What is the most save way to filter big particles out of the cocoa powder?We are considering metal woven wire mesh and blue polyester wire cloth to use as a big round filter. However, we are not sure that we can detect and filter out all of the metal particles out of the cocoa powder once the metal wire mesh gets damaged. On the other side, we are considering to make use of a blue polyester wire cloth filter, blue is easy recognizable within foods due to the deviating color of the polyester.
What would you recommend us?
