Frisse-DUC – double overthrow conche for top quality.

- Efficient and flexible
- High product quality
- Minimized running times

Frisse-DUC.

The Frisse-DUC is an efficient double overthrow conche equipped with three shafts. Thanks to their specific geometry, the agitators of this classic conche are capable of either shearing or lubricating the chocolate mass, depending on the direction of rotation. Thanks to its high capacity, this machine ensures the best possible conching within the shortest time possible – from refiner product to flowing mass. The Buhler Frisse-DUC can operate in the automatic or manual mode and can be integrated in the process automation system of chocolate factories. Efficient and flexible thanks to sophisticated technology. 
  • The specific configuration of the three rotors produces a double overthrow of the chocolate. The blades move synchronously and in opposite directions so that shear zones are created in addition to those existing between the rotors and the vessel wall – thus producing optimal conditions for an efficient conching process. 
  • The sophisticated and individually configurable interaction between process control, aeration, temperature control, energy input, and direction of rotation of the conching shafts enables a wide range of chocolate conching variants. This allows diverse masses to be processed for making a wide variety of end products according to the specific requirements.

High product quality through optimal aeration.
The double overthrow action draws in air on one side of the conche, forces it through the mass, and ejects it again on the other side. This ensures consistent moisture extraction from the product mass – improving the end product flavor as well as the texture.

Frequency-converter-controlled drive for minimized running times.
The DUC conche is equipped with a frequency-converter-controlled drive. It allows an extremely high throughput capacity and reduces the conching times.
