Abstract

An apparatus and method for coating products is disclosed herein. An exemplary apparatus comprises a vibration generating portion and a product coating portion. The product coating portion can include a coating application portion, a sifting portion, and an aligning portion. The exemplary apparatus can include a coating recycle portion as well. The vibration generation portion further comprises a motor vibration assembly secured to a frame wherein the frame is in communication with the product coating portion, such as a pan assembly, by springs that move the pan assembly with a vibratory motion. The product coating portion includes a series of angled steps that guide the coating and vibrating product upwards and forward, while simultaneously allowing the product to be agitated against the coating resting on the step surface. Additionally, the product coating portion can include a moveable wire belt conveyor assembly.

Claims

1. An apparatus for applying coating to products comprising:

a vibration generating portion, for providing a vibratory motion, and

a product coating portion, for receiving the vibratory motion and applying a coating to a product;

wherein, the vibration generating portion comprises a vibratory frame assembly that includes a motor vibration assembly, and the product coating portion includes a pan assembly, wherein the vibratory frame assembly is in communication with the pan assembly by spring assemblies that move the pan assembly with a vibratory motion; and

wherein the pan assembly includes at least one of a coating application portion, a sifting portion, and an aligning portion; and

wherein when included, the coating application portion further comprises one or more steps to guide the coating and the product upwards and forwardly, while simultaneously allowing the product to be vibrated against the coating resting on the one or more steps; and

wherein when included, the sifting portion succeeds the coating application portion, if included, and the product continues to vibrate across the one or more steps of which slots are formed therein, and where excess coating flows through the slots.

2. The apparatus of claim 1 further including, a recycle conveyor for collecting the coating that does not adhere to the product and returning the coating to the product coating portion for application to other products.

3. The apparatus of claim 1 wherein the coating that passes through the slots is collected and guided into at least one of a hopper and a recycle conveyor that conveys the coating back to the coating application portion.

4. The apparatus of claim 3 wherein the aligning portion further comprises a corrugated surface situated at an incline having tray channels formed by the corrugations that are substantially parallel with the length of the pan assembly, the tray channels being situated to bias the product such that it can be elongated and aligned from the vibrations.

5. The apparatus of claim 4 wherein an additional sifting portion can be provided that comprises another aligning portion having holes situated there-through to allow agglomerations of coating and fragmented product to pass through, thereby removing them from the process.

6. The apparatus of claim 1 further including a base recycle conveyor and a waterfall recycle conveyor for recycling coating, wherein each conveyor includes a conveyor channel having a lower length, an upper length, an ascending portion and a descending portion, and a looped drag-chain belt having one or more flights situated at least partially in the channel for transporting coating from the lower length to the upper length via the ascending portion, with the lower lengths of at least one channel receiving coating from one end of the apparatus, and the upper lengths releasing coating at another end of the apparatus adjacent to the product coating portion.

7. An apparatus for applying coating to products comprising:

a wire conveyor belt assembly capable of receiving coating and food products and applying the coating to the products,

a pan assembly capable of receiving coating and products and applying the coating to the products, and

a vibration generating portion for providing a vibratory motion to the pan assembly;

wherein the apparatus further includes at least one of a base recycle conveyor and a waterfall recycle conveyor for collecting coating that does not adhere to the product and supplying for application to at least one of a bottom and top portion of a product; and

wherein each conveyor includes a conveyor channel having a lower length, an upper length, an ascending portion and a descending portion, and a looped drag-chain belt having one or more flights situated at least partially in the channel for transporting coating from the lower length to the upper length via the ascending portion, with the lower length of at least one channel receiving coating from a discharge end of the pan assembly, and the upper length of at least one channel releasing coating adjacent an inlet end of the pan assembly.

8. The apparatus of claim 7, wherein the vibration generating portion comprises a vibratory frame assembly that includes a motor vibration assembly in communication with the pan assembly by springs that are capable of moving the pan assembly in a vibratory motion, and a support frame isolated from the vibratory motion.

9. The apparatus of claim 8, wherein the support frame includes a swing frame portion that supports the wire conveyor belt assembly, such that the wire conveyor belt assembly is movable from a non-production position to a production position, wherein the production position allows product to be transported on the wire conveyor belt assembly.

10. The apparatus of claim 9 wherein the pan assembly includes at least one of a coating application portion, a sifting portion, and an aligning portion.

11. The apparatus of claim 10 wherein the coating application portion further comprises one or more steps that utilize the vibratory motion to guide the coating and the product up and over each step, while simultaneously allowing the product to be vibrated against the coating on the step surface.

12. The apparatus of claim 11 wherein the sifting portion succeeds the coating application portion and where the product continues to vibrate across one or more steps of which slots are formed therein, and where excess coating flows through the slots.

13. The apparatus of claim 12 wherein the coating that passes through the slots is collected and guided into at least one of a hopper and the recycle conveyor.

14. The apparatus of claim 13 wherein the aligning portion further comprises a corrugated surface situated at an incline having tray channels formed by the corrugations that are substantially parallel with the length of the pan assembly, the tray channels being situated to bias the product such that it can be elongated and aligned from the vibrations.

15. The apparatus of claim 14 wherein an additional sifting portion can be provided that comprises another aligning portion having holes situated there-through to allow agglomerations of coating and fragmented product to pass through, thereby allowing them to be removed from the steps.
