There is another chocolate punching line suitbale for mass producing chocolate coins.
Chocolate will be fed on a conveyor with a blade sits at its entrance position, chocolate spread evenly on the conveyor to create a long sheet of chocolate layer, the blade level could be adjust to get a specific thickness of this chocolate layer.
As the conveyor moves through a cooling tunnel, chocolate will be cooled from liquid to soft solid status, a unique spring-loaded cutter will punch out round or rectangular shaped chocolate coin blanks, operators could collect these chocolate blanks on top of the cutter tubes.
Leftover chocolate will be transferred back to chocolate melting machine so not a crumb of chocolate will be wasted.
