Abstract
To continuously mix two flowable products such as a solid product in the divided state and a liquid product, two concentric ducts are provided each with associated entraining means. The entraining means of the outer duct serves to move a first one of the flowable products along the duct from an entry port towards an exit port for the mixed products and includes a helical element urging the first product into rotation in passage along the outer duct. The second duct opens into the outer duct between the entry and exit ports of that duct and the entraining means of the inner duct serves to move the second flowable product through the inner duct and into the outer duct in the center of the first product stream.

Apparatus for continuously mixing two flowable products, the apparatus comprising a first duct having an entry port through which a first flowable product stream can pass into the first duct and an exit port through which the mixed flowable products can pass out of the first duct, first entraining means provided with a helical element and serving to impart helical motion to the first flowable product stream within the first duct, a second duct concentrically mounted within the first duct and provided with an entry port through which a second flowable product stream can pass into the second duct, the second duct being arranged to open into the first duct between the said entry and exit ports thereof to allow said second stream to pass into the first duct, and second entraining means serving to move said second flowable product stream along the second duct, the first and second entraining means being distinct from each other and serving to move the product streams in the same direction.
Apparatus for continuously mixing liquid products with solid products in the divided state, the apparatus comprising at least two concentric ducts the outermost one of which is provided with an entry port through which a first product stream can pass into the duct and an exit port through which mixed products can pass out of the duct, the outermost duct being further provided with helical entraining means for urging into rotation the first product stream in passage along the duct, the or each inner duct being of smaller cross-section than the outermost duct and being provided with entraining means for moving a second product stream therealong, the or each inner duct extending into the outermost duct and opening therewithin downstream of its entry port and upstream of its exit port, the said entraining means being distinct from each other and acting on the products in the same direction.
