Ohmic heat exchanger Sterideal®

slurry-to-slurrysanitaryfor viscous liquids

Overview

• Very fast heating and rapid come-up time
• Uniform temperature distribution across the pipe section
• Extremely accurate temperature control for thermo-sensitive products
• Reduced product speed to minimize damage and lower pressure drop
• Full drainage to avoid residual product and CIP chemical retention
• Multiple configurations and process control options to meet critical temperatures
• Compact footprint for minimized floor space

How it works
Ohmic heating applies high voltage to the product flowing inside the heat exchange unit so the liquid acts as an electrical resistance and generates heat by the Joule effect. Higher voltage and higher electrical conductivity accelerate temperature rise. In particulated products (e.g. dices), the centre of particles heats at the same rate as the liquid carrier, preventing overheating and preserving product quality.

Applications

• Liquid, semi-liquid, concentrated and high-viscosity products
• Products with fibers or small cells such as purees and soups
• Fruit preparations and jams with pieces
• Soups and sauces
• Suitable for large particles up to 35 mm (1.38 in)
