Abstract
A meter for controlling the flow of feedstock from an in-feed hopper to a distillation unit, including a cylindrical roller having a first end, a second end, and an outer diameter, the roller defining a recess that extends helically substantially from the first end to the second end, a sleeve circumscribing a portion of the outer diameter of the cylindrical roller, the sleeve having an open first side that allows the passage of feedstock into the recess of the roller, and an open second side that allows the passage of feedstock out of the recess of the roller as the roller rotates relative to the sleeve, and a housing fixedly attached to the sleeve and capable of attachment to the in-feed hopper and the distillation unit such that feedstock must pass through the housing to get from the in-feed hopper to the distillation unit.
