Cooling Track for Chocolate Moulds

Task: Cooling down chocolate within a cooling tunnel

Chocolate moulds are transported in the lengthwise direction into a dosing station where they are filled with liquid chocolate
Afterwards the moulds have to be cooled within a 25m long cooling section. The minimum temperature within the tunnel is 6°C.
Inside the cooling section the moulds have to be transported in transverse direction with four moulds in one row
There must not be any gap between the moulds in order to allow an optimized filling level and to ensure the necessary process parameters
The maximum load on the conveyor is 1,200kg
Additionally the conveyor has to carry the tunnel construction with a total weight of 1,500kg
The moulds have to stay 45 minutes in the cooling section. It is important that the cold air reaches the moulds
Behind the cooling section the moulds have to be transferred into a demoulding station, where the chocolate is pulled out of the mould
Afterwards the empty moulds need to be transferred to the dosing station where the process starts again

Solution: Use of conveyor combination with steel mesh conveyors

Belt conveyors to transport the moulds lengthwise parallel to the cooling section
Two 90° belt curves to keep the orientation of the moulds when turning
Two belt conveyors with strong PU belt transversely in front of and behind the cooling section
Pneumatic pusher at the inlet of the cooling section
25m long and 1,800mm wide stainless steel mesh conveyors in special design with optimized air permeability for the cooling section
Cooling conveyor with extra strong motor (more than 500Nm torque) and only 180W drive power
