Description

[Detailed description of the invention]

[0001]

Industrial Applicability The present invention uses a single circulating grain dryer only by changing the number of rotations of a pay-out roll to an appropriate number of rotations. Damage soybeans that are liable to damage
The present invention relates to a circulating grain drying apparatus capable of drying without drying.

[0002]

2. Description of the Related Art Conventionally, a storage tank is provided in an upper stage, a ventilation drying cylinder is provided in a middle stage, and an extraction tank is sequentially provided in a three-dimensional manner in a lower stage. The feed roll is rotatably mounted on the shaft, and the storage tank and the take-out tank are connected via a circulation elevator, and the grains such as paddy, wheat, and soybeans dried in the ventilation drying unit are rotated by the rotation of the feed roll. A circulating grain drying apparatus that sequentially dries out into a take-out tank and then circulates and flows to a storage tank by a circulating elevator to dry it is described in, for example, Japanese Patent Publication No. 48-367.
No. 53 is publicly known.

[0003]

By the way, in this kind of conventional circulating grain drying apparatus, the number of rotations of the feeding roll is set on the basis of the time of drying grains such as paddy and wheat. The rotation speed is fast, for example, 48 to 53
r. p. m.

[0004] By the way, soybeans harvested by a harvester such as a combine are soft and easily damaged, so that when a soybean is dried using a device for drying cereals such as paddy and wheat, the number of rotations of a feeding roll is large. circulation rate becomes fast by, resulting lacerations grains or crushed grains often occur, has a problem that Ru <br/> be reduced commercial value.

[0005] Therefore, in the case of soybean drying,
The rotation speed of the soybeans
Slow the feed rate down to a speed that does not produce tears or crushed grains.
Although it seems to be possible, soybeans have a large particle size and
Because of the shape, simply reduce the number of rotations of the feeding roll.
Even if it does, the feeding amount does not decrease so much and the circulation speed
It turned out not to be late. On the other hand,
If the number of turns is reduced to an appropriate soybean feed amount,
Soybeans are firmly clogged in the feeding section and fed out
Not only does it hinder roll rotation,
When you rotate the soybeans soybeans
Was also found to cause damage.

The present invention has been made in view of the above-mentioned problems of the prior art. The purpose of the present invention is to use a feeding roll for drying rice, wheat or the like when drying.
~ 53r. p. m and fast rotated forward, also, rice is the likely time of soy drying wounded, about half of the time of wheat drying, i.e. 22-2
7r. p. In m, moreover the Rukoto is reversely rotated, soybean
When drying the rolls, make sure that the feeding roll does not hinder its rotation.
Even at relatively high rotational speeds, it is possible to
Sufficiently slow due to scraping action with feed-out regulation
It can be fed at a high speed, so that even with a single circulating grain dryer, not only paddy and wheat but also soybeans can be efficiently dried without generating cracks or crushed grains. It is an object of the present invention to provide a circulating grain drying apparatus which can be used.

[0007]

In order to achieve the above object, the circulation type grain drying apparatus according to the present invention has a storage tank in an upper stage, a ventilation drying cylinder in a middle stage, and an extraction tank in a lower stage. A feed roll is rotatably mounted in a feed section provided between the ventilation drying drum and the take-out tank, and the storage tank and the take-out tank are connected via a circulating elevator. Roll the paddy and wheat when drying
Rotation speed 48-53r. p. Dry by rotating forward at m
To paddy, to circulating fluidized wheat at a fast rate and the feed-out
When the soybean roll is dried with soybeans, the rotation speed is 22 to 27 r. p. m
Reverse rotation of the feeding roll to reverse
Slows drying of soybeans by regulated scraping action
It is designed to circulate at a high speed .

[0008]

[Effect] A case where rice and wheat are dried will be described.
Now, a predetermined amount of paddy or wheat is charged through a circulation elevator to a storage tank, a ventilation drying cylinder, and a feeding portion. Then, hot-air generator, one geared motor the rotational speed 48~53r with starting the suction exhaust fan. p. allowed forward rotation by m, Repetitive
The delivery roll is rotated at 48 to 53 r. p. Rotate forward with m
Ru eye.

[0009] In this case, the dried hot air that has been blown is immersed in the vertically drying grains in the ventilation drying cylinder in accordance with the rotation of the payout roll to dry the grains, and then dropped into the take-out tank. After that, a circulation operation is performed in which the water is returned to the storage tank via the circulation elevator. Therefore, the paddy and wheat stuffed in the dryer main body are dried to a predetermined finish moisture while being circulated at a high speed.

Next, when soybeans are dried by using the above-mentioned circulating grain drying apparatus, first, soybeans are filled in a predetermined amount in a storage tank, a ventilation drying cylinder and a feeding section by a circulation elevator, and then hot air is generated. Start the air blower and suction fan. Next, the geared motor is rotated at a rotational speed of 22 to 27 r. p. m and rotate the feeding roll at a rotation speed of 22 to 27 r. p. rotate in reverse so as to reach m.

Then, from the feeding section, the feeding roll
By the scraping action with the feed-out regulation by reverse rotation
Even though soybeans can be fed out at a sufficiently slow speed and are soft and easily scratched, the dry hot air that flows slowly and vertically through the inside of the ventilation drying cylinder from the storage tank according to the feeding operation by the rotation of the feeding rolls , And can be dried efficiently without generating tears or crushed particles.

Body. The main body 1 of the dryer is provided with a storage tank 2 having a sufficient amount of grain, for example, paddy, wheat, and soybeans, which have been exposed to dry hot air on the upper stage, and which has sufficient time for the grain itself to perform a refining action.
A draft drying drum 3 for drying the grains dropped by gravity from the storage tank 2 in the middle by drying hot air, and a substantially closed take-out tank 4 for collecting the grains subjected to the drying action by the drying hot air in the lower row. in which successively formed by sterically heavy set. Dryer book
The body 1 is formed in a horizontally long rectangular cylindrical shape or any other cross-sectional shape.

Inside the ventilation drying cylinder 3 whose periphery is covered with a non-perforated plate, one side is provided with a hot air generator 7 mounted on the front of the dryer body 1.
The hot-air fuze frames 5 and the lower portion of the hot-air exhaust frame 6 are alternately arranged vertically so that a relatively narrow drying passage 8 is formed between the frames 5 and 6. A delivery roll 10 is provided between the ventilation drying drum 3 and the removal tank 4, that is, in a delivery portion 9 disposed below the drying passage 8.
Are mounted so that they can be rotated quickly by the forward rotation of one geared motor 15 or relatively slowly by the reverse rotation .

The above-mentioned feeding roll 10 is made of hard-to-scratch paddy,
One geared motor 15 is used for drying grain such as wheat.
48-53r. p. m, the paddy and wheat are efficiently dried while circulating and flowing at a high speed, and the geared motor 15 is operated in reverse rotation for 22 to 27 r. p. The soybeans are rotated in the reverse direction at the number of rotations of m and fed out by the feed roll 10.
Repetition at a sufficiently low speed
The dried soybeans having high commercial value can be obtained without causing tears or crushed grains while circulating at a slow speed.

A suction air blower 11 having a suitable suction force is disposed on one side of the take-out tank 4, and a circulation side having a discharge side standing on one side of the dryer body 1 is provided at the bottom of the take-out tank 4. A discharge gutter 13 connected to a lower portion of the elevator 12 is provided horizontally. Reference numeral 14 denotes a carry-in gutter laterally provided on the top of the dryer main body 1, and its supply side is connected to an upper part of the circulating elevator 12.
