Scraped surface heat exchanger for high-viscous products
For processors of high-viscosity spreads, efficient heat transfer is crucial for achieving desired texture and consistency, whether cooling or heating during pasteurization and crystallization processes.

Processes High-Viscous Food Products Efficiently
The RONOTHOR RT from RONO is a sophisticated high-pressure scraped surface heat exchanger designed specifically for food processing applications requiring precise temperature management. Powered by an SEW Type FAF gear and up to 75 KW motor, this unit efficiently processes high-viscous products like margarine, butter, and shortening. Its modular design allows for integration of up to six units per frame, providing flexibility and scalability in your production line.
The RONOTHOR RT excels in heating, cooling, pasteurization, and crystallization, drastically enhancing the quality of spreadable margarine, bakery shortening, and similar products. With a focus on operational efficiency, the unit accommodates various cylinder sizes and scraper configurations to suit your production needs. The equipment supports a range of heating and cooling media, including freon, ammonia, and glycol, ensuring versatility.
Manufactured in Germany, the unit’s solid design includes a chrome-plated mild steel or optional stainless steel construction, defensively preparing it against corrosion. The RONOTHOR RT is equipped with an electronic level control and a BUS system for easy integration and operation monitoring. Maintaining the equipment is simplified with its hygienic design, and servicing is user-friendly with readily available spare parts and support.
