Improved flapper assembly for producing a curly puff extrudate |
摘要 |
An improved method of applying a controlled pressure to the flapper in a curly puff production apparatus. The present invention uses a pneumatic system to apply a pressure to a flapper. The invention utilizes a rotary actuator that applies a near constant pressure to the flapper. Alternatively, a pair of telescoping tubes connected to the flapper and an air pressure source can apply a near constant pressure to either the proximate end or the distal end of the flapper. Further in the alternative, a linear actuator can be used to provide a near constant pressure to the flapper. As a result of applying a constant pressure to the flapper, the pitch in the curls of the curly puff extrudate can be more predictably controlled. |
