A biomass burner includes a hopper, a ventilating chamber, a U-shaped fire box, a feeding cylinder including an output end, an auger, a feeding motor including a driving wheel, an ignition device, an ignition motor, a ventilation plate, a first poking device, a second poking device, a first poking motor configured to drive the first poking device, a second poking motor configured to drive the second poking device, a first fixed plate, and a second fixed plate. The hopper is disposed below the feeding cylinder. The feeding cylinder is disposed through the ventilating chamber and the output end of the feeding cylinder extends into the U-shaped fire box. The auger is disposed in the feeding cylinder and is driven by the feeding motor; one end of the auger is provided with a driven gear, and the driven gear is meshed with the driving wheel of the feeding motor.

The present disclosure relates to a tobacco flavoring machine, comprising: a drum (1) capable of rotating about an axis thereof as a rotation center; a nozzle (6) disposed in the drum (1) to spray a liquid flavor to tobacco shreds in the drum (1); and a shoveling plate (5) arranged on an inner wall (11) of the drum (1) and extending from an inlet end of the drum (1) towards the interior of the drum (1), the shoveling plate (5) being disposed obliquely with respect to a generatrix (9) of the drum (1). The present disclosure improves the problem of the related art that tobacco shreds cannot flow smoothly from an inlet end toward an outlet end because a shoveling plate (5) is parallel to an axis of a drum (1).

A method is provided for processing at least two starting materials into a final processed product where a predetermined moisture interval is provided for each starting material. The method comprises subdividing each moisture interval into two or more moisture classes and measuring a moisture content for each starting material prior to processing. Each starting material is then assigned to one of the two or more moisture classes and processed depending on the assigned moisture class. A moisture measurement of the final processed product is determined and one or more processing steps are adapted based on the measuring results for the final processed product to achieve a homogeneous moisture distribution in the final processed product.
