DCM Pneumatic Pressure System




Constant and uniform stone pressure is one of the key variables in successful and efficient chocolate refining. Controlling this variable helps ensure that every run is uniform in particle size, flavor and texture. Repeatability from batch to batch is more easily achieved using a DCM Pneumatic Pressure System. This simple accessory can save makers up to 25% refining time. It can also help when developing Standard Operating Procedures to minimize human error and product variability. The device helps achieve maximum efficiency of the refining capacity which keeps production costs low and ensures higher yield utilization of the machine. 

In the traditional mechanical spring tension method, the decreasing micron size of the product during refining results in decreasing stone pressure. Consequently, refining is less productive and batch refining times are longer. The Pneumatic Pressure System applies consistent and even pressure throughout the entire batch without the need for continuous babysitting of the machine. The Pneumatic Pressure System also extends the life of the machine by preventing the over-tensioning of the roller stones which results in premature wearing down of the components and the machine.

Makers can also conch with this accessory simply by removing the pressure on the stones.

The DCM Pneumatic Pressure System runs on a standard air compressor or your shop’s compressed air supply. The DCM Pneumatic Pressure System attaches discreetly onto the main frame of the machine and the horizontal top bar and will not interfere with loading processes.

Available on DCM Melanger 20, 35, 70, 100, 150 or 200 at the time of purchase. 


Technical Specifications and Dimensions:

  • The nominal operating pressure is between 20 and 30 psi. 
  • A standard air compressor with a small storage tank that can generate up to 100 psi in pressure. 
  • The air connection to the machine is a ¼” female NPTF sleeve-lock socket connector attaching to a male connector located on the machine.


Please note that all accessories, including the Pneumatic Pressure System, are built into the machine during production, and therefore have to be requested at the time of machine order.

NOTE: Due to continuous product improvement, design changes are made from time to time. Some changes and modifications may not be covered in this page.
**Please note that air compressor is not included. Most hardware stores sell very economical models, and the newer, quieter air compressors actually make less noise than many refiners.
