AI Technical Summary
In existing coffee roasting machines, some coffee beans are exposed to high temperatures for extended periods during roasting, resulting in excessive caramelization and a bitter, burnt taste. Meanwhile, some beans are under-heated, leading to uneven roasting levels and inconsistent flavors throughout the batch, which negatively impacts the taste and quality stability of the final coffee product.
By setting up a feeding mechanism and a heating mechanism, and designing a turntable and stirring rod structure, the coffee beans are fed and stirred evenly, ensuring that each bean receives a similar heating time and environment in the roasting chamber, avoiding local stagnation and breaking the static accumulation state.
This process ensures uniform roasting of coffee beans, avoids uneven flavor due to differences in heating, and improves the consistency of the taste and quality of the finished coffee product.
