Screening device for selenium-rich rice

Abstract

The invention discloses a screening device for selenium-rich rice. The screening device for the selenium-rich rice structurally comprises a screening device body, a particle sieve device, an integrated sieve frame and a bottom sieve device, wherein the screening device body is mounted on the integrated sieve frame, and the screening device body is connected with the particle sieve device in an assembling mode. According to the screening device for the selenium-rich rice, left-right end distribution type screening and shaking of large-particle rice and small-particle rice are carried out at a top sieve plate during screening of the rice, large particles are processed and screened at the particle sieve device, small particles and impurities are screened on an undersize sieve device, and finally the impurities are divided into two parts and are screened and separated at an inner structure dust collector and the bottom sieve device correspondingly; and large-particle-shaking feeding type screening can effectively realize fine processing of the complete large particles, fine processing of the small particles and separation and screening of the impurities are separately achieved, so thatthe effective separation of the impurities such as empty shells, crushed straws, sandy soil, rice froth and grass seeds is achieved in a targeted manner, later processing and utilization of the impurities are facilitated, the screened rice is not doped with the impurities, and high-quality fine processing of the rice is realized.

Description

technical field [0001] The invention relates to the field of rice screening, in particular to a screening device for selenium-enriched rice. Background technique [0002] Rice is processed from rice. During the processing, it is necessary to sieve the impurities on the rice. When sieving the rice, it is necessary to filter out the impurities such as empty shells, broken stems, sand, rice foam, and grass seeds mixed in the rice. Separation is convenient for the later processing of rice, and is also conducive to the high-quality processing of rice in the later stage. [0003] In the existing technology, when performing large-scale rice screening, the screening of rice impurities is realized by shaking a large number of sieves at one time. The effective separation of other impurities makes the sieved rice still doped with some impurities, which makes it impossible to achieve high-quality finishing of rice.

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the deficiencies in the prior art and provide a screening device for selenium-enriched rice to solve the problem of screening rice impurities by shaking a large number of sieves at one time when performing large-scale rice screening. During the screening process, the effective separation of impurities such as empty shells, broken rods, sand, rice foam, and grass seeds cannot be achieved in a targeted manner, so that the rice after screening is still mixed with some impurities, and high-quality finishing of rice cannot be achieved.
