Sterideal Ohmic Heat Exchanger

The Sterideal Ohmic Heat Exchanger preserves food quality by minimizing structural damage and preventing protein denaturation. Unlike conventional methods, Ohmic heating offers rapid, precise temperature control, avoiding overheating and particle damage. The system adjusts power based on electrical conductivity, ensuring self-protection by shutting down in anomalies and restarting quickly.

The Sterideal Ohmic Heat Exchanger minimizes structural damage to products, preserving their nutritional value and ensuring high-quality processing in a short operating time. Research indicates that ohmic heating prevents protein denaturation at high temperatures, providing homogeneous treatment by volumetrically heating the entire mass of food material.

Unlike conventional heat exchangers, ohmic heating avoids overheating of liquid foods with large particles, as it has a low heat transfer rate by conduction. It offers rapid heating, achieving a temperature increase of 40-50°C with a maximum error range of 0.2°C in seconds.

Its heating systems are not prone to fouling, have a low pressure drop, and avoid damaging particles, distinguishing them from scraped surface heat exchangers. The system operates by selecting an initial voltage based on the product's electrical conductivity, continuously adjusting power to maintain temperature set points. Additionally, the system is self-protected, shutting down in the presence of anomalies in electricity parameters and quickly restarting afterward.
