Chocolate Coating Machine (With Cooling Tunnel)

This chocolate coating machine is a kind of versatile food processing equipment designed for producing not only chocolate biscuits but also other biscuits with different taste by coating other thick liquids that have almost the same viscosity and mobility as chocolate liquid. The chocolate coating equipment is provided with a cooling tunnel which is specially designed for cooling the coated chocolate liquid.

Work Flow
The baked biscuits are conveyed from cooling conveyor to stacker where they will be in incomplete standing condition. Then, they will be transported to the vibrating feeder and sandwiching machine. After sandwiched, they enter cooling tunnel via different lanes. After cooled, they will be automatically separated into several flows and respectively coated with chocolate. When the coating is cooled, the end biscuits will be conveyed to the packing machine.
