Description
Technical Field
[0001] This utility model belongs to the field of grain processing technology and relates to a grain dehulling system suitable for polished rice processing. Background Technology
[0002] In the traditional rice processing workshop, the hulling and brown rice separation section first transports the cleaned rice through conveying equipment and pipelines to the hulling machine for dehulling, turning the paddy into brown rice. Then, the brown rice is transported again through conveying equipment and pipelines to the brown rice separator for sieving.
[0003] This traditional process has advantages such as simplicity and economy, but it places high demands on the quality of the cleaned raw grains and the performance of the equipment. It requires low awn content in the cleaned paddy and high hulling efficiency in the rice huller. However, in reality, rice hullers cannot achieve 100% hulling, resulting in some unhulled paddy mixed with brown rice after hulling. Therefore, a paddy-brown rice separator is needed to separate the unhulled paddy from the brown rice. However, during the separation process, many unhulled paddies still have awns, which the paddy-brown rice separator cannot remove. This eventually leads to screen blockage, affecting screening efficiency and directly impacting subsequent processing stages.
