Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is applicable to communal paddy drying and preparation facilities (rice centers, etc.)
The rice husks produced in the rice husks are compressed and ground under high heat to break down the strong bonds of the rice husks' fibers and solidify them, making them easier to collect and transport. The rice husk crusher is used to process pickled rice husks for various uses such as food and feed, and in particular, in the process before the rice husk crusher, the raw rice husk is crushed to a certain moisture content (moisture content). This invention relates to a raw material rice husk drying device for a rice husk crusher that dries rice husks.

[Prior art] This type of rice husk crusher is disclosed in, for example, Japanese Patent Application Laid-Open No. 52-9

sticky state) is also classified. The raw rice husks from which foreign matters have been removed are guided to the supply hopper of the rice husk drying device 45 and fed into the stirring cylinder 50 by the rotary valve 49. The rice husks in the rotating stirring cylinder 50 are gradually moved toward the discharge pipe 56 while being stirred by the stirring projections 50b, and are subjected to a drying effect by the hot air blown from the hot air generator 46. The hot air is supplied through a rotary valve 49.
．． 57 so that it does not escape from the supply hopper 48 or the discharge pipe 56, and after sufficiently drying the raw material rice husk, it is discharged from the exhaust port 55 to the outside of the machine. The rice husks that have been dried in this way flow into the duct 58 through the discharge pipe 756, and are air conveyed by the feeder J [59] to reach the cyclone 60. It should be noted that drying of the rice husks continues while the rice husks are being air conveyed through the duct 57.

Air and rice husks are separated in the cyclone 60, and the rice husks are transferred to a rice husk tank 6 for drying by a screw conveyor 62.
1. The dried rice husks in the rice husks tank 61 are conveyed to the supply tube 2 of the rice husk crusher 1 by a screw conveyor 63.

The operation of the rice husk crusher 1 will be described below.

Start the motor of the fan that communicates with the machine motor 10 and the porous wall 40, and
When the shutter 4 is opened by operating the shutter 4, the rice husks flow down from the supply port 3 to the funnel stand 6.

The rice husks in the sixth funnel are sent into the chrysanthemum sleeve 16 and toward the compression sleeve 18 by a large-diameter screw blade 15A provided on the screw 14 that rotates together with the shaft 7.

At this time, the rice husk is inserted into the relay screw blade 15B (screw blade 15
Conveying force is smaller than A. ) and is compressed (the screw blade 15A also acts as a lid to prevent the rice husks from flowing back), and coarse crushing is performed.

The grooves on the inner circumferential surface of the chrysanthemum sleeve 16 act as resistance to the flow of rice husks and promote crushing of the rice husks. Next, the rice husks transferred into the compression sleeve 18 whose cross-sectional area gradually decreases are further compressed and crushed by the screw blade 15G. In the case of a polygonal shape (rounded corner shape), internal resistance within the compression sleeve 18 increases, and the action of crushing the rice husks against each other becomes active.

In this way, the rice husks are compressed and crushed into powder, and the compression sleeve 18 is heated by the heater 21 (approximately
This heat breaks down the strong bonds of the fibrous tissue (cellulose, etc.) in the rice husk, making it soft enough to be used as feed, etc.

Powdered rice husk, whose apparent specific gravity is more than 10 times that of the raw material, is further sent to the vicinity of the tip of the screw 14, where the forwarding force is further reduced, and in addition, friction with the compression sleeve 18 and the forming sleeve 19 increases. As the coefficient becomes larger,
It is sequentially solidified at the end of the compressed sleeve 718 and within the molded sleeve 19. This solidified rice husk is sent out to the discharge port 20 side by the end of the screw blade 15C, and is pushed out of the machine from the discharge port 20 as a crushed object.

To some extent (30 to 50 mm) from the discharge port 20
When the cutter device 28 is started at the time of being pushed out,
The crank arm 31 is rotated by the rotation of the geared motor 30.
causes the connecting rod 32 to move up and down, so that the lower end of the cutter 29 hits the drawn object, and this shock causes the drawn object to be cut and fall into the discharge gutter 33. The crushed objects flow down from the discharge gutter 33 to the guide gutter 34 and are discharged from the discharge port 35 to the outside of the machine, but while passing through the guide 134, small pieces attached to the drawn objects fall into the plan case 36. do.

As mentioned above, the regular operation of the rice husk crusher continues, but if the operation is interrupted due to poor molding of the wetted material due to wear of the screw 14 or instability of the temperature of the heater 26, etc. Operate the oil cylinder 27 to expose the screw 14, or remove the bolts and nuts sewn onto the upper part of the cylinder 17 to open the cylinder 17, compression sleeve 18, and molding sleeve 19 to repair or replace the molding. The wet pickles remaining in the sleeve 18 that are in the process of being molded are taken out and the operation is restarted.

Figure 5 shows hot air (60 to 80°C) discharged from the exhaust port 38.
This is an example of a rice husk drying device using the following. 64
is a drying tank in which rice husks to be dried are placed, and the lower end of the drying tank 64 is connected to the supply port 3 via the supply cylinder 2. 65 is a chute pipe for staking, 66 is a rotary valve provided on the chute pipe 65, 67 is a rice husk supply port, 68 is an exhaust part provided with a large number of holes to prevent rice husks from leaking out; Installed on the upper wall of the drying tank. Further, the exhaust section 68 may be provided with an exhaust fan 69.

The hot air discharged from the air supply hole 7 at the bottom of the drying tank 64
A blower 74 is a duct that connects the blower 72 and the air supply hole 73.

The operation of this embodiment will be described below. The rice husks introduced from the supply port 67 are dried by hot air sent from the air supply port while being agitated by the spiral blades 70. After drying, the hot air is removed from the machine through the exhaust section 68. Since the rotary valve 66 is provided, hot air will not escape into the chute vibe 65. In this case, the hot air generated by the rice husk crusher 1 is used as it is, so no fuel is required.Furthermore, when the rice husk drying device 45 is provided above the supply cylinder 2, the flow path is extremely short. This eliminates the need for conveyor equipment or long ducts.

〔Effect of the invention〕

As explained above, according to the present invention, a rice husk drying device for drying raw material rice husks is provided in the front stage of the rice husk crushing machine, and the discharge part of the rice husk drying device and the supply port of the rice husk crushing machine are connected to each other. Since the rice husks are connected through a channel, the raw rice husks supplied to the rice husk crusher are dried by the rice husk drying device to produce a constant low-moisture raw material $31
Therefore, in the rice husk crusher, accidents such as poor molding of crushed products due to uneven moisture content of the raw material are eliminated. In addition, since the raw material has low moisture content, there is less trapped water vapor generated during compression, crushing, and molding, which reduces the amount that adheres to the inside of the machine, the raw material, and the wall inside the main body, and the flow of the raw rice husk becomes smoother. .
