Description

本発明は、魚類、食品などの残渣廃棄物の活用技術に関し、魚の粗(あら)、魚腸骨、厨芥残渣等(以下、食品残渣と称す)に焙煎した添加物を混合して予備処理し、成型、乾燥などの段階を経て養殖魚類飼料、家畜飼料などを得る食品残渣の処理方法及び処理装置に関するものである。   The present invention relates to a technology for utilizing waste waste from fish, foods, etc., and pre-treatment by mixing roasted additives with coarse fish, fish iliac bones, salmon residues (hereinafter referred to as food residues), etc. In addition, the present invention relates to a food residue processing method and a processing apparatus for obtaining cultured fish feed, livestock feed and the like through stages such as molding and drying.

市民生活において食生活の位置づけは益々嗜好が高度化、多様化の方向を辿り、食品残渣の処理が良好な環境維持、資源の再利用、廃棄処理経費の圧縮などの観点から重要な社会関心事となってきた。最近では2001年4月に施行された食品リサイクル法の実施も加味して、食品製造及び消費過程で発生する食品残渣の量を抑制するとともに飼料や肥料等に再利用する合理的なシステムの開発が求められる状況となってきた。   The positioning of eating habits in civic life is becoming an increasingly important social concern from the perspectives of increasing sophistication and diversification, maintaining a good environment for processing food residues, reusing resources, and reducing disposal costs. It has become. In recent years, taking into account the implementation of the Food Recycling Law, which took effect in April 2001, the development of a rational system for reducing the amount of food residues generated during the production and consumption of food and reusing it for feed, fertilizer, etc. Has come to be required.

欧米では、相当以前から小型魚類の飼料、肥料などへの活用が体系的に進められ、魚介類などの食品残渣のリサイクルが行われてきたが、処理に伴う残余廃棄物の発生や食品残渣の腐敗に伴う悪臭公害の発生、取り扱い性などの問題が提起され課題となっていた。   In Europe and the United States, the use of small fish for feed, fertilizer, etc. has been systematically promoted for a long time, and food residues such as seafood have been recycled. Problems such as the occurrence of foul odor pollution caused by corruption and handling were raised.

この傾向は、本邦においても今後食品リサイクル法が徹底され、リサイクル率が向上するに伴って加速される問題であり、食品残渣の体系的、合理的な処理方法及び処理装置の確立が求められている。従来は埋め立て廃棄、焼却等によって処理されていたが、処理コストや処理スペースの問題、更には環境への負荷増等の点からも大きな社会問題が生じており、これに代わる各種解決方法が検討されてきた。食品残渣の処理方法の一例として、これをそのまま家畜等の飼料として利用することも広く行われている。しかしながら、残渣の形態のままでは多量の水分を含み、形態や臭い等の問題があり、保存、流通、保管にも不適であることから、飼料や肥料として再利用が図られてきたが、量的な限度があるのが現状である。   This trend is a problem that will be accelerated as food recycling laws are thoroughly enforced in Japan and the recycling rate is improved in the future, and the establishment of systematic and rational processing methods and processing equipment for food residues is required. Yes. Conventionally, it has been disposed of by landfill disposal, incineration, etc., but there are significant social problems in terms of processing costs and processing space, as well as an increase in environmental burden, and various alternative solutions are being considered. It has been. As an example of a method for treating food residues, it is also widely used as it is as feed for livestock and the like. However, the residue form contains a large amount of water, has problems such as form and odor, and is unsuitable for storage, distribution, and storage, so it has been reused as feed and fertilizer. There are current limitations.

一方、上記の問題点を解決すべく、食品残渣を発酵や乾燥させ、必要に応じて流通に適するような形態に飼料化することも提案されている。例えば、特開2002−335781号公報によれば、食品残渣と食品残渣の含水率を調節するための副資材及び発酵菌を混合して発酵槽内で混合物の温度が70〜80℃で、13〜20時間発酵、熟成した後、乾燥・粉砕して粉状飼料とする方法が開示されている。
特開2002−335781号公報(第5〜7頁、第1図)
On the other hand, in order to solve the above-mentioned problems, it has been proposed to ferment or dry food residues and convert them into a form suitable for distribution if necessary. For example, according to Japanese Patent Application Laid-Open No. 2002-335781, a food residue and a secondary material for adjusting the moisture content of the food residue and a fermenting bacterium are mixed, and the temperature of the mixture is 70 to 80 ° C. in the fermenter. A method is disclosed in which after -20 hours of fermentation and ripening, the powdered feed is dried and ground.
Japanese Patent Laid-Open No. 2002-335781 (pages 5-7, FIG. 1)

この方法は、家畜に対する嗜好性を富化した高品質の飼料を得る点では評価できるが、この方法を実施するには、装置が複雑で、多種類の機器を必要とし、また、処理も複雑で、かつ、長い発酵処理時間を要し、また、得られる飼料も粉状であることで取り扱い上注意を要するなど不具合な点もある。これに対し本発明は、魚の粗(あら)、魚腸骨、厨芥残渣等の食品残渣から取り扱い容易なペレット状飼料を得ることを目的としたものであって、魚の粗(あら)等の装置壁面への粘着・付着による問題、即ち、食品残渣の長時間に亘る装置壁面への粘着・付着は装置内腐敗や付着成長による詰りのトラブルの発生、また、外熱式乾燥装置では熱伝達の阻害や過熱・焦げの発生による異臭発生等のこれら問題を解消することを重点にした、単純で、処理時間も長時間を要しない食品残渣の処理方法を、また、複雑でなく、コンパクトで設備コストも合理的で、省エネルギ型である処理装置を提供するものである。   Although this method can be evaluated in terms of obtaining a high-quality feed enriched with palatability for livestock, the implementation of this method requires complex equipment, requires many types of equipment, and processing is also complicated. In addition, it takes a long fermentation treatment time, and the feed obtained is also in the form of powder, so that there are problems such as requiring care in handling. On the other hand, the present invention aims to obtain a pellet-shaped feed that is easy to handle from food residues such as fish coarse, fish iliac, and salmon residue, and is a device for rough fish. Problems due to adhesion / adhesion to the wall surface, that is, sticking / adhesion of food residues to the apparatus wall for a long time may cause clogging troubles due to internal rot or adhesion growth, and heat transfer with an external heating dryer A simple and compact, non-complex and compact facility that focuses on solving these problems such as obstruction, overheating, and the generation of a strange odor due to the occurrence of scorching. The present invention provides a processing apparatus that is reasonable in cost and energy saving.

図1のフロシートに基づいて食品残渣1の処理について説明すると、集荷された食品残渣1は粗選別機2によって夾雑物を除いた後、水分が多い(水分80%以上)場合、必要に応じて調湿機3で一般に過剰の水分を除き、破砕混合機4へ送られる。一方、食品残渣に対して重量比10〜150%の範囲の混合比率で切出された植物性飼料添加物9は、焙煎機11に送られ、焙煎機11内で電熱又は燃焼ガスから成る熱源に間接的に接触して、かつ、混合攪拌されることにより均一に昇温して焙煎される。焙煎のための滞留時間は1〜30分の範囲であって、通常10分程度になるよう加熱条件を設定する。植物性飼料添加物9は最終的に飼料となり、かつ、食品残渣1の表面に付着し易く、焙煎しても性状を損なわず、焦げも発生しないものが適宜選択され、これらにはぬか、粉状の大豆粕、ふすまのいずれか又はその混合物が該当する。前記の性状と性質を有する植物性添加物であれば、この添加物として採用可能である。   The processing of the food residue 1 will be described based on the flow sheet of FIG. 1. The collected food residue 1 is free from impurities after being removed by the coarse sorter 2, and if necessary, if the water content is high (water content of 80% or more). In general, excess moisture is removed by the humidity controller 3, which is then sent to the crushing mixer 4. On the other hand, the vegetable feed additive 9 cut out at a mixing ratio in the range of 10 to 150% by weight with respect to the food residue is sent to the roasting machine 11, and from electric heat or combustion gas in the roasting machine 11. Indirect contact with the heat source and the mixture is stirred and mixed to raise the temperature uniformly and roast. The residence time for roasting is in the range of 1 to 30 minutes, and the heating conditions are usually set to about 10 minutes. The vegetable feed additive 9 is finally selected as a feed, and is easily selected to adhere to the surface of the food residue 1 and does not lose its properties even when roasted and does not cause burns. Either powdery soybean meal, bran or a mixture thereof is applicable. Any plant additive having the above properties and properties can be used as this additive.

破砕・混合機4では、装入された食品残渣1がパドル軸に付設された破砕刃群により繰り返し切断・破砕を受け細片となる。一方、焙煎された温度80〜150℃を有する植物性飼料添加物9は、破砕・混合機4の前部分、すなわち食品残渣1が繰り返し切断・破砕を受ける場所に進行方向に幅広く装入される。次いで食品残渣1と植物性飼料添加物9との混合物は後方のパドルに付設された混合攪拌羽根により十分混合攪拌される。これにより温度の高い粉状の植物性飼料添加物9が、細断された食品残渣1の表面に満遍なく一様に付着することによって食品残渣1の表面水分を一部蒸発させた上で水分を吸着するので、食品残渣と植物性飼料添加物との混合物である予備処理原料11の粘着・付着性が失われ、後工程において機器壁面への混合物の粘着、付着が僅少になる。また、成型工程で成型し易い性状(水分、粘結性、サイズ等)に予備処理される。さらに、悪臭の発生源となる食品残渣1が表面を植物性飼料添加物9で被覆されるから、直接悪臭が外気に放出されるのを抑制し、次の成型と相俟って外部の環境(外部の細菌、温度等)の影響を受けるのが少ないから、腐敗し難くなり悪臭の発生も防止できる。   In the crushing / mixing machine 4, the charged food residue 1 is repeatedly cut and crushed into pieces by a crushing blade group attached to the paddle shaft. On the other hand, the roasted vegetable feed additive 9 having a temperature of 80 to 150 ° C. is widely charged in the traveling direction in the front part of the crushing / mixing machine 4, that is, the place where the food residue 1 is repeatedly cut and crushed. The Next, the mixture of the food residue 1 and the vegetable feed additive 9 is sufficiently mixed and stirred by a mixing stirring blade attached to the rear paddle. As a result, the powdery vegetable feed additive 9 having a high temperature adheres evenly and uniformly to the surface of the shredded food residue 1 to partially evaporate the surface moisture of the food residue 1 and then the moisture. Since it adsorbs, the adhesion / adhesion of the pretreatment raw material 11 which is a mixture of the food residue and the plant feed additive is lost, and the adhesion and adhesion of the mixture to the apparatus wall surface become small in the subsequent process. Further, it is preliminarily processed into properties (moisture, caking property, size, etc.) that are easy to mold in the molding process. Furthermore, since the food residue 1 that is a source of malodor is coated with the plant feed additive 9 on the surface, it prevents direct malodor from being released to the outside air, and in combination with the next molding, the external environment Since it is less affected by (external bacteria, temperature, etc.), it is difficult to rot and the generation of malodor can be prevented.

破砕・混合機4からの予備処理された混合物11は成型機5の装入ホッパにベルトコンベアで送られる。装入ホッパから定量切出された混合原料11は成型機内のニーダにより混練されながら圧密され、成型サイズの孔の開いたダイスから押出し成型される。成型ペレット12は通常、径が5〜10mm、長さが5〜10mmの範囲であって、最終飼料製品のサイズから乾燥・混和器6での乾燥目減りを見込んで成型ペレット12のサイズが設定される。この方式では成型ペレット12のサイズが大きいほど成型は容易であるが、乾燥・混和器6,30では乾燥及び混和がし難い。   The pre-processed mixture 11 from the crushing / mixing machine 4 is sent to a charging hopper of the molding machine 5 by a belt conveyor. The mixed raw material 11 quantitatively cut out from the charging hopper is compacted while being kneaded by a kneader in the molding machine, and extruded from a die having a hole of a molding size. The molded pellets 12 are usually in the range of 5 to 10 mm in diameter and 5 to 10 mm in length, and the size of the molded pellets 12 is set in consideration of the reduction of dryness in the drying / mixer 6 from the size of the final feed product. The In this method, the larger the size of the molded pellet 12, the easier the molding, but the drying / mixing devices 6, 30 are difficult to dry and mix.

成型ペレット12はベルトコンベアにより乾燥・混和器30の上部ペレット装入孔31を経由して装入される。装入された成型ペレット12はペレット分散板35の中央上部に装入され、処理する食品残渣の安息角以上の角度の傘状円錐板上を重力により360°の全方向に拡がりながら滑落し、次いで二段目の逆傘状円錐板の端部に乗り移り、同じく重力により滑落しながらペレット反転板36の中央に寄せ集められ、次いで傘状の熱風分散板37の円錐板上を360°の全方向に拡がりながら滑落し、最終的に乾燥・混和器30の円錐コーンの中央に集まりペレット排出孔32より排出される。成型ペレット12は各段の円錐板上を滑落するときに、円錐板に設けられた熱風通過スリットを吹き上がる乾燥用熱風と滑落しながら向流接触し均一に乾燥される。また、成型ペレットは多少浮遊状態で滑落するから円錐板との付着も起こり難い。また、成型ペレット12は三段階に亘り分配、反転、分散を経るから混和が十分図られる。通常、この滞留時間は15分程度である。乾燥混和器30で、取り扱い性にも着目した水分(湿度)に乾燥し、かつ、混和した製品ペレット14は、所定方法の冷却器7を経て包装機8で包装して、製品14となる。   The molded pellets 12 are charged via the upper pellet charging hole 31 of the drying / mixing device 30 by the belt conveyor. The charged molded pellets 12 are inserted into the center upper part of the pellet dispersion plate 35 and slide down while spreading in all directions of 360 ° by gravity on the umbrella-shaped conical plate having an angle greater than the repose angle of the food residue to be processed. Next, it is transferred to the end of the second-stage inverted umbrella-shaped conical plate, gathered to the center of the pellet reversing plate 36 while also sliding down due to gravity, and then the entire 360 ° of the umbrella-shaped hot air dispersing plate 37 on the conical plate. It slides down while spreading in the direction, and finally gathers at the center of the conical cone of the drying / mixer 30 and is discharged from the pellet discharge hole 32. When the molded pellets 12 slide down on the conical plates of the respective stages, they are counter-contacted while being slid down with the hot air for drying that blows up the hot air passage slits provided in the conical plates and are uniformly dried. Further, since the molded pellet slides down in a slightly floating state, it does not easily adhere to the conical plate. In addition, since the molded pellet 12 undergoes distribution, inversion, and dispersion in three stages, mixing is sufficiently achieved. Usually, this residence time is about 15 minutes. The product pellets 14 that have been dried and mixed with moisture (humidity) that also pays attention to handleability in the dry blender 30 are packaged by the packaging machine 8 through the cooler 7 of a predetermined method to become the product 14.

本システムでは、食品残渣槽、粗選別機2、調湿機3、破砕・混合機4の各機器から発生する環境臭気ガス及び乾燥・混和器から発生する臭気排ガスを所定方法の排ガス燃焼式の脱臭器17に導いて脱臭し、一部を排ガスブロアにより強制的に又は自然ドラフトで大気に排気22として排出する。排気ガスの残部は、循環ブロア15、熱風発生加熱器16での昇温を経て乾燥・混和器30に還流することにより省エネルギが達成できる。   In this system, the environmental odor gas generated from each device of the food residue tank, the coarse sorter 2, the humidity controller 3, and the crushing / mixing device 4 and the odor exhaust gas generated from the drying / mixing device are exhausted by a predetermined method. It leads to the deodorizer 17 for deodorization, and a part thereof is forcibly exhausted by an exhaust gas blower or discharged into the atmosphere as an exhaust 22 by natural draft. The remainder of the exhaust gas is heated by the circulation blower 15 and the hot air generator / heater 16 and then returned to the drying / mixer 30 to save energy.

本発明に係る食品残渣の処理方法に基づき、実験装置により飼料を製造した。食品残渣として「はまち」の粗(あら)を、植物性飼料添加物として、ぬか、大豆粕混合物を用いて、粗(あら)約10kg/h、該添加物3kg/で、粗(あら)に対する添加物の混合比約30%の処理条件で実験を実施した。   Based on the food residue treatment method according to the present invention, feed was produced by an experimental apparatus. The crude residue of “hama” as a food residue, bran or soybean meal mixture as a vegetable feed additive, about 10 kg / h of the coarse product, and 3 kg / h of the additive, with respect to the crude product The experiment was carried out under processing conditions with an additive mixing ratio of about 30%.

ぬか、大豆粕混合物を円筒回転型焙煎機に挿入し、外部から間接加熱を行い、混合物を10分加熱して、温度120℃で排出し、破砕刃及び攪拌羽根付の破砕・混合機において魚の粗(あら)と破砕、混合して成型用予備処理材料を得た。ついで、該材料を混錬付加圧押し出し式の成型機により径5mm、長さ5〜8mm、水分50%の円筒型ペレットを成型した。該成型ペレットを内径300mm、高さ1.2mの円筒で、内部がペレット分散板、反転板、熱風分散板の三段から成る乾燥・混和器に装入し、90℃の熱風で、器内滞留時間15分で乾燥・混和を実施した後、外気で空冷し冷却した。得られた製品ペレットの含有水分は約15%であった。   The bran or soybean meal mixture is inserted into a cylindrical rotary roaster, indirectly heated from the outside, heated for 10 minutes, discharged at a temperature of 120 ° C., in a crushing / mixing machine equipped with a crushing blade and stirring blades Preliminary processing material for molding was obtained by crushing and mixing with rough fish. Next, the material was molded into a cylindrical pellet having a diameter of 5 mm, a length of 5 to 8 mm, and a moisture of 50% by a kneading applied pressure extrusion molding machine. The molded pellet is a cylinder with an inner diameter of 300 mm and a height of 1.2 m, and the inside is charged into a drying / mixer consisting of a pellet dispersion plate, a reversal plate, and a hot air dispersion plate. After drying / mixing with a residence time of 15 minutes, it was cooled with air and cooled with the outside air. The moisture content of the obtained product pellets was about 15%.

前記の破砕・混合機出口と乾燥・混和器出口の排ガスを700℃、滞留時間約1秒の再燃焼脱臭方式の脱臭器で脱臭した。また、植物性飼料添加物の有無の場合における破砕・混合機の排気の臭気を分析したところ、添加物無しの従来法では臭気単位21800であるのに対し、本発明の添加物有りの試験では臭気単位8300と減少した。これから本発明に係る添加物有りの場合の脱臭率は62%と認められた。なお、臭気単位の分析は悪臭防止法(平成7年環境庁告示第63号)の「臭気強度」を嗅覚により求める方法によった。   The exhaust gas from the crushing / mixer outlet and the drying / mixer outlet was deodorized with a re-combustion deodorizer of 700 ° C. and a residence time of about 1 second. Further, when the odor of the crushing / mixing machine exhaust in the presence or absence of the plant feed additive was analyzed, the odor unit was 21800 in the conventional method without the additive, but in the test with the additive of the present invention. The odor unit decreased to 8300. From this, it was recognized that the deodorization rate with the additive according to the present invention was 62%. The analysis of odor units was based on the method of obtaining the “odor intensity” of the Odor Control Law (Environmental Agency Notification No. 63 of 1995) by smell.

本実施例によれば、食品残渣の粘着・付着成長による装置内壁面の付着が無く、かつ、取り扱い容易な飼料ペレットが製造できたことで本発明の所期の目的達成を確認した。また、得られた飼料ペレットの貯蔵においても固着成長も腐敗も見られなかった。また。乾燥混和器内壁面への食品残渣混合物の粘着は見られず、順調に稼動することができた。また、食品残渣の処理装置から発生する雰囲気の悪臭は軽微であった。   According to the present example, it was confirmed that the intended purpose of the present invention was achieved by the production of feed pellets that were easy to handle and did not adhere to the inner wall surface of the apparatus due to adhesion and adhesion growth of food residues. Further, neither fixed growth nor rot was observed in the storage of the obtained feed pellets. Also. The food residue mixture did not stick to the inner wall of the dry blender and was able to operate smoothly. Moreover, the bad odor of the atmosphere generated from the food residue treatment apparatus was slight.

食品残渣を廃棄することなく、飼料としてのリサイクル活用に利用できる。   It can be used for recycling as feed without discarding food residues.
