Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention effectively uses dehumidified air obtained by a dehumidifier to efficiently grow grain. This invention relates to a dehumidifying drying facility that can obtain dried grains with good taste by drying them.

0002

[Conventional technology]

Traditionally, multiple grain dryers were installed inside a drying facility to dry the grains brought in. The drying technique for drying is generally used and well known, needless to mention the precedent of this application. Ru. By the way, in the conventional drying technology of this type, the amount of grain that is brought into the facility per day is The amount of drying is not constant depending on the weather and other conditions, so even if there are many dryers, If the capacity is lower than the dryer's processing capacity, the number of dryers that can be used will inevitably be reduced. As a result, the drying capacity installed in the facility is not fully utilized, and expensive equipment is being used. The disadvantage is that a lot of idle time occurs.

0003 In addition, as a means of drying technology, the dry air intake part of the circulation dryer is Equipped with an integrated dehumidifier, the low-temperature, low-humidity dehumidified air obtained by the dehumidifier is sent to the dryer. Drying with good taste by dehumidifying and drying the grains that are supplied and circulated through moisture absorption. A dehumidifying dryer designed to obtain grains was also developed before this application, for example, in Japanese Patent Application Laid-Open No. 2-302576. It is known as described in the report.

[Problem that the idea aims to solve]

Therefore, we installed multiple previously known dehumidifying dryers of this type in the drying facility. We aim to improve the taste of the grains brought into the warehouse by effectively utilizing the moisture absorption effect of dehumidified air. However, even if you try to efficiently dehumidify and dry the grain, the amount of grain brought into the facility is affected by weather and other factors. There are variations in other conditions, for example, a dehumidifying dryer with a drying capacity of 20 tons is If 50 to 60 tons of grain is brought in, three dehumidifying and drying machines will be installed. Of course, only the dehumidifier will be operated, and the remaining two will be out of operation, as well as the dehumidifier. The operation of two vehicles will also be suspended. Therefore, since it is not possible to effectively utilize all of the dehumidifiers that have been installed, dehumidification is required. There was a problem in that the drying ability could not be improved.

[0005] The present invention was made in view of these problems of the conventional technology. The purpose of this is to install multiple grain dryers and dehumidifiers separately. The processing capacity of the grain dryer installed is based on the amount of grain brought into the drying and preparation facility each day. All installed dehumidifiers can be operated to increase the moisture absorption and drying capacity even if the Is it possible to increase drying capacity on a given day? Even when the temperature is relatively low and the drying capacity is low, the heating effect of the auxiliary heating device is Easily improve drying capacity and dry large amounts of grain with good taste. The purpose is to provide a dehumidifying and drying facility that can dry the air.

[0006]

[Means to solve the problem]

In order to achieve the above purpose, the dehumidification drying facility in the present invention is

[0007] One side of the dryer installation building where multiple grain dryers each equipped with a suction/exhaust device are installed. An independent dehumidifier installation room with a dehumidifier installed is installed in the dehumidifier installation room, and the dehumidifier installation room and each It is connected to the dehumidified air intake section of the grain dryer through a centralized duct.

[0008] Then, there is a central pipe that connects the dehumidifier installation room and the dehumidified air intake section of each grain dryer. If an auxiliary heating device is installed inside the duct, the outside temperature is relatively low and the drying capacity is low. Even in the worst case, the temperature of the dehumidified air can be easily raised to further improve the drying capacity can be set.

[0009]

[Effect]

In Figure 1, each dryer installation tank is equipped with a suction and exhaust device, and Install five grain dryers with a capacity of, for example, 20 tons. And one side of the dryer installation building In the dehumidifier installation room, which is installed independently in the For example, five dehumidifiers capable of dehumidifying and drying grains are installed. One dehumidifier may be used as long as it can dehumidify and dry the air. Under the above conditions, if 100 tons of grain is brought into the drying and preparation facility, , After storing 20 tons of grain in each of the five grain dryers, the grain dryer and dehumidifier were installed. When the dehumidifier is operated, the low temperature, low humidity dehumidified air generated by the dehumidifier is passed through the central duct Air is blown from the dehumidified air intake side installed in each grain dryer to circulate and circulate the grain. Sprinkle it on grains to absorb the moisture in the grains and dry them so they taste good. I can do that.

0010 By the way, during the drying work as described above, the amount of grain brought in on that day is For example, if the amount is 50 to 60 tons, store the grain in three grain dryers and store the remaining two. The dehumidifiers will remain inactive, and the five dehumidifiers will continue to operate. In this case, the dehumidifying and drying capacity is increased compared to 100 tons of grain, so the The ability of daily grain drying has been significantly improved, and grains can be dried by hygroscopic action. It can also dry quickly. As a result, three grain machines were Drying operation time is also shortened without increasing the temperature of the drying air to the dryer. , we expect to reduce operating costs (power costs) for the mechanical part by reducing the operating time of grain dryers. I can wait.

[0011] In Figure 2, the outside temperature is relatively low and the dehumidifying and drying capacity of the installed dehumidifier is insufficient to dry the air. If the drying capacity decreases, you should not only operate the dehumidifier but also the auxiliary heating device. The drying capacity can be increased and grains can be dried quickly.

【Example】

Examples will be described with reference to the drawings. In FIG. 1, reference numeral 1 indicates a plurality of grain dryers 4 having a drying capacity of 20 tons, for example. In this embodiment, there are five dryer installation buildings 2 installed (in this example, five dryer installation buildings 2) and one of the dryer installation buildings 2. It is a drying and preparation facility consisting of a dehumidifier installation room 3 installed independently on the side. In the dehumidifier installation room 3, grains (e.g. 20t) can be dehumidified and dried by the moisture absorption action of dehumidified air. A plurality of dehumidifiers 5 (five in this embodiment) are installed. In addition, even if it is one unit, if it is capable of dehumidifying and drying 100 tons of grain, then it is suitable. The number of units does not matter. The grain dryer 4 described above has a dehumidified air intake section 6 on one side and a suction exhaust section on the opposite side. A device 7 is provided, and the stored grain is circulated through a suitable elevator 8. The dehumidifier 5 is of the type that absorbs moisture and dries in the drying section. Air at room temperature was drawn in by a blower and dehumidified by a cooling dehumidifier (evaporator). Any type that can obtain low-temperature air may be used. installed in the plurality of grain dryers 4 installed in the dryer installation building 2. Each of the dehumidified air intake sections 6 and the dehumidifier installation room 3 are connected to multiple central ducts 9. It is connected via..., dehumidified by the dehumidifier 5, and sent into the dehumidifier installation room 3. The dehumidified air is transferred to the dehumidified air intake section 6 by the suction action of the suction exhaust device 7. The grains are supplied to each grain dryer 4 through a central duct 9.

[0013] The one shown in Figure 2 is what happens when the outside temperature is relatively low and the dehumidifying and drying capacity is low. However, by installing the auxiliary heating device 13, grains can be effectively dehumidified and dried. This shows another example of the dehumidifying and drying facility, and in this example, the dryer installation building 2 The removal of multiple grain dryers 4 (in this example, five) installed in the Humid air intake unit 6... and multiple (5 in this embodiment) or one dehumidifier A centralized duct section 1 that communicates with the dehumidifier installation room 3 in which 5... is installed. 0 and a blowing chamber 11 are sequentially arranged, and the concentrated duct section 10 is provided with dehumidified air. An auxiliary heating device 13 is installed to increase the temperature. Note that the ventilation chamber 11 and a dehumidified air intake section 6 provided in each of the plurality of grain dryers 4... A blower 12... is rotatable inside the air duct 14... provided over the air duct 14... There is a storage shaft on the rack. Therefore, with the above configuration, it is possible to further increase the drying capacity. As expected, the number of installed dehumidifiers 5 and auxiliary heating devices 13 is directly related to the number of installed grain dryers 4. If the relationship disappears, many low-cost devices will be installed, or the number of devices will be reduced to increase performance. Drying management can be facilitated by using the powerful dehumidifier 5.

[0014]

[Effect of the idea]

Since the present invention is configured as described above, it produces the following effects. A large amount of grain brought into the drying and preparation facility is stored in multiple grain dryers, and the grain is is slowly removed by the hygroscopic action of the low-temperature, low-humidity dehumidified air obtained by the dehumidifier. It is possible to obtain dried grains that are moist and dry and have good taste, and even if they are delivered on the same day, Even if the amount of dried grain is less than the drying capacity of the installed grain dryer, Regardless of the number of grain dryers installed, the dehumidifier should be operated at full capacity to maximize its moisture absorption and drying capacity. This significantly improves the drying capacity for the same day and shortens the drying operation time. Not only can you easily achieve reductions in size and operating costs (electricity costs), but also the dryer installation building. By separating the dryer and the dehumidifier installation room, the number of grain dryers in operation can be reduced. The number of dehumidifiers operated can be increased or decreased regardless of the size and installation of the dehumidifier. The dry preparation installation layout can be easily arranged without any restrictions. Furthermore, even if the outside temperature is relatively low and the drying capacity is low, the central duct The installed auxiliary heating device raises the temperature of the dehumidified air to increase the dehumidifying and drying capacity. be able to.
