Human milk pasteurizer

[Ref : PAS10003]

The PAS10003 pasteurizer processes up to 63 bottles, eliminating all microorganisms that may contaminate the milk while preserving its nutritional and immunological properties.

Complies with SoHO standard 2024/1938/OI.

Several studies have shown that exposing milk to temperatures above 58°C for extended periods significantly degrades its immunological components (see studies by Prof. Czank, Dr. Buffin, Lactarium Paris). For this reason, all our pasteurizers are equipped with highly precise temperature regulation systems to prevent excessive heat exposure. Only a qualification using probes placed inside the bottles can accurately verify the temperatures.

  • Homogenization system
    • Water agitation by a propeller ensuring bath uniformity within ±0.5°C.
    • Bottle agitation guaranteeing milk homogeneity (only performance qualification can verify bath homogenization).
  • Cooling and water treatment
    • Rapid water cooling.
    • Bath water filtration at 0.22 micron to prevent contamination.
    • Connection to a blast freezer possible.
  • Reliability
    • Robust tank and frame fully made of 304L stainless steel.
    • Corian® top surface ensuring optimal hygiene and high chemical and mechanical resistance.
    • French manufacturing and quality.
  • Ease of use – automated control system
    • Intuitive multi-language control via color touchscreen interface.
    • Automatic cycle and cooling regulation.
    • Automatic water level adjustment depending on the load.
    • Self-diagnostics and cycle validation.
    • Pasteurization controlled via an in-load probe placed inside a reference bottle.
    • Detection of in-load probe insertion.
    • Fully customizable cycle parameters with access code: temperature (50 to 70°C), duration (1 to 99 minutes), cooling temperature.
  • Integrated traceability system
    • Traceability connected to a PC or the facility’s IT network.
    • Integration with MO Lactarium.
    • Automatic archiving of graphs, data, and cycle numbering.
    • Real-time cycle monitoring with time/temperature curves.
    • Milk and water temperature graphs.
    • Minimum and maximum temperatures recorded.
    • Automatic validation of the cycle and processing phases:
      • Heating phase
      • Pasteurization holding phase
      • Time above 58°C
      • Cooling time
    • Traceability can be connected to a blast freezer to monitor and archive cooling and freezing cycles.
  • Decontamination of wet components
    • Automated chemical decontamination cycle (Sanosil).
  • Pasteurization cycle
