Why should you consider a fully electric roaster? First, there is a global shift in regulations and building codes that favor electric heat sources in appliances. This means that using an electric roaster ensures compliance with these changing specifications in commercial real estate construction. Second, we consider electric burners cleaner and more efficient than traditional fossil fuel burners. Electric roasters produce low emissions, including less carbon monoxide (CO), carbon dioxide (CO2), and nitrogen oxides (NOx), which are harmful gases released during the combustion of fossil fuels. This makes electric roasters a more environmentally friendly choice.
Challenges with gas-powered machines
Traditionally, we roast coffee using gas-powered machines, which presents several challenges. Gas roasters require a constant supply of fuel, potentially increasing operational costs and environmental impact. Additionally, maintaining a consistent temperature throughout the roasting process can be challenging, possibly leading to inconsistent flavors in the final product.
Advantages of roasting on electricity
Electrically heated coffee roasters manufactured by Giesen address these issues by utilizing electricity as the primary heat source. This eliminates the need for gas and provides a more sustainable roasting solution. By using electricity, coffee roasters can harness precise temperature control, ensuring a consistent roast profile for every batch. Another advantage of Giesen’s fully electric roasters is their energy efficiency. This not only benefits the environment but also translates into cost savings for coffee roasters. With rising energy prices, these innovative roasting machines potentially offer a more economical solution, making them an attractive option for small-scale coffee roasting businesses.
The innovative electric heating system
The IR heating panels, which are conductive, provide a more precise and efficient way of heating the beans, specifically during the drying phase and the subsequent Maillard reactions. The IR panels emit infrared radiation that conducts heat to the coffee beans, resulting in a more even and controlled roast. The hot air blower, on the other hand, generates convection heat. Hot air circulates throughout the roasting chamber, ensuring that the beans are evenly exposed to the heat. This combination of conduction through the IR panels and convection through the hot air blower creates a synergistic effect, enhancing the chemistry transformation of the coffee beans during the roasting process. By utilizing this advanced dual heating system, Giesen’s electric roasters offer a level of control and precision that was previously unattainable.
We can conclude that Giesen has successfully addressed the challenges associated with electric roasting machines. Models, like the W6E and W15E, use innovative heating systems. The W6E initially utilized heating coils, while the brand-new generation of W15E roasting machines incorporates a combination of infrared (IR) heating panels and a hot air blower. The IR heating panels provide conductive heat, while the hot air blower ensures efficient convection.
Cost-effectiveness and installation
What makes Giesen’s electric roasters extra appealing is the reduced cost of the installation of these machines. This compared to other brands of roasters, provided that the roasting facility has sufficient electrical capacity. The reinvention of electric roasting machines is a testament to Giesen’s commitment to innovation. By designing a sophisticated heating system for the W15E, which combines IR panels and an efficient hot air blower, Giesen has created a highly efficient and effective roasting machine. These advancements in electric roasting technology are changing the game for coffee roasters, offering a more sustainable and cost-efficient solution.
We are at the forefront of the revolution in electrically heated coffee roasters. Offering a range of innovative and environmentally friendly solutions for the coffee industry. By embracing fully electric roasters, businesses can comply with changing regulations, reduce harmful emissions, and benefit from improved temperature control for a consistent roast profile. Giesen’s advanced electric roasting system, incorporating infrared heating panels and a hot air blower, sets new standards for precision and efficiency in the roasting process. Moreover, the cost-effectiveness and reduced installation expenses make these electric roasters an attractive option for both large-scale commercial roasters and smaller coffee roasting businesses. With their unwavering commitment to innovation, Giesen has paved the way for a more sustainable and economically viable future for coffee roasters worldwide.
