Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a circulation drying device that repeatedly sorts soybeans during the circulation drying process.

(b) Conventional technology Conventionally, the device for drying grains was, for example,
This is a well-known method known from Japanese Patent No. 19271, etc., and in the case of soybeans, the sorting surface of an inclined sorting belt is rotated toward the higher side of the inclination to remove irregular grains such as broken grains and flat grains. An apparatus for sorting into granules and sized particles is disclosed in Japanese Patent Application Laid-open No. 163472/1983.

In this way, drying of soybeans harvested in a raw state from the field and sorting after drying are each performed using separate devices.

(c) Problems that the invention aims to solve As mentioned above, when soybeans are traditionally harvested, drying and sorting after drying are performed separately using individual devices; Even unnecessary irregular grains are completely dried, resulting in wasted drying, and when dried, the grains become small, and the fractured surfaces of broken grains and the flat surfaces of flat grains produced by threshing are reduced, and they are removed from the sorting belt. It becomes difficult to stop and rolls easily, reducing the sorting effect.

Therefore, from this point of view, the present invention eliminates the waste of drying as much as possible, and also performs drying and sorting at once while performing a good sorting action between irregular grains such as broken grains and flat grains and regular grains. It was devised for the purpose of providing a device that can

(d) Means for solving the problem In order to achieve the above object, the present invention installs an endless sorting belt in an inclined state near the bottom of the lower outlet of the dryer, and the sorting belt The top surface can be rotated towards the high side of the slope,
In addition, the lower inclined side of the sorting belt is connected to the upper part of the dryer via an elevator, so that sorting can be repeated in the process of circulation drying.

(E) Effect According to this configuration, soybeans harvested in a green state are circulated and dried completely, but in the process of being completely dried, they are repeatedly sorted by the sorting belt, and unnecessary broken particles and Irregular grains such as flat grains are picked out by knowing the high slope of the sorting belt, and the removed particles are fed to the dryer by an elevator that knows the low slope, and are removed by the sorting belt each time during the drying cycle. Unnecessary irregular grains are then removed.

In addition, since the soybeans supplied from the lower outlet of the dryer onto the sorting belt are still in the process of drying, the irregularly sized fractured surfaces and flat surfaces of the soybeans are larger than those after drying is completed. The flat grains are reliably stopped on the sorting belt, and the rotating sorting belt determines the height of the inclination and is taken out and sorted.

(F) Embodiment The present invention will be explained below based on the embodiment shown in the drawings. Fig. 1 shows a side sectional view of the whole, and A is an elevator, which is installed vertically with an elevator belt 2 equipped with a bucket belt 6. Receiving hoppers 3 and 4 are installed on both sides of the lower part of the elevator A, and an inclined gutter 5 is installed on the upper part.
Configure by connecting them.

B is a dryer, and the gutter 5 is installed in the upper part of the dryer B.
The lower end of the dryer B is connected to the lower end of the dryer
A small lower outlet 1 is formed to discharge the soybeans downward little by little.

C is an endless sorting belt, and the sorting belt C is tilted so that the upper side of the inclined side is wrapped around the drive roll 7 and the lower side of the inclined side is wrapped around the idler roll 8, so that the upper surface is in the C direction, that is, the inclined high side direction. The lower outlet 1 is positioned above the middle part of the sorting belt C in the inclined direction. One receiving hopper 4 of the elevator A is visible below the lower inclined side of the sorting belt C, and a receiving container 9 is visible below the higher inclined side of the sorting belt C. .

Therefore, when freshly harvested soybeans are put into the receiving hopper 3, they are raised in the elevator A by the bucket 6 and thrown into the dryer B through the gutter 5, where they are stored. During this time, the soybeans that descend under such conditions are dried, and the soybeans that fall from the lower outlet 1 are placed on the sorting belt C.

The sorting belt C rotates as shown by arrow C, and irregular grains such as broken grains and flat grains are rolled on the sorting belt C with their fractured surfaces and flat surfaces engaging the upper surface of the sorting belt C. Without moving, it is sent to the inclined upper side and received into the receiving container 9. On the other hand, round, high-quality grains roll on the inclined upper surface of the sorting belt C and are received as they are from the inclined lower side. It is received in the hopper 4, raised again by the elevator A, and supplied to the dryer B. In this way, the drying by the dryer B and the sorting by the sorting belt C are repeated to effect circulation drying.

(g) Effects of the invention As explained above, the present invention has an endless sorting belt mounted in an inclined state near the bottom of the lower outlet of the dryer, and the sorting belt has its upper surface tilted toward the upper side. In addition, the lower inclined side of the sorting belt is connected to the upper part of the dryer via an elevator, so that when the raw soybeans are completely dried, the sorting belt Sorting is repeated to remove unnecessary broken grains and irregular grains such as flat grains, and the removed grains are supplied to the dryer, where they are sorted by a sorting belt each time during drying circulation. In addition, since the soybeans sorted by this sorting belt are still in the process of drying, the shape of the fractured surfaces and flat surfaces of irregular grains is much smaller than that of the soybeans after drying. Flat grains with large fractured surfaces and flat surfaces are stopped on the sorting belt and do not roll, so the sorting action can be carried out well, and drying and sorting can be carried out effectively at the same time. It was finally possible to do so.
