Method and means of controlling a food extruder as a function of bulk density of the extruded product

摘要

A bulk density sampling method and device whereby formed product is flowed through a vertically disposed passage of pre-determined size. The passage is temporarily obstructed to collect and weigh a known volume of product upon which to base a calculation of bulk density and the generation of a control signal for regulating a multi-tasking processor to constantly monitor, control, and display speed, head gap position, temperature, feed rate and target moisture.
