Which of the following operational parameters govern the separation of broken and weed seeds from whole grain in an indented cylinder separator?
Options:
(A) Rotational speed of the horizontal indented cylinder
(B) Tilt angle and height adjustment of the internal collection trough
(C) Depth, diameter, and shape profile of the stamped surface indentations
(D) Dielectric breakdown voltage of the grain seed coat
Answer Key:
A, B, C
Step-by-Step Solution & Explanation
Indented cylinder length separators lift shorter particles that fit snugly inside the indentations up to a higher angle of rotation before centrifugal and gravitational forces drop them into the internal trough. Cylinder speed (A), trough lip position (B), and indentation geometry (C) directly determine the cut point. Dielectric properties (D) are irrelevant.
