The main difference between the straight blade and the cross blade of the smoothie machine is the shape and suitable whipping objects.

1. Shape: The shape of the straight blade is like a "one" with a narrow incision width. The cross blade is shaped like a "ten" with a wider incision width.

2. Applicable whipping objects: Slotted blades and cross blades have different effects when cutting materials, mainly due to their shape differences. For example, the cross-shaped blade is suitable for whipping fruits and vegetables with high water content, such as apples, oranges, pears, strawberries, peaches, cucumbers, etc.
