Description

本発明は、容器内に投入した被処理物に対し、外部から供給する高温蒸気や空気等の乾燥用流体を容器内に備える攪拌手段から噴射しながら攪拌して、被処理物の乾燥や殺菌を行ったり、また、同攪拌手段から液体や粉体等の流体を噴射しながら攪拌して、被処理物と液体や粉体等の流体とを混合できるようにした乾燥装置を兼用する攪拌装置に関する。   The present invention stirs an object to be processed put into the container while spraying a drying fluid such as high-temperature steam or air supplied from outside from an agitation means provided in the container to dry or sterilize the object to be processed. And a stirring device that also serves as a drying device that mixes the object to be processed and a fluid such as liquid or powder by stirring while jetting a fluid such as liquid or powder from the stirring means About.

従来、外部から供給される蒸気を容器内の攪拌手段から噴射して、被攪拌物である例えば植物栽培に用いる植栽土壌の乾燥や殺菌等を行う攪拌装置がある（例えば、特許文献１参照）。   2. Description of the Related Art Conventionally, there is an agitation apparatus that sprays steam supplied from the outside from an agitation means in a container to dry or sterilize planted soil used for plant cultivation, for example (see, for example, Patent Document 1). ).

この攪拌装置は、外部から供給される乾燥や殺菌等に用いる蒸気を、被攪拌物を攪拌するための攪拌羽根を取り付けている水平軸、また水平軸および攪拌羽根から被攪拌物に対し噴射して行っている。   This stirrer sprays steam used for drying, sterilization, etc. supplied from the outside to the object to be stirred from the horizontal axis to which the stirring blade for stirring the object to be stirred is attached, and from the horizontal axis and the stirring blade. Is going.

しかしながら、被攪拌物は攪拌羽根により大に攪拌されるので、被攪拌物の容器内における攪拌羽根の通過前後における位置が、蒸気を噴射している攪拌羽根から蒸気が殆ど届かない水平軸方向の左右攪拌羽根の中間地点まで攪拌により大に変位してしまい、攪拌羽根から噴射された蒸気が多く当たる被攪拌物と少ししか当たらない被攪拌物が生じてしまう恐れがあり、したがって蒸気を噴射している時間すなわち被攪拌物を殺菌するための殺菌時間が短い場合は、被攪拌物の中に殺菌が不充分なものが存在する恐れがあった。   However, since the agitated material is greatly agitated by the agitating blade, the position of the agitated material before and after the passage of the agitating blade is in the horizontal axis direction where the steam hardly reaches from the agitating blade that is injecting the steam. Due to stirring, the middle point of the left and right stirring blades is greatly displaced, and there is a risk that a target to be stirred with a large amount of steam sprayed from the stirring blades and a target to be stirred with little impact may be generated. If the sterilization time for sterilizing the object to be stirred is short, there is a possibility that some of the objects to be stirred are insufficiently sterilized.

特許３６７３８１３号公報（第１〜８頁、図１〜７）Japanese Patent No. 3673813 (pages 1-8, FIGS. 1-7)

また、本発明に係る乾燥装置を兼用する攪拌装置における乾燥装置は、容器内にて被処理物となる被乾燥物を攪拌しながら乾燥させる際、被乾燥物に対し外部から供給される所定の乾燥用流体を容器内の攪拌手段から噴射して行う乾燥装置であって、攪拌手段を、回転軸と、この回転軸の周囲に軸の遠心方向に突設した複数の棒状体から構成して、回転軸を、少なくとも底部内面が内側に湾曲する容器における底部内面の湾曲方向に対し直交させ、かつ棒状体の先端が底部の湾曲面を通過する際、棒状体の先端と湾曲面との間に小なる隙間を有し湾曲面に沿って通過できるように設け、乾燥用流体を棒状体から回転軸に略平行に噴射させるように構成したものとし、また前記乾燥用流体を、高温蒸気、低温乃至高温の空気としたものとしてある。   Further, the drying device in the stirring device that also serves as the drying device according to the present invention provides a predetermined supply supplied from the outside to the material to be dried when drying the material to be processed in the container while stirring. A drying apparatus that performs spraying of a drying fluid from stirring means in a container, and the stirring means includes a rotating shaft and a plurality of rod-like bodies protruding around the rotating shaft in the centrifugal direction of the shaft. The rotation axis is at least perpendicular to the bending direction of the bottom inner surface of the container whose inner surface is curved inward, and when the tip of the rod-like body passes through the curved surface of the bottom portion, Provided so as to be able to pass along a curved surface, and configured to inject the drying fluid from the rod-like body substantially parallel to the rotation axis. As low-temperature to high-temperature air .

また前記棒状体を、回転軸の軸方向に等間隔で設けるとともに、各棒状体を一方向に等角度ずらしながら螺旋状に軸の周囲に配置したものとしてある。   In addition, the rod-shaped bodies are provided at equal intervals in the axial direction of the rotation shaft, and the rod-shaped bodies are spirally arranged around the shaft while being shifted by an equal angle in one direction.

また前記乾燥用流体を、回転軸および棒状体の内部に形成した導通路に通過させるとともに、この導通路に続く棒状体に形成した噴射口から噴射させるように構成したものとしてある。   Further, the drying fluid is configured to pass through a conduction path formed inside the rotary shaft and the rod-shaped body, and to be ejected from an ejection port formed in the rod-shaped body following the conduction path.

さらに前記回転軸の周囲に、棒状体の配置周期に対応するよう螺旋状の羽根を設けるとともに、羽根の先端と湾曲する底部内面との間に小なる隙間が空くように設けたものとしてある。   Further, spiral blades are provided around the rotation shaft so as to correspond to the arrangement period of the rod-shaped bodies, and a small gap is provided between the tip of the blade and the curved bottom inner surface.

本発明の乾燥装置を兼用する攪拌装置によれば、被処理物となる被乾燥物や被攪拌物を回転軸の周囲に軸の遠心方向に適数突設されている棒状体で攪拌しているため、被処理物は棒状体の通過方向に対し左右方向に押し退けられるように攪拌されるので、棒状体の通過前後における被処理物の変位を小にできて、したがって被処理物は各棒状体の近傍に留まりながら攪拌される。   According to the stirrer that also serves as the drying apparatus of the present invention, the to-be-processed object and the object to be stirred are stirred with a rod-like body that is provided in a proper number around the rotating shaft in the centrifugal direction of the shaft. Therefore, the object to be processed is stirred so that it is pushed away in the left-right direction with respect to the passing direction of the rod-shaped body, so that the displacement of the object to be processed before and after the passage of the rod-shaped body can be reduced. It is stirred while staying in the vicinity of the body.

かくして、被処理物となる被乾燥物を乾燥また殺菌する場合は、回転軸の周囲に被乾燥物の量に対応できるよう軸の遠心方向に突設した棒状体からこの水平軸の軸方向に高温蒸気を噴射することで、被乾燥物はこの高温蒸気により棒状体の周囲から棒状体の遠心方向に向かって順次乾燥また殺菌されて行くので、したがって短時間で乾燥また殺菌を充分に行うことができる。
また、回転軸の周囲に配設した棒状体から液体や粉体等の流体を噴射して被処理物となる被攪拌物と液体や粉体等の流体とを攪拌しながら混合する場合も、流体が棒状体の周囲から棒状体の遠心方向に向かって順次浸透して行くので、混合を短時間で行える。 Thus, when drying and sterilizing the material to be processed, the rod-shaped body projecting in the centrifugal direction of the shaft so as to correspond to the amount of the material to be dried around the rotating shaft extends in the axial direction of the horizontal axis. By spraying high-temperature steam, the material to be dried is dried and sterilized sequentially from the periphery of the rod-shaped body toward the centrifugal direction of the rod-shaped body by this high-temperature steam. Can do.
In addition, when a fluid such as liquid or powder is ejected from a rod-like body disposed around the rotating shaft to mix the material to be treated and the fluid such as liquid or powder while stirring, Since the fluid sequentially permeates from the periphery of the rod-shaped body toward the centrifugal direction of the rod-shaped body, mixing can be performed in a short time.

そして、回転軸の周囲に棒状体の配置周期に対応するよう螺旋状の羽根を配設する場合もあり、この場合は、羽根によって容器内が回転軸の軸方向に対し複数の小スペース区に区切られるので、被処理物となる被乾燥物を乾燥また殺菌する場合は、棒状体から回転軸の軸方向に噴射している高温蒸気をこの小スペース区内に留め置くことができ、さらには、回転軸内を通過する高温蒸気により羽根が加熱されるためこの羽根の近傍における高温蒸気の温度低下を小にできて、被乾燥物の乾燥また殺菌を効率よく、かつ充分に行うことができる。
また、回転軸の周囲に配設した棒状体から液体や粉体等の流体を噴射して被処理物となる被攪拌物と液体や粉体等の流体とを混合する場合も、流体を小スペース区内に留め置くことができるので、混合を効率よく行える。 In some cases, spiral blades may be arranged around the rotation axis so as to correspond to the arrangement period of the rod-shaped body. In this case, the inside of the container is divided into a plurality of small space sections with respect to the axial direction of the rotation shaft by the blades. Because it is divided, when drying or sterilizing the material to be treated, high-temperature steam sprayed from the rod-shaped body in the axial direction of the rotating shaft can be kept in this small space area, Since the blade is heated by the high-temperature steam passing through the rotating shaft, the temperature drop of the high-temperature steam in the vicinity of the blade can be reduced, and the drying or sterilization of the object to be dried can be performed efficiently and sufficiently. .
In addition, when fluid such as liquid or powder is ejected from a rod-shaped body disposed around the rotating shaft to mix the object to be treated and the fluid such as liquid or powder, the fluid is reduced. Since it can be kept in the space, mixing can be performed efficiently.

さらに回転軸を回動させて、羽根で被処理物となる被乾燥物を左右方向に往復移動させれば、小スペース区内の被乾燥物をこの小スペース区内においてよく攪拌できて、被乾燥物の乾燥また殺菌を大に効率よく、かつ充分に行える。
また、被処理物となる被攪拌物と液体や粉体等の流体とを混合する場合も、小スペース区内の被攪拌物をこの小スペース区内においてよく攪拌できるので、混合を大に効率よく行える。 Further, if the rotating shaft is rotated and the object to be processed is reciprocated in the left-right direction with the blades, the object to be dried in the small space can be well stirred in the small space, Drying and sterilization of the dried product can be performed very efficiently and sufficiently.
In addition, when mixing the object to be processed and a fluid such as liquid or powder, the object to be stirred in the small space section can be well stirred in the small space section. Well done.

また回転軸を一方回転させて、羽根で被処理物となる被乾燥物や被攪拌物を一方向に移動させながら被乾燥物の乾燥や殺菌、また被攪拌物と流体とを混合すれば、攪拌容器における一方の端部に投入した被処理物が、攪拌容器内を移動して攪拌容器における他方の端部に到達するまでの間に乾燥や殺菌、また混合を終えることができ、さらに攪拌容器における他方の端部に排出口を設けることで、同排出口から乾燥や殺菌、また混合が終了した被処理物を順次取り出せる。   Also, if the rotating shaft is rotated in one direction and the object to be treated and the object to be treated are moved in one direction with the blade, the object to be dried and sterilized, and the object to be stirred and the fluid are mixed, The object to be treated put into one end of the stirring vessel can finish drying, sterilization, and mixing until it moves through the stirring vessel and reaches the other end of the stirring vessel. By providing a discharge port at the other end of the container, it is possible to sequentially take out the objects to be processed after drying, sterilization, and mixing from the discharge port.

以下、本発明の攪拌装置を添付図面に基づいて説明する。
本攪拌装置は、被処理物となる被乾燥物や被攪拌物を収容するための上部が開口（開口１ａ）している攪拌容器１と、この攪拌容器１の攪拌室２に配設した被処理物となる被乾燥物や被攪拌物を攪拌するための棒状体たる攪拌棒３と羽根４を有する回転軸５と、この回転軸５を回転もしくは所望により回動させるためのモータ７を備えている（モータ７の電気配線は省略）。 Hereinafter, the stirring device of the present invention will be described with reference to the accompanying drawings.
The stirring apparatus includes a stirring container 1 having an opening (opening 1a) for storing an object to be dried and an object to be processed, and an object disposed in the stirring chamber 2 of the stirring container 1. There is provided a rotating shaft 5 having a stirring rod 3 and a blade 4 as a rod-shaped body for stirring a material to be dried and a material to be processed, and a motor 7 for rotating or rotating the rotating shaft 5 as desired. (Electric wiring of the motor 7 is omitted).

この攪拌容器１は、図４に示すように、底部が内側に湾曲していて（湾曲底部１ｂ）、また攪拌室２に配設する回転軸５は、攪拌容器１の攪拌室２における底部内面の湾曲方向に対し直交させて配置している。   As shown in FIG. 4, the stirring vessel 1 has a bottom portion curved inward (curved bottom portion 1 b), and the rotating shaft 5 disposed in the stirring chamber 2 is an inner surface of the bottom portion of the stirring chamber 2 in the stirring chamber 2. It is arranged so as to be orthogonal to the bending direction.

また回転軸５は、この回転軸５が回転した際に、回転軸５に有する攪拌棒３および羽根４の先端と攪拌室２の湾曲する底部内面との間に小なる隙間を有して攪拌棒３および羽根４が回転できるように配設している。   Further, when the rotating shaft 5 rotates, the rotating shaft 5 is stirred with a small gap between the tip of the stirring rod 3 and the blade 4 of the rotating shaft 5 and the curved bottom inner surface of the stirring chamber 2. It arrange | positions so that the stick | rod 3 and the blade | wing 4 can rotate.

そして攪拌棒３には、回転軸５の接続口５ａを介して外部から供給される被処理物となる被乾燥物の乾燥また殺菌を行うための高温蒸気や空気等の乾燥用流体、また、被処理物となる被攪拌物と混合する液体や粉体等の流体を、回転軸５の軸方向に略平行に噴射するための噴射口３ａを適数設けている。
なお、上記乾燥用流体を供給する場合には、本実施例の攪拌装置は乾燥装置として利用される。 And in the stirring rod 3, a drying fluid such as high-temperature steam or air for drying or sterilizing an object to be processed supplied from the outside through the connection port 5a of the rotating shaft 5, An appropriate number of injection ports 3a are provided for injecting fluid such as liquid or powder to be mixed with the object to be processed, which is to be processed, substantially parallel to the axial direction of the rotary shaft 5.
In addition, when supplying the said fluid for drying, the stirring apparatus of a present Example is utilized as a drying apparatus.

前述する被処理物たる被乾燥物、例えば茸栽培に用いる植栽土壌（培基）の乾燥や殺菌を行う場合は、摂氏１００度以上に調整した高温蒸気を用いて行うのが普通であるが、被乾燥物の種類によっては摂氏１００度以下の空気や冷却した低温の乾燥空気を用いる場合もある。   When drying or sterilizing the above-mentioned dried material to be treated, for example, planting soil (culture medium) used for straw cultivation, it is common to use high-temperature steam adjusted to 100 degrees Celsius or higher. Depending on the type of object to be dried, air of 100 degrees Celsius or less or cooled low temperature dry air may be used.

前述する被処理物たる被攪拌物が、例えば流体を混合する被攪拌物が茸栽培に用いる植栽土壌（培基）であれば、混合する液体や粉体等の流体は、液状の肥料や粉末あるいは顆粒状の肥料を含む空気であったり、また、植栽土壌（培基）の水分量を調整するための水であったりする。勿論、被乾燥物の種類によって被処理物たる被攪拌物に混合する流体も各種のものがある。   For example, if the agitated material to be treated is a planting soil (medium) used for straw cultivation, for example, the agitated material to be mixed with fluid is a liquid fertilizer or a liquid such as a liquid to be mixed. It may be air containing powder or granular fertilizer, or water for adjusting the water content of planting soil (culture medium). Of course, there are various types of fluids to be mixed with the object to be stirred, which is the object to be processed, depending on the type of object to be dried.

そして攪拌棒３は、回転軸の軸方向に等間隔で設けていて、実施例に示す各攪拌棒３は、９０度ずらしながら螺旋状に軸の周囲に配置しているが、例えば、３０度、４５度、６０度等の角度ずらしながら螺旋状に軸の周囲に配置する場合もある。   The stirring rods 3 are provided at equal intervals in the axial direction of the rotating shaft, and each stirring rod 3 shown in the embodiment is arranged around the shaft in a spiral manner while being shifted by 90 degrees, for example, 30 degrees , 45 degrees, 60 degrees, etc. may be arranged around the axis in a spiral manner while shifting the angle.

また噴射口３ａは、外部の供給装置（図示は省略）から供給される高温蒸気等の乾燥用流体、液体や粉体等の混合に用いる流体の供給圧力に対応する開口にしているが、これら流体の噴射範囲をより拡大するための噴射ノズル（図示は省略）を設ける場合もある。   The injection port 3a has openings corresponding to the supply pressure of a drying fluid such as high-temperature steam supplied from an external supply device (not shown) or a fluid used for mixing liquid or powder. There may be a case where an injection nozzle (not shown) for expanding the fluid injection range is provided.

さらには、噴射口３ａ、噴射ノズル（図示は省略）に、被処理物となる被乾燥物や被攪拌物の進入を確実に防止するためのオリフィス（図示は省略）を設ける場合もある。   Furthermore, an orifice (not shown) may be provided in the injection port 3a and the injection nozzle (not shown) for reliably preventing the material to be processed and the material to be stirred from entering.

前記攪拌棒３は、断面が円形の柱状に形成しているものであるが、略クランク状や略Ｓ字状等のいわゆるかぎの手状に構成して被処理物の攪拌範囲を拡大したり、攪拌効率を向上せしめるようにする場合もある。   The stirring bar 3 is formed in a columnar shape with a circular cross section, but it is configured in a so-called key hand shape such as a substantially crank shape or a substantially S shape, thereby expanding the stirring range of the object to be processed. In some cases, the stirring efficiency may be improved.

そして、外部から供給される高温蒸気等の乾燥用流体、液体や粉体等の混合に用いる流体は、回転軸５の接続口５ａを介し、図４に示すように、回転軸５の内部に形成している接続口５ａに接続する導通路５ｂから攪拌棒３の内部に形成している回転軸５の導通路５ｂに接続している導通路３ｂを通過して噴射口３ａから噴出している。   Then, a drying fluid such as high-temperature steam supplied from the outside, or a fluid used for mixing liquid or powder, etc., enters the inside of the rotating shaft 5 through the connection port 5a of the rotating shaft 5 as shown in FIG. It passes through the conduction path 3b connected to the conduction path 5b of the rotating shaft 5 formed inside the stirring rod 3 from the conduction path 5b connected to the formed connection port 5a, and is ejected from the injection port 3a. Yes.

羽根４は、螺旋状（オーガ状）にしてあって、かつ回転軸５の周囲に攪拌棒３の配置周期に対応するよう配設していて、被処理物となる被乾燥物を乾燥また殺菌する場合は、図３に示すように、攪拌棒３の噴射口３ａから回転軸５の軸方向に略平行に噴射される高温蒸気１０を、回転軸５の軸方向に対し前後の羽根４で挟まれた小スペース区１１に留めることができるようにしている。   The blade 4 has a spiral shape (auger shape) and is arranged around the rotating shaft 5 so as to correspond to the arrangement period of the stirring rod 3 to dry or sterilize the to-be-processed object. 3, the high-temperature steam 10 injected substantially in parallel to the axial direction of the rotating shaft 5 from the injection port 3a of the stirring rod 3 is provided by the front and rear blades 4 with respect to the axial direction of the rotating shaft 5 as shown in FIG. It is possible to keep it in the small space 11 that is sandwiched.

これにより、攪拌棒３から噴射口３ａされた高温蒸気１０は、前後の羽根４で挟まれた小スペース区１１に留められ、さらに羽根４が、図４に示すように、回転軸５内の導通路５ｂを通過する高温蒸気１０によって加熱されるため、この羽根４から放出される熱によって羽根４の近傍に到達した高温蒸気１０の温度低下を小にできて、被乾燥物の乾燥や殺菌を非常に効率よく、かつ充分に行うことができる。   As a result, the high-temperature steam 10 injected from the stirring bar 3 through the injection port 3a is held in the small space section 11 sandwiched between the front and rear blades 4, and the blades 4 are disposed in the rotary shaft 5 as shown in FIG. Since it is heated by the high-temperature steam 10 that passes through the conduction path 5b, the temperature drop of the high-temperature steam 10 that has reached the vicinity of the blade 4 can be reduced by the heat released from the blade 4, and drying and sterilization of the object to be dried Can be performed very efficiently and sufficiently.

そして、攪拌棒３の噴射口３ａから液体や粉体等の流体を噴射して被処理物となる被攪拌物と液体や粉体等の流体（図示は省略）とを混合する場合も、流体（図示は省略）を小スペース区内に留め置くことができるので、混合を効率よく行える。   In addition, when a fluid such as liquid or powder is ejected from the ejection port 3a of the stirring rod 3 to mix a material to be treated and a fluid such as liquid or powder (not shown), the fluid (The illustration is omitted) can be kept in the small space section, so that the mixing can be performed efficiently.
