Background technique

Wood pellet ovens have received widespread attention and popularity in the market due to their smoky flavor, but existing products have technical problems that are difficult to overcome in actual use: wood pellet fuel is usually able to generate sufficient energy when burned at relatively low temperatures. The smoke makes the grilled food have an ideal smoky flavor, but grilling food at low temperature requires a long time, which greatly reduces the food processing efficiency. However, if the combustion environment temperature of wood pellet fuel is increased, although it can be achieved to a certain extent The grilling time is shortened, but because the fuel is fully burned, it is difficult to generate enough smoke, and the grilled flavor of the food is not good. At the same time, wood pellets heat up slowly when burning, taking a longer time to reach the temperature that creates a grill mark on the surface of the food (usually about 600 degrees Fahrenheit), and it takes longer for the food to reach its ideal state.

In addition, since wood pellet ovens are generally used in outdoor environments, their performance is greatly affected by weather and temperature. The time required for the oven to reach the target temperature is uncertain, and it is difficult to maintain it within the target temperature range for a long time, which affects the food. of baking quality.
