Apparatus for producing a product such as fertilizer which has acidic and basic constituents having, a venturi pump and a mixing tank. The venturi pump is powered by mixing the constituents in a reaction chamber and expelling the resulting product through a venturi tube. The venturi tube entrains additional product adjacent to the entrance of the tube and expels the additional product along with the product just produced by the reaction in order to mix the product in the tank.

An apparatus for reacting an acid reactant and base reactant and mixing the reaction product with said reactants, whereby the acid and base reactants are reacted and partially neutralized to salts, wherein lumping of the salts is avoided, said apparatus comprising: a mixing tank; and a venturi pump

An apparatus for reacting an acid reactant and base reactant and mixing the reaction product with said reactants, whereby the acid and base reactants are reacted and partially neutralized to salts, wherein lumping of the salts is avoided, said apparatus comprising: a mixing tank; and a venturi pump mounted in said mixing tank and comprising: a venturi tube having inlet and outlet ends; a reactor upstream of said venturi tube and comprising: a reaction chamber having a central wall portion which is cylindrical in cross-section and inlet and outlet ends which are smaller in diameter than the cylindrical portion and joined thereto, respectively, by first and second concave frusto-conical wall sections, said outlet ends of said reaction chamber forming a nozzle projecting into the inlet end of the venturi tube and a plurality of holes in said first concave frusto-conical wall section; and an induction chamber upstream from and adjacent said reaction chamber and overlying at least a portion of the first concave frusto-conical wall section and registering with the holes in the first concave frusto-conical wall section; first inlet means for introducing one of said reactants into said induction chamber, whereby said reactant may pass through the holes in said first concave frusto-conical wall section into said reaction chamber; and second inlet means for introducing the other reactant and the contents from the mixing tank directly into said reaction chamber through the inlet end of said reaction chamber without being introduced into said induction chamber; whereby the reaction between the acid and base reactants may take place in said reaction chamber to release energy which powers said venturi tube by expanding through said outlet end of said reaction chamber into said inlet end of said venturi tube.
