It is very important to ensure that the container has sufficient depth when using a hand blender. If the container is too shallow, ingredients may splash out during the mixing process, causing waste or dirtying the surrounding environment. In addition, shallower containers may also limit the range of motion of the mixing head, resulting in uneven mixing and even unnecessary pressure on the machine. A deeper container can ensure that the mixing head moves fully in the food, achieving better mixing effect and avoiding food splashing. A container of moderate depth can help hand mixers process ingredients more effectively, especially when dealing with liquid or soft foods such as soup, sauce, and puree. A container of appropriate depth can ensure that the mixing head is immersed in enough ingredients to ensure even mixing. Overall, using deeper containers helps improve mixing efficiency and ensure that ingredients are stirred more evenly.
