Cooling system

Lab 5 Roll Refiner Internals
  • Water automatic heat sensitive
  • Solenoid valves in the cooling water cycle to allow the automatic on and off.
  • In case of pressure drop or no water, the rolls are released from pressure and the system stops automatically.
  • The cooling water system controlled digitally by solenoid valve system.
  • Digital thermo controllers for the rolls controls the water very accurate.
  • Cooling water flows over the water lance in to the roll.
  • Water lance is equipped with thermometer and pressure gauge.
  • Thermo sensor PT100

Driving section

Lab 5 Roll Refiner Helical Gear
  • The helical gear wheels are in the left side of the frame.
  • It is driven with high performance V belts directly on the fifth roll, whereby the V belt pulley is installed in the machine.
  • The roll cooling is located on a block in the right hand side of the frame.
  • Gears are force lubricated with oil pump.

Electric control section

The control unit is in an external control cabinet.

Technical Details

Capacity

Refining capacity of LABORATORY 5 ROLL REFINER depends on the following factors:

  • Thickness of powdered sugar and cacao
  • Ingredients of the cacao liquor (fat content)
  • Thickness of the desired refined product
  • Temperatures of the rollers
  • Previous processing (mixing etc.) of the product before fed into

Product Thickness

5 Roll Refiner Production Thickness

A micrometer (µm) gauge is used to measure the thickness of the refined product. The desired thickness can be set between 12 and 40 µm. usually, the desired thickness is set to 18µ ± 4µ

On this diagram the input product thickness value has been accepted as 100 micron.
