The blade design and shape of a kitchen grinder is one of the key factors that determine its performance, directly affecting the grinding speed, effect and overall reliability of the equipment.

The shape of the blade has a significant impact on the grinding effect. Different shaped blades are suitable for different types of ingredients and grinding needs. Some kitchen grinder designs use multi-edged blades to make grinding more even and help achieve a finer grinding effect. Other designs may choose a single-edged design with a sharp blade edge, suitable for situations where faster sharpening is required. Therefore, in blade design, manufacturers need to carefully design the shape of the blade to maximize the grinding effect based on the kitchen grinder's intended use and user needs.

The sharpness of the blade is also crucial to the performance of a kitchen grinder. Sharp blades make it easier to cut and grind ingredients, improving work efficiency. Therefore, during the manufacturing process of the blade, the sharpness of the blade needs to be precisely controlled to ensure that it can remain sharp during long-term use, which not only improves the grinding effect, but also reduces power consumption and wear.

The arrangement and number of blades also directly affect the performance of the kitchen grinder. Some kitchen grinders use a multi-layer stacked blade structure to improve grinding efficiency and allow more ingredients to be ground quickly. On the other hand, some designs may be more focused on fine grinding of specific ingredients and therefore feature a more precise and complex blade arrangement. This differentiated design can meet the needs of different users, allowing the kitchen grinder to perform well in different scenarios.
