Abstract

The utility model discloses a rice mill sieve. The cross section of the sieve is a regular polygon, the number of sides n is greater than or equal to 5 and is an integer. Strip-shaped meshes are arranged on the sieve and are oblique, and an included angle formed by the strip-shaped meshes and a sieve axis is 18-25 degrees. Due to the fact that the cross section of the sieve is the regular polygon, path distances from rice to inner walls of different places on the same side of the sieve are different, and turning-over power to different rice is different. On the whole, total rice turning-over times at the same time period are increased compared with the prior art, and the times of frictional force production caused by impact are increased, thereby enabling the rice to be easily husked and to be clean.

Description

A rice mill sieve

technical field

The utility model relates to the improvement of the rice mill technology, in particular to the screen on the rice mill.

Background technique

The process of rice milling is the process of removing the husk of rice to form bran and separating the bran from the white rice after husking. Its working process is as follows: the rice first enters the box through the leaking trough assembly and contacts the rice roller, the spiral part on the rice roller pushes the rice into the rice milling chamber for rice milling, and then presses out the white rice from the other end. The rice milling room is composed of a screen and a rice roller that extends into the screen. During the high-speed rotation of the rice roller, the rice is continuously bumped and turned over by the rice roller and the screen. During the collision, friction is generated to realize husking. The faster the paddy is turned, the greater the probability of impact with the rice roller and screen, and the easier the husking. The cross-section of the traditional rice mill screen is circular, surrounded by two upper and lower semicircular screens, and the mesh holes on the screen are long strips along the axial direction of the rice roller. This sieve makes the collision and turnover of the paddy relatively uniform on the whole, which is unfavorable for improving the turnover speed and the cleanliness of husking of the paddy.

Contents of the invention

Aiming at the above-mentioned deficiencies in the prior art, the purpose of this utility model is to provide a novel rice mill screen that solves the disadvantages of traditional rice mill screens in improving the turning speed of rice and the cleanliness of shelling.

In order to achieve the above object, the technical solution adopted by the utility model is as follows: a screen for a rice mill, characterized in that: the cross section of the screen is a regular polygon, and the number of sides n≥5 is an integer.

Further, a strip mesh is provided on the screen, and the strip mesh is inclined and has an included angle of 18-25° with the screen axis.

The screen is surrounded by two symmetrical pieces.

In the utility model, since the section of the screen is a regular polygon, the distance between the paddy and the inner wall at different places on the same side of the screen is different, so the turning force of different paddy is different. Generally speaking, the total number of flipping of paddy in the same time period Compared with the increase in the prior art, the number of times of the friction force generated by impact is increased, so that the husking of rice is easier and cleaner.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to Fig. 1 and Fig. 2, as can be seen from the figure, the utility model rice mill screen 1, its cross section is a regular polygon, its number of sides n ≥ 5 and is an integer.

A strip-shaped mesh 2 is provided on the screen, and the strip-shaped mesh is inclined and has an included angle of 18-25°, preferably 20°, with the screen axis.

The screen 1 is surrounded by two symmetrical pieces.

In the utility model, since the section of the screen is a regular polygon, the distance between the paddy and the inner wall at different places on the same side of the screen is different, so the turning force of different paddy is different. Generally speaking, the total number of flipping of paddy in the same time period Compared with the increase in the prior art, the number of times of the friction force generated by impact is increased, so that the husking of rice is easier and cleaner.

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modifications or equivalent replacements of the technical solutions without departing from the purpose and scope of the technical solutions of the utility model shall be covered by the claims of the utility model.
