Multi Filling Supply
- The multi filling system allows two or more different fillings to be processed simultaneously, creating more diverse textures and flavor combinations. By using multiple hoppers, the machine can produce advanced filled products such as layered fillings, dual-color fillings, and jam-filled pastries. This flexible filling solution helps manufacturers develop a wider range of products while maintaining accurate filling distribution and stable production quality.

Egg Wash & Sesame Sprinkling
- The egg wash and sesame sprinkling process enhances both the appearance and final baking performance of bakery products. An even layer of egg wash is applied to the surface, creating a glossy finish and improving the golden-brown color after baking. The sesame sprinkling system then distributes sesame particles evenly onto the product surface, adding additional texture and flavor while maintaining consistent product appearance during mass production.
