The advantages of semi-hot air heating commercial baking machines are mainly reflected in the following aspects:
Stable temperature control: The heat of the semi-hot air baking machine is relatively stable and is less affected by the external environment. During the baking process, simply adjusting the heat can easily control the required heat for each baking stage, thus ensuring the stability and controllability of the baking temperature.
High uniformity of roasting: The semi-hot air roaster introduces heat energy into the interior of the drum through the deflector holes on the inner side of the drum and evenly transfers heat through the metal, making the roasting of coffee beans more uniform. Compared with direct-fire roasters, under the same roasting degree, the difference between the surface and core of coffee beans roasted by semi-hot air roasters is smaller, and the flavor and aroma are relatively more stable.
Semi-hot air roasters are more suitable for roasting blended coffee. When beans of different densities are mixed, the heat energy provided by the semi-hot air machine is more evenly distributed. Even if the densities of the green beans are inconsistent, the heat source provided by the roaster can be fully absorbed by the green beans, thus ensuring the consistency of the quality of the blended coffee.
Higher safety: The semi-hot air roaster has been improved on the basis of the direct fire type. The drum is separated by a partition, so the open flame does not directly contact the coffee beans. Instead, the generated heat enters the drum to roast the coffee beans. This design reduces potential safety hazards such as fires and enhances the safety of the baking process.
Easy to operate: The operation of the semi-hot air baking machine is relatively simple and easy to get started with. For beginners, through learning and practice, they can quickly master the operation skills of semi-hot air roasters and achieve uniform roasting and flavor control of coffee beans.
