Thermal Efficiency and the extraordinoray RoR<\/strong><\/h2>\n\n\n\nA common coffee roaster mainly relies on heating the drum and air to roast coffee beans, resulting in a lot of heat loss. The roasting environment temperature will rise, and gas roasters are easily affected by weather factors. In contrast, a traditional electric roaster can only achieve a maximum heating rate of 10\u00b0C\/minute by roasting a full pot.
Rubasse near-infrared radiation is released from the center of the drum, and the heating source will a. <\/strong>Directly heat up the coffee beans, b.<\/strong> Reflect and then heat the coffee beans, c.<\/strong> Heat the drum wall, d.<\/strong> heat the air inside the drum, forming a optical cavity that continuously converts inside the drum. According to the second law of thermodynamics<\/strong>, all the heat sources will eventually transfer to the lower-temperature coffee beans. This resonance structure<\/strong> allows Rubasse to achieve ultra-high thermal efficiency. Roasting a full 3kg batch, the maximum RoR<\/strong> (rate of riase) can reach 25\u00b0C\/minute.<\/p>\n\n\n\n

Stability and controllability of the heat source.<\/strong><\/h2>\n\n\n\nA typical gas coffee roaster can only control the heat source by regulating the gas flow. However, the purity of gas, the proportion of propane and butane, the oxygen content in the environment, the completeness of combustion, the humidity and the atmospheric pressure in the environment cannot be precisely controlled, and indirect roasting of coffee beans through heating the boiler not only wastes energy but also makes it difficult to control the coffee roasting process.
Rubasse near-infrared heat source design only requires controlling the electrical power to control the heat source. The heating halogen is located at the axis of the drum, and the radiant heat directly heats up the coffee beans, allowing for very precise control of the heat output.<\/p>\n\n\n\n
\n\n\n\nSafety of the heat source.<\/strong><\/h2>\n\n\n\nConventional gas roasters use gas as fuel and can pose risks such as incomplete gas combustion, carbon monoxide poisoning, gas explosions, and flash fires in poor roasting environments with excessive dust. In contrast, the Rubasse coffee roaster uses electricity as its heat source, eliminating the risk of gas-related safety issues and any open flames<\/p>","protected":false},"excerpt":{"rendered":"
