Cleaning of waffle irons
Abstract
Food manufacturing and processing company cleaned waffle irons residues in a baking line automatically by a solid-state laser. Before substitution parts are manually cleaned with sodium carbonate and brushes.
Substituted substances
Sodium carbonate
CAS No. 497-19-8 EC No. 207-838-8 Index No. 011-005-00-2
Chemical group

Other type of alternative
Laser cleaning (solid-state laser)
Hazard Assessment
Substance to be substituted: The substituted product sodium carbonate has no harmonised classification according to Annex VI of Regulation (EC) No 1272/2008 (CLP Regulation). Alternative substance: Laser cleaning is used as non-chemical alternative.
Description of Substitution
The company cleaned manual waffle irons in a baking line made of steel using sodium carbonate or steel brushes. Problem related to the use of this system was the breakage of the waffle irons. After that oil from the camps had to be removed and the baking line shut down. Also tiny pieces of wire were found in the waffles. Now the manufacture uses laser cleaning as an alternative.The new system has been integrated into the baking line. The laser cleaner CL 120 Q is ideal for cleaning smooth surfaces, hollow spaces and complicated geometries. A cleaning agent is here not needed, from this side there is no waste produced. The dirt is evaporated by high light energy, is caught to a lesser extent in the filters and goes mainly into the air.
Case/substitution evaluation
In this case story manual cleaning with sodium carbonate was replaced with non-chemical process laser cleaning. The new solution is safer for the described application.
