Abstract

PURPOSE:To prevent grain from crushing and generating crushing sound even if the clearance gap between a screw casing and screw is reduced by forming a notching section on the screw corresponding to the peripheral section n the down stream side of the lower end opening of a supply port in the grain transferring direction. In this case grain is thrown from grain supply hopper into the supply port and flow toward the screw. CONSTITUTION:A notching section 34 is formed on the screw 30 corresponding to peripheral position 33 on the down stream side of the lower end opening section of a port 31 in the grain transferring direction. In this case grain is through from a hopper 1 into the supply port 31 and flows toward the screw casing 29. Even if the clearance gap between the screw casing 29 and screw 30 is reduced resulting in the reduction of the quantity of remaining grain, this constitution can prevent grain from crushing and generating crushing sound.

In the conventional screw feeder, as shown in FIG. 6, a screw is rotated 3 degrees in a cylindrical screw casing 29, and feed is fed from a supply hopper 1 to an input port 31 opened at one end of the screw casing 29. The conveyance is transferred to the outlet 32 at the other end of the screw casing 29. The screw feeder has a motor 2 that drives a screw 30.
It is used in various fields because the flow rate can be varied over a wide range by implementing the rotational speed control described in No. 3.

Problems to be Solved by the Invention When brown rice is to be transferred using a screw feeder, the brown rice A to be transported is put into the supply hopper 1, and the brown rice A is cut out one after another by the screw 30 from the input port 31 and then transferred to the discharge port. Transported towards 32. If the gap g between the screw casing 29 and the screw 30 is not made small, the untransferable brown rice A will remain at the bottom of the screw casing 23 at the end of the conveyance stage, so it is desirable to make the gap g small. In this case, there is a problem in that brown rice is pinched between the corner 33 at the lower end of the input port 31 and the screw 30, and the pinched brown rice A breaks and becomes "waste rice". In this case, when the brown rice A is crushed, a crushing sound is generated and the feeling of use is poor.

While steps (a-5) and (a-8) are repeatedly executed, brown rice is not additionally supplied to the polishing cylinder 2, so the feed roll 4 does not push brown rice into the polishing chamber 25.
The internal pressure of the whitening chamber 25 does not rise to the specified value required to push down the opening regulating plate n against the bias of the compression spring 21. Therefore, during the period when the operation of the screw feeder 3 is stopped, brown rice is not discharged from the outlet 2B, and as shown in FIG.
The material is sufficiently polished between the whitening roll 5 and the net 15 over a set time t.
