We will cover various coffee roasters and highlight essential factors to consider, including costs, to help you make a wise decision. We'll also guide you on how to check different brands and models so that you can choose the right coffee roaster for your needs.
The types of machines available in the marketplace are the first step in selecting the best for your company. Why? Because each type has their pros and cons. The manufacturing capacity, desired class, level of control, and budget are all factors that will determine your decision.
Drum roasting is a widely used method for roasting coffee beans. This technique of roast involves placing the beans inside a cylindrical chamber called a drum. The drum is then rotated, and the beans are evenly roasted using heat sources such as an open flame, electricity, gas, or wood.
As the drum rotates, the beans are uniformly exposed to the heat source, ensuring they are roasted on all sides. This drum and method is effective in producing consistent and even roasts. Regularly turning the drum is crucial to guaranteeing that all beans receive the same heat level, preventing any from being over or under-roasted.
Drum roasting is popular because it allows for precise control over the roasting method, resulting in a high-quality coffee product. While other methods are available, drum roasting remains a preferred method for many roasters due to its reliability and consistent results.
Fluid-bed roasting is a popular hot-air method to roast coffee beans. This involves pushing hot air through a bed of coffee beans, causing them to circulate and roast evenly. This produces a bright and vibrant flavor profile.
One of the critical advantages of fluid-bed roasters over other types is their cost-effectiveness. Fluid-bed are generally less expensive to operate than drum roasters, making them popular for small coffee businesses and home roasting.
These roasters are also known for their efficiency. The hot air allows for faster and more consistent roasting, allowing you to save time and energy.
While most machines from major companies can roast a good amount of coffee, some have features that makes it challenging to achieve top-quality, even with skillful hands.
Such features include thin, single-walled drums, slow gas valves, poor resolution valves at low temperature settings, excessive insulation around the drum, slow or poorly positioned probes, and limited control of roasts after the first crack.
Asking those with experience with all major brands is essential when seeking advice on which machine to buy. Experts that have only used one or two machines tend to favor them and lack perspective about other options. It's also important to avoid relying on the advice of sales associates. They are often biased and misinformed about competing brands.
You must consider some factors that could impact the success of your business. These are: the standard of your coffee, and the effectiveness of your operations when choosing the best equipment for your business. You can gain a better understanding of the valuable roasters out there. This includes their advantages as well as their disadvantages, and how they match with your company's objectives.
Keep your spending limit in mind while making an machinery purchase. It would be beneficial to get a larger roaster than you formerly believed you needed, if your budget allows it. In the case of most roasters, many of them regret buying a machine they outgrow too rapidly rather than regretting buying a larger equipment. The goals and needs you have must be prioritized according to your budget after assessing the initial costs.
Choosing the right machine size requires knowing how much coffee you'll be making each week for the next two years. This includes the projected amount of weekly production during the next two years. Get a big roaster that can crank out that much in 25 hours. Remember that a bean loses 14% to 20% of its weight during roasting, so a machine's actual capacity may be lower than its quoted capacity.
Reputable brands produce products that are backed by strong warranties and customer service. This gives you confidence in your purchase. To have a better understanding of a machine's reliability, it is a good idea to consult other users. Most roasters are eager to share their expertise, including any difficulties they may have encountered. When it comes to the quality of the roasts they create, roasters are less objective than when it comes to the dependability of their machinery.
Most might take this for granted, but a well-designed user interface is crucial when purchasing a roaster. Especially if you intend to use it for many hours each week. Quality, consistency, comfort, and ease of use of the roast can all be affected by the user interface. The use of machinery that requires you to press an up or down button to adjust the gas settings might be time-consuming and aggravating. It's simpler and more enjoyable to handle a device with an analog gas dial or a smart touchscreen.
The machines' electric power supply and the computer control that comes with the item are factors that need to be thought of. Top chefs favor gas-powered machine because using a gas stove is safer and less expensive than using an electric one when cooking. Gaining control of it is vital because even small adjustments during roasting have a big impact.
The extra features and accessories that can enhance your experience are other factors that you need to think about. The roasting will be more successful if your setup includes the appropriate elements and extras.
Cooling Trays - cool roasted bean rapidly to preserve their ideal flavor and aroma. Some machines have built-in trays, while others require a separate cooling system.
Chaff Collection Systems - Chaff is the thin, papery skin covering the bean that separates as it expands and dries. If not managed properly, it can be hazardous in a roastery. Chaff collection systems prevent chaff accumulation and keep the roastery clean.
Software Integration - offers greater roast control and the ability to create, save, and replicate profiles. Some machines come with exclusive or third-party software, which should be evaluated for ease of use, data logging, and connectivity (USB, Bluetooth, Wi-Fi).
Smoke Suppression Systems - Smoke from roasting can be an issue for companies in crowded areas or governed by strict local regulations. Smoke suppression systems can help mitigate this problem by filtering smoke and particles and collecting them through ventilation. These systems often include air filters and may have afterburners to eliminate any remaining smoke.
Commercial brewing unit can cost anywhere from $250 to $300. These machines are drum-based that weigh around six pounds. This drum size can roast about six pounds of bean per minute.
A small tabletop model of acommercial machine with a capacity of around 1-5 pounds per batch may cost between $3,000 to $7,000. Medium-sized machinery with a capacity of 10-30 pounds per batch typically range from $10,000 to $30,000, while larger machines with 30 pounds or more per batch can cost anywhere from $30,000 to $100,000.
The size and capacity of the machine significantly impact the cost. Larger machinery with higher capabilities tend to be more expensive than smaller ones.
The features and integrated technology can also affect the cost. A machine with advanced features such as computerized controls, smoke abatement systems, and data logging capabilities is more expensive.
Established and reputable brands may charge higher prices due to their reliability, performance, and customer support.
Electric ones are less expensive upfront but may have higher operating costs, while gas machinery may have higher upfront costs but lower operating costs.
Can coffee roasters produce profit? Well, roasting coffee can be lucrative and an excellent opportunity to grow coffee businesses. Most of these problems are related to the initial cost of building machinery which can reach $100,000.
Another factor that can impact profitability is the quality of the bean used for roasting. Higher-grade coffee beans can lead to a better-tasting final product. Sourcing coffee beans from farmers or cooperatives can help reduce costs and improve the sustainability of the supply chain.
The pricing of the final product is also critical for the profitability of coffee roasting. When setting the price of coffee, roasters should consider the production costs, administrative costs, and the cost of similar products on the market.

Ever wonder what happens after you press the charge button on your roaster? Yes, the beans get roasted, but what steps does the roaster go through to get them to your desired color, flavor profile, and moisture content? While the specific process varies depending on the roaster type and options this is a general overview of the entire Industrial Coffee Roasting Process.
The Roaster has been preheated, and there is a batch in the Charge (Feed) hopper. When you press the charge button the roaster checks a few things before allowing the beans to be dropped (Charged) into the drum. These processes all happen simultaneously.
The Roaster first checks it has a place to discharge the batch when complete. The roaster then begins to bring the temperature up to Charge Temperature. If you have an exhaust abatement system, the roaster may also check to ensure it is running and at temperature before charging. Once all the parameters are met, the gate opens, and the beans begin their journey.
Curve Tracking&#; This process allows for a much tighter control of the roasting process and can help ensure consistent quality of your roasts. Before using Curve Tracking you must have developed a recipe that meets the quality requirements for that &#;Recipe&#;. Curve Tracking uses a record (Master Batch) of the actual temperatures and settings of the roaster throughout an initial (Master Batch) roast to control the roast process. This allows for consistent roasts even during different ambient conditions.
During the roasting process it is important to keep a negative pressure inside the drum, this helps to ensure a good flow of air is continually moving through the beans in the roaster (as seen below), and any smoke and CO is exhausted out of the building. This is achieved by the speed of the roast fan, and control of various flaps. If you have ever noticed a roaster that seems to release a lot of smoke into the building, that is a sign that something could be causing the pressure inside the drum to be positive. This is what allows the smoke to escape from the roaster into the building.
Recipe Control &#; This process simply follows the recipe you have selected. The Roaster monitors the current product (Bean) temperature and adjusts various settings per the recipe. This is changed per &#;stage&#; as each stage is triggered by the temperature set in the recipe. These settings include various settings such as burner percentage, fan speed, etc. The roaster continues through the stages until it reaches to the final bean temperature.
Quenching&#; When the bean temperature has reached the final temperature set in the recipe or the curve profile, the roaster prepares to discharge the beans. The beans are very hot and will continue to roast even if they are removed from the heat. The roasting process also removes quite a bit of moisture from the beans, quenching helps to not only cool the beans, but add some moisture back to them. You may have an option to set a &#;Quench Delay&#;, this is a delay after the beans reach their final temperature until the quenching process starts. Once this time has elapsed, the roaster will quench the beans with a specified amount of water. This value is controlled via the recipe. Depending on roaster type, you may have the ability to do a &#;First Quench&#;, or &#;Pre-Quench&#; This limits the amount of water introduced to the beans at first to reduce the amount of steam that is created. Once the time or quantity of First Quench has been reached, it will then continue to quench until the desired total quench amount has been released. If you experience water pressure issues at your facility, you may get a quench fault (Roaster Quench Overtime Fault). The roaster monitors the total time the quench process takes, if it exceeds a calculated time, this fault will occur. When the quenching occurs, steam is created when the cold water hits the hot beans and drum, this causes the drum pressure to increase so it needs to be able to pull that extra volume out and release it. Depending on the roaster, it may open the exhaust flap or increase the roast fan speed to help remove the excess pressure.
Drying&#; Once the quench process is complete, the roaster is in its Drying stage. This process is as simple as it sounds. The roaster does not release the beans until the Drying Time has elapsed. This allows the beans to dry enough so they are not wet when released into the cooler.
Discharging and Cooling &#; Just before the drying process ends, the cooler/destoning fan along with the stirrer will start. This closes a flap in the duct work causing air to be pulled up, or down through the cooling tray. At this time, the roaster will open the discharge door to release the beans into the cooling tray. The stirrer motor helps move the beans from the roaster door. The cooling air is often sent through an abatement system for a period after cooling begins, then switches to exhaust into the atmosphere when the beans have stopped smoking. This begins the cooling process; the stirrer moves the coffee away from the discharge door and distributes the coffee evenly over the cooling tray. In addition, the stirrer continually moves the beans around, so they all get cooled evenly. Some roasters can adjust the amount of time the stirrer stays on during the cooling process (also set through a parameter). This helps to reduce breakage for darker roast profiles. How long the total cooling process takes is adjustable to ensure the coffee is cooled enough for destoning or other transport.
Destoning &#; This process is relatively simple but can cause increased bean breakage if not setup correctly. This step switches an air flap causing the cooling/destoning fan to draw a vacuum into the destoner bin. Dual Fan systems are also which uses separate fans for the cooling and destoning process. Once the destoning system has started, the cooling tray discharge opens allowing the beans to drop into the destoner boot, the stirrer is designed to push the beans to the chute to clean it out completely. The bottom of the destoner boot is what allows the air to be pulled up into the destoner creating a vacuum. The beans, which are now much lighter than they were when they are green get sucked up into the destoner hopper. Because the beans are lighter any stones that were in the mix will fall to the bottom of the boot into a removable tray so they can be discarded. The speed at which the beans are pulled into the destoner hopper depends on how much vacuum is created. It is important that this be checked as too high of speed will cause the beans to break when entering the destoner. Some roasters use VFD (variable frequency drive), and the fan speed is adjustable, other systems have manual gates and flaps on the destoner to allow more fresh air in thereby reducing the vacuum. Finally, once the destoning time has completed, the cooling tray flap is closed and the destoning fan has stopped, the last step in the industrial coffee roasting process is to get an accurate weight of the roasted beans. This weight is added to the batch report along with all the other data from the roast and stored into the historical batch files, and or transferred along with the batch to a Handling system.
While this is a simple overview of the industrial coffee roasting process, it helps to understand what is going on after you press the Charge Button. The roaster has several more tasks it handles while roasting which were not discussed, the most important of which is ensuring both a good roast, but also a safe roast. Monitoring temperatures along with gas and water pressure, along with the monitoring of CO levels, chaff removal systems, bean handling interaction, inline bean moisture analyzers, and automatic samplers are all essential for both roast quality and safety.
