-lots. Larger drum roasters are needed for high-volume commercial roasting.

The batch size is an important factor when it comes to commercial coffee roasters. The Fresh Roast SR540 coffee roaster machine is known to handle small batch sizes efficiently. Specialty coffee enthusiasts often prefer smaller batch sizes as it allows for better control and precision in the roasting process. For those looking for the best commercial coffee roasters, the Fresh Roast SR540 is highly recommended. Its ability to roast small batches, while maintaining quality, makes it a top choice for specialty coffee roasters. Desired Roast Style

Certain roasters excel at different roast levels. For example, hot air roasters simplify nailing light roasts while direct-fire drums are great for dark roasts.

When it comes to coffee, each individual has their own desired roast style. Some prefer a light roast that brings out the natural flavors of the coffee beans, while others enjoy a dark roast that offers a bold and rich taste. Commercial coffee roaster machines play a crucial role in achieving the desired roast style by applying the right temperature and time for coffee bean roasting. Ultimately, it is the coffee drinkers who benefit from this process, as they get to enjoy their preferred coffee flavor profiles. 


Larger machines have higher startup costs. Smaller 1-3 lb roasters can produce small bundles on a budget. Prioritize key features over size/capacity.

A budget is essential for any small business to effectively manage its expenses and revenue. It allows owners to track their financials and make informed decisions about their operations. By creating a comprehensive budget, small businesses can also one, plan for future growth and ensure they have enough funds allocated for necessary expenses. 

Techniques Used in Traditional Coffee Roasting method

Small bunble coffee roasters typically grill coffee in small quantities per batch, allowing them to carefully control the roast profile and bring out the unique flavors of the beans. To achieve this, they use specialized small bunble roaster machines that provide precise temperature and timing control. This attention to detail results in high-quality coffee with distinctive flavors, bringing out the best in each kind of coffee. 

Roast Speed

Some applications require faster roasting time. Fluid beds roast very quickly while indirect drums are slower. Make sure the roast speed suits your workflow.

If roast speed is important to you, then you need to consider the coffee roasting equipment on our list. Whether you’re a professional or a home coffee enthusiast, finding the ultimate roaster that allows you to adjust the temperature is crucial. Don’t settle for anything less when it comes to achieving the perfect roast. 

Additionally, it has been found to have higher levels of antioxidants compared to other types of coffee. These antioxidants can help protect against certain diseases and promote overall health.


Check that the roaster dimensions and utilities fit your space. Larger machines need more floorspace, ventilation, gas, etc.

Commercial coffee machines have a significant footprint due to their size and capacity for larger roasting. These machines offer a roasting game with various bells and whistles, ensuring the perfect roast every time. Additionally, they are designed to be one of the quietest coffee machines in the market, ensuring a peaceful coffee roasting experience. 

Noise Level

Roasters create noise during operation. Fluid beds are louder than drums/hot air roasters. Ensure acceptable noise levels for your facility.

When it comes to the ultimate coffee experience, the noise level can greatly influence the ambiance and overall enjoyment. A quiet and serene environment allows for better focus and appreciation of the coffee’s taste and aroma. Additionally, when choosing a coffee, it is important to look for quality and freshness. Roasting small amounts ensures that the coffee is at its peak flavor and intensity, providing a truly satisfying coffee experience.

Support & Service

Look for roaster companies that offer training, service, and support. Having assistance dialing in roasts is invaluable, especially for new users.

When it comes to support and service, it’s also one of the essential factors to consider if you’re looking for the ultimate experience. Whether it’s in the form of prompt response to customer queries or personalized assistance, a seamless support system can make a significant difference in customer satisfaction and loyalty.
