次に、殺虫及び殺菌装置１を用いて、穀物を殺虫及び殺菌する方法について説明する。
Next, a method of killing and sterilizing grains using the insecticidal and sterilizing device 1 will be described.
まず、加水部１０の筐体１１に穀物を投入し、筐体１１の内部に突出する第１ノズル１８の一端部から、タンク部１７に貯留されている水を穀物に向けて噴射する。このとき穀物に噴射される、穀物の質量に対する水の質量は、５質量％以上１０質量％以下であることが好ましい。
First, the grain is put into the housing 11 of the water addition portion 10, and the water stored in the tank portion 17 is sprayed toward the grain from one end of the first nozzle 18 protruding inside the housing 11. At this time, the mass of water sprayed on the grain with respect to the mass of the grain is preferably 5% by mass or more and 10% by mass or less.
また、このとき、穀物に効率的に水を噴射するために、加水部１０の内部を落下移動している穀物に対して、予め規定した所定の量の水を噴射する。このような穀物に水を噴射する噴射工程により、穀物の表面全体に、加熱部１９で効率的に殺虫及び殺菌するための水の層が形成される。
Further, at this time, in order to efficiently spray water on the grain, a predetermined amount of water specified in advance is sprayed on the grain falling and moving inside the water addition portion 10. By the injection step of injecting water onto the grain, a layer of water for efficiently killing and sterilizing the insect is formed on the entire surface of the grain by the heating unit 19.
加水部１０で水を噴射された穀物は、管状部１５を介して加熱部１９に移動する。加熱部１９に移動した穀物は第１回転部材２１の回転に伴い、第１筒状部２０の一端部側から他端部側に向かって移動する。加熱部１９を穀物が移動する際、噴射部２２は、所定の温度に加熱された蒸気を第１筒状部２０の内部空間に噴射する。このような加熱工程により、加水部１０において穀物に付与された水の少なくとも一部に対して、加熱部１９で蒸気を付与させることができ、穀物に付与された水の少なくとも一部を加熱し、効率よく穀物の殺虫及び殺菌を行うことができる。また、第１回転部材２１が第１螺旋状部２４を有することにより、穀物の加熱と、穀物の乾燥部３０までの搬送と、を効率的に行わせることができる。
The grain sprayed with water in the water addition portion 10 moves to the heating portion 19 via the tubular portion 15. The grain that has moved to the heating unit 19 moves from one end side to the other end side of the first tubular portion 20 as the first rotating member 21 rotates. When the grain moves through the heating unit 19, the injection unit 22 injects steam heated to a predetermined temperature into the internal space of the first tubular portion 20. By such a heating step, steam can be applied to at least a part of the water given to the grain in the water addition part 10 by the heating part 19, and at least a part of the water given to the grain is heated by the heating part 19. , It is possible to efficiently kill and sterilize grains.

The grain sprayed with steam in the heating unit 19 is conveyed to the drying unit 30 connected to the heating unit 19. The grain that has moved to the drying portion 30 moves from one end side to the other end side of the second tubular portion 26 as the second rotating member 27 rotates. When the grain moves through the drying section 30, the blowing section 28 blows the air heated to a predetermined temperature to at least one of the grain, water, and steam conveyed from the heating section 19. By such a blowing step, at least one of water and steam can be separated from the grain, and the grain can be dried. Further, since the second rotating member 27 has the second spiral portion 32, the grain can be efficiently dried and transported to the carry-out portion 40.
また、第２筒状部２６の下部に設けられた異物受容部２９には、穀物の乾燥と、搬出部４０までの搬送と、がされることに伴って生じる異物が第２筒状部２６のスリットを通過して落下し、異物は殺虫及び殺菌装置１の外部に適宜搬出される。
Further, in the foreign matter receiving portion 29 provided at the lower part of the second tubular portion 26, the foreign matter generated as a result of the drying of the grain and the transport to the carry-out portion 40 is carried out in the second tubular portion 26. It falls through the slit of the above, and the foreign matter is appropriately carried out to the outside of the insecticidal and sterilizing device 1.
乾燥処理を施された穀物は、第２筒状部２６の搬出部４０から搬出され、殺虫及び殺菌処理が終了する。
The dried grain is carried out from the carrying-out part 40 of the second tubular part 26, and the insecticidal and sterilizing treatment is completed.
殺虫及び殺菌装置１が、実施の形態２で説明した脱水部３３を有する場合には、
加熱部１９で蒸気を噴射された穀物は、加熱部１９に接続する脱水部３３に搬送される。脱水部３３に移動した穀物は第３回転部材３６の回転に伴い、小筐体３４及び大筐体３５の内部を、上部から下部に向かって移動する。脱水部３３を穀物が移動する際、第３回転部材３６の回動により、水及び蒸気の少なくとも１つが穀物から分離する。穀物から分離した水及び蒸気の少なくとも１つは、排出部から殺虫及び殺菌装置１の外部に排出される。また、水及び蒸気の少なくとも１つを分離された穀物は、第３回転部材３６により、乾燥部３０に搬送される。 When the insecticidal and sterilizing device 1 has the dehydratingunit 33 described in the second embodiment,
The grain sprayed with steam in theheating unit 19 is conveyed to the dehydration unit 33 connected to the heating unit 19. The grain that has moved to the dehydration section 33 moves from the upper part to the lower part inside the small housing 34 and the large housing 35 as the third rotating member 36 rotates. When the grain moves through the dehydration section 33, the rotation of the third rotating member 36 separates at least one of water and steam from the grain. At least one of the water and steam separated from the grain is discharged from the discharge part to the outside of the insecticidal and sterilizing device 1. Further, the grain from which at least one of water and steam is separated is conveyed to the drying unit 30 by the third rotating member 36.
加熱部１９で蒸気を噴射された穀物は、加熱部１９に接続する脱水部３３に搬送される。脱水部３３に移動した穀物は第３回転部材３６の回転に伴い、小筐体３４及び大筐体３５の内部を、上部から下部に向かって移動する。脱水部３３を穀物が移動する際、第３回転部材３６の回動により、水及び蒸気の少なくとも１つが穀物から分離する。穀物から分離した水及び蒸気の少なくとも１つは、排出部から殺虫及び殺菌装置１の外部に排出される。また、水及び蒸気の少なくとも１つを分離された穀物は、第３回転部材３６により、乾燥部３０に搬送される。 When the insecticidal and sterilizing device 1 has the dehydrating

また、本実施の形態では、第２筒状部２６に複数のスリットが設けられている形態を例示して説明したが、充分な乾燥機能を奏するのであれば、スリットの数は任意である。
Further, in the present embodiment, the embodiment in which a plurality of slits are provided in the second tubular portion 26 has been described as an example, but the number of slits is arbitrary as long as it has a sufficient drying function.
また、異物受容部２９の内部に仕切板４２を設けることにより、異物受容部２９の内部空間を複数の空間に区画してもよい。このとき、仕切板４２は、第２筒状部２６の長手軸に垂直方向に設けられる。これにより、仕切板４２は、異物受容部２９の内部空間を、殺虫及び殺菌装置１の延在方向に区画できる。そのため、区画された内部空間ごとに、例えば温度、風量などの乾燥条件を変更することができる。例えば、異物受容部２９の内部空間を２つの空間に区画する場合には、第２筒状部２６の一端部側の異物受容部２９の内部空間には、比較的温度が高く、かつ、多量の風を送風することができる。一方で、第２筒状部２６の他端部側の異物受容部２９の内部空間には、比較的温度が低く、かつ、少量の風を送風することができる。
Further, the internal space of the foreign matter receiving portion 29 may be divided into a plurality of spaces by providing the partition plate 42 inside the foreign matter receiving portion 29. At this time, the partition plate 42 is provided in the direction perpendicular to the longitudinal axis of the second tubular portion 26. As a result, the partition plate 42 can partition the internal space of the foreign matter receiving portion 29 in the extending direction of the insecticidal and sterilizing device 1. Therefore, it is possible to change the drying conditions such as temperature and air volume for each partitioned internal space. For example, when the internal space of the foreign matter receiving portion 29 is divided into two spaces, the internal space of the foreign matter receiving portion 29 on the one end side of the second tubular portion 26 has a relatively high temperature and a large amount. Can blow the wind. On the other hand, the temperature is relatively low and a small amount of air can be blown into the internal space of the foreign matter receiving portion 29 on the other end side of the second tubular portion 26.
また、本実施の形態では、ブロワを例に送風部２８を説明したが、これに限定されない。例えば、送風部２８は、回転軸の周方向に、環状かつ等間隔に配設された複数の羽根車を備える部材であってもよい。送風部２８に設けられる羽根車は、図示しない駆動源から駆動力を与えられることにより、回転軸を中心として回転可能である。
Further, in the present embodiment, the blower section 28 has been described by taking a blower as an example, but the present invention is not limited to this. For example, the blower portion 28 may be a member including a plurality of impellers arranged in an annular shape and at equal intervals in the circumferential direction of the rotation shaft. The impeller provided in the blower portion 28 can rotate about a rotation axis by applying a driving force from a drive source (not shown).
また、異物受容部２９の内部空間を複数の空間に区画する場合には、区画された空間に対応する個数、送風部２８を設けることができる。例えば、図１０に示すように、異物受容部２９の内部空間を２つの空間に区画する場合には、第２筒状部２６の一端部側の異物受容部２９の内部空間には、６０℃以上８０℃以下の風の温度、かつ、７０ｍ３／ｍｉｎ以上９０ｍ３／ｍｉｎ以下の風量で送風することが好ましい。一方で、第２筒状部２６の他端部側の異物受容部２９の内部空間には、３０℃以上５０℃以下の風の温度、かつ、５０ｍ３／ｍｉｎ以上７０ｍ３／ｍｉｎ以下の風量で送風することが好ましい。
Further, when the internal space of the foreign matter receiving unit 29 is divided into a plurality of spaces, the number of blower units 28 corresponding to the divided spaces can be provided. For example, as shown in FIG. 10, when the internal space of the foreign matter receiving portion 29 is divided into two spaces, the internal space of the foreign matter receiving portion 29 on the one end side of the second tubular portion 26 has a temperature of 60 ° C. It is preferable to blow air at a wind temperature of 80 ° C. or higher and an air volume of 70 m 3 / min or more and 90 m 3 / min or less. On the other hand, in the internal space of the foreign matter receiving portion 29 on the other end side of the second tubular portion 26, the air temperature is 30 ° C. or higher and 50 ° C. or lower, and the air volume is 50 m 3 / min or higher and 70 m 3 / min or lower. It is preferable to blow air with.
このように、異物受容部２９の内部空間を複数の空間に区画することにより、送風部２８から、異なる温度を有する風を、異なる風量でも各空間に送風することが可能となり、第２筒状部２６の他端部側に向かうにつれて効率的に冷却処理も行うことができる。
By partitioning the internal space of the foreign matter receiving unit 29 into a plurality of spaces in this way, it becomes possible to blow air having different temperatures into each space from the air blowing unit 28 even with different air volumes, and the second tubular shape. The cooling process can be efficiently performed toward the other end side of the portion 26.
また、本実施の形態２では、遠心分離により、穀物の表面から水及び蒸気の少なくとも１つを分離させる脱水部３３を例示して説明したが、これに限定されない。充分に穀物の表面から水及び蒸気の少なくとも１つを分離させることができるのであれば、例えば、図示しない吸引機能を有する脱水部を用いてもよい。
