(B) Conventional technology In a hulling plant configured as described above, when wheat is mixed in the brown rice that has been sorted by the oscillating sorter for sorting mixed rice,
Conventionally, an oscillating sorter for selecting different types of wheat is installed in parallel in the downstream stage of the oscillating sorter to remove mixed wheat.

That is, the configuration is as disclosed in Japanese Patent Application Laid-Open No. 167454/1983.

(c) Problems to be solved by the invention However, with this configuration, a oscillating sorter for selecting different types of rice must be installed in the subsequent process of the mixed rice oscillating sorter in order to remove mixed grains. , the installation area becomes large due to the installation of two oscillating sorters, and the power consumption increases.
There are disadvantages such as high cost.

Therefore, the present invention was specifically invented to select and remove wheat without installing a separate oscillating sorter for selecting different types, thereby avoiding the above-mentioned drawbacks. 2) Means for Solving the Problems The present invention, as a method for achieving the above-mentioned object, provides a hulling machine that dehulls paddy and wind-sorts the scraped material, and It consists of a shaking sorter for sorting mixed rice that sorts mixed rice of brown rice and paddy.The brown rice sorted by the shaking sorter is taken out through a brown rice take-out route, and the unsorted mixed rice is shaken through a mixed rice conveyance route. In a system that returns paddy to a dynamic sorter and returns it to a huller through a paddy transport route to complete the hulling and sorting process, a plurality of different types of tanks are installed and a switch that operates intermittently on the paddy transport route is used. A hulling and sorting process in which a valve is provided to communicate with one of the different types of tanks, and when the full capacity of the different type of tank is detected, the supply of raw paddy to the huller is stopped, and the contents of the different type of tank are taken out or returned to the huller. and a re-sorting process in which the brown rice removal route is connected to the other tank of different types by an appropriately operated switching valve, and the grains in the tank of different types are re-sorted by passing through the huller. There is a list that I tried to remove.

(f) Function With this configuration, the raw rice is debonded by the huller, and the scraped material is wind-selected to remove dust such as rice husks and light husks, and after this removal, the unbonded rice is The mixed rice of rice and paddy is sorted by a shaking sorter for sorting mixed rice.

The brown rice that has been sorted by the shaking sorter is taken out from the brown rice take-out route, the unsorted mixed rice is returned from the mixed rice conveyance route to the shake sorter and re-sorted, and the paddy is transferred to the paddy conveyance route. The rice is returned to the huller and re-weighed.

In this case, if wheat is mixed in, most of the wheat will be mixed in the paddy that passes through the huller and is sorted by shaking, and the mixed rice will contain some wheat or brown rice. A small amount of wheat is now mixed in the paddy, and the wheat mixed in the paddy is also stored in one of the different types of tanks by a switching valve that operates intermittently during the process of returning the paddy from the paddy transport route to the huller. When this foreign tank becomes full, this is detected and the supply of raw paddy to the huller is stopped, and the contents of the foreign tank are taken out of the machine or returned to the huller and shaken. The wheat mixed in the brown rice is then sent to the sorting machine where it is hulled and sorted again, and the wheat mixed in the brown rice is stored together with the brown rice in the other tank of different types by the appropriate switching operation of the switching valve in the process of being taken out from the brown rice extraction route. be done.
