Description

Technical Field

[0001] The utility model relates to the technical field of grain grinder components, and more specifically to a blade for a grain grinder. Background Art

[0002] The grain grinder includes a soymilk machine, which is controlled by a microcomputer to fully automate the preheating, beating, boiling and delayed boiling processes, making the soymilk more nutritious and more fragrant.

[0003] At present, grain grinders need to use blades when crushing grains, but commonly used blades have a small crushing area, a relatively simple function, and are not easy to clean after use.

[0004] For example, a grain grinder disclosed in publication number CN201384041Y includes a machine head, an anti-overflow electrode, a motor, a temperature sensor, an electric heater, a barrel, a grinding blade, and a deflector. The outside of the lower cover equipped with the motor where the machine head contacts the barrel is provided with a metal layer.

[0005] It can be seen from the above-mentioned public scheme that the contact area between the grinding blade and the grain during rotation is small, which reduces the grain crushing efficiency. In addition, it only has the function of rotational crushing, which is a single function. In addition, the grinding blade is fixed to the motor shaft and thus connected to the machine head, which makes it inconvenient to take out and clean, thereby reducing the cleaning efficiency.
