Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention enables one machine to circulate by simply changing the rotation speed of the feed roll to an appropriate rotation speed. Using a circular grain dryer, we remove damaged grains such as paddy and wheat as well as lacerated grains and crushed grains. Circulating grain drying that can efficiently dry even soybeans that tend to form grains. Regarding equipment.

0002

[Conventional technology]

Conventionally, the storage tank was placed in the upper tier, the ventilation drying cylinder was placed in the middle tier, and the take-out tank was placed in the lower tier. A feeding roll is installed in the feeding section provided between the ventilation drying cylinder and the taking-out tank. The storage tank and take-out tank are connected via a circulation elevator. The grains such as paddy, wheat, soybeans, etc. are dried in a ventilation drying section. After being fed into the take-out tank by the rotating operation of the pump, it is circulated to the storage tank by a circulation elevator. A circulating grain drying device capable of drying while causing fluidization was developed before this application, for example. It is described in Japanese Patent Publication No. 48-36753 and is well known.

0003

[Problem that the idea aims to solve]

By the way, in conventional circulation type grain drying equipment of this kind, the rotation of the feed roll is The rotation speed was set based on the time of drying grains such as paddy and wheat, so The number is fast, for example 48-53r. p. It was m. By the way, soybeans harvested with harvesters such as combines are soft and easily damaged. When drying soybeans using a device that dries grains such as paddy or wheat, The high rotational speed of the roller increases the circulation speed, resulting in a large number of ruptured and broken grains. This has caused a problem in that the product value is lowered.

0004 The present invention was made in view of these problems of the conventional technology. The purpose of this is to control the rotation speed of the feed roll when drying paddy, wheat, etc. 48-53r. p. When drying soybeans, which are easily damaged, it is possible to Approximately half of the drying time of wheat, that is, 22 to 27 r. p. Dry while rotating slowly. Therefore, even a single circulating grain dryer can handle not only paddy and wheat, but also soybeans. Circulating grain that can be efficiently dried without creating cracked or crushed grains The purpose is to provide a drying device.

[0005]

[Means to solve the problem]

In order to achieve the above purpose, the circulating grain drying device of the present invention has an upper storage area. A storage tank, a ventilation drying cylinder in the middle stage, and a take-out tank in the lower stage are installed three-dimensionally in order, and the ventilation The feeding roll is rotatably mounted on a shaft in the feeding section provided between the drying cylinder and the take-out tank. In addition, in the case where the storage tank and the extraction tank are connected via a circulation elevator, When drying paddy and wheat, one geared motor rotates in the forward direction. 48-53r. p. m, and the geared motor is reversed when drying soybeans. 22~27r by rotating. p. m.

[0006]

[Effect]

The case of drying paddy and wheat will be explained. Now, the paddy or wheat is passed through the circulation elevator to the storage tank, ventilation drying drum, and feeding section. Fill the specified amount. Next, the hot air generator and suction/exhaust fan are started, and one geared motor is 8-53r. p. Rotate m rotations. Then, the generated drying hot air flows inside the ventilation drying cylinder according to the rotation of the delivery roll. The grains are successively poured down the vertical stream to dry them, and then dropped into the take-out tank. After being introduced into the tank, the water is returned to the storage tank via a circulation elevator, creating a circulation effect. did Therefore, while the paddy and wheat placed inside the dryer are circulated at a relatively high speed, It is dried to a predetermined finish moisture level.

[0007] Next, if you want to dry soybeans using the circulating grain dryer, first A circulation elevator is used to fill the storage tank, ventilation drying cylinder, and feeding section with a predetermined amount of soybeans. After that, start the hot air generator and suction exhaust fan. Next, the geared motor is reversely rotated to rotate the delivery roll to 22 to 27 r. p. becomes m It rotates slowly. Even if the soybeans are soft and easily damaged, they can be ventilated slowly from the storage tank. The flow is carried out vertically in the drying cylinder in response to the feeding operation caused by the rotation of the feeding roll. Dry efficiently by blowing dry hot air that passes through the grains without causing cracked or crushed grains. be able to.

[0008]

【Example】

Examples will be described with reference to the drawings. In FIGS. 1 and 2, 1 indicates grains, such as paddy, which have been exposed to dry hot air in the upper row. When wheat and soybeans are allowed to stand for a period of time, the grains themselves have sufficient capacity to undergo tempering. The grains that have fallen by gravity from the storage tank 2 in the middle stage are dried by being exposed to dry hot air. There is a ventilation drying cylinder 3 for drying, and a lower stage for collecting grains that have been exposed to dry hot air and dried. The main body of the dryer is a three-dimensional stack of sealed take-out tanks 4, and the whole is horizontally long. It is formed into a rectangular tube shape or other arbitrary cross-sectional shape. Inside the ventilation drying cylinder 3 whose surroundings are covered with a blind plate, one side is equipped in front of the dryer main body 1. The hot air blower frame 5 and the lower part are connected to the heated hot air generator 7 and the lower part thereof is connected to the extraction tank 4. and a hot air exhaust frame 6 such that a relatively narrow drying passage 8 is formed between both frames 5 and 6. Alternately install them vertically. And, between the ventilation drying cylinder 3 and the take-out tank 4, that is, the drying passage In the feeding section 9 disposed at the bottom of the roller 8, feeding rolls 10 each have one geared motor. The shaft is mounted so that it can be rotated quickly or slowly by the forward and reverse rotation operation of the motor 15. ing. The above-mentioned feed roll 10 is used for drying grains such as paddy and wheat that are hard to damage. 48 to 53r. due to the forward rotation operation of the geared motor 15. p. rotates at a rotation speed of m This allows paddy and wheat to be efficiently dried while circulating and flowing at a high speed. During soybean drying work, the geared motor 15 rotates in reverse to rotate 22-27r. p. m's The soybeans are rotated at a high rotational speed, and the soybeans are circulated at a slow speed to remove cracked grains and fractures. Dried soybeans with high commercial value can be obtained without producing grains. A suction exhaust fan 11 having an appropriate suction force is disposed on one side of the take-out tank 4. At the same time, at the bottom of the take-out tank 4, there is a circulation lift installed on one side of the dryer main body 1 on the take-out side. A discharge gutter 13 connected to the lower part of the dismounter 12 is installed horizontally. 14 is the dryer body A carry-in gutter installed horizontally at the top of the circulation elevator 1, the supply side of which is connected to the upper part of the circulation elevator 12. It is continued.

[Effect of the idea]

Since the present invention is configured as described above, it produces the following effects. When drying paddy, wheat, etc. that are hard to damage, use a single gear motor to feed out the rolls. 48 to 53r by normal rotation of the motor. p. Rotate the grain as fast as m to make the grain more efficient. When drying easily damaged soybeans, the feed roll is rotated 22 to 27 times. r. p. Rotate slowly as shown in the figure below to prevent cracking or broken particles. Dried soybeans with high quality can be obtained efficiently. Therefore, in this invention, even if there is only one circulating grain dryer, the feeding roller Not only paddy and wheat but also soybeans can be easily dried by simply increasing or decreasing the rotation speed of the dryer. Can be dried.
