## Abstract

A self-contained system is provided for cleaning a food flow path in a food processor. The system can be operably engaged without requiring disassembly and reassembly of the food processor or can be operably engaged after a partial disassembly of the food processor. The system includes a control assembly for directing passage of a solution through the food processor without requiring constant operator oversight. The system can employ available positive pressure water supply, such as public utility water pressure to selectively and automatically push solutions, including rinses, backwards or forwards through a food flow path in the food processor, though typically countercurrent to the normal processing food flow. A manifold assembly includes an intake manifold and a distribution manifold, with an induction port and/or access port in the distribution manifold for introducing additives or agents into a controlled motive stream passing through the manifold assembly.

## Claims

### Claim 1

A method comprising;
(a) engaging a manifold assembly with a food processor having a food flow path with a dispensing valve in the food flow path controlling flow of the food product in the forward direction passing through a dispensing port, the dispensing valve moveable between an open position and a closed position, and the manifold assembly including distribution manifold having a wash barrel sized to be received within the food processor and move the dispensing valve to the open position, the food flow path having a forward flow direction for processing a food product from an upstream end to the dispensing port;
(b) passing a pressurized cleaning solution from the engaged manifold assembly through the dispensing port to pass the cleaning solution along a portion of the food flow path in a reverse flow direction from the dispensing port toward the upstream end; and
(c) passing the cleaning solution through a bypass line to isolate a portion of the food flow path from the cleaning solution.

### Claim 2 (depends on 1)

The method of claim 1, further comprising manually introducing a cleaning agent into the manifold assembly.

### Claim 3 (depends on 1)

The method of claim 1, further comprising passing the cleaning solution through an aperture in a bushing to expose an upstream side and a downstream side of the bushing to the cleaning solution.

### Claim 4 (depends on 1)

The method of claim 1, further comprising passing the cleaning solution through a plurality of apertures in a beater blade within the food flow path.

### Claim 5 (depends on 1)

The method of claim 1, further comprising automatically cycling the cleaning solution and a rinse in the reverse direction along the food flow path.

### Claim 6 (depends on 1)

The method of claim 1, further comprising locating an aperture in a beater blade in the food flow path for food product having at least an 8% fat content or at least an 8% solid content.

### Claim 7

A method comprising;
(a) engaging a manifold assembly with a food processor having a food flow path with a dispensing valve in the food flow path controlling flow of the food product in the forward direction passing through a dispensing port, the dispensing valve moveable between an open position and a closed position, and the manifold assembly including distribution manifold, the food flow path having a forward flow direction for processing a food product from an upstream end to the dispensing port;
(b) passing a pressurized cleaning solution from the engaged manifold assembly to pass the cleaning solution along a portion of the food flow path in a reverse flow direction; and
(c) passing the cleaning solution through a bypass line to isolate a portion of the food flow path from the cleaning solution.

### Claim 8 (depends on 7)

The method of claim 7, further comprising manually introducing a cleaning agent into the cleaning solution through the manifold assembly.

### Claim 9 (depends on 7)

The method of claim 7, further comprising manually introducing a cleaning agent into the cleaning solution.

### Claim 10 (depends on 7)

The method of claim 7, further comprising passing the cleaning solution through an aperture in a bushing to expose an upstream side and a downstream side of the bushing to the cleaning solution.

### Claim 11 (depends on 7)

The method of claim 7, further comprising passing the cleaning solution through a plurality of apertures in a beater blade within the food flow path.

### Claim 12 (depends on 7)

The method of claim 7, further comprising automatically cycling the cleaning solution and a rinse in the reverse direction along the food flow path.

### Claim 13 (depends on 7)

The method of claim 7, further comprising locating an aperture in a beater blade in the food flow path for food product having at least an 8% fat content or at least an 8% solid content.

### Claim 14 (depends on 7)

The method of claim 7, further comprising fluidly connecting a wand assembly to the manifold assembly.

### Claim 15 (depends on 7)

The method of claim 7, further comprising automatically introducing a cleaning agent into the cleaning solution through the manifold assembly.

### Claim 16 (depends on 7)

The method of claim 7, further comprising automatically introducing a cleaning agent into the cleaning solution.
