Industrial food line mixers-dispersers

Homogenization (mixing and making homogeneous emulsions) and dispersion (creating water or other emulsions) – are the most commonly used processes in the food industry, along with thermal treatment. Most of dairy or high-fat products, sauces, ketchups, concentrates, etc. are obtained by processing components in line mixers-dispersers (colloid mills)

Food industry favors continuous production lines. This is due to a limited shelf life of raw materials, packaging automation and constant consumption of products.

  • Continuous  mixing takes place in colloid mills, food dispersers-homogenizers, fitted into a production line.
  • Maintaining a desired temperature (from +30 to +180°C), ie fitting the equipment with temperature sensors and cooling or heating systems (thermal jackets) is an important condition for operation.
  • Homogenization to particle size from 1 micron is often required.
  • Food mixers-dispersers must meet all sanitary standards.

Structural elements of a food dispersants

  • High-speed electric drive (3000 rpm.);
  • Cavitational colloid mill made from stainless steel;
  • Inlet and outlet pipe systems (with additional pumps as gomogenizators are usually not self-priming);
  • Electronic control unit;
  • Thermal jacket;
  • Sound proofing (if necessary)

Advantages of this colloid mill

Compared to batch units (turbine stirrer), food line dispersers-mixers have a number of advantages:

  • High capacity (up to 20 m3 / h);
  • High efficiency (fine dispersion and homogeneity of obtained emulsions);
  • Adjustment of the gap between rotor and stator (without dismantling the equipment) to vary the size of droplets in a suspension;
  • Cavity (air and liquid bubbles) splitting in the dispersion process results in emulsion that does not separate;
  • No need for additional mixing containers – the process is integrated into the production line;
  • Closed chamber eliminates the ingress of foreign matter or contaminants.
