STEAM & AIR BENEFITS

Lagarde Autoclaves is convinced that social progress, workers safety and environment protection are crucial for a sustainable and long-term economic growth. Among the different retort technologies, Full Water Immersion and Hot Water Spray (the historical processes), are commonly offered by manufacturers throughout the world: simple to manufacture, those processes face the heavy problem of over-excessive consumption of the precious resources that are steam and water. The generation and use of which are harmful to the environment.

This is why, when we design and offer a Lagarde Steam & Air retort, our designers and engineers’ goal is to make the greenest of retorts (autoclaves). Also every new Lagarde retort is built using highly recyclable materials, free of many of the harmful substances present in many other retorts from other manufacturers.

Lagarde’s engineers can also help you design your sterilization cycle and use the Lagarde Steam & Air process, in order to maximise energy efficiency and minimize the carbon footprint of your retort (autoclave).

The result is exactly what you could hope for: the greenest family of retorts we’ve ever made !

By becoming the proud owner of a Lagarde Steam & Air retort, you will benefit from:

Money savings

Use only what you need : steam consumption optimised thanks to direct steam injection.
– No intermediate fluid to heat first before heating up your products.
– Very quick temperature come-up time to reach your set temperature.

Excellence

As mentioned in the scientific litterature, the Lagarde Steam & Air system is the only process capable of dealing with all type of packaging, thanks to the combined advantages of a gaz property, forced circulation with the fan, and the Lagarde soft cooling system. (Source: “La conserve appertisée”, J. Larousse, p.584)

Security

Temperature accuracy with independent pressure and packaging shape (controlled forced ventilation)
– No umbrella effect as opposed to water spray systems
– No thermal shock thanks to the Lagarde soft cooling system: accuracy up to 0,2°C.
– No risk of the spray nozzles becoming obstructed during heating, and/or sterilisation holding time.

A few figures highlighting the main advantages of the Lagarde Steam & Air process VS Water based processes:

  • Steam savings, electricity and water: energy savings from 30% to 80%
  • Faster cycle inducing higher productivity:
    • Come-up-time shorter from 20% to 40%
    • Sterilization time reduced by 10% to 20%
  • Fluid contact zones on the packaging 2 to 5 times higher
  • Required boiler capacity 30% to 50% lower

Lagarde Steam & Air compared to Water processes :

This study, undertaken by an American University, clearly shows the consumption differences between the technologies:
(Results presented at the US institute of thermal process by Rieks Bruins from the Rutgers University in 1995).

The above study states the Steam & Air technology allows savings of up to 100% on utilities compared with other processes.
These results are easily explained by a few basic scientific data. View physical evidence.
