Understanding Electrostatic Coating Equipment Technology
Based on the principle of positives and negatives attract
A charging electrode is located at the tip of the electrostatic probe. An electrostatic field is created between the charging electrode and the grounded product. The atomized powder/oil is ionized as it moves past the electrode, where the particles become negatively charged.
The product to be coated (chips, snacks, etc.) is grounded from contact within the rotating drum, or wire belt. When the coating material is released, it is attracted to the grounded product. Due to the electrostatic attraction, coating material that would normally be lost ends up on the back and sides of the target product to produce a “wrap-around” effect.
