Cooling line for chocolate molds

Task: Cooling chocolate in the cooling tunnel

Chocolate molds are filled lengthwise with liquid chocolate in a dosing station

The chocolate molds must then be cooled for a defined period in a 25-meter-long cooling tunnel. The temperature in the tunnel is at least 6°C.

In the cooling tunnel, the molds must be transported in the transverse direction, with four molds forming a row

There must be no gaps between the molds to achieve optimal filling of the tunnel and to maintain the necessary process parameters

When fully loaded, the belt in the cooling tunnel is loaded with approx. 1,200 kg by the molds

In addition, the conveyor belt structure must support the cooling tunnel, which has a total weight of 1,500 kg

The molds must remain in the cooling tunnel for approximately 45 minutes. The cold air must reach all sides of the mold as effectively as possible.

The molds must be fed behind the cooling tunnel to a knock-out station, which removes the chocolate from the mold

Solution: Conveyor belt combination with wire belt conveyor

Belt conveyors for mold transport in the longitudinal direction next to the cooling tunnel

Two 90° belt curves for correct positioning at the cooling tunnel

Two belt conveyors with durable PU treads across in front of and behind the cooling tunnel

Pneumatic cross slide at the inlet of the cooling tunnel

25m long and 1,800mm wide stainless steel wire belt conveyor in special design with optimal air permeability for the cooling tunnel

Cooling belt with extremely high-torque worm gear motor with a drive torque of over 500Nm at only 180W drive power
