1. Drum Roasting
Drum roasting’s been around since the 1880s. It uses a spinning metal drum heated by gas or electricity. Here’s what you need to know:
Setup Costs
Drum roasters aren’t cheap:
| Roaster Type | Price Range |
|---|---|
| Small-scale | $1,000 – $6,000 |
| Commercial | $20,000 – $150,000 |
The Sandbox Smart R2 Coffee Roaster can handle up to 550 grams of beans at once.
Energy Use
Drum roasters use more energy than air roasters. But some, like the Loring, are more efficient:
"The Loring roaster uses about 1/4 of the gas per pound of roasted coffee compared to other machines, saving around $500 in natural gas costs yearly." – Archipelago, Coffee Roaster
Labor and Maintenance
Drum roasters need constant attention:
- Operators must stir beans
- Roasting takes 15-20 minutes per batch
- Regular cleaning is a must
Doug Graf from Vintage Coffee says, "Good maintenance is key for good coffee."
Yield and Quality
Drum roasters can be efficient:
- Light roast loss on a Probat: 13.7-14.5%
- Light roast loss on a Loring: 11-11.5%
They’re known for rich, full-bodied coffee. But watch out for scorching.
2. Fluid Bed Roasting
Fluid bed roasting uses hot air to move coffee beans. It’s a different approach to cost-effective roasting:
Setup Costs
Fluid bed roasters are cheaper:
| Roaster Type | Price Range |
|---|---|
| Small-scale | $300 – $3,000 |
| Commercial | $20,000 – $50,000 |
Energy and Time
They run on electricity and roast faster:
- Roasting time: 6-8 minutes per batch
- Less manual work needed
- Easier to clean and maintain
Ken Lathrop, owner of Coffee Crafters, says: "One big advantage is simplicity."
Quality and Efficiency
Fluid bed roasting is efficient:
- Faster roasting means higher daily output
- More consistent results
- Better automation and precision
It produces a different flavor:
- Cleaner, brighter taste
- More even heat distribution
Tim Monson from The Monsoon Roastery shares: "It was closer to how I started with a popcorn popper."

3. New Roasting Methods
Coffee roasting’s changing. New methods aim to cut costs and boost quality:
Air Roasting
Uses hot air to move and heat beans:
- Even roasting
- Clean taste
- Quick process
Infrared Roasting
Heats beans directly:
| Feature | Benefit |
|---|---|
| Fast heating | Shorter roast times |
| Uniform roasting | Consistent quality |
| Low acid | Easier on stomachs |
Sandy Toomer from Toomer’s Coffee says: "Infrared roasting is superior. Period."
Electric Roasting
More roasters are going electric:
- Lower carbon footprint
- Easier setup
- Can use renewable energy
Grayson Caldwell from Bellwether Coffee notes: "The industry’s recognizing gas roasting’s environmental impact."
Induction Roasting
The AiO roaster uses this tech:
- 75% energy savings
- Smaller size
- More automation
Jonas Lillie, CEO of Aillio, explains: "Future focus will be on savings through tech."
Good and Bad Points
Each method has pros and cons:
| Method | Pros | Cons |
|---|---|---|
| Drum | Better control, handles various sizes | Longer roasts, higher energy use |
| Fluid Bed | Faster, even roasting, quieter | Limited batch size, less control |
| Air | Even roasting, clean taste, quick | Limited batch size |
| Infrared | Fast heating, uniform roasting | Limited adoption, new equipment needed |
Consider your budget, quality needs, batch size, energy efficiency, and space when choosing.
Wrap-up
Different methods suit different businesses:
| Method | Best For | Cost Notes |
|---|---|---|
| Drum | Large operations | Higher upfront cost, energy-intensive |
| Fluid Bed | Small to medium businesses | Lower initial cost, faster roasting |
| Air | Home roasters, small businesses | Energy-efficient, limited batches |
| Infrared | Specialty roasters | Fast heating, new equipment needed |
To manage costs:
- Try "contract roasting" to start
- Roast off-peak to save on utilities
- Invest in energy-efficient roasters
Jonas Lillie from Aillio says: "Roasting doesn’t have to be hard. There’s lots of info to help you start."
Pick the method that fits your size, location, and needs to balance quality and cost.
