IMPROVED FLAPPER ASSEMBLY FOR PRODUCING A CURLY PUFF EXTRUDATE |
摘要 |
In the process of forming a curly puff extrudate (20), an improved method of applying a controlled pressure to the flapper (32, 82) of the extrusion apparatus is performed using a penumatic system. A rotary actuator (80) applies a near constant pressure to the flapper (32, 82). Alternatively, a pair of telescoping tubes connected to the flapper (32, 82) and an air pressure source can apply a near constant pressure to either the proximate or distal end of the flapper (32, 82). Further in the alternative, a linear actuator can be used to provide a near constant pressure to the flapper (32, 82). As a result of the applied pressure to the flapper (32, 82), the pitch in the curls of the curly puff extrudate (20) can be more predictably controlled. |
