CLEANING OF BAKING PLATES

November 1st, 2011

LaserAge offers a unique cleaning solution for baking plates and other “hot” surfaces used in food processing. Metallic baking trays, molds, and conveyors can be cleaned free of oil, grease and deposits quickly and residue-free with our laser technology. Flat and textured baking molds of steel, cast iron or chrome plated metal are well-suited for laser cleaning.

We offer laser cleaning solutions designed to operate consistently inside hot ovens (and hot molding plates) during normal production at temperatures higher than 180 °C.

Moving baking plates and other challenging surfaces can be laser treated on the fly and maintained in a permanently cleaned condition, with increased equipment up-time and reduced costs..

BENEFITS

Clean on-line and off-line.   Removes baked-on deposits without harm to baking surfaces.  Uses no media, no dust, no chemicals, no clean-up & no residue.    Eliminates use of abrasive wire brush cleaning & risk of stray metal wires.   Environmentally friendly – no seconday waste.   Low operating cost.  Minimal maintenace.

Typical Applications;

  • Cleaning of sugar cone molds
  • Cleaning of waffle molds
  • Cleaning of product handling components & conveying systems
  • Other challenging baking & food processing applications

Limitation - residues of meat, chocolate as well as powder and inhomogeneous (thick) materials

Laser Cleaning update

Cleaning of optical moulds.  the moulds were Cr plated, stainless steel polished moulds.  The contaminant was biosoy, a production resin which is used in the production of the contact lenes.  The low power CL120 system was used.. It was manual cleaning with Stylus optics.  The technical feasibility was good with flexibility to automate at a later stage.

Laser Cleaning

September 7th, 2010

When laser light strikes a solid surface with sufficient energy, a thin layer (of contaminant or paint) can be removed.  The idea is to remove the contaminant without damaging or structuring the underlying surface.   The technical term for this is laser ablation but most people refer to it as laser cleaning.

At low laser power (flux), the material is heated by the absorbed laser energy and evaporates or sublimates.  At higher laser flux, the material is typically converted to a plasma and is ablated.  Usually, laser ablation refers to removing material with a pulsed laser, but it is possible to ablate material with a continuous wave (cw) laser beam if the laser intensity is high enough.

The depth over which the laser energy is absorbed, and thus the amount of material removed by a single laser pulse, depends on the material’s optical properties and the laser wavelength.  Anywhere from less than several microns to several hundred microns can be removed.  Laser pulses also vary over a wide range of durations (milliseconds to femtoseconds) and fluxes, and both can be precisely controlled.

This makes laser ablation a very valuable cleaning tool with many industrial applications from the medical, aerospace, injection mould tooling, semiconductor and auto industries, as well as conservation.
