1. A system for measuring tobacco for packaging in pouches, the system comprising:
a hopper including a hopper cavity configured to hold a granular material; and
a measuring system including a measuring cavity and a tube that is slidable in the hopper cavity between a first position unaligned with the measuring cavity and a second position over and aligned with the measuring cavity, the measuring system including,
a first valve disposed between a vacuum source and the measuring cavity, the first valve being configured to selectively place the vacuum source in fluid communication with the measuring cavity, and
a second valve disposed between a pressurized gas source and the measuring cavity, the second valve being configured to selectively place the pressurized gas source in fluid communication with the measuring cavity independent of a position of the first valve, wherein the first valve is configured to continuously communicate a vacuum to the measuring cavity,
the measuring system configured to move a portion of the granular material from the hopper cavity to the measuring cavity when the tube is in the first position, and
the measuring system configured to move the portion of the granular material from the measuring cavity, through the tube, to a pouch making machine by operating the second valve to supply pressurized gas that overcomes the vacuum when the tube is in the second position.
