Cutting ring assembly for rice mill

Abstract

The present invention relates to a cutting ring assembly for a rice mill in which a spacing ring including at least one or more inducing protrusions is alternately disposed between cutting rings to smoothly and forcibly transfer rice grains in the direction of a discharge hole of the rice mill without damaging the rice grains. The cutting ring assembly for the rice mill according to the present invention includes a support shaft having a hollow cylindrical shape and in which at least one key groove is formed in each of an inner circumferential surface and an outer circumferential surface in a longitudinal direction, a plurality of cutting rings coupled to the support shaft, and a plurality of spacing rings coupled to the support shaft and disposed between the cutting rings. Also, the cutting rings have a ring shape having a predetermined thickness and a plurality of channel-shaped cutting passages, which connect both side surfaces of the ring to each other so that rice bran is cut while the rice grains pass therethrough, in an outer circumferential surface thereof, and a key groove connection protrusion formed in an inner circumferential surface thereof is inserted and coupled to the key groove formed in the outer circumferential surface of the support shaft. Also, the spacing rings have a ring shape having a predetermined thickness and includes at least one inducing protrusion in an outer circumferential surface of the spacing ring, and a key groove connection protrusion formed in an inner circumferential surface of the spacing ring is inserted and coupled to the key groove formed in the outer circumferential surface of the support shaft.

Description

technical field [0001] The invention relates to a cutting ring assembly for a rice mill. More specifically, it relates to alternately disposing spacer rings with at least one guide protrusion on the outer peripheral surface between the cutting rings and the cutting rings so that the rice grains can be smoothly conveyed by pressure to the discharge port of the rice mill without Broken rice mill cutter ring assembly. Background technique [0002] Generally speaking, the rice harvested in the paddy field is called brown rice after removing the coarse bran (the whiteness of the rice is 100, and the whiteness is ±20). And, the rice which removed the rice bran layer including the peel, the seed coat, the perisperm, and the aleurone layer which is the outermost layer of brown rice is called white rice. White rice is divided into 50% hulled, 70% hulled, and 100% hulled rice according to the degree of whitening. As mentioned above, the process of separating rice bran (rice bran) f...

AI Technical Summary

Problems solved by technology

In addition, there is a problem that the rice bran cannot be completely removed and the rice grains cannot be sufficiently cooled during the milling process due to the insufficient amount of air supplied through the hollow shaft and the cutout portion of the spacer
