STOCK - Steam Water Spray Retort
STOCK specializes in providing advanced solutions for pasteurization and sterilization using steam-spray retort systems, designed specifically for modern packaging flexibility. With over a century of expertise and continuous innovation in automated systems, STOCK caters to the needs of clients worldwide by offering custom, economically efficient, and high-performance solutions that ensure product quality and process fidelity. The steam-spray process is optimal for applications where steam and water consumption are priorities, providing direct contact with container materials. By directly mixing steam with finely sprayed water droplets, a uniform and highly efficient heat transfer environment is created. This ensures rapid heating and cooling, reduces energy use, and maintains safe counterpressure control. It is suitable for various cage sizes and types, and offers precise temperature management with less than 1°C variation within the retort. The system can also be integrated with heat exchangers for efficient cooling and water recovery.
Today's markets continuously demand new packaging materials for the presentation of shelf stable foodstuffs. Custom tailored solutions, convincing with regard to economics, performance and quality, are more important than ever. Based on more than 100 years of experience and a steady, innovative development of automated systems, STOCK offers individually designed solutions to customers. First-class references around the globe rely on this proven Technology.
Now STOCK Retorts are manufactured in India by STERDILL with technical Know-how from Germany.
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.
