Description

  The present invention relates to a grain drying device that includes a shunt moisture meter and uniformly heats the grain.

The conventional wet grain drying method is to dry the wet grain in the grain drying facility. FIG. 1 shows a cross-sectional view of a conventional grain drying facility.
This grain drying facility includes a drying chamber 90, a grain scattering mechanism 98 is installed above the drying chamber 90, and wet grains are dropped from the grain scattering mechanism 98 above the drying chamber 90. A mechanism (not shown) such as a hot air outlet is installed in the drying chamber 90 and blows hot air to dry the wet grain. However, since the conventional drying chamber 90 has only one hot air outlet and blows hot air in a single direction, the wet kernel receives heat only on one side, and the wet kernel One side was excessively dried and burnt, the other side was not completely dried, and there was a defect that grain dry quality was poor, and the selling price could not be raised.

  A moisture meter is usually used to measure the degree of grain drying. Currently, an on-line moisture meter 95 is commonly used as a moisture meter. In general, the moisture meter 95 is installed on the side wall of the drying chamber 90, and when the grain passes through the moisture meter 95 and contacts the measurement surface 96, the moisture meter 95 measures the moisture content of the grain. However, the on-line moisture meter cannot obtain accurate data unless measuring environmental factors such as density, uniform distribution, flow rate, and contamination by foreign substances. If the environmental element where the moisture meter is placed is unstable, accurate moisture content data cannot be obtained.

Further, the conventional method of installing the moisture meter 95 on the side wall of the drying chamber 90 is that the space inside the drying chamber 90 is quite large, so that the grains easily generate random movement without discipline in this large space. Since the change in environmental factors becomes large, the moisture meter is susceptible to interference, often resulting in deviations in the measured data. However, at this time, it is easy for a contractor to misunderstand that the moisture meter is faulty, and he tries to solve it by replacing the moisture meter. However, after a while after the exchange, there is a situation in which deviation occurs in the measured data again, which is the biggest problem in the industry.
In addition, the grain is dropped downward from the grain scattering mechanism 98 above the drying chamber 90, and a large amount of grain constantly hits the measurement surface 96 of the moisture meter 95, so that the measurement surface 96 is eroded and damaged. This leads to a phenomenon that the measurement data becomes inaccurate. For this reason, when a moisture meter is installed as in the prior art, a situation often occurs in which the moisture meter must be replaced many times or a repair of the moisture meter must be requested.

Furthermore, in the conventional rice drying method, foreign matters such as dead branches and dead leaves are introduced from the upper part of the drying chamber 90 together with wet grains, and foreign matters such as chaff, dead branches and dead leaves are also added to the dried grains. In order to mix, it is necessary to screen and separate with another facility.
For this reason, performing operations such as drying, sieving / separating, etc., not only wastes equipment costs, but also has poor operating efficiency. In particular, foreign matters such as rice husks are very susceptible to the phenomenon of covering the grain and are difficult to separate from the grain. Traders often spend large amounts of equipment and struggle to overcome this covering phenomenon.

  The problem to be solved by the present invention is to solve the above-mentioned problems, to uniformly dry the grain, to measure accurate data with the moisture meter, to prevent the moisture meter from being worn, and to prevent the grain and foreign matter after drying. It is an object of the present invention to provide a grain drying apparatus that has high separation efficiency and can easily collect concentrated foreign substances after drying.

  The grain drying apparatus of the present invention includes a drying unit, a shunt moisture measurement unit, a foreign matter separation unit, and a foreign matter collection unit, and the drying unit includes a drying chamber therein, and the drying chamber has a plurality of stages of grain drying. A mechanism is installed, and a hot air outlet is provided in each of the plurality of stages of grain drying mechanisms to form a plurality of stages of hot air outlets, and the plurality of stages of hot air outlets are provided at the center and both sides of the grain drying mechanism. The hot air outlets at each stage blow hot air in opposite directions to each other, and two openings are opened in the drying unit, and the shunt moisture is formed outside the drying unit between the two openings. An amount measuring unit is installed, the shunt moisture measuring unit includes an intake pipe, a measurement pipe, a delivery pipe, and a moisture meter, and one end of the intake pipe and the delivery pipe is two openings of the drying unit And both ends of the measurement pipeline are connected to the intake pipeline and The moisture meter is connected to the other end of the delivery line, the moisture meter is installed in the measurement line, and the foreign matter separating unit is formed by installing a separation drum at the bottom of the drying unit. A collection port is provided, a grain discharge port is provided below the separation drum, and the grain and foreign matter are separated by a thin layer separation effect formed by rotation of the separation drum; The collection unit is installed at a downstream location of the foreign substance separation unit, and includes a foreign substance collection cylinder, a foreign substance introduction pipe, an exhaust pipe, an exhaust fan, and a baffle, and the foreign substance introduction pipe is installed on one side of the foreign substance collection cylinder, The exhaust pipe and the exhaust fan are installed on the upper surface of the foreign material collecting cylinder, the baffle is installed inside the foreign material collecting cylinder, and separated by a thin layer effect at the lowermost end of the foreign material collecting cylinder. A small amount sampled by the shunt water content measurement unit through which an opening used for collecting foreign matter is formed, and the grain is introduced from the upper end of the drying unit, and undergoes multistage alternating drying with respect to the grain of the drying unit. The moisture content is measured with respect to the grain, and the dried grain and foreign matter are separated by the thin layer effect by the foreign matter separating unit, and the foreign matter is settled and collected by the foreign matter collecting unit.

The direction of the hot air blown out from the odd-numbered hot air outlets may be opposite to the direction of the hot air blown out from the even-numbered hot air outlets.
In this case, the hot air blown out from the odd-stage hot air outlets may be blown out from the center toward both sides, and the hot air blown out from the even-stage hot air outlets may be blown out from both sides toward the center.
The separation drum rotates, and heavy grains are dropped to the lower layer and light foreign matters are lifted to the upper layer by the action of the rotational centrifugal force of the separation drum.
The foreign material introduction tube of the foreign material collection unit may be connected to a foreign material discharge location formed at the end of the foreign material collection port of the foreign material separation unit and locked and fixed by a fixing device.
The baffle prevents the foreign matter from moving forward, and drops the foreign matter to the opening.

It is desirable to provide a grain transport mechanism and a grain lifting mechanism for transporting the grain discharged from the grain outlet to the upper part of the drying unit and dropping the grain downward from above the drying chamber again.
A rotating roller which is a delivery mechanism for sending a part of the grains in the drying chamber to the drying chamber through the shunt moisture amount measurement unit is installed in the internal passage of the continuous contact point between the measurement pipeline and the delivery pipeline. Also good.
Alternatively, a first gate is installed in the internal passage of the communication contact between the intake pipe and the measurement pipe, and a second gate is installed in the internal passage of the communication contact between the measurement pipe and the delivery pipe.

You may install the rotation roller which is a delivery mechanism which sends a part of grain of this to the said drying chamber through the said shunt moisture content measurement part.
A glass material may be used for the measurement surface of the moisture meter.

In the present invention, by alternately drying in multiple stages, each surface of the wet kernel can be heated on average to be completely dried, and the wet kernel is heated only on one side and not completely dried. Or the problem of excessive drying on one side and scorching.
In addition, since the moisture meter is installed outside the drying unit in a shunt system, measurement can be performed while avoiding interference with environmental elements, and at the same time, the service life of the moisture meter can be extended and a large amount of grains passing through the drying chamber can be obtained. Since it does not hit the moisture meter, the service life can be extended by slowing the rate of wear of the moisture meter.
Furthermore, due to the thin layer separation effect of the separation drum, the grain and foreign matter after drying are quickly separated, and the foreign matter generated after drying is easily and intensively collected by allowing the foreign matter to settle and collect. And environmental pollution can be avoided.
In addition, the efficiency of the apparatus is increased by continuously performing a series of operations such as uniform drying of the grain, moisture measurement in the shunt, rapid separation of the grain and foreign matter, and concentrated collection of foreign matter.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 to 5 show a first embodiment of the present invention.
FIG. 2 is a cross-sectional view of the grain drying apparatus according to the first embodiment. The grain drying apparatus includes a drying unit 10, a shunt moisture measurement unit 20, a foreign matter separation unit 30, a foreign matter collection unit 40, and the like.
The drying unit 10 is provided with a drying chamber 14 that receives the wet kernel and has a mechanism for drying the wet kernel. The drying chamber 14 is provided with a plurality of stages of grain drying mechanisms. In the first embodiment, the first stage grain drying mechanism 11, the second stage grain drying mechanism 12, and the third stage are provided. It has an eye grain drying mechanism 13. Of course, the number of stages of the grain drying mechanism is not limited to this.

  The first stage grain drying mechanism 11, the second stage grain drying mechanism 12, and the third stage grain drying mechanism 13 are provided with hot air outlets 15, 16, and 17, respectively. For example, the first stage air drying mechanism 11 that is an odd-numbered stage is provided with a first hot air outlet 15 at the center, and the second stage grain drying mechanism 12 that is an even number is provided with a second hot air outlet 16 on both sides. And the 3rd stage grain drying mechanism 13 which is an odd number stage is provided with a third hot air outlet 17 in the center. The 1st hot-air blower outlet 15, the 2nd hot-air blower outlet 16, and the 3rd hot-air blower outlet 17 blow off the hot air supplied from the hot air source (not shown), and dry the wet grain which passes.

  The direction of the hot air blown out from the first hot air outlet 15 is opposite to the direction of the hot air blown out from the second hot air outlet 16, and the direction of the hot air blown out from the second hot air outlet 16 is the third direction. The hot air outlets 17 are alternately arranged in opposite directions. For example, the hot air blown from the first hot air outlet 15 is blown out from the center toward both sides, the hot air blown out from the second hot air outlet 16 is blown out from both sides toward the center, and the third hot air blower outlet 17 is drawn from the center to both sides. It is blown out toward For this reason, when the passing wet grain passes through the first stage grain drying mechanism 11, the first hot air outlet 15 blows hot air to dry one side of the wet grain. When the wet grain passes through the second stage grain drying mechanism 12, the hot air blown out by the second hot air outlet 16 performs heat drying on the other side of the wet grain. When the wet grain passes through the third stage grain drying mechanism 13, the hot air blown out by the third hot air outlet 17 again dries the original side of the wet grain.

  In this manner, the drying is alternately and repeatedly performed, and both sides are repeatedly and uniformly heated like Sate (Sate BBQ), and only one side is excessively heated, and the phenomenon of scorching hardly occurs. For this reason, it is possible to dry completely by repeatedly drying in multiple stages and applying heat to each side of the wet kernel on average, and one side of the conventional wet kernel is heated. In the drying method, the wet grain cannot be completely dried, or only one side is excessively dried and burnt, thereby improving the disadvantage that the quality is deteriorated. Furthermore, the grain drying mechanisms 11, 12, and 13 can simultaneously form one traveling flow line, guide the wet grain and sequentially advance it, and dry it.

Two openings, that is, a first opening 18 and a second opening 19 are opened in a predetermined place of the drying unit 10, and a shunt is made to a predetermined place between the first opening 18 and the second opening 19 outside the drying unit 10. A moisture measuring unit 20 is installed.
The shunt moisture amount measurement unit 20 includes an intake pipe 21, a measurement pipe 22, a delivery pipe 23, a delivery mechanism 24, a moisture meter 25, and the like.
One end of the intake pipe 21 is connected to the first opening 18 of the drying chamber 14, and the other end is connected to the measurement pipe 22. One end of the delivery line 23 is connected to the second opening 19 of the drying chamber 14, and the other end is connected to the measurement line 22. For this reason, the sampling grain 50 in the drying chamber 14 can be caused to enter the shunt moisture amount measuring unit 20 from the first opening 18 and returned to the drying chamber 14 from the second opening 19.
The delivery mechanism 24 is installed at a predetermined location in the internal passage of the contact point between the measurement pipeline 22 and the delivery pipeline 23. The delivery mechanism 24 can be a delivery roller, is driven by a motor (not shown), and the sampled grain 50 after being measured by the moisture meter 25 is fed by the rotating roller of the delivery mechanism 24, and the grain 50 Is returned to the drying chamber 14 via the delivery line 23 and the second opening 19.

The moisture meter 25 is installed at a predetermined location of the measurement line 22, and the sampling grain 50 that has entered from the first opening 18 and the intake line 21 can be brought into contact with the moisture meter 25. After that, the moisture content information of the grain 50 is output, and the grain 50 that has been measured is sent again to the rotating roller of the sending mechanism 24 and returned to the drying chamber 14.
For this reason, since only a very small amount of the sampling grain 50 is taken out and brought into contact with the moisture meter 25 by the shunt moisture amount measuring unit 20, it is possible to suppress environmental interference elements and stabilize the measurement environmental elements. Therefore, accurate use and measurement can be performed with the moisture meter 25, and accurate moisture content data of the grain 50 can be obtained. At the same time, since only a small amount of the sampling grain 50 is allowed to pass through the shunt moisture measurement unit 20, the high density grain 50 constantly impacts the measurement surface 26 of the moisture meter 25, and the moisture meter 25 is quickly worn out. The situation can be avoided and the service life of the moisture meter 25 can be extended. In addition, in order to increase the degree of wear resistance of the moisture meter 25 measurement surface 26, a glass material is used for the moisture meter 25 measurement surface 26, and the lifetime of the moisture meter 25 can be extended by utilizing the abrasion resistance of glass. it can.

As shown in FIGS. 2 and 3, the foreign matter separation unit 30 is configured by a separation drum 32 installed at the bottom of the drying unit 10. During operation, the separation drum 32 is rotated in the clockwise direction. Therefore, when the dried grain 50 and the foreign matter 55 fall on the separation drum 32, the relatively heavy grain 50 is caused by the action of the rotational centrifugal force of the separation drum 32. Falls to the lower layer, and relatively light foreign matter 55 such as rice husk, rice grass, dead branches and dead leaves rises to the upper layer (as indicated by arrows in FIG. 3).
A foreign matter collection port 34 is provided at a predetermined location near the separation drum 32, the floating foreign matter 55 is discharged from the foreign matter collection port 34, and the foreign matter 55 discharged by the collecting device is collected in a concentrated manner.

  A grain outlet 36 is provided at a predetermined location near the separation drum 32, and the grain 50 is discharged from the grain outlet 36, and is installed beside the grain transport mechanism 62 and the drying unit 10. It is conveyed to the upper part of the drying unit 10 by the grain lifting mechanism 64, sent again from the transport pipe 66 to the grain scattering mechanism 68, and the grain 50 is dropped downward from above the drying chamber 14, and the grain 50 After the drying operation is repeated until the water reaches a predetermined level, the grain 50 is taken out. It is necessary to borrow the power of the moisture meter to determine whether the grain 50 has reached a predetermined degree of drying.

  In the present invention, a thin layer effect is formed by the rotation of the separation drum 32, and the dried grain 50 and foreign matter 55 such as chaff, dead branches and dead leaves can be easily separated. In particular, rice husk is likely to cover the grain 50 after drying and is difficult to separate, but this problem can be easily solved by the thin layer effect formed by the rotation of the separation drum 32. There is no doubt that conventional grain drying methods are a major advance compared to the disadvantage of not being able to reduce the covering of rice husks, even at the expense of huge equipment costs.

As shown in FIGS. 2 and 4, the foreign material collecting unit 40 is installed downstream of the foreign material separating unit 30 and includes a foreign material collecting cylinder 42. A foreign material introduction tube 44 is installed on one side of the foreign material collection tube 42, an exhaust tube 46 is installed on the upper surface of the foreign material collection tube 42, an exhaust fan 49 is installed, and a baffle 48 is installed inside the foreign material collection tube 42. Is done. Below the foreign material collection cylinder 42 is formed in a gradually narrowed shape, and an opening 45 used for collecting the foreign material 55 separated by the thin layer effect is formed at the lowermost end thereof, whereby the foreign material collection unit 40 is configured. The
The foreign material introduction tube 44 of the foreign material collection unit 40 is connected to a foreign material discharge location formed at the end of the foreign material collection port 34 of the foreign material separation unit 30 and is locked and fixed by a fixing device.

  Due to the thin layer action generated by the rotational centrifugal force of the separation drum 32, the relatively heavy grain 50 dropped to the lower layer is discharged from the grain discharge port 36, and the foreign matter 55 such as rice husk that is lifted and separated because it is relatively light. Enter the foreign material collection port 34. Subsequently, the foreign matter 55 advances further under the influence of the suction force of the exhaust fan 49, and when it hits the baffle 48, it falls along the baffle 48 to the opening 45, and the user evades the rice husk discharged at the 45 locations of the opening. Or the like. The baffle 48 has a predetermined length, and a predetermined gap is formed between the bottom of the baffle 48 and the bottom of the foreign material collecting cylinder 42 to serve as an air flow path when the exhaust fan 49 is sucked. For this reason, even if the foreign object 55 hits the baffle 48 and cannot move forward, the air continues to advance from the gap and is exhausted from the exhaust fans 49 at the 46 exhaust pipes. That is, the foreign matter 55 is collected by collecting the foreign matter 55 in a concentrated manner so that the foreign matter 55 is not scattered around and the operating environment can be kept clean.

FIG. 5 is a cross-sectional view of the grain drying apparatus during operation.
The wet grain 50 is introduced from the upper end of the drying unit 10, advances through the guides of the first stage grain drying mechanism 11, the second stage grain drying mechanism 12, the third stage grain drying mechanism 13, and the first stage The 1 hot air outlet 15, the second hot air outlet 16, and the third hot air outlet 17 blow hot air in opposite directions (indicated by arrows in the figure), and perform alternate drying of the grains 50 in a multistage manner. Each surface of the grain 50 is repeatedly heated on an average to dry the grain 50 completely.
Subsequently, the dried grain 50 proceeds to the foreign matter separation unit 30, receives the action of the rotational centrifugal force of the separation drum 32, the relatively heavy grain 50 falls to the lower layer, and the relatively light foreign matter 55 becomes the upper layer. The foreign matter is separated by the thin layer effect, and the grain 50 and the foreign matter 55 are separated.

The separated foreign matter 55 receives the action of the suction force of the exhaust fan 49 and proceeds forward. When the foreign matter 55 hits the baffle 48, it falls to the opening 45 along the baffle 48, and the sediment collection effect of the foreign matter is achieved. The user can collect the foreign matter 55 discharged at the 45 positions of the opening and keep the operating environment clean and clean.
The grain 50 that has fallen to the lower layer is discharged from the grain discharge port 36, carried to the upper part of the drying unit 10 by the grain transport mechanism 62 and the grain lifting mechanism 64, and again from the transport pipe 66 to the grain scattering mechanism 68. And the grain 50 is dropped down above the drying chamber 14.

The dropped grain 50 is sampled from the first opening 18 and enters the shunt moisture measurement unit 20, and after contact / measurement with the moisture meter 25, the moisture content information of the grain 50 is output. The sampled grain 50 is returned to the drying chamber 14 from the second opening 19 again, and the above-described multistage alternating drying is performed.
The moisture content information of the grain 50 measured by the moisture meter 25 is a basis for determining whether or not the grain has reached a predetermined degree of drying. For this reason, until the grain 50 is dried to a predetermined level, it is possible to take out the grain that has been dried, after repeatedly performing multi-stage alternating drying cyclically.

  Since the shunt moisture measurement unit 20 only takes out a small amount of the grain 50, it can suppress the environmental interference elements and stably maintain the measurement environmental elements, whereby the shunt moisture measurement unit Accurate measurement and use can be performed with the moisture meter 25 installed on the top 20, and accurate moisture content data of the grain 50 can be obtained. At the same time, since only a small amount of the sampling grain 50 is allowed to pass through the shunt moisture measurement unit 20, the high density grain 50 constantly impacts the measurement surface 26 of the moisture meter 25, and the moisture meter 25 is quickly worn out. The situation can be avoided and the service life of the moisture meter 25 can be extended.

FIG. 6 shows a second embodiment of the present invention.
The shunt moisture amount measurement unit 20 is installed outside the drying unit 10, and includes an intake pipe 21, a measurement pipe 22, a delivery pipe 23, a first gate 72, a second gate 74, a moisture meter 25, and the like. Composed.
Example 1 and Example 2 have substantially the same structure, but the most important difference is as follows.

Or it can be blocked. The second gate 74 is driven by the second hydraulic cylinder 75.
When the first hydraulic cylinder 73 is activated and the first gate 72 is opened, the intake pipe 21 and the measurement pipe 22 are communicated, and the sampling grain 50 in the drying chamber 14 enters from the first opening 18. After the measurement with the moisture meter 25, the grain 50 falls onto the second gate 74. At this time, when the second hydraulic cylinder 75 is operated and the second gate 74 is opened, the measurement pipeline 22 and the delivery pipeline 23 are communicated, and the sampling grain 50 passes through the delivery pipeline 23 and the second opening 19. Returned to the drying chamber 14.
