ABSTRACT:
A system for applying accurately metered, minute quantities of concentrated additives from bulk sources of supply to successive masses of material presented for treatment includes a pass-through chamber within which separate streams of a liquid carrier and the additive substance are merged together. As the liquid carrier passes through the chamber, the additive, in either dry or liquid form, is likewise directed into the chamber in a metered flow to incrementally combine with the liquid stream and form the combined product. A suction pump at the downstream end of the chamber draws the prepared product out of the chamber and advances it toward an ultimate delivery site. The carrier liquid is prevented from accumulating into a pool within the chamber by the suction pump that cooperates with the upright orientation of the chamber to cause the carrier liquid to swirl smoothly through the chamber. A suction vortex may be created as the product exits the chamber, within which vortex the additive may be directed so as to complete its entrainment with the carrier without causing turbulence. The system can be easily flushed with the liquid carrier after each batch and then dried with an optional air blower.
