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.

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.

[ What is claimed is:] [1.] In a dosifying system for making a batch of mixed liquid product from separate bulk sources of supply of a liquid carrier and an additive, the improvement comprising:a tubular chamber having an inlet and an outlet;means for delivering the liquid carrier to the inlet of the chamber in a stream;mechanism for incrementally delivering a measured quantity of the additive to the inlet in a metered flow for combining an additive flow and the carrier stream in the chamber to produce the product;a discharge pump coupled with the outlet of the chamber for drawing product out of the chamber as the liquid stream and additive flow are combined within the chamber:a delivery conduit coupled with the pump in downstream relation to the chamber for receiving product from the pump and directing the product to a point of delivery; andmeans for agitating said chamber as the stream of liquid carrier and additive flow are combined in the chamber.
