Abstract

An inductor assembly is configured to be attached in flow communication to receive a flow of product from a storage hopper of a product conveyance system. The product conveyance system includes a forced fluid source mounted thereon and operable to provide a forced fluid stream to the inductor assembly. The inductor housing includes an inlet configured to direct a first portion of the forced fluid stream in a path to engage the flow of product so as to generate the combined stream of forced fluid and product. The inductor assembly further includes multiple inductor segments, wherein each inductor segments defines at least one conduit having an inlet and an outlet. One or more of the inlets may be configured to restrict air and product flow therethrough.

Claims

1. An inductor assembly of a product conveyance system having a storage hopper for a product and a forced fluid stream, the inductor assembly comprising:

an inductor housing configured to receive a flow of product from the storage hopper, the housing including an air inlet configured to direct the forced fluid stream in a direction toward the flow of product so as to generate a combined stream of forced fluid and product, wherein the air inlet includes a first portion and a second portion;

a plurality of inductor segments, each inductor segment defining a first conduit and a second conduit, the first conduit having a first inlet, a first outlet, and a first product/air mixture inlet in fluid communication with the first outlet, and the second conduit having a second inlet, a second outlet, and a second product/air mixture inlet in fluid communication with the second outlet, and wherein the first and the second inlets are configured to receive air from the first portion of the air inlet and the first and the second product/air mixture inlets are configured to pass product suspended in air, wherein the air is received from the second portion of the air inlet; and

wherein the plurality of inductor segments include a first inductor segment and at least a second inductor segment; and

wherein the inlet of one of the first conduit and the second conduit of a selected inductor segment has an inlet size different than the inlet of the other one of the first conduit and the second conduit of the selected inductor segment; and

a restrictor plate mounted to the inductor housing and positioned between the second portion of the air inlet and the air/product mixture inlets of the plurality of inductor segments, and wherein the restrictor plate extends across a width of the inductor housing defining the second portion of the air inlet and wherein the restrictor plate has a height that varies along the width of the inductor housing.

2. The inductor assembly of claim 1 wherein each inlet includes an orifice plate having an opening formed in the plate.

3. The inductor assembly of claim 2 wherein the orifice plate seated in the inlet of the one of the first conduit and the second conduit has an opening that is sized different from that of the opening of the orifice plate seated in the inlet of the other one of the first conduit and the second conduit.

4. The inductor assembly of claim 3 wherein each orifice plate is removably secured to a respective inlet.

5. The inductor assembly of claim 3 wherein the first conduit of an inductor segment has a length greater than a length of the second conduit of the inductor segment.

6. The inductor assembly of claim 5 wherein the first inlet of the first conduit has an orifice plate having a wider opening than the opening of the orifice plate of the second inlet of the second conduit.

7. The inductor assembly of claim 1 wherein the first portion of the air inlet comprises an upper air inlet and the second portion of the air inlet comprises a lower air inlet.

8. The inductor assembly of claim 7 wherein the restrictor plate is mounted to a lower end of the inductor housing.

9. The inductor assembly of claim 8 wherein the restrictor plate is removably mounted to the inductor housing.

10. The inductor assembly of claim 8 wherein the restrictor plate is configured to create a non-uniform air flow distribution across the lower air inlet.
