Description

Description: “Industrial field of application” The present invention relates to a grain conditioning device.

"Prior Art" The process of processing the dehulled rice from rice and carefully selecting the brown rice obtained and packing it into bags has been conventionally performed as shown in FIG. That is, after first drying the paddy, it is sent to the paddy huller, and the resulting brown rice is supplied to a grain adjusting device having a sorting function for sorting, and after removing small grains, the grain is weighed into a bag. It was to be packed.

In such a processing method, the grain adjusting device can be selected without being particular about the processing capacity of each machine in the previous step, and the one having only the selecting function is used.

"Problems to be Solved by the Invention" However, the grains after the drying process contain a large amount of dust such as straw chips at the time of threshing, and small grains are also mixed without being sorted. Therefore, if such grains are supplied to the hulling device as they are, not only is there a problem that the hulling device does not exhibit its full capacity and wastes power, and in the final adjusting step. However, there is a problem in that the ability of the grain adjusting device is hindered and dust and the like cannot be removed sufficiently.

Further, in such a conventional adjustment method, a close and organic cooperative operation is not performed in each step, and each step is separated depending on the capability of each device or apparatus.

The present invention has been made in view of such problems in the related art, and by interposing a cereal adjustment device that simultaneously and concurrently processes a plurality of adjustment processes having different functions, a hulling device It is an object of the present invention to provide a grain adjusting device capable of fully exerting the function of (1), having no waste of power, and obtaining high-quality refined grains without dust and the like.

“Means for Solving the Problems” The gist of the present invention for achieving the object is as follows. (1) A method for removing small grains and dust from dried grains in the same outer shell.

"Operation" The dried grain is supplied to the grain supply means of the first grain adjusting section of the grain adjusting device which is the grain adjusting means.

While the supplied grain is being sent upward by the fried helix, the airflow blowing out from the many small holes provided in the cylinder of the fried helix blows off the dust and the like mixed in the grain. Then, it passes through the adjusting mesh and is discharged to the outside by the dust removing means. Further, the small grains that have passed through the adjusting mesh are removed outside the body by the small grain discharging means.

In the first grain adjusting unit, the adjusted grains are those from which dust and small grains have been removed, are supplied from the storage tank to the hulling device, and are subjected to the debarking action, and the grains are again subjected to the grain adjustment. It is supplied to the supply part of the second grain adjusting part of the device.

The second grain adjusting unit is provided with an adjusting net body different from that of the first grain adjusting unit, and, for example, refined grains having a desired particle size are received in the storage tank. Note that this second
Also in the grain adjusting unit, since the action of the dust removing means is working, the dust and the like generated during the removing process and the second adjusting operation are completely removed, and the small grains are also removed.
Good quality grain can be obtained.

During the above operation, the discharge port on the storage tank side is open,
The outlet on the side of the intermediate supply unit is closed by each outlet opening / closing means.

Since the grain adjusting device is provided with the grain adjusting means for the first adjusting process and the second adjusting process in the same outer grain body, the grain adjusting device should be operated simultaneously and in parallel in correspondence with the drying process and the removing process. You can

For example, when the grain adjusting device is used, for example, the first grain adjusting unit removes the branch stems of wheat and the like, and the second grain adjusting unit removes the storage tank on the first side when sorting by particle size. The outlet is closed, and the outlet on the side of the intermediate supply section is opened. And
If the unadjusted barley grain is supplied to the first grain adjusting section to operate, the awns, branch and dust etc. are removed to the storage tank on the second side, and the small grain is also removed, and the grain size is reduced. The whole grain of wheat is released.
