Methods and apparatus for electrostatic dispensing fluid onto food products are disclosed. An electrostatic dispense system includes a material supply, a voltage block, and a power supply to electrostatically charge a coating material. The electrostatic dispense system further includes a dispense assembly, a conveyor through or by which a food product is configured to be conveyed, and a support that supports at least one liquid outlet of the dispense assembly. The dispense assembly dispenses the electrostatically charged coating material from the at least one liquid outlet onto the food product. The voltage block provides electrical isolation, and includes a pump that pumps the electrostatically charged coating material to the dispense assembly.

Electrostatic dispensing of an anti-microbial coating material

A powder spray gun includes a powder flow path inlet and a powder flow path outlet, the powder flow path inlet being connectable in a first configuration to a dilute phase powder pump and in a second configuration to a dense phase powder pump, wherein the powder spray gun comprises a spray nozzle that is the same for the first and second configurations. The powder flow path is provided by a powder tube that extends through the gun, with the powder tube having a first diameter at an inlet portion of the spray gun and a second diameter at an outlet portion of the spray gun, with the second diameter being greater than the first diameter. The powder flow path may also include a conical transition portion, and a member for adding air to the powder flow.

Powder gun configurable for supply from venturi or dense phase pump

A dense phase pump has two housings that are attached together using a single releasable fastener. The fastener can be released to allow the two housings to be separated thereby providing access to replaceable components. The replaceable components may include one or more pinch valves or one or more barrier elements. A pinch valve for a dense phase pump has a shape or profile for aligning the pinch valve when the pinch valve is installed in a pinch valve body. The pinch valve optionally has two end flanges, with each end flange having a shaped periphery. The two end flanges may have the same size and shape so that the pinch valve can be installed in either of two orientations that are inverse. A dense phase pump has a pump chamber that can be purged by purge gas that enters the pump off-axis from a purge path axis.

Dense phase pump with easily replaceable components

A light assembly coupled to a spray gun for spraying electrostatically charged coating material is disclosed. The spray gun includes a gun body comprising a barrel, a nozzle assembly extending from the barrel in a longitudinal direction, a voltage multiplier, and an actuator assembly configured to transition the voltage multiplier between an activated state and a deactivated state. The light assembly includes a light and circuitry electrically connected to the light. The circuitry is configured to supply electrical energy inductively obtained by the circuitry to the light when the voltage multiplier is in the activated state. The light assembly can also include a housing, a lens cover releasably attached to the housing, and a control member for changing a characteristic of the light.

Retrofit light assembly and powder spray gun with integrated or retrofit light

A diagnostic apparatus for a powder coating material pump. The diagnostic apparatus includes a detector that uses pressure or flow to detect a fault in the pump, the diagnostic apparatus being external the pump, internal the pump or a combination of external and internal the pump. Another diagnostic device is provided for a powder coating material pump, and includes a light source in close proximity to the pump, the light source having an on condition and an off condition wherein one or both of the on condition and off condition provides information about the pump performance. An exemplary pump is a dense phase powder coating material pump.

Dense phase pump diagnostics

A feed center for powder coating material includes a hopper, an extraction duct, and a control valve. The hopper is in fluid communication with a fluidizing pressure source. The extraction duct is in fluid communication with at least one suction source. The control valve connects the extraction duct with an extraction port of the hopper. The control valve is operable between a first position for applying suction from the at least one suction source to the hopper, and a second position providing an exterior opening in at least one of the control valve and the first extraction duct for exhausting pressurized fluid from the hopper and/or collecting at least some of the air and powder that is exhausted from the powder.

A color changer has a common feed passage that is connected to two or more inlet passages. The common feed passage can be reverse purged in a direction that is opposite a direction of powder flow through the common feed passage. A valve element seals a supply port that connects the inlet passage to the common feed passage to eliminate dead space and form a near bore line seal. The valve element is an elastic material that expands in response to applied compressed air inside the valve element.

Powder gun configurable for supply from Venturi or dense phase pump

A selectively configurable spray gun may include a gun body comprising a selectable forward section and a rearward section. The rearward section may be connected with either of two or more selectable forward sections so as to selectively configure the spray gun to operate either with a dense phase powder supply configuration or a with dilute phase powder supply configuration. The rearward section may include a selectable powder flow path that is connectable at an inlet end to a source of dense phase powder and at an outlet end to a selectable spray nozzle in the selectable forward section that may optionally include a diffuser. An adapter may be used to connect the rearward section with a selectable spray nozzle or air cap. A manual spray gun embodiment is also presented. A selectively configurable spray gun for use with a dense phase powder supply may include a smaller diameter powder tube that extends through a larger diameter powder tube.
