Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates from the bottom of the rice tank top
The present invention relates to a cereal weighing and feeding device that pneumatically transports milled rice to a rice washer and feeds the milled rice to a middle- stage steamer.

[0002]

2. Description of the Related Art Conventionally, grains cut into a metering box from a hopper and weighed are not sufficiently sliced. Therefore, when a rotary valve having a plurality of chambers is used, the grains are sheared by the inlet and the rotary and are crushed, so that crushed grains are easily generated. In the rotary valve described above, since grains are continuously supplied, when grains in the fixed volume are fed by an air transport pipe, a residual amount is generated, and it is difficult to transport the entire amount measured by the volume. In addition, a grain tank is installed at the top of the machine frame.
And put it in the rice cooker directly below, so it can be supplied to the grain tank
Requires a lot of effort or complicated equipment, and puts rice in a rice cooker
It is necessary to do this, and it is difficult to put the grain in the bottom grain tank.
There was a problem that it was difficult to be suitable for birth.

[0003]

[0008] The present invention is the lowermost hot <br/> path from the fear without air transport causing crushing grain kernels that have been weighed in quantitative basins remaining without quantifying all uppermost Washing
It was delivered to the US unit, and to obtain a cereal metering feeder capable of multimeric rice to <br/> Rukoto without requiring manpower in the middle of the cooking pot.

[0004]

In order to achieve the above-mentioned object, the present invention provides a rectangular hopper for cereals at the lower end of a machine frame ,

It is shorter than the cereal weighing feed to equipment length Saga cylindrical space short tube constituted by cereal metering feeder of the first invention, wherein.

[0005]

According to the present invention, grains are put into the lowermost rectangular hopper 1 and enter the cylindrical rotary tub 3 fitted into the machine box 2 through the rectangular opening 1 ', and the tub 3 is rotated by 180 degrees. The grains determined in the box 3 by the above flow intermittently enter the cylindrical space 4 through the drop guide groove 5 in each box. Soshi
And pressurize and seal the grains in the space 4 from the air suction pipe 8
Entering the rice washing machine 17, just below the rice washing (in the middle of machine frame 9)
Is cooked into the rice cooker 23.

At one end of the space 4, a spiral groove 6 is formed on the outer peripheral surface of a short cylinder 7 shorter than the space 4, and the spiral groove 6 enters the groove 6 and the remainder remains in the guide groove 5. In that state, the space 4
The cereals in the space 4 are transferred from one end to the other end by sucking air from the other end to the next process side by the air suction pipe 8. That is, a vortex (Karman vortex) is generated immediately after the short cylinder, and the kernel is not retained in the space 4 due to the grain being caught in the vortex. It also has one supply port 3 '
Since the weighed grains enter the cylindrical space 4 intermittently at each rotation of the cylindrical rotary basin 3 comprising chambers, the helical grooves 6 and the cylindrical space 4 are not clogged and the kernels are discharged by an air flow. And leave no kernels.

[0007] In addition, the rectangular shape of the rotarySupply port
The longitudinal direction of 3 'and the rectangular opening 1' of the hopper 1 are longitudinal.
Since the direction is slightly oblique,Supply portMore than 3 '
The grain is caught in the rectangular opening 1 'of the hopper 1.
Sliding along the edge of the rectangular opening 1 '
Easily crushed grains.

Further, since the length of the short cylinder 7 is shorter than the length of the cylindrical space 4, the flow velocity of the air flow at one end increases along the spiral groove 6, so that residual grains can be eliminated.
