Dashers, Mutators, & Blade Shafts
Dashers and mutators fit inside scraped surface heat exchanger cylinders, where they continuously agitate the product and provide the rotational axis for the scraper blades. The dasher and blade shafts play a key role in mixing and churning the product to achieve the desired texture and consistency.
They are manufactured in a variety of sizes and configurations, depending on the application. Most dashers feature pins mounted along the outer casing to secure the scraper blades. As the dasher rotates, the blades remove product buildup from the inner surface of the heat exchange cylinder, ensuring efficient heat transfer and consistent product quality.

Our Repair Process
Each dasher repair begins with a detailed inspection to verify blade pin alignment and thickness, followed by a check for any stress fractures at the base of the pins. All bearing diameters and spline ends are measured to determine whether welding or machining is required. When applicable, spline ends are restored through our precision keyway cutting process.
We then measure bulkheads and inner pins, record TIR readings, and pressure test each unit to confirm that all leaks and cracks have been fully sealed. This ensures the repaired dasher meets proper installation standards and performs reliably in operation.
