A system (100, 200, 300) for producing chocolate-based articles in solidifying form, the system comprising: a transportation system comprising at least a first conveyor belt looped around at least first and second axes (102, 113); a dispensing unit arranged for dispensing chocolate mass in liquid form along an outer surface of the top load carrying side of the at least first conveyor belt at an entry point of the transportation system; at least one cooling chamber arranged for cooling the chocolate mass under predetermined conditions before the chocolate mass is collected at an exit point of the transportation system; wherein the at least one conveyor belt is arranged for transporting the chocolate mass through the at least one cooling chamber at a predetermined speed along a first and a second cooling path, the first and second cooling paths being positioned opposite one another and are connected via at least the first surface such that the direction in which the chocolate mass is transported in the second cooling path is opposite to that of the first cooling path, characterised in that the at least first conveyor belt comprising a substantially flat top load carrying side and a substantially flat bottom load carrying side interconnected with one another via at least first and second curved surfaces (110, 114) formed respectively at the location of the at least first and second axes (102, 113); in that the first and second cooling paths are located respectively on the top load carrying side and bottom load carrying side of the conveyor belt; and in that the system (100, 200) further comprises a release mechanism (107, 207) positioned along the second cooling path, the release mechanism (107, 207) being arranged for releasing the chocolate mass from an outer surface of the bottom load carrying side of the at least first conveyor belt. a transportation system comprising at least a first conveyor belt looped around at least first and second axes (102, 113); a dispensing unit arranged for dispensing chocolate mass in liquid form along an outer surface of the top load carrying side of the at least first conveyor belt at an entry point of the transportation system; at least one cooling chamber arranged for cooling the chocolate mass under predetermined conditions before the chocolate mass is collected at an exit point of the transportation system; wherein the at least one conveyor belt is arranged for transporting the chocolate mass through the at least one cooling chamber at a predetermined speed along a first and a second cooling path, the first and second cooling paths being positioned opposite one another and are connected via at least the first surface such that the direction in which the chocolate mass is transported in the second cooling path is opposite to that of the first cooling path, characterised in that the at least first conveyor belt comprising a substantially flat top load carrying side and a substantially flat bottom load carrying side interconnected with one another via at least first and second curved surfaces (110, 114) formed respectively at the location of the at least first and second axes (102, 113); in that the first and second cooling paths are located respectively on the top load carrying side and bottom load carrying side of the conveyor belt; and in that the system (100, 200) further comprises a release mechanism (107, 207) positioned along the second cooling path, the release mechanism (107, 207) being arranged for releasing the chocolate mass from an outer surface of the bottom load carrying side of the at least first conveyor belt.
