What is Coffee Roasting?
But we need to start with what roasting is, and more importantly why it matters, before getting into the minutiae of equipment. Roasting Coffee is the process of cooking raw coffee cherry beans to turn them brown. Roasting triggers a number of chemical reactions in the beans, which caramelize their natural sugars and also unlock the oils that give coffee its rich flavor.
Roasting is equal parts science and art. To turn coffee from a green seed into the complex drink you and I love, roasters must keep an accurate eye on temperature, time and airflow to get us not only a light roast with bright florals but also dark roast richness. To achieve this precision, coffee roasting equipment becomes essential.
Coffee Roaster Equipment Varieties
The equipment you use for roasting coffee will have an impact on how the process is carried out overall as well as the quality of your final product. There are several kinds of roosters to choose from, all falling under a different mix of capability and design suited to a practical choice on just how much weight or what design you wish to be roasted at the same time.
- Drum Roasters
There are drum roasters, the most common and a style used on both commercial and home equipment. They operate by rotating a cylindrical drum which tumbles the beans, ensuring they are exposed to heat equally. It is favored by Home Roasters who would like to have full control over Temperature and Roast timing.
Advantages:
The rotating drum ensures uniform roasting.
Roast more in a single pass.
Excellent heat retention.
Disadvantages:
Might have a steeper learning curve to learn fully.
Slowish cool down process (to be expected with most smaller roasters).
- Air Roasters (also identified as Fluid Bed Roasters)
Air Roasters / Fluid Bed Roasters:start by circulating the hot air to roast the coffee beans. In these machines, a fan blows air through the roasting chamber and up into the beans as it spins them rapidly, all while keeping them cool. Two very good reasons are because these roasters roast quickly and they do roast evenly.
Advantages:
Faster roasting times.
Easier to clean and maintain.
On the lower end of scorching beans.
Disadvantages:
Traditional Roasting Not Good For Large Batch. Traditional Roasters are Acceptable for Smaller Batches
Noisier, prone to increased airflow.
- Hybrid Roasters
Hybrid Roasters that are a blend between Drum and Air roasting. They also generally make a more bespoke roasting experience, enabling you to fuss with airflow and heat settings to achieve specific roast profiles.
Advantages:
Increased precision in the roast process.
Works well for most roast styles.
Disadvantages:
More expensive, more complex
Takes some practice to use it properly.
- Sample Roasters
Sample Roasters Best tool for small lots to perform lab tests before you commit to a larger roast batch. These machines are usually smaller and meant for roasting only a few ounces of beans at a time, making them perfect for cafes and roasters who want to sample new beans or roast profiles.
Advantages:
Great for proof of concept, and experimental work.
Compact and easy to store.
Disadvantages:
Restricted to small batch roasting.
Not good for every day large need roasting
Key Features to Look For In Coffee Roaster Equipment
If you are serious about roasting coffee than choosing the right coffee roaster equipment is one of the most important decisions you will ever have to make. So here are many of the important factors to consider:
- Batch Size
The biggest factor when purchasing a coffee roaster is the capacity of the roast, or batch size. If you plan to roast more at a time, then consider buying larger equipment. If you’re just roasting for yourself, a smaller machine might work. You can always buy a machine which makes smaller batches if it is for household use, or to save on space.
- Control Settings
Today’s coffee roasters provide a variety of controls which may be tailored through viewpoints as airflow, temperature, and roast time. These settings provide enough flexibility for experienced roasters to dial in the perfect roast. For starters, machines with simpler controls are ideal so that they can understand more about the process of roasting.
- Heat Source
One of the mos important elements within the roaster is probably the heat source, which will determine the way you roast your beans. Gas Roasters: The vast majority of commercial roasters use gas as the main heat source, which provides more control and a more consistent profile. On the other hand, the electric roasters are considered easy to use which is why you will find more of these in homes for domestic uses.
- Cooling Mechanism
Coffee beans, once roasted, require rapid cooling to prevent over-roasting or scorching. Most roasters have integrated cooling trays or fans to speed this part of the process along. However, with roasting coffee, cooling the beans quickly is critical to preserve bean quality and create a more repeatable roast.
- Data Logging
Data logging is a necessary function if you are running your roaster for the purpose of duplicating a changing roast profile. When you register temperature, time and airflow throughout the roasting process, you can either produce identical batches to perfection or replicate better settings for your next roast.
Necessary Coffee Roasting Accessories
Alongside the roaster, there are a few accessories that can make your life easier and yield better results in roasting.
- Coffee Grinders
If you mean to do any real coffee roasting, a decent-grade grinder is almost essential. Grinding your beans fresh has a huge impact on the flavor of your roast.

Green beans are also a vegetable, not fruit so if you hold it over a long period and extremes of temperature and humidity and light as well to ensure that it is always fresh. Storing Beans Airtight Containers, UV Protection is Best Keep your beans in a clean airtight container until you roast them.
- Roasting Thermometer
You can invest in a roasting thermometer that will allow you to check the inner temperature of your roaster. Small changes in temperature can lower the amount at which you can roast a coffee so having a consistent thermometer means that using the 51g is a lot more fool proof.
- Roast Logging Software
While many of the newer behmor roasters come with data logging, if your machine doesnt have this you might also benefit from roast logue software. — which includes the ability to monitor and store roast profiles, so you can repeat what worked or alter parameters on the next go.
