Steam-Spray-Counter pressure Retort Concept

When steam and water consumption have highest priority and the container material is suitable for direct contact with Oxygen in the heating phase, the steam-spray process is the optimal solution.

Directly injected steam blends with fine droplets of the water spray and results in an extremely homogeneous heat transfer environment throughout the whole autoclave. As water jets spray into the cages from the sides as well, even and rapid cooling, also of comparatively flat containers, is safely achieved.

Quick heating, uniform heat distribution, rapid and even cooling. Low electricity, steam and water consumption. Safe counterpressure control during all process phases. Optimal operation also with part loads. Assured process fidelity. Suitable for different types and sizes of cages.


» The main advantages of the steam-spray system.

» Only a small amount of process water is required, circulated by a high performance pump.

» Temperature distribution in the retort better than 1oC.

» Cooling in sterile process water (option : heat exchanger) no chlorination required.
