Description

[Detailed description of the invention] In this invention, the bottom of the grain storage base 1 and one side of the upper space 2 are communicated with each other by means of a grain lifting cylinder 3, and the other side of the upper space 2 is opposite to the upper communication part 5. An internal air exhaust blower 6 is installed in the
A passage 10 is formed near the suction side of the blower 6, and a bell mouth presser plate 7 is provided, and a grain distribution guide cage 8 is constructed between the bellmouth presser plate I and one side of the space 2. The present invention relates to a grain drying device.

The grain ascending conveyance cylinder 3 becomes a thrower by rotating the rotary blades 9 at high speed, and when rotating at low speed, it becomes a pneumatic transport cylinder by the blower 6. In the case of pneumatic transport, the grain is fed into the cylinder 3 at 8 m/sec. This generates the above upward air current.

The bell mouth presser plate I is provided vertically and its upper end is curved toward the grain ascending conveyance cylinder 3, but the present invention is not limited to this, and it may be inclined upward toward the cylinder 3.

A passage 10 is formed between the upper end of the bellmouth holding plate r and the upper surface of the root surface 1.

The grain distribution guiding cage 8 is made of wire having a triangular or small cross section and made of smooth metal, hard plastic, or wood strips arranged at equal intervals as shown in FIG.

In the figure, 11 indicates a generation chamber for hot air, etc., 12 indicates a ventilation drying chamber for hot air, etc., 13 indicates an outlet of the ventilation drying chamber 12, and 1
4 is a screw conveyor, 9 is the same screw conveyor 1
A rotary blade for raising grains provided at one end of 4 and at the bottom of the ascending conveyance tube 3; 15 for stored grains; 16 for grain diffusion guide plates; 17 for grain distribution; and 18 for other grains. 19 is a subroof, and 20 is a flow velocity promotion guide plate.

4, 5, and 6 show the grain diffusion guide plate 16 installed on the ceiling of the communication section 5. As shown in FIGS.

Therefore, first, when the rotary blade 9 is rotated and grains such as undried paddy are fed thereto, the grains are energized by the rotation and ascend the ascending conveyance cylinder 3, passing through the upper communication part 5 into the upper space of the root surface 1. When entering the space 2, it is guided by the diffusion guide plate 16, 16, expands in the width direction of the space 2, and enters the room 1 where hot air etc. are generated.
1 and is stored 15 in the ventilation drying chamber 12.

Then, dry air such as hot air is sent from the generation chamber 11 into the ventilation drying chamber 12, and by rotating the blower 6, the air is raised at a rate of 8 m/sec or more into the ascending conveyance tube 3, and the rotary valve The grains are discharged from the outlet 13 by the screw conveyor 14 and moved to the lower communication part 4 by the upward air current and ascend the ascending conveyance cylinder 3. The airflow toward the opposing blower 6 causes the particles to move over the grain distribution guide basket 8 while falling naturally due to their own weight and onto the stored grains 15 below by the baffle plate 17 and the bell mouth presser plate 18. Diffusion descent - stored grains 15
In addition to equalizing the upper surface, grain dust generated during circulation drying is floated in the same direction a by the air stagnant inside the bell mouth presser plate 7 7' and the airflow in the direction of arrow a, and
0 and then ejected from the machine.

Conventionally, the grains ascending through the grain ascending transport cylinder 3 enter the upper space 2 in a nozzle-like manner from the upper communication portion 5 and fall, so the upper surface of the stored grains 15 is inclined, making it difficult to descend the grains 15 evenly. The drying air that rises over the grains 15 is also uneven, resulting in uneven drying of the grains, which significantly reduces the quality of the grains, and also has the defect that dust cannot be discharged to the internal temperature.

Since the present invention is configured as described above, the communication portion 5 is provided in the upper space 2.
The grains entering from 75 move over the grain distribution guide basket 8, increasing the flight length of the grains and making it easier to spread them evenly.The upper surface of the stored grains 15 is leveled relatively horizontally, The plate R creates a stagnation area for the internal air to make the dust rise to the surface, and grains with their own weight are allowed to fall, so there is no chance that m of paddy etc. will be discharged by mistake, and only the dust is discharged to the internal temperature. It is possible.

Then, the stored grain 15 is lowered evenly and the same grain 1
The rising air can rise evenly through the inside of the dryer, which facilitates uniform circulation and uniform drying of the grains, which has the practical benefit of reducing deterioration in the quality of the dried grains.
