Mechanism for adjusting an extrusion die in cereal grain extruder apparatus

摘要

Apparatus for producing a curled food product by extruding gelatinous cereal grain meal includes a mechanism for adjusting the extrusion space between two complimentary frustroconically shaped die surfaces of die extrusion members. One die member is maintained in an axially or longitudinally stationary position while the other die member is moved axially or longitudinally with respect to the stationary member. As a result, the space between the complimentary die surfaces may be adjusted to control the cereal grain extrusion process. Adjusting the extrusion die includes longitudinally adjusting a second frustroconically shaped die surface in face-to-face relation with a first complimentary and frustroconicaly shaped die surface in order to adjust the separation space therebetween.
