Description

  The present invention relates to a method for increasing the moisture content of soybean.

  Soybean is widely used as a raw material for food and drink such as tofu, natto, oil raising, and soy milk. Soybeans are usually used as a raw material for foods and drinks by mechanically harvesting them with a combine and simultaneously threshing them into beans to dry them using a blower or the like.

  Soybeans used as raw materials for foods and drinks are required to have a moisture content of 15% by mass or less by the agricultural product inspection method, but usually, when the moisture content is high, there is a concern about the occurrence of mold during storage. After threshing, most of the dried soybeans are adjusted to a moisture content of less than 14% by weight. And most of the soybeans that reach the actual demand side through the distribution from the producers are those whose moisture content is less than 14% by mass stored in the warehouse of a wholesaler where humidity is not conditioned, so the moisture content is even less. Therefore, the current situation is about 6 to 12% by mass.

  As a method of storing for a long period of time without deteriorating the quality of the grain, a method of adjusting the storage humidity by sending dehumidified outside air into the intake port of the storage unit has been developed (Patent Document 1). However, in recent years, it has been found that soybeans used for tofu, boiled beans, oil raising, soy milk, etc. tend to have a better flavor of processed soybean foods as the water content is higher. Therefore, in order to increase the water content of soybeans, a method of adding water directly to soybeans put in a retort bag has been developed (Patent Document 2).

  However, in the case of soybean filled in a distribution bag, it is difficult to uniformly add water to the whole soybean without taking out the soybean from the bag, and there is a concern that mold may be generated on the part where much water is attached. . Therefore, various techniques have been developed as a method for increasing the moisture content of soybean without directly adding water to soybean. Such techniques include, for example, a method using a special humidifier (Patent Document 3) that increases the water content to about 15% in order to produce soybeans for sowing that are less susceptible to moisture damage, and the water content of soybeans. In order to increase the water content, grains such as barley and wheat with an excessively high water content are mixed with soybeans with a low water content and stored for several hours. The method (patent document 4) of obtaining is mentioned.

This is a method in which moisture is brought into contact with the soybean filled in the circulation bag by supplying air having a relative humidity of 65% or more by using an apparatus or an air discharge device to increase the moisture of the soybean. The configuration of the present invention will be described below.

[Distribution bags filled with soybeans]
The soybean in the present invention is filled in a distribution bag. The state in which soybeans are filled in the distribution bags refers to the state in which the soybeans are put in the distribution bags. The distribution bags are not particularly limited as long as they are normally used for storage of grains such as soybeans, and for example, “packaging” defined in Article 6 of the Agricultural Products Inspection Law can be used. Examples of the material of the distribution bags include paper (such as kraft paper), flexible container bags, and hemp bags. The shape of the distribution bag is not particularly limited, but in the case of kraft paper, it is usually rectangular. The size of the distribution bag is not particularly limited, but is usually a rectangle having a length of 80 to 90 cm and a width of 40 to 50 cm, and a bottom width of 8 to 12 cm. A distribution bag filled with soybeans can be obtained by filling soybeans in the distribution bags. After filling with soybeans, the distribution bag may be sealed, but may not be sealed. Usually, a distribution bag is sealed by sewing with a sewing thread or tied with a string, and is distributed and / or stored.

  The soybean used in the present invention is not particularly limited, and any of domestic soybean, US soybean such as IOM, genetically modified soybean, or non-genetically modified soybean can be used.

[Aperture]
The distribution bag filled with soybean is provided with at least two openings, and at least one of the openings is provided with an air supply device or an air discharge device, which will be described later, per opening. One can be attached. As will be described later, in the method of the present invention, by operating the air supply device and / or the air discharge device, air having a relative humidity of 65% or more is spread throughout the distribution bag, soy beans in the distribution bag. Can increase moisture.

  When the air supply device or the air discharge device is attached to the opening, it is preferable that the opening is a single hole having a size corresponding to the intake or exhaust of the device. In this case, it is preferable that the shape of the opening is a shape matched to the shape of the intake or exhaust of the apparatus. A cut may be made in the distribution bag (the shape of the cut may be a straight line, etc.), the entire device is put into the bag through the cut, and only the inlet or exhaust port portion is taken out of the bag. Good.

  The opening can be opened by any means for making a hole in the material of the distribution bag. For example, a cutter or a “stab” that is a tool for taking out soybeans from the bag when examining soybeans. Can be used to open a distribution bag.

  On the other hand, when the air supply device or the air discharge device is not attached to the opening, the opening is provided with a plurality of holes (preferably 10 to 10) having a size that allows air to enter and exit and soy does not come out. 200, more preferably 80-200) is preferred. In the case of such an aspect, a range in which a plurality of holes are opened is handled as one opening. In this case, the range of the opening, that is, the range in which the hole is opened in the circulation bag, is preferably within a range of about 5 to 20 cm in length and 5 to 20 cm in width. In addition, as “a plurality of holes of such a size that air can go in and out and air can go in and out and soybeans do not come out”, 10 to 200 pieces of 2 to 5 mm in diameter are used. A hole is mentioned as a preferred embodiment. An arbitrary shape can be selected as the shape of the opening when the air supply device or the air discharge device is not attached to the opening, and it may be a circle, a rectangle, or the like, or may be a shape that is opened using a thousand sheets.

  The position of the opening in the distribution bag is not particularly limited, but it is preferable to provide the openings as far as possible from the viewpoint of facilitating the effects of the present invention by flowing the air in the distribution bag. . For example, when the distribution bag is a vertically long bag and two openings are provided, in order to efficiently distribute air having a relative humidity of 65% or more, which will be described later, throughout the distribution bag, It is preferable to provide openings near both ends of the lower diagonal line (see, for example, FIGS. 1A and 1B and FIG. 2). Here, the “upper part” of the distribution bag refers to the lateral side part of the distribution bag where the soybean filling port is located, and the “lower part” of the distribution bag is the side opposite to the “upper part”. The side part (bottom part) is indicated. When the distribution bag is a vertically long bag and three or more openings are provided, the openings are preferably provided near the four corners of the distribution bag (see, for example, FIG. 3).

  Next, the operation of the present invention when two openings are provided in a distribution bag filled with soybeans will be described.

  When two openings are provided in the distribution bag, as described above, it is preferable to provide openings near both ends of the upper and lower diagonals of the distribution bag. When the air supply device is attached to one of the two openings, and the other opening is formed with a plurality of holes, the inside of the distribution bag is opened from the opening to which the air supply device is attached. Then, air having a relative humidity of 65% or more, which will be described later, is sent in. Next, air is discharged from the other opening having a plurality of holes. By causing the air in the distribution bag to flow in this manner, moisture in the air contacts the soybean in the distribution bag, and the moisture content of the soybean can be increased.

  In order to increase the moisture of soybeans in a shorter time by more efficiently spreading air having a relative humidity of 65% or more, which will be described later, throughout the distribution bag, the opening is an opening having a plurality of holes. Rather than the opening part of the aspect which attached the air exhaust apparatus, it is more preferable.

  When the air exhaust device is attached to one of the two openings, and the other opening is formed with a plurality of holes, the plurality of holes are used for distribution from the opening. Air having a relative humidity of 65% or more, which will be described later, is fed into the bag. Next, air is discharged from the opening to which the other air discharge device is attached. By causing the air in the distribution bag to flow in this manner, moisture in the air contacts the soybean in the distribution bag, and the moisture content of the soybean can be increased.

  In order to more efficiently spread air having a relative humidity of 65% or more, which will be described later, throughout the circulation bag and to increase the moisture of soybeans in a shorter time, the opening is an opening having a plurality of holes. Rather than the opening part of the aspect which attached the air supply apparatus rather than.

[Air supply device and air discharge device]
The present invention is implemented by attaching an air supply device or an air discharge device to at least one opening. And in order to accelerate | stimulate the flow of the air in a distribution bag and to increase the water | moisture content of a soybean efficiently in a short time, an air supply apparatus is provided in the opening part of at least one place provided in the distribution bag. It is preferable that the air discharge device is attached to at least one opening. Also, even number of openings (for example, four places) are provided at both upper and lower ends of the distribution bag, and air supply devices are attached to the upper two openings of the distribution bag for distribution. When an air discharge device is attached to the openings at the two lower portions of the bag (see, for example, FIG. 3), the air in the distribution bag can flow uniformly in a certain direction, and the soybean in the distribution bag The water content can be increased more efficiently.

  The air supply device is a device that can send air into the distribution bag from outside the distribution bag. An air discharge device is a device that discharges air from the distribution bag to the outside of the distribution bag. As the air is discharged, air is drawn into the distribution bag through an opening to which the device is not attached. As a result, a device that can send air into the distribution bag as a result (in other words, by discharging air from the distribution bag, the air is introduced into the distribution bag through the opening to which the device is not attached. A device capable of feeding in).

  Usually, the air supply device has an intake port and an exhaust port. The air supply device sucks air from the intake port and simultaneously discharges air from the exhaust port. Therefore, depending on the mounting method, the air supply device can be used as an air discharge device. Specifically, when the apparatus is operated by attaching the air supply device to the opening of the distribution bag so that the air intake port faces the outside of the distribution bag and the exhaust port faces the inside of the distribution bag, Since air outside the circulation bag is sucked from the intake port and air is sent from the exhaust port into the circulation bag, it functions as an air supply device into the circulation bag. Further, when the apparatus is operated by attaching the air supply device to the opening of the distribution bag so that the exhaust port of the air supply device faces the outside of the distribution bag and the intake port faces the inside of the distribution bag, At the same time as the air in the distribution bag is sucked from the intake port, air is discharged from the exhaust port to the outside of the distribution bag, so that it functions as an air discharge device to the outside of the distribution bag. As air is discharged, air is drawn into the distribution bag through the opening to which the device is not attached, and as a result, air is sent into the distribution bag from the opening to which the device is not attached. be able to.

  The air discharge device also has an intake port and an exhaust port, and at the same time as sucking air from the intake port, the air is discharged from the exhaust port. Therefore, depending on the mounting method, the air discharge device can also be used. Specifically, when the apparatus is operated with the outlet of the distribution bag attached so that the exhaust port of the air discharge device faces the outside of the distribution bag and the intake port faces the inside of the distribution bag, Since air in the distribution bag is sucked from the intake port and air is discharged from the exhaust port to the outside of the distribution bag, it functions as an air discharge device to the outside of the distribution bag. As air is discharged, air is drawn into the distribution bag through the opening to which the device is not attached, and as a result, air is sent into the distribution bag from the opening to which the device is not attached. be able to. Further, when the apparatus is operated by attaching the air supply device to the opening of the distribution bag so that the exhaust port of the air supply device faces the inside of the distribution bag and the intake port of the distribution bag toward the outside of the distribution bag, Air outside the circulation bag is sucked from the intake port and at the same time, air is fed into the distribution bag from the exhaust port, so that it functions as an air supply device into the distribution bag.

  The air supply device is not particularly limited as long as it is a device having a function of feeding air from outside the circulation bag into the circulation bag, and any blower (fan motor) can be used. Since the blower has two functions of sucking air and discharging sucked air, it can be used as an air discharge device depending on the mounting method. When used as an air discharge device, as air is discharged, air is drawn into the distribution bag through the opening to which the device is not attached, resulting in circulation from the opening to which the device is not attached. Air can be sent into the bag.

  When the blower is used as an air supply device, for example, the blower is attached to the opening of the distribution bag with the blower intake port facing the outside of the distribution bag and the blower exhaust port inside the distribution bag. Install it facing. As a specific method of installing the device, after putting a straight cut in a size that allows the device to enter the distribution bag, put the entire device in the distribution bag and take the inlet part out of the bag, It is possible to use a method in which the device is fixed to the distribution bag with a gum tape, and the cut portion is covered with the gum tape so that only the air inlet portion comes out of the bag. Also, after making a hole in the distribution bag that matches the size of the exhaust port of the device, attach the exhaust port part of the device to the hole and fix the device to the distribution bag with gummed tape. Can be used.

  When the attached blower is operated, it draws in air having a relative humidity of 65% or more outside the circulation bag from the intake port, and simultaneously sends air having a relative humidity of 65% or more into the distribution bag from the exhaust port. Works as an air supply device. Although the method of attaching an air supply apparatus to an opening part is not specifically limited, For example, it can fix and attach to a distribution bag with a gummed tape.

  The air discharge device is not particularly limited as long as it is a device having a function of discharging air from the distribution bag to the outside of the distribution bag, and any blower (fan motor) can be used. The blower has two functions: the function of sucking air and the function of discharging the sucked air. Depending on the mounting method, the blower can be used as an air supply device and distributed from outside the distribution bag. Air can be sent into the bag.

  When using the blower as an air discharge device, for example, the blower is attached to the opening of the distribution bag with the blower exhaust port facing the outside of the distribution bag, and the blower intake port is positioned inside the distribution bag. Install it facing. As a specific method of installing the device, after putting a straight cut in a size that allows the device to enter the distribution bag, put the entire device in the distribution bag and take the exhaust port part out of the bag, It is possible to use a method in which the device is fixed to the distribution bag with gum tape, and the cut portion is covered with gum tape so that only the exhaust port portion comes out of the bag. Also, after making a hole in the distribution bag with a size that matches the size of the inlet of the device, attach the inlet portion of the device to the hole and fix the device to the distribution bag with gummed tape. Can be used.

  When the attached blower is operated, the air in the distribution bag is sucked from the intake port and at the same time the air is discharged from the exhaust port to the outside of the distribution bag. Can be sent in. Although the method of attaching an air exhaust apparatus to an opening part is not specifically limited, For example, it can fix and attach to a distribution bag with a gummed tape.

  As a blower that can be used as the air supply device and the air discharge device of the present invention, for example, E0720H series, E1027H series (all manufactured by Nidec Corporation), CFB70-12H, CFB70-12H (all manufactured by Nippon Blower Co., Ltd.) ) And the like.

[Air with a relative humidity of 65% or more]
In the method of the present invention, air having a relative humidity of 65% or more is fed into the circulation bag using an air supply device and / or an air discharge device. By bringing the air of such relative humidity into contact with the soybean in the distribution bag, the moisture content of the soybean can be increased efficiently. From the viewpoint of increasing the moisture content of soybean more efficiently, the relative humidity of the air fed into the circulation bag may be preferably 65 to 95%, more preferably 75 to 95%.

  Whether the air sent into the distribution bag is air having a relative humidity of 65% or more can be confirmed by measuring the humidity near the opening for supplying air using a hygrometer.

  Air having a relative humidity of 65% or more is used for distribution by simply operating the air supply device and / or the air discharge device when the relative humidity of the outside air around the distribution bag filled with soybeans is 65% or more. Although it can be sent into the bag, if the relative humidity is less than 65%, the air supply device and / or the air discharge with the humidifier (Fujita Engineering Co., Ltd., etc.) placed around the circulation bag By operating the apparatus, air having a relative humidity of 65% or more can be fed into the circulation bag. When using a humidifier, etc., in order to efficiently generate air with a relative humidity of 65% or more, the surroundings of the humidifier and the circulation bag are made of airtight materials (plastic bags, plastic sheets, cardboard, etc.). You may cover (for example, refer FIG. 4). When using a humidifier or the like, an illuminator may be installed in order to prevent dew condensation from occurring in the hose that feeds air or in the vinyl sheet.

  Other methods for generating air with a relative humidity of 65% or more include covering the upper surface of the distribution bag or the entire surface with a hemp fabric soaked in water (eg, hemp bag) or grass fabric fabric, and then using a plastic bag. The method of operating an air supply apparatus and / or an air exhaust apparatus in the covered state is mentioned. The water content included in the hemp fabric or the grass fabric may be about 40 to 70% by mass. By spraying water on the hemp fabric or the grass fabric by spraying, or by immersing the hemp fabric or the grass fabric directly in the water and then squeezing lightly, etc., the hemp fabric or the grass grass fabric soaked in water can be obtained. .

  Although it does not specifically limit as time to operate an air supply apparatus and send air with a relative humidity of 65% or more to a distribution | circulation bag, From a viewpoint of making soybeans fully contact with a water | moisture content, Preferably it is 3 to 240 hours. From the viewpoint of shortening the treatment time, it is preferably 5 to 100 hours, more preferably 10 to 24 hours. By increasing the number of air supply devices and the number of openings, the time for feeding air into the circulation bag can be appropriately shortened. The time for sending air into the circulation bag may be continuous or intermittent, and the total time for sending the air into the circulation bag may be in the above range.

  By operating the air exhaust device and exhausting air from the distribution bag, air with a relative humidity of 65% or more is drawn into the distribution bag through the opening to which the device is not attached. Time to send air having a relative humidity of 65% or more into the distribution bag from the opening where the device is not attached (in other words, by operating the air discharge device and discharging the air from the distribution bag, The time during which air having a relative humidity of 65% or more is fed into the distribution bag through the opening that is not attached is not particularly limited, but is preferably 3 to 240 hours from the viewpoint of sufficiently bringing the soybean into contact with moisture. However, from the viewpoint of shortening the treatment time, it is preferably 5 to 100 hours, more preferably 10 to 24 hours. By increasing the number of air discharge devices and the number of openings, the time for discharging air from the circulation bag can be appropriately shortened. The time for discharging air from the circulation bag may be continuous or intermittent, and the total time for discharging air from the circulation bag may be in the above range.

  From the viewpoint of allowing water to easily penetrate into soybean, air having a relative humidity of 65% or more may be sent into the circulation bag under reduced pressure conditions.

  The other conditions for carrying out the present invention are not particularly limited, but from the viewpoint of preventing the oxidation of lipids in soybeans and suppressing the deterioration of flavor due to the deterioration of soybeans, the temperature in the distribution bag is 10 to 25 ° C. The temperature may be 10 to 20 ° C, more preferably 10 to 15 ° C.

  The present invention may be carried out in a mode in which an opening is provided in a single distribution bag filled with soybeans and air with a relative humidity of 65% or more is fed into the distribution bag. It is also possible to carry out an embodiment in which two or more bags are stacked and an opening is provided in each distribution bag, and air having a relative humidity of 65% or more is fed into each distribution bag. Even if air having a relative humidity of 65% or more is fed into the distribution bags in a state where a plurality of distribution bags are stacked, the air flows in each distribution bag, so that the soybean can be brought into contact with moisture. . Therefore, according to the present invention, it is possible to efficiently increase the moisture content of soybeans without removing the soybeans from the distribution bags. Can be processed simultaneously.

  After increasing the moisture content of soybeans by sending air with a relative humidity of 65% or more into the circulation bag, generation of humidified air is stopped, and the air supply device and / or the air discharge device are continuously operated to perform humidification. By sending the outside air around the circulation bag that is not present into the circulation bag, the difference (unevenness) in the local moisture content of soybeans in the circulation bag can be reduced.

  By the method of the present invention, the moisture content of soybeans in the distribution bag can be increased. The moisture content to be increased can be adjusted by the relative humidity value of the air fed into the distribution bag described above, and the operating time of the air supply device or the air discharge device. By adjusting them appropriately, the water | moisture content of the soybean in a distribution bag can be increased about 1-10 mass%.

  For example, according to the method of the present invention, the moisture content of soybeans in a distribution bag having a moisture content of 6% by mass to less than 13% by mass can be increased to 13-20% by mass. Moreover, the moisture content of the soybean in the 13-14 mass% distribution | circulation bag can be increased to 15-25 mass%.

  Whether or not the water content of soybeans has been increased by the present invention can be confirmed by comparing the water content of soybeans before and after performing the method of the present invention.

The soybean water content before the implementation of the present invention (at the start of the present invention) is determined by taking out the soybeans in the distribution bag, and using a high-frequency grain moisture meter (PM-600, manufactured by Kett Science Laboratory Co., Ltd.) It can be measured by the method (method of drying a ground product of 3 g of soybean at 105 ° C. for 4 hours). Moreover, the water content (mass%) of soybeans in the distribution bag after the present invention can be calculated using (Equation 1).
(Formula 1)
Soybean moisture content (% by mass) = total soybean moisture in distribution bag / total soybean mass in distribution bag × 100
In (Formula 1), the “total mass of soybean water in the distribution bag” (unit: kg) is the value obtained by subtracting the dry mass of soybean from the total mass of soybean in the distribution bag. (Unit: kg) can be obtained from the following equation.
(Formula 2)
Soybean dry mass (kg) = total soybean mass at start-total soybean water mass at start (Formula 2), the total water mass (unit: kg) of soybean at the start is determined by the following formula be able to.
(Formula 3)
Total Soybean Moisture at Start = Total Soybean Mass at Start × Soy Moisture Content at Start / 100

  Soybeans whose water content has been increased by the method for increasing water content of soybeans of the present invention can be used as raw materials for tofu, boiled beans, oil raising and soy milk in the same manner as normal soybeans which have not been subjected to a water content increasing process. . Soybean processed foods such as tofu, natto, oil-raising, soymilk, etc. made from soybeans whose water content has been increased to 13-25% by weight are more flavored than soybean processed foods made from soybeans before the water content is increased. Will be good.

  Moreover, the soybean whose water content has been increased to about 15% by mass by the method for increasing the moisture content of soybean of the present invention can be used as a soy seed for sowing that is less susceptible to moisture damage.

In the following, a paper bag consisting of four layers of kraft paper as defined in JIS was used as a distribution bag. The air supply device and the air discharge device were used by covering the whole with an onion net. The air supply device was operated by attaching the inlet of the device to the outside of the circulation bag and attaching the exhaust port of the device to the inside of the circulation bag at the opening of the circulation bag. In addition, the air discharge device was operated by attaching the exhaust port of the device to the outside of the distribution bag and the intake port of the device facing the inside of the distribution bag at the opening of the distribution bag.

<Example 1: Investigation using an air supply device (1 unit)>
As shown in FIG. 1 (A), two openings were provided in the vicinity of both ends on the diagonal line of the distribution bag filled with soybean (30 kg). An opening to which an air supply device (E1027H12BAAZ-00 (12V, 1000 mA), size: about 8.5 cm in length, about 9.7 cm in width, about 3.0 cm in thickness, manufactured by Nidec Corporation) is attached is air It is a hole drilled to match the size of the exhaust port of the supply device. The air supply device was attached to the opening by attaching the exhaust port portion of the air supply device to the hole and fixing the device to the distribution bag with gummed tape. The other opening is a square part with a diameter of about 10 cm and a width of about 10 cm with 100 holes with a diameter of about 3 mm. The hole allows air to enter and exit, and soy does not come out. Of the size. In the following, the arrows in the figure indicate the direction of air flow.

  Next, the entire distribution bag is covered with a water-soaked hemp bag (the dried hemp bag is 0.75 kg, and the water-filled hemp bag is 1.8 kg) and covered with a plastic bag. It was. By operating the air supply device in this state, air having a relative humidity of 65% or more generated by evaporation of moisture from the hemp bag was sent into the circulation bag.

  Table 1 shows the moisture content of soybeans in the distribution bags before the operation of the air supply device (hereinafter, the time before the operation of the air supply device or the air discharge device is also referred to as “start time”) and after 24 hours of operation. Shown in

  The moisture content of soybean in the bag at the start was measured as follows. That is, 75 g of soybean was taken out from the distribution bag, the moisture content was measured with a high-frequency moisture meter, and the obtained value was taken as the moisture content (mass%) of soybean at the start.

Moreover, the water content (unit: mass%) of soybean in the distribution bag after operation of the air supply device was calculated using (Formula 1).
(Formula 1)
Soybean moisture content (% by mass) = total soybean moisture in distribution bag / total soybean mass in distribution bag × 100
In (Formula 1), “total water content of soybean in distribution bag” (unit: kg) is a value obtained by subtracting the dry mass of soybean from the total mass of soybean in distribution bag. The dry mass (unit: kg) of soybean was calculated using (Formula 2).
(Formula 2)
Soybean dry mass (kg) = total soybean mass at the start-total soybean water mass at the start (Formula 2), "total soybean water mass at the start" (unit: kg) is the following formula Determined by
(Formula 3)
Total Soybean Moisture at Start = Total Soybean Mass at Start × Soy Moisture Content at Start / 100

  As shown in Table 1, by carrying out the present invention, it was possible to increase the moisture content of soybean in the distribution bag without performing the operation of taking out and putting in the soybean from the distribution bag.

  Therefore, according to the present invention, it is a relatively simple operation (that is, it is not necessary to put and take out soybeans from the bag), and the soybean surface is not damaged by taking in and out soybeans from the bag. It was found that the moisture content of soybean can be increased.

  However, in the case of this example (an example in which an air supply device (one piece) is used), the soybean content is higher than that in Example 3 (an example in which an air supply device (one piece) and an air discharge device (one piece) are used) described later. The effect of increasing the water content may be low. However, in this example, an effect equivalent to that of the third embodiment can be obtained by operating the air supply device for a longer time.

<Example 2: Investigation using an air discharge device (1 piece)>
As shown in FIG. 1 (B), two openings were provided near both ends on the diagonal line of the distribution bag filled with soybean (30 kg). The opening to which the air discharge device (E1027H12BAAZ-00 (12V, 1000 mA), size: about 8.5 cm in length, about 9.7 cm in width, about 3.0 cm in thickness, manufactured by Nidec Corporation) is attached is air The hole is sized according to the size of the exhaust port of the discharge device. After making a straight cut in the distribution bag that is large enough to accommodate the air discharge device, put the entire device in the distribution bag and take the exhaust port out of the bag. The cut portion was fixed with gummed tape so that only the exhaust port portion was out of the bag, and the air exhaust device was attached to the opening. The other opening is an area in which 100 holes with a diameter of about 3 mm are formed in a square part of about 10 cm in length and about 10 cm in width, and the hole allows air to enter and exit, and soy does not come out. Of the size.

  Next, the entire distribution bag is covered with a water-soaked hemp bag (the dried hemp bag is 0.75 kg, and the water-filled hemp bag is 1.8 kg) and covered with a plastic bag. It was. By operating the air discharge device in this state, air having a relative humidity of 65% or more generated by the evaporation of water from the hemp bag is distributed through the other opening (the region having 100 holes). I sent it in.

  Table 2 shows the moisture content of soybeans in the distribution bags before the operation of the air discharge device (at the start), after the operation for 24 hours, after the operation for 48 hours, and after the operation for 72 hours. The moisture content of soybean at the start and the moisture content of soybean at each time after operation were calculated in the same manner as in Example 1.

  As shown in Table 2, by carrying out the present invention, it was possible to increase the water content of soybean in the distribution bag without performing the operation of taking out and putting in the soybean from the distribution bag.

  Therefore, according to the present invention, it is a relatively simple operation (that is, it is not necessary to put and take out soybeans from the bag), and the soybean surface is not damaged by taking in and out soybeans from the bag. It was found that the moisture content of soybean can be increased.

  However, in the case of this example (example using an air discharge device (one piece)), soybean is used more than in Example 3 (example using an air supply device (one piece) and an air discharge device (one piece)) described later. There is a possibility that the effect of increasing the water content is low. However, in this example, the same effect as in Example 3 can be obtained by operating the air discharge device for a longer time.

<Example 3: Investigation using an air supply device (1 piece) and an air discharge device (1 piece)>
As shown in FIG. 2, two openings were provided in the vicinity of both ends on the diagonal line of the distribution bag filled with soybean (30 kg). The opening to which the air supply device (E0720H12B8AZ-00 (12V, 200 mA), size: about 7.5 cm in length, about 7.3 cm in width, about 2.0 cm in thickness, manufactured by Nidec Corporation) is attached is air It is a hole drilled to match the size of the exhaust port of the supply device. The air supply device was attached to the opening by attaching the exhaust port portion of the air supply device to the hole and fixing the device to the distribution bag with gummed tape. The other opening to which the air discharge device (E1027H12BAAZ-00 (12V, 1000 mA), size: about 8.5 cm in length, about 9.7 cm in width, about 3.0 cm in thickness, manufactured by Nidec Corporation) is attached Is a hole of a size matching the size of the exhaust port of the device. After making a straight cut in the distribution bag that is large enough to accommodate the air discharge device, put the entire device in the distribution bag and take the exhaust port out of the bag. The cut portion was fixed with gummed tape so that only the exhaust port portion was out of the bag, and the air exhaust device was attached to the opening.

  Next, a hemp bag soaked in water (0.65 kg for the dried hemp bag and 1.7 kg for the hemp bag after addition) was covered over the entire distribution bag, and covered with a plastic bag. It was. By operating the air supply device and the air discharge device for 24 hours in this state, air having a relative humidity of 65% or more generated by evaporation of moisture from the hemp bag was sent into the circulation bag.

  Table 3 shows the moisture content of soybeans in the distribution bags before the operation of the air supply device and the air discharge device (at the start) and after the operation for 24 hours. The moisture content of soybean at the start and the moisture content of soybean after operation were calculated in the same manner as in Example 1.

  As shown in Table 3, by carrying out the present invention, it was possible to increase the moisture content of soybeans in the distribution bags without performing the operation of taking out and taking out soybeans from the distribution bags.

  Therefore, according to the present invention, it is a relatively simple operation (that is, it is not necessary to put and take out soybeans from the bag), and the soybean surface is not damaged by taking in and out soybeans from the bag. It was found that the moisture content of soybean can be increased.

  In this example (an example using an air supply device (1 piece) and an air discharge device (1 piece)), Example 1 (example using an air supply device (1 piece)) or Example 2 (air discharge) It was found that the moisture content of soybean can be increased more efficiently than in the case of using an apparatus (one).

<Example 4: Study using air supply device (2 pieces) and air discharge device (2 pieces)>
As shown in FIG. 3, four openings were provided at positions close to the four corners of the distribution bag filled with soybean (30 kg). Among the four openings, an air supply device (E0720H12B8AZ-00 (12V, 200 mA), size: about 7.5 cm in length, about 7.3 cm in width, about 2.0 cm in thickness, manufactured by Nidec Corporation) The two attached openings are holes sized to match the exhaust port of the device. The air supply device was attached to the opening by attaching the exhaust port portion of the air supply device to the hole and fixing the device to the distribution bag with gummed tape. Moreover, the remaining 2 which attached the air exhaust device (E0720H12B8AZ-00 (12V, 200mA), size: about 7.5 cm in length, about 7.3 cm in width, about 2.0 cm in thickness, made by Nidec Corporation) The two openings are holes sized according to the size of the exhaust port of the apparatus. After making a straight cut in the distribution bag that is large enough to accommodate the air discharge device, put the entire device in the distribution bag and take the exhaust port out of the bag. The cut portion was fixed with gummed tape so that only the exhaust port portion was out of the bag, and the air exhaust device was attached to the opening.

  Next, the entire distribution bag is covered with a water-soaked hemp bag (the dried hemp bag is 0.75 kg, and the water-filled hemp bag is 1.8 kg) and covered with a plastic bag. It was. By operating the air supply device and the air discharge device for 12 hours in this state, air having a relative humidity of 65% or more generated by evaporation of moisture from the hemp bag was sent into the circulation bag.

  Table 4 shows the moisture content of soybeans in the distribution bags before the operation of the air supply device and the air discharge device (at the start) and after the operation for 12 hours. The moisture content of soybean at the start and the moisture content of soybean after operation were calculated in the same manner as in Example 1.

  As shown in Table 4, by carrying out the present invention, it was possible to increase the water content of soybean in the distribution bag without performing the operation of taking out and putting in the soybean from the distribution bag.

  Therefore, according to the present invention, it is a relatively simple operation (that is, it is not necessary to put and take out soybeans from the bag), and the soybean surface is not damaged by taking in and out soybeans from the bag. It was found that the moisture content of soybean can be increased.

  In this example (an example using two air supply devices and two air discharge devices), Example 3 (an example using one air supply device and one air discharge device) is used. It was found that the moisture content of soybeans can be increased efficiently in a significantly shorter time compared to.

<Example 5: Study using air supply device (1 piece) and air discharge device (1 piece)>
Two openings were provided in the vicinity of both ends on the diagonal of the distribution bag filled with soybean (30 kg). The opening to which the air supply device (E0720H12B8AZ-00 (12V, 200 mA), size: about 7.5 cm in length, about 7.3 cm in width, about 2.0 cm in thickness, manufactured by Nidec Corporation) is attached is air It is a hole drilled to match the size of the exhaust port of the supply device. The air supply device was attached to the opening by attaching the exhaust port portion of the air supply device to the hole and fixing the device to the distribution bag with gummed tape. The other opening to which the air exhaust device (E0720H12B8AZ-00 (12V, 200 mA), size: about 7.5 cm in length, about 7.3 cm in width, about 2.0 cm in thickness, manufactured by Nidec Corporation) is attached Is a hole drilled according to the size of the exhaust port of the device. After making a straight cut in the distribution bag that is large enough to accommodate the air discharge device, put the entire device in the distribution bag and take the exhaust port out of the bag. The cut portion was fixed with gummed tape so that only the exhaust port portion was out of the bag, and the air exhaust device was attached to the opening.

  Prepare two distribution bags filled with soybeans, equipped with an air supply device (1 piece) and an air discharge device (1 piece) as described above, stack the distribution bags up and down, and corrugate around them. Then, the entire corrugated cardboard surrounding the two bags for distribution and the exhaust port of the humidifier (Fujita Engineering Co., Ltd.) were covered with a vinyl sheet. The humidifier was activated and air with a relative humidity of 83% was sent into the space covered with the vinyl sheet. In this state, the air supply device and the air discharge device were operated for 5 days, and air with a relative humidity of 83% generated from the humidifier was sent into the circulation bag.

  Table 5 shows the moisture content of soybeans in the distribution bags before the operation of the air supply device and the air discharge device (at the start) and after the operation for 5 days. The moisture content of soybean at the start and the moisture content of soybean after operation were calculated in the same manner as in Example 1. Further, in Table 5, “upper” indicates a bag stacked on the upper side among the distribution bags stacked in two bags, and “lower” indicates a bag placed on the lower side.

  As shown in Table 5, by carrying out the present invention, the soybeans in the distribution bag can be obtained even if the operation of adding and removing soybeans from the distribution bag is not performed and the distribution bags are stacked. The water content of can be increased.

  Therefore, according to the present invention, it is a relatively simple operation (that is, it is not necessary to put and take out soybeans from the bag), and the soybean surface is not damaged by taking in and out soybeans from the bag. The water content of soybeans can be increased, and since the distribution bags can be stacked, it can be seen that the present invention can be implemented for many distribution bags at once in a small space. It was.

  As shown in Table 5, even if the present invention is carried out in a state where the distribution bags are stacked, the moisture content of soybeans in the distribution bags stacked above and the moisture content of soybeans in the distribution bags placed below Were approximately the same value, and the total moisture content of soybeans could be increased at a rate of about 200 g / day for 30 kg of soybeans per bag.
