Scraped surface heat exchanger Mondomix

liquid/liquidstainless steelsanitary

Overview
The Mondomix Mondotherm is a scraped-surface heat exchanger designed for continuous heating or cooling of viscous liquids and liquid products containing small particles that are unsuitable for plate or tubular exchangers.

Highlight features

• Vertical jacketed vessel: product enters at the bottom and is lifted by an internal pump.
• Continuous scraping: scraper removes product from the heated/cooled wall to maintain heat transfer and control viscosity.
• Hygienic stainless-steel construction: all product-contact surfaces are stainless steel and designed without dead legs.
• Mobile installation: mounted on three stainless-steel legs for flexible in-line placement.

How it works
The product is fed to the vessel bottom, pumped upward while a rotating scraper continuously removes build-up from the jacketed wall. Heat is transferred through the jacket to perform controlled heating or cooling before the product exits at the top.

Key benefits

• Compact vertical footprint reduces floor space and prevents air entrapment.
• Allows gentle thermal treatment of viscous creams and particle-containing masses.
• CIP-capable cleaning: cleaning fluid can be pumped through the unit without dismantling.

Application possibilities

• Fat creams and other high-viscosity confectionery masses.
• Continuous processing of viscous liquids with small particles where plate/tubular exchangers fail.

Typical process chain (example: marshmallow production)

• Premixing — dispersion of sugar, water and syrups.
• Cooking — batch heating to target temperature.
• Mixing and cooling — cooling and addition of whipping agents.
• Buffering and tempering — temporary storage and temperature control.
• Aerating — incorporating gas to achieve desired texture.
• Color/flavor injecting — dosing and mixing colors or flavors.
• Forming — depositing or extruding onto starch bands.
• Starch handling and cutting — final finishing and cutting.

Services and training

• Performance assessment workshops, spare parts and wear parts supply, and operator training.
