Description

TECHNICAL FIELD

[0001] The utility model relates to rice powder processing technical field, concretely is rice powder processing raw material grinding and crushing equipment. BACKGROUND

[0002] In the rice powder processing process, grinding and crushing the raw materials is a crucial step. The grinding process can refine rice or other raw materials into smaller particles, making them more suitable for subsequent processing steps. Small particles can be more evenly distributed in water, which is beneficial for starch gelatinization and rice powder formation.

[0003] The existing patent No. CN218167287U discloses a grinding device for rice powder processing, which includes a grinding disc and a primary grinding groove. When in use, the rice powder to be ground is input into the primary grinding groove through the feed channels on both sides of the top of the primary grinding groove. Then, the servo motor is started to rotate the rotating grinding disc under the connection of the transmission belt. The rice powder in the primary grinding groove is rolled and ground by the distance between the rotating grinding disc and the inner wall of the primary grinding groove. Then, the ground rice powder in the primary grinding groove is sieved and filtered through the grid at the bottom of the primary grinding groove. Then, the rice powder is input into the secondary grinding groove through the rice powder transmission channel. At the same time, the operation of the servo motor will synchronously drive the oscillating connecting rod to rotate, and then synchronously drive the lifting plate to cycle up and down. The input rice powder is continuously extruded and ground by the extrusion between the lifting plate at the bottom of the lifting plate and the secondary grinding groove. Then, the ground rice powder is filtered through the grid at the bottom of the secondary grinding groove, and then output through the discharge port.

[0004] The above device grinds the rice powder raw materials. The rice powder raw materials enter the secondary grinding groove through the primary grinding groove and the rice powder transmission channel for regrinding. Since the secondary grinding groove can easily accumulate too much, the extrusion rolling may not grind some of the raw materials finely enough, affecting the subsequent processing of the rice powder. Moreover, the rice powder transmission channel is prone to blockage. To solve the above problems, a rice powder processing raw material grinding and crushing equipment is proposed.
