Enrober
An enrober is a machine used in the confectionery industry to coat a food item with a coating medium, typically chocolate. Foods that are coated by enrobers include nuts, ice cream, toffee, biscuits and cookies. Enrobing is essentially a mechanized alternative to hand-dipping. Enrobing with chocolate extends a confection's shelf life.
