Description

本発明は、食品残渣処理などに広く利用できる固液分離装置に関するものである。 The present invention relates to a solid-liquid separation apparatus that can be widely used for food residue treatment and the like.

レストランなどから大量に排出される残飯・野菜クズ・生魚アラ・オカラなどの食品残渣は、これまで、埋めたて廃棄や焼却などによって処理されていた。しかしながら、このような方法は、コストやスペースの問題を有するのみならず、環境への負荷の点からも問題であることから、新たな方法として、食品残渣を構成する固形分と水分や油分とを固液分離し、水分や油分の含量を減らした固形分を肥料や飼料の原料として用いる方法が提案され、既に実用化されている。食品残渣をこのようにして処理する際に用いる固液分離装置としては、例えば、下記の特許文献１に記載されたようなものが既に知られているが、常により効率的に処理を行うことができる装置が追求されている。
特開平７−３３０４７６号公報 In the past, food residues such as leftovers, vegetable scraps, raw fish ara, and okara discharged in large quantities from restaurants have been disposed of by disposal or incineration. However, such a method not only has a problem of cost and space, but also has a problem from the viewpoint of environmental load. Therefore, as a new method, a solid content, a moisture content and an oil content constituting a food residue Has been proposed and used in practice as a raw material for fertilizers and feeds. As a solid-liquid separation apparatus used when processing food residues in this way, for example, the one described in the following Patent Document 1 is already known, but always performs processing more efficiently. Devices that can do this are being pursued.

本発明によれば、食品残渣処理などに広く利用できる新規な固液分離装置を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, the novel solid-liquid separation apparatus which can be utilized widely for food residue processing etc. can be provided.

以下、本発明の固液分離装置を、食品残渣処理に用いる場合を例にとって、図面を参照しながら説明するが、本発明は以下の記載に何ら限定して解釈されるものではない。 Hereinafter, the case where the solid-liquid separation device of the present invention is used for food residue treatment will be described with reference to the drawings, but the present invention is not construed as being limited to the following description.

図１は、本発明の固液分離装置の一実施の形態の概略構成図である。固液分離装置１は、内径が前端に向かうに従って漸次小径に形成された円筒形のケーシング２内に、液体成分を含む処理物を前端に搬送するためのスクリューコンベア３を備える略水平方向に設けられた第１手段と、第１手段のケーシング２の前端から適宜後方の上部にその前端で接続された、前端を下方傾斜させたケーシング４内にスクリューコンベア５を備え、処理物を前端に搬送して第１手段のケーシング２内に送り込むための第２手段と、第２手段のケーシング４の上部に接続されたホッパーからなる処理物投入部６を有する。食品残渣は、処理物投入部６から装置内に投入され、第２手段のスクリューコンベア５によってケーシング４の前端に搬送され、第１手段のケーシング２内に送り込まれる。第１手段のケーシング２内に送り込まれた食品残渣は、スクリューコンベア３によってケーシング２の前端に搬送される。第１手段のケーシング２は、略水平方向に設けられ、内径が前端に向かうに従って漸次小径に形成されているので、徐々に圧縮される食品残渣から水分や油分が搾取される。搾取された液体成分は、ケーシング２の後端に向かって形成された下方傾斜を利用して捕集され、ガイド７を伝って容器８に貯留される（少なくともガイド７の上部に位置するケーシング２の底部は網状部材９で構成しておく）。一方、液体成分が分離された後の固形分は、ケーシング２の前端に、閉止用蓋１０が所定の圧力で押圧されるまで押し込まれた後、閉止用蓋１０が開かれて外部に排出され、ガイド１１を伝って容器１２に貯留される。本発明の固液分離装置によれば、食品残渣を構成する固形分と水分や油分とを効率よく分離することができるので、食品残渣から肥料や飼料の原料となる固形分の取得が容易になる。 FIG. 1 is a schematic configuration diagram of an embodiment of a solid-liquid separation device of the present invention. The solid-liquid separation device 1 is provided in a substantially horizontal direction provided with a screw conveyor 3 for transporting a processed product containing a liquid component to a front end in a cylindrical casing 2 formed with a gradually decreasing inner diameter toward the front end. And a screw conveyor 5 in a casing 4 which is connected to the front end of the first means from the front end of the casing 2 to the rear upper part of the first means, and the front end is inclined downward, and conveys the processed material to the front end. The second means for feeding into the casing 2 of the first means, and the workpiece input portion 6 comprising a hopper connected to the upper part of the casing 4 of the second means. The food residue is fed into the apparatus from the processed material throwing section 6, conveyed to the front end of the casing 4 by the screw conveyor 5 of the second means, and fed into the casing 2 of the first means. The food residue fed into the casing 2 of the first means is conveyed to the front end of the casing 2 by the screw conveyor 3. The casing 2 of the first means is provided in a substantially horizontal direction and has an inner diameter that gradually decreases toward the front end, so that moisture and oil are extracted from the food residue that is gradually compressed. The squeezed liquid component is collected by using a downward inclination formed toward the rear end of the casing 2 and is stored in the container 8 through the guide 7 (at least the casing 2 positioned above the guide 7). The bottom portion is made up of a mesh member 9). On the other hand, the solid content after the liquid component is separated is pushed into the front end of the casing 2 until the closing lid 10 is pressed at a predetermined pressure, and then the closing lid 10 is opened and discharged to the outside. Then, it is stored in the container 12 through the guide 11.
