Abstract
Mixing systems and methods of making mixed compositions including a first composition and a second composition. The systems and methods incorporate a fluid flow manipulation to manage an undesirable accumulation of a separable ingredient such as particles associated with the first and/or second composition as the mixed composition is further processed and packaged downstream.
Claims22
A method of making a mixed composition, comprising:
- a) providing a mixer comprising a first inlet, a second inlet, an outlet, and a downstream pipe extending from the outlet;
- b) advancing a first composition in a flow path from the first inlet towards the downstream pipe;
- c) introducing a second composition into the first composition via the second inlet, wherein the mixed composition is created;
- and
- d) partially obstructing the flow of the mixed composition in a region of the downstream pipe that is proximate the outlet.
A method of making a mixed composition, the method comprising the steps of:
- a) providing a mixer comprising a first inlet, a second inlet, an outlet, and a downstream pipe extending from the outlet;
- b) advancing a fluid composition in a flow path from the first inlet towards the downstream pipe;
- c) introducing a plurality of particles into the fluid composition via the second inlet, wherein the mixed fluid composition is created;
- and
- d) creating an eddy or vortex in a region of the downstream pipe that is proximate the outlet to help manage accumulation of particles in that region.
A method of making a mixed composition, the method comprising the steps of:
- a) providing a mixer comprising a first inlet, a second inlet, an outlet, and a downstream pipe extending from the outlet;
- b) advancing a fluid composition in a flow path from the first inlet towards the downstream pipe;
- c) introducing a plurality of particles into the fluid composition via the second inlet, wherein the mixed fluid composition is created;
- and
- d) diverting flow of at least some of the mixed fluid composition in a region of the downstream pipe that is proximate the outlet to help manage accumulation of particles in that region.
A mixing system comprising:
- a) a lamella pump, comprising
- i) a first inlet for receiving a first composition,
- ii) a second inlet for receiving a second composition,
- iii) an outlet for communicating a mixed composition comprising the first and second compositions, and
- iv) spaced apart blades rotatable in a direction from a first side of the outlet to a second side of the outlet;
- b) a downstream pipe disposed at the outlet;
- and
- c) an obstruction disposed on an inner wall portion of the downstream pipe proximate the second side of the outlet, wherein the obstruction partially blocks flow of the mixed composition through the downstream pipe.
