Material reconditioning and dispensing system

A dispensing system for dispensing a material to a deposition point, the dispensing system comprising:

• a nozzle configured to dispense the material;
• a doser in fluid communication with the nozzle, the doser including a displacement rod and a motor configured to move the displacement rod to control flow of the material to the nozzle;
• a material conditioning assembly upstream of the doser such that the material flows from the material conditioning assembly to the doser, the material conditioning assembly including:
• a first conditioning chamber configured to receive the material therein;
• a second conditioning chamber;
• a first drive member movable within the first conditioning chamber to apply shear stress to the material within the first conditioning chamber;
• a second drive member movable within the second conditioning chamber to apply shear stress to the material within the second conditioning chamber;
• a primary chamber in fluid communication with both the first conditioning chamber and the second conditioning chamber to allow the material to flow between the first conditioning chamber and the second conditioning chamber by way of the primary chamber;
• and
• an actuator configured to simultaneously move both the first drive member and the second drive member in opposite directions to apply shear stress to the material;
• and
• a control module configured to determine viscosity of the material based on speed of the first drive member and power consumed by the actuator to move the first drive member when the first conditioning chamber is full of the material;
• wherein when the viscosity determined by the control module is higher than a predetermined target viscosity, the control module is configured to increase power to the actuator to accelerate the first drive member to apply additional shear stress to the material.

• and
• a stop valve at an outlet of the primary chamber, the stop valve configured to stop flow of the material to the doser when the stop valve is closed.
