Systems and methods for liquid dosing in blender systems are disclosed. An exemplary system includes one or more individual metering devices, each metering device including an individual material hopper for containing a granular material ingredient to be blended, a starve-fed mixing chamber coupled to the metering devices for receiving granular material ingredients from each metering device and mixing the ingredients, and a liquid ingredient dosing device disposed within the starve-fed mixing chamber for injecting a liquid ingredient into the path of the granular material ingredients as they fall through or out of the mixing chamber.

The present disclosure provides approaches for reducing buildup of particulate-matter in particulate-matter-delivery systems. In some embodiments, a trough-shaped feeder is provided in which a rectangular-to-elliptical conduit extends from the trough-shaped feeder. The trough-shaped feeder has a substantially-rectangular feeder opening. The rectangular-to-elliptical conduit has an elliptical end and a rectangular end. The elliptical end of the rectangular-to-elliptical conduit has a substantially-elliptical conduit opening. Interfacing the storage hopper to the trough-shaped feeder via a elliptical-to-rectangular conduit reduces the particulate-matter-delivery system's susceptibility to bridges and rat holes.

A removable material hopper assembly for gravimetric batch blenders including a hopper, a metering assembly and a releasable securing assembly. The hopper is removable from the blender, and includes a metering slide gate that can be used to tightly seal off the bottom of the hopper during the removable operation. The releasable securing assembly incorporates a tongue and groove subassembly and a pin and bracket subassembly to properly align and secure the hopper to the blender during operation, but also enables easy removal of the hopper when necessary.
