ROASTING FLEXIBILITY AND THE CONVECTION IN OPUS LINE

In the quest for an ideal roaster, the Opus line emerges as a standout solution. It represents the epitome of roaster design, being the only drum roaster that encompasses 100% convective heat transfer. This unique roaster is equipped to handle rapid roasts, completing a full batch in less than seven minutes, as well as long roasts lasting more than 15 minutes, enabling exploration of flavor nuances that generic convective roasters cannot replicate. Lilla roasters, including the Opus line, offer unparalleled flexibility, allowing for precise control of heat transfer and mitigating fire risks through mechanical bean movement within the drum.

While drum chambers can be a significant investment, given the need for costly components such as thicker insulation walls, complex paddles, heavy cast iron rings, and intensive workmanship, their unique blend of high airflow, consistency, flexibility, and performance makes them indispensable in the coffee roasting industry.

OPTIMIZING ROASTING FOR SOLUBLE COFFEE INDUSTRIES

Soluble coffee production often involves a diverse range of beans, including small or broken ones. Traditional drum roasters, which primarily employ conduction heat transfer, are not suited for scenarios where small or broken beans are mixed with regular ones, as they carry a higher risk of fire.

Conversely, fluidized bed roasters, despite their high airflow rates, struggle to safely roast a mix of diverse beans. Small beans tend to dry and roast faster than their larger counterparts, leading to inconsistencies and risks. Regardless of whether the roaster uses conduction or convection for heat transfer, it's essential to recognize that within the bean, heat is exchanged through conduction.

Thus, for lower-grade coffees, such as that commonly found in the instant coffee industry, a convective-based roaster is preferred, capable of a range flexible of RoR to address a wide range of beans from a non-uniformity raw material with defects to a uniform high quality coffee.

REDUCING LOSSES AND ENHANCING EFFICIENCY

Lilla roasters distinguish themselves by effectively retaining small beans within the chamber and also preserving them by a gentle care of convection, thereby minimizing roasting losses. Moreover, the use of a drum in convective roasters significantly reduces the electrical energy required to agitate the beans, as opposed to other convective roasters that demand high-power fans. In an era where energy efficiency is paramount, this characteristic is a distinct advantage.

The Opus 4000, for instance, demands 11.5 kWh/ton of electrical energy, while fluidized bed roasters require a minimum of 25 kWh/ton and, in many cases, exceed 35 kWh/ton. In terms of thermal energy, Opus 4000 roasters have been delivering at the nominal production a consumption varying from 305 kWh/ton up to 335 kWh/ton, depending on the coffee and the final roasting color. All these values are achieved with full smoke elimination, regardless of the emission standards, with or without a catalyst system.

THE OPUS LINE: PREFERRED BY LEADING INSTANT COFFEE PLAYERS

As global dynamics shift, the Opus line has gained popularity among key players in the instant coffee market. Its flexibility, remarkable thermal and electrical energy efficiency, minimal roasting losses, and impressive extraction of soluble solids make it the roaster of choice for those seeking excellence in the coffee industry.

In the intricate world of coffee roasting, roaster design emerges as a crucial catalyst, orchestrating a symphony of flavor, quality, and efficiency, with Lilla delivering remarkable results.
