Enrober

An enrober is a piece of industrial equipment used to coat a product with a liquid substance, typically chocolate but also other coatings like sugar or glaze. It's commonly used in the confectionery industry for covering items such as nuts, candies, and biscuits, but we use it on protein bars.

How it works

  • Product Feeding: The product to be coated (e.g., nuts, candies, protein bars) is fed into the enrober.
  • Coating Application: The product is conveyed through a tank of liquid coating, where it becomes fully covered.
  • Excess Removal: Excess coating is removed through vibration or air blowing.
  • Tempering: In the case of chocolate, the coated product often passes through a tempering section to achieve the correct crystal structure for a desirable snap.
  • Cooling: The coated product is cooled to solidify the coating.
