Hot Start Conditioner (HSC)

The Hot Start Conditioner is a closed, heated mixing chamber for consistent thermal treatment of meal and powders. Steam and liquids are added through the shaft, with large adjustable paddles ensuring uniform mixing. Electric heating and PT100 sensors control discharge at the set temperature, delivering full conditioning from start up for improved feed safety, higher efficiency, and reliable bacterial reduction.

  • Eliminates need for bypass system
  • Homogeneous and hygienic mixing
  • Robust stainless-steel construction

Technical stability from start-up

The Hot Start Conditioner provides a thermally stable process from the first batch by combining insulated housing, controlled electric heating and precise steam dosing. Bidirectional shaft rotation and adjustable paddles ensure uniform mixing and consistent heat transfer. Accurate temperature control prevents fluctuations at start-up, improves process repeatability and reduces mechanical and thermal stress on downstream equipment.
