Self cleaning Filtersystem in the production of chocolate

Use of a self-cleaning filter system by Contec© in the production of chocolate

In the field of ​​new development again, a successful example of application in the production of chocolate can be documented.

The filtration challenge:
The chocolate manufacturer Ludwig Weinrich GmbH & Co. KG, Germany wanted to replace the previously used sieve filters (last step before molding) through a self-cleaning filter system as police filter before filling the chocolate.

Medium: Chocolate
Viscosity: 1.5 PaS - 7.5 PaS
Throughput: about 1.5 t/h
Pressure max.: 6 bar, max. temperature: 40 °C
Fineness: 1.5 - 2 mm in order to prevent separation of the chocolate

The solution:
After a very successful trial with an wedge wire filter type AS110K standard of Contec this was modified for special use as follows:

  • The filter is easy to open with a hinged lid.
  • The filter element with the scraper basket can be removed completely to the top without tools.
  • By means of a heating jacket, the filter can be integrated into the existing tracing.
  • An integrated magnetic separator after the filter system provides ultimate security.
  • The discharge is carried out in 3” in order to ensure an easy emptying of the filter.

The company Weinrich GmbH & Co. KG has installed differential pressure monitoring line and found out that the pressure loss is only 0.1 to 0.2 bar.
