When mixing powder into a liquid, the following problems are common:
  • Dust
  • Contamination of the working area
  • Dirty powder transporting systems, that are difficult to clean
  • Detrimental to health
  • Exhaust systems and filters have to be installed
  • Loss of powder (during filling, in the filter of exhaust systems, remnants in the bags)
  • Partial wetted crusts at the wall of the vessel and mixing shaft
  • Agglomerates in the product
Powder or granulates are inducted directly into the liquid by a vacuum and they are immediately wetted and dispersed the moment they come in contact with the liquid. For this process no vacuum vessel or additional vacuum pump or powder transportation system is required. The induction vacuum is created by the highly accelerated liquid stream itself. It inducts the powder, fluidises it and brings it - finely distributed - into contact with the liquid. During wetting the powder is simultaneously dispersed, no lumps or agglomerates can build up. TDS-machines (Ystral) handle all processing steps: barrel emptying, powder transportation, dosing, wetting and dispersing up to a complete desagglomeration of the powder.
