Abstract

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.
