Positive displacement mixer

A method for mixing a product, the method including the following steps:

• a. providing a positive displacement mixer comprising:
• i. two or more primary positive displacement elements each comprising a primary compartment comprising a primary volume;
• ii. two or more minor positive displacement elements each comprising a minor compartment comprising a minor volume;
• wherein the two or more primary compartments and the two or more minor compartments are fluidly connected;
• b. loading the two or more primary compartments with at least two materials in each primary compartment or loading the two or more minor compartments with at least two materials in each compartment;
• c. closing the primary and minor positive displacement elements to the atmosphere;
• d. mixing the one or more materials using laminar flow by a mixing method selected from the group consisting of Method A, Method B, Method C, Method D, and Method E, and combinations thereof;
• wherein Method A comprises:
• i. transferring the materials from the one or more primary compartments to each minor compartment one at a time;
• ii. then, simultaneously transferring the material from the minor compartments to the one or more primary compartments to complete one cycle;
• iii. repeating steps i to ii until the desired level of mixedness is obtained forming a product;
• wherein Method B comprises:
• i. simultaneously transferring the materials from the one or more primary compartments to the two or more minor compartments;
• ii. then, transferring all the material from each minor compartment to the primary compartment one at a time to complete one cycle;
• iii. repeating steps i to ii until the desired level of mixedness is obtained forming a product;
• wherein Method C comprises:
• i. simultaneously transferring the materials from the one or more primary compartments to the two or more minor compartments;
• ii. then, simultaneously transferring the material from the minor compartments to the one or more primary compartments to complete one cycle;
• iii. repeating steps i to ii until the desired level of mixedness is obtained forming a product;
• wherein Method D comprises:
• i. transferring the materials from the two or more minor compartments to each primary compartment one at a time;
• ii. then, simultaneously transferring the material from the two or more primary compartments to the two or more minor compartments to complete one cycle;
• iii. repeating steps i to ii until the desired level of mixedness is obtained forming a product;
• wherein Method E comprises:
• i. simultaneously transferring the materials from the two or more minor compartments to the two or more primary compartments;
• ii. then, transferring all the material from each primary compartment to the minor compartments one at a time to complete one cycle;
• iii. repeating steps i to ii until the desired level of mixedness is obtained forming a product;
• e. dispensing the product into a final container.

A positive displacement mixer for mixing a product that mixes at least two materials into a homogenous product, the device comprising:

• at least three positive displacement elements comprising:
• i. a primary positive displacement element comprising a length, primary compartment, and a moving element;
• and
• ii. two or more minor positive displacement elements each comprising a length, a minor compartment, and a moving element;
• wherein the primary compartment and the minor compartments are fluidly connected;
• wherein during mixing the primary compartment and minor compartments are closed to the atmosphere;
• and
• wherein the primary compartment and the minor compartments comprise variable volumes as determined by moving the moving element across the length of the positive displacement elements.
