Abstract

PURPOSE:To make the dehulling rate of falling hulled rice approximate to that of sample grains in detecting the dehulling rate of the sample grains from a spiral type mixed rice lifter lifting the falling hulled rice from a dehulling part 1. CONSTITUTION:The falling hulled rice from the dehulling part 1 of a hulling sorter is winnowed to be lifted by a spiral type mixed rice lifter 8 and the lifted mixed rice is collected from grains scattered by a diffusing blade 25. In this case, since sample grains are collected from the grains of the intermediate parts of inner and outer layers, sample grains are collected from both of the unpolished rice distributed on the outer peripheral side of the lifted rice and the grains distributed on the inner peripheral side thereof. Therefore, the dehulling rate of the falling hulled rice of the dehulling part can be made approximate to that of sample grains.

0001

[Industrial Application Field] This invention has a husking section, a wind selection section for wind-selecting the fallen rice that has been hulled in the shedding section, and a wind-selecting section for wind-selecting the fallen rice that has been hulled in the shedding section, and converting the washed-off rice that has been wind-selected in the wind selection section into paddy or brown rice. The present invention relates to a sampling device for a huller and sorter, which is equipped with a mixed rice sorting section for separating and sorting, and a helical-type mixed rice lifting machine.

0002

[Prior art] A husking section that removes the hulls, a wind selection section that wind-sorts the rice that has been removed from the hulling section, and a wind selection section that processes the mixed rice after wind selection in the wind selection section using a helical-lifting method. There is a hulling sorting machine that fries the grain into a mixed rice sorting section, and then separates the mixed rice into paddy and brown rice at the mixed rice sorting section. Among such hulling and sorting machines, there is one that performs sampling to detect the shedding rate of the hulled rice from a helical grain-lifting type mixed rice lifting machine.

[Problems to be Solved by the Invention] When sampling from a prior art spiral-type mixed rice frying machine, sample grains that match the mixing ratio of paddy and brown rice in the mixed rice being fried are sampled. This results in a difference between the pulping rate of the mixed rice and the pulping rate of the sample grains. When adjusting the gap between the rolls, there was a problem in that the gap between the depulling rolls could not be adjusted accurately, resulting in various problems such as damage to the grain.

[0004] Accordingly, the present invention has been developed by observing the grains fried using a spiral grain type mixed rice lifting machine, and it is found that among the mixed rice of paddy and brown rice, the brown rice with a high specific gravity is located on the outer periphery side. This method was invented based on the knowledge that paddy grains with light specific gravity are distributed on the inner periphery side during frying. This is intended to reduce the difference between the hulling rate of fried mixed rice and the hulling rate of sample grains.

In addition, grains mainly consisting of unhulled rice after sorting sent to the discharge side end of the rotary sorting tube 11 flow into the upper scooping vane tube 21, where they are pumped up into the paddy return gutter 22 and removed. It is reduced to the poop section 1 and subjected to the pooping action again in the poop section 1.

[0022]

Effects of the Invention As explained above, when collecting sample grains from the mixed rice frying machine 8 for detecting the shedding rate of dropped rice, the grains in the middle part of the inner and outer layers are splashed by the diffusion blades 25. Since sample grains are collected from both the brown rice grains distributed on the outer periphery side of the fried grain, which has a higher specific gravity, and the paddy grains that are distributed on the inner periphery side, which has a lower specific gravity. , it is possible to approximate the shedding rate of the scraped rice in the shedding section 1 and the shedding rate of the sample grains, and it is possible to improve the accuracy of the detected hulling rate.
