LORING S70 PEREGRINE: Smokeless, Smart Coffee Roasting
Coffee roasters have long wrestled with two stubborn problems: inconsistent roast results and the headaches—and hazards—of smoke and chaff. Traditional roasters demand constant adjustments for weather, venting, and cleaning, often sacrificing flavor for manageability. If you've ever dealt with greasy smoke stacks, fire risks from built-up chaff, or inconsistent batches due to environmental swings, you know how much these issues impact both safety and cup quality.
The LORING S70 PEREGRINE solves both major pain points in one system: it offers a fully enclosed, smokeless roast with 80% lower energy use and perfect repeatability—every time.
What Makes the LORING S70 PEREGRINE Different?
The LORING S70 PEREGRINE isn’t just another roaster. It’s built around the patented Flavor-Lock Roast Process™, a closed-loop system that removes oxygen from the roasting chamber while adding moisture-rich heat. That means no smoke, no oxygen degradation of beans, and a cleaner, more stable roast environment. The result? More yield, better flavor, and zero emissions.
How It Works: Closed-Loop Roasting & Smart Design
The secret lies in its Flavor-Lock Roast Process™ technology. Here’s how it breaks down:
- Smokeless Roasting: A single-burner design with a computer-controlled, oxygen-free closed loop eliminates visible smoke entirely.
- Zero Emissions: Chaff and silverskin are separated, burned cleanly, and never released. Smoke is converted into water vapor and recycled back into the roast chamber.
- Closed-Loop Heat System: The roaster recirculates heated air internally—only minimal excess warm air exits through the exhaust. No oily, sticky buildup in exhaust stacks means no fire risk.
- Environmentally Stable: Weather, humidity, and ambient temperature don’t affect roast consistency—because the chamber is sealed off from external air changes.
- Energy Efficient: Uses up to 80% less gas than traditional roasters. In the U.S., that equates to saving around $30,000 annually on gas per machine.

Frequently Asked Questions
What makes the LORING S70 PEREGRINE truly smokeless?
The Flavor-Lock Roast Process™ creates a closed-loop system where oxygen is removed and replaced with moisture-rich heat. Chaff and silverskin are burned inside a separate combustion chamber, and any residual smoke is turned into water vapor that cycles back into the roast chamber. Only minimal warm air exits, resulting in no visible smoke and a much cleaner roasting environment.
How much energy does the LORING S70 save compared to conventional roasters?
It uses up to 80% less gas. For example, in the U.S. market, a roastery can save approximately $30,000 per year on gas bills by switching to the LORING S70.
What batch sizes can the LORING S70 handle?

The maximum batch size is 70 kg (154 lb), and it can roast as little as 15 kg (33 lb) per batch. That flexibility makes it suitable for both small-batch and high-volume specialty roasters.
Does the LORING S70 require a lot of maintenance?
No. Its self-cleaning exhaust stack prevents chaff buildup and stack fires. The roaster also features low-maintenance motors, automatic cooling systems, and minimal external exhaust, which reduces the need for frequent cleaning or upkeep.
Can the LORING S70 be controlled remotely?
Yes. The machine connects to the internet, allowing manufacturers to provide remote diagnostics and support. Roasters can also operate and monitor the machine online using the touchscreen or optional iPad connectivity.
Is the LORING S70 affected by seasonal weather changes?
No. Because it uses a closed-loop airflow system that doesn’t rely on ambient air, the roast environment remains consistent regardless of external temperature or humidity fluctuations throughout the year.
