Air Roasting

There are many reasons to choose a Loring roaster. First and foremost in our mind is the fact that Loring roasters produce beautiful coffees. Loring roasters give us an amazing level of control over the roasting environment, and consequently over the product that emerges from it. The control system allows us to make subtle adjustments to the roasting environment in real time. For example, we are able to increase or decrease the temperature within the roast chamber by one degree increments almost instantaneously.

This allows us to experiment with a level of fine detail that is simply not possible with roasting technologies that uses a flame under a metal drum. The challenge with any traditional drum system is the thermal mass of the drum. You have a massive piece of very hot metal that limits how quickly you can change the temperature in the roast chamber, and also limits how fine those temperature changes can be.

In a Loring there is no flame under the drum. Instead there is a burner at the base of the cyclone. This burner heats the air that circulates through the roast chamber and roasts the beans. The fixed stainless steel drum, which resist absorbing heat, uses a paddle assembly to stir the beans.

Quality

The great advantage for us, that later translates over to our customers, is that by making fine changes to the burner we can get immediate fine changes in temperature (either up or down) within the roasting chamber. So with a Loring we are able to make very quick fine changes to our roast profiles and thus develop all the nuances and subtle flavors in our beans.

Consistency

We believe consistency is a key factor in good coffee.With a traditional system, air is being pulled from outside the roaster while coffee is roasting. As the outside atmosphere changes (temperature, humidity, pressure), adjustments need to be made to the roast profiles to account for those changes and thus ensure consistency.Our Loring employs a closed loop system. Meaning the roast chamber is isolated from the outside atmosphere. Essentially, with every roast the Loring creates its own atmosphere within the roast chamber.The advantage to us is that we always get the exact same roast conditions every time we roast no matter what the weather is like outside the roaster - and this ensures we get the same consistent flavor development with every roast.

Huge energy savings

We believe in a greener earth.

Our Loring roaster IS the most environmentally friendly roaster available. We reduce energy consumption and greenhouse gas emissions by up to 80% compared to a conventional roaster and afterburner system of the same size. Those energy savings result from two Loring innovations.We don't need an afterburner. Conventional roasters use afterburners to eliminate the smoke produced during roasting. Afterburners typically consume at least 400% more fuel than the roaster itself. Our Loring uses a single pressurized burner to both roast the coffee and incinerate the smoke and odor.

Recycling Energy

We recirculate the heated air. Conventional roasters are constantly pulling outside air into the roast chamber and then need to heat that air from room temperature to roast temperature. Loring's unique technology captures the hot air coming out of the roast chamber, removes the smoke from the air before exhausting it, and recirculates the remaining hot air back into the roast chamber. By using 80% less energy we also reduce CO2 production by 80%.
