Abstract
A product on demand nozzle assembly includes a chamber at least partially defined by an external wall and an array of vertically spaced nozzles. Each nozzle has an air inlet, an air and entrained product outlet extending from the external wall, and an entrainment zone between the air inlet and the air and entrained product outlet to receive a product therein to be distributed.
Claims23
A product on demand nozzle assembly comprising:
- a chamber at least partially defined by an external wall;
- and
- an array of vertically spaced nozzles, each nozzle having an air inlet, an air and entrained product outlet extending from the external wall, and an entrainment zone within the chamber and between the air inlet and the air and entrained product outlet to receive a product therein to be distributed,
- wherein the array of vertically spaced nozzles open to a common product inlet, and
- wherein the product in the chamber is capable of moving from an entrainment zone of a first nozzle of the array of vertically spaced nozzles to an entrainment zone of a second nozzle of the array of vertically spaced nozzles.

A product on demand nozzle assembly comprising:
- a chamber at least partially defined by an external wall;
- and
- an array of vertically spaced nozzles, each nozzle having an air inlet, an air and entrained product outlet extending from the external wall, and an entrainment zone within the chamber and between the air inlet and the air and entrained product outlet to receive a product therein to be distributed,
- wherein a first nozzle of the array of vertically spaced nozzles is positioned vertically above a second nozzle of the array of vertically spaced nozzles such that the first nozzle is aligned vertically with the second nozzle,
- wherein each nozzle includes a bridge member connecting the air inlet to the air and entrained product outlet, and
- wherein each bridge member extends above the respective entrainment zone to reduce a weight force of an additional amount of product located above the respective entrainment zone on the product within the respective entrainment zone.
