LORING S70 PEREGRINE: The Smart Coffee Roaster Redefining Consistency

If you’ve ever struggled with unpredictable roast profiles, smoke-filled roasting spaces, or the constant hassle of cleaning clogged vents, you’re not alone. Traditional coffee roasters present persistent challenges: inconsistent heat control, oxygen exposure that degrades flavor, and dangerous buildup in exhaust systems. These aren’t minor inconveniences—they directly affect the quality, safety, and repeatability of every batch.

The LORING S70 PEREGRINE addresses both the biggest pain points in coffee roasting: precise process control and smoke elimination. Its patented Flavor-Lock Roast Process creates a closed-loop system that removes oxygen while maintaining ideal humidity, resulting in better-tasting, higher-yield roasts. Plus, it’s virtually smoke-free and 80% more energy-efficient than conventional machines.

What Makes the LORING S70 PEREGRINE Different?

The LORING S70 PEREGRINE isn’t just another roaster—it’s built around a patented smart roasting technology called the Flavor-Lock Roast Process™. This closed-loop system removes oxygen from the roasting chamber while increasing humidity in the heating gases. The result? More consistent roasts, better retention of aromatic compounds, and significantly improved cup quality. The machine also integrates a unique chaff and dust separation system that incinerates the silver skin (chaff) and converts smoke into water vapor, feeding it back into the roast chamber. This closed thermal circuit ensures no smoke escapes, no oxygen enters, and energy loss is minimal.

Why Is Smoke and Oxygen Such a Problem in Roasting?

Traditional roasters vent smoke and hot air through external chimneys, which leads to several issues:

• Fire hazard: Accumulated chaff and oils in exhaust ducts can ignite if not cleaned regularly.
• Oxidation: Exposure to oxygen during roasting degrades aromatics and shortens flavor stability.
• Energy waste: A large portion of heat is simply expelled outdoors, raising operational costs.
• Environmental impact: Emissions from burning chaff and smoke contribute unnecessarily to pollution.

LORING eliminates all these problems. Its closed-loop system means no smoke is released, the chaff is fully incinerated, and no external venting of dirty air is required. The absence of an open chimney also means no soot buildup and no fire risk. And because the machine recycles heat and moisture, it uses up to 80% less energy compared to traditional roasters. According to manufacturer estimates based on U.S. data, a roastery could save $30,000 annually just on gas bills by switching to LORING.

How Does the LORING S70 PEREGRINE Ensure Consistent Roasts?

The secret is in the closed thermal environment. By removing oxygen and controlling humidity, the Flavor-Lock system creates ideal conditions for the Maillard reaction and development phase. Unlike conventional roasters affected by ambient temperature and humidity shifts, the LORING maintains identical roast conditions year-round. That means a light Ethiopian Yirgacheffe roasted in summer will taste just as vibrant and balanced as one roasted in winter.

Every variable is digitally managed via an intuitive touchscreen interface, allowing roasters to program, monitor, and replicate roast profiles minute-by-minute. The machine logs every batch, making it easy to reproduce results consistently. And because it’s internet-connected, LORING’s support team can remotely diagnose issues or offer guidance—while users can also control and monitor their roasts off-site.

Frequently Asked Questions

What is the Flavor-Lock Roast Process™ in the LORING S70 PEREGRINE?

The Flavor-Lock Roast Process™ is LORING’s patented closed-loop roasting system that removes oxygen from the roast chamber while increasing humidity in the heating air. This creates optimal conditions for flavor development, minimizes oxidation, and prevents the degradation of aromatic compounds during roasting.

Does the LORING S70 PEREGRINE produce any smoke during roasting?

No, the LORING S70 PEREGRINE is designed to be a no-smoke roaster. It converts smoke into water vapor and recirculates it back into the roast chamber, while also incinerating chaff internally. No smoke is released externally, eliminating the need for external venting.

How much energy does the LORING S70 PEREGRINE save compared to traditional roasters?

The LORING S70 PEREGRINE is up to 80% more energy-efficient than conventional coffee roasters. Based on U.S. usage data, a roastery can save approximately $30,000 per year on gas expenses by using this machine.

How does the LORING S70 PEREGRINE handle chaff and smoke?

The machine features a unique chaff and smoke separation system. Silver skin (chaff) is fully incinerated internally, keeping the collector clean and reducing fire risk. Smoke is converted into high-temperature water vapor, which is recycled back into the roast chamber instead of being vented outside.

Can the LORING S70 PEREGRINE roast consistently in different climates?

Yes. Because it uses a closed-loop thermal system that controls humidity and excludes external air, the LORING S70 PEREGRINE produces consistent roast profiles regardless of seasonal or environmental changes in temperature and humidity.

Is the LORING S70 PEREGRINE internet-connected?

Yes. Every LORING roaster can connect to the internet, enabling remote monitoring, troubleshooting, and support from the manufacturer. Users can also operate and manage their roasts remotely via online access.
