The icer/glazer applies string icing and a waterfall curtain icing onto a wide variety of both panned and unpanned products. The icer uses a double-walled heated and agitated tank with variable frequency pump and filter assembly. An oscillating icing head is used for string icing and an adjustable waterfall trough is used for curtain icing. The conveyor hinges up away from the icer for easy cleaning and loading of icing. The conveyor uses a two-part pass through wire mesh conveyor with catch pans, and an optional removable center belt section is used for icing small unpanned products.
