Product catalog summary

Overview of Aseptic Systems:
The document discusses the Sterideal® Ohmic system by JBT for aseptic treatment of high and low acid products. It highlights the use of ohmic heating, which involves passing an electric current through the product, causing heat generation due to electrical resistance. This method ensures rapid and uniform heating without structural damage to the product.

Ohmic Heating Advantages:

Minimizes structural damage and retains nutritional value.
Prevents protein denaturation at high temperatures.
Ensures homogeneous treatment, especially for liquid foods with large particles.
Fast heating with minimal temperature error.
Low pressure drop and no fouling due to absence of hot walls.

Working Details:
The system adjusts power based on product conductivity to maintain temperature set points. It is self-protected, shutting down upon detecting electrical anomalies and restarting automatically.

Product Applications:

Suitable for products with dices, liquid eggs, fruit and vegetable juices, isotonic drinks, and soups with meat.

Industrial System Features:

Modular and flexible, suitable for throughput from 1000 l/h to 20000 l/h.
Temperature profiles range from 65°C to 135°C, extendable up to 150°C.
Can be integrated with existing systems for enhanced capacity and quality.

Advantages of Ohmic Heating:

Preserves color, texture, and taste.
Faster process temperature achievement and uniform heating.
Reduced fouling and maintenance costs.
High energy efficiency (92-95%).
Minimal mechanical damage to food particles.
Flexibility to process various products with minimal system modifications.

Contact Information:
JBT provides contact details for their offices across Europe, North America, Asia Pacific, South Africa, and Latin America.

Additional Services:
JBT offers PRoCARE® services for maintenance, ensuring cost-effective and timely upkeep of systems.
