Concentrate heater for dairy spray dryers
Achieve precise temperature control in dairy powder production with a concentrate heater that gently preheats liquid milk feeds, enhancing final product consistency and quality while optimizing spray dryer performance.

Preheats Concentrated Milk for Uniform Spray Drying
The GEA SaniX Concentrate Heater is engineered to preheat concentrated milk feed with precision before it reaches the spray dryer, ensuring uniform temperature for optimal spray drying results. Integrated into the GEA dairy spray dryer systems as standard, this equipment plays a critical role in maintaining the integrity and functionality of dairy and nutritional powders. It employs hot water heating, offering a cost-efficient and gentler approach compared to traditional steam systems, effectively reducing energy use.
Suitable for the dairy and food industries, the SaniX Concentrate Heater is versatile, processing a range of end products such as whole milk powder and protein-fortified milk powder. Its spiral, dual-channel heat exchanger design ensures that the milk feed is evenly heated, safeguarding against protein denaturation and enhancing powder dispersibility.
This process is supported by a high heat transfer coefficient and turbulent flow, maintaining consistent temperature control. Fully compliant with EHEDG guidelines and available with USDA / 3A certification, the SaniX equipment is compatible with third-party systems and configurable to meet specific processing needs. Its design facilitates continuous operation and easy integration within existing production lines, supporting both efficiency and product quality.
