Modified filter rod feeding trays for porous masses

A modified feeding tray comprising:

• a rectangular bottom;
• opposing first and second sidewalls coupled to corresponding first and second edges of the rectangular bottom;
• a third sidewall coupled to a third edge of the rectangular bottom and extending between the first and second sidewalls;
• a shelf extending from the first sidewall to the second sidewall at an intermediate location along a length of each of the first and second sidewalls and thereby defining an open compartment formed by the first and second sidewalls, the shelf, and the bottom, and a closed compartment defined by the first, second, and third sidewalls, the shelf, and the bottom;
• a support within the closed compartment that operably connects to and extends from the bottom along at least a portion of a depth of the shelf;
• and
• an elongated slot in the bottom corresponding to the support such that the support is moveably coupled to the bottom along the elongated slot using one or more mechanical fasteners.
