The paddle revolves around the central cone of the tank, keeping the curd moving and ensuring that every block former is served with an even amount of product.
This unique seal was originally invented for use in Tetra Pak® cheese vats, but is now also used in this tank. Thanks to a Q-shaped cross section, it creates a watertight connection between the cone and the shaft inside the tank. This eliminates the risk of leaked product interfering with the workings of the drive – thus enabling it to be placed directly beneath the tank, which in turn enables a smaller machine footprint.
A sensor in the tank detects the level of curds, and only activates the filling sequence when there is sufficient product to start filling the block formers. This not only saves energy, but also prevents curd from cooling down.
