Plastic surfaces of trays become electrostatically charged and attract particles and dust from the environment when passing through several production steps. The Traymaster by Kist + Escherich presents an effective and extremely efficient cleaning machine to remove unwanted electrostatic charges and carried particle accumulations along the process chain in one step. The machine gently cleans the top and bottom of trays to prevent contamination during stacking operations. The surface cleaning system can be individually integrated into existing production lines, used as a stand-alone solution or as a sluice between grey and clean room.
