Description

【0001】
【発明の属する技術分野】
本発明は、冷蔵庫等の筐体内に、一体化あるいは別体として装着される食料品の鮮度維持及び制菌・殺菌装置に関するものである。
【0002】
【従来の技術】
私たちが日常、食材として扱う生鮮食料品例えば、ほうれん草、キャベツ、白菜等は、通常冷蔵庫の野菜収納室に収納して保存している。そこで、キャベツや白菜等の比較的大物に分類される野菜や、一般に数本単位で販売されているきゅうり等は、一度の料理では全てを使用できず、大半を冷蔵庫内の野菜収納庫に保存することになる。このようにして、これらの生鮮食料品を数日間冷蔵庫内に保存すると、鮮度が落ち本来の風味や食感を損ねてしまい、最終的には腐食して食材として使用できなくなり、大半を廃棄することになる。
【0003】
また、生鮮食料品の長期保存の方法としては、生鮮食料品を冷凍庫で凍らして保管する方法があるが、料理する際凍結した食材を解凍する時間を要すると共に、食材本来の風味や食感を損ねる場合がある。
【0004】
さらに、生鮮食料品の長期保存を成す従来技術として、例えば特開2001−231507号公報には、鶏卵を65〜90℃の温度で加温すると同時に、鶏卵全体に3〜30μmの波長を有する遠赤外線が満遍なく照射するよう構成された茹で卵様食品の製造装置が開示されている。
【0005】
【発明が解決しようとする課題】
上述したように、生鮮食料品等を冷蔵庫に保存する場合、ある一定期間は新鮮さを保持できるが、その期間を過ぎると、鮮度が落ち本来の風味や食感を損ねることになり、最終的には腐食にまで至ってしまう場合がある。
また、長期保存する場合に、冷凍庫に保管して凍結させる場合があるが、自然解凍する場合には、解凍時間に相当の時間を必要とし、電子レンジ等で解凍する場合には、解凍する際に食材からドリップ等が抽出し本来の風味や食感を損ねる虞がある。
【0006】
さらに、特開2001−231507号公報の茹で卵様食品の製造装置には、鮮度維持作用については遠赤外線放射によると言及しているが、殺菌及び解凍作用については言及されておらず、まだ改善の余地がある。
【0007】
本発明は、かかる点に鑑みてなされたものであり、食料品、特に生鮮食料品の鮮度維持作用、殺菌及び解凍作用の各機能を作用する食料品の鮮度維持及び制菌・殺菌装置を提供することを目的とする。

【0018】
【発明の実施の形態】
以下、本発明の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置を図1〜図7に基いて詳細に説明する。
まず、本発明の第1及び第2の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置について説明する。
本発明の第1の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置1は、図1に示すように、市販の冷蔵庫内の野菜等を収納する野菜収納庫1a(幅450mm、高さ350mm、奥行き400mm)の両側壁面1bに、発熱素材であるヒータ線1cを線間50mmとなるように配線する。次に、この野菜収納庫1aの両側壁面1bに遠赤外線を放射させる物質であるセラミック粉体1e(斑点部)を塗布する。また、ヒータ線1cへの電気の供給は、冷蔵庫の本体電源とは別回路として、供給電圧を24V〜100Vの領域で供給するために変圧器10(スライダック)を使用して、冷蔵庫内の雰囲気温度をプラス5℃前後からプラス40℃に設定する。
また、この野菜収納庫1aの内部の後壁1dの上方には、遠赤外線の放射を表示するため、薄い緑色で発光する照明ランプ11が装着されている。
【0019】
本発明の第2の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置の発熱部材2は、図2に示すように、上壁を開口した四角柱状の箱型に形成された収納庫2aからなり、この収納庫2aの両側壁面2bには発熱体20が着脱可能に取付けられている。この発熱体20は、発熱素材であるニクロム線に遠赤外線を放射させる物質のセラミックを付加させたセラミック加工したニクロム線、またはカーボンフィラメント線20bを線間50mmとなるようにアルミ製板材20aに固定して配線している。このセラミック加工したニクロム線、またはカーボンフィラメント線20bは、セラミック加工したニクロム線、またはカーボンフィラメント線20bを被覆保護するようにエポキシ樹脂系接着材(合成樹脂材)を塗布してアルミ製板材20aに固定されている。
【0020】
このセラミック加工したニクロム線、またはカーボンフィラメント線20bへの電気の供給は、第1の実施の形態と同等で冷蔵庫の本体電源とは別回路として、供給電圧を24V〜100Vの領域で供給するために変圧器10(スライダック)を使用し、冷蔵庫内の雰囲気温度をプラス5℃前後からプラス40℃に設定する。
また、収納庫2a内部の後壁2dの上方には、遠赤外線の放射を表示するために、薄い緑色で発光する照明ランプ11を装着している。
【0021】
本発明の第1及び第2の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置を用いた実験結果、特に鮮度維持作用の実験結果を以下に説明する。
第1の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置である冷蔵庫内の野菜収納庫1aに、ほうれん草、キャベツ、キュウリ、小松菜、白菜、モヤシの生鮮食料品を満杯になるまで入れ、扉を閉めて通電を開始した。
同様に、第2の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置の発熱部材2の収納庫2aにも、同様の生鮮食料品を満杯になるまで入れて、冷蔵庫内の所定位置に収めて、扉を閉めて通電を開始した。
【0022】
そこで、実験の条件を、電圧を50Vとして、冷蔵庫内の温度を8℃に設定し、1日30分の通電を8時間おきに3回実施して15日間試験を実施した。ここで、実験の途中に、1日に6〜7回の割合で冷蔵庫の扉を開閉して、野菜収納庫1a及び収納庫2aに外部からの空気の出し入れを行った。
そして、まず5日間のほんれん草、キャベツ等の鮮度状態の評価を行った。その結果を図3に示す。
【0023】
さらに、同一の条件にて、継続して10日間の試験を実施した。この期間では、キャベツ、白菜は半分に切断して試験を継続した。その結果を図4に示す。
【0024】
図3及び図4に示すように、1日30分3回の割合で遠赤外線を放射した野菜類は、保存期間を10日経過しても、鮮度が維持される結果となった。
一方、遠赤外線を放射せず通常の冷蔵庫の野菜室に保管したほうれん草、白菜及び小松菜等は、6日を経過すると、葉の水分が取られ萎びが生じ鮮度が落ちる状態となる。また、モヤシについては、腐食が進行し袋の内部に腐った汁が見受けられ明らかに腐食が進行している状態となる。
このようにして、遠赤外線を放射した野菜類は、通常の冷蔵庫の野菜収納室で保存された野菜類より約2倍の期間、鮮度を維持することができる。
【0025】
次に、本発明の第3の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置について説明する。
本発明の第3の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置の発熱部材3は、図5に示すように、アクリル樹脂製で形成され、上壁を開口した箱本体3a(幅450mm、高さ60mm、奥行き400mm)の底板3bに、発熱素材のニクロム線に遠赤外線を放射させるセラミックを付加させたセラミック加工したニクロム線、またはカーボンフィラメント線3cを線間30mmとなるように配線している。そして、このセラミック加工したニクロム線、またはカーボンフィラメント線3cを被覆保護するようにエポキシ樹脂系接着材(合成樹脂材)を塗布してステンレス板3dに固定する。このセラミック加工したニクロム線、またはカーボンフィラメント線3cは1回路で定格電圧100V、消費電力50Wとする。
【0026】
本発明の第3の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置を用いた実験結果、特に解凍及び殺菌作用の実験結果を以下に説明する。
まず、第3の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置の発熱部材3を冷蔵庫内の所定位置に取付け、セラミック加工したニクロム線、またはカーボンフィラメント線3cに通電した。すると、発熱部材3の底部3bに配設されたステンレス板3dの上面温度が通電開始から8分で60℃に上昇する。そして、このステンレス板3dの上面に、マイナス15℃で冷凍された各食材、牛肉(約5mm)、マグロの切り身、えび天ぷら、ピザを載せて、箱本体3aを図示しないアクリル樹脂製の蓋で閉塞し、解凍実験を行った。
【0027】
その結果、牛肉は15分後、液汁であるドリップが出ず解凍され、マグロの切り身も同様にドリップが出ず20分で解凍した。さらに、えび天ぷら及びピザは25分で解凍が完了した。
このように冷凍された各食材の解凍実験において、全ての食材にドリップが発生せずに、各食材とステンレス板3dの上面との間の接触面に、水滴や油等が見られず極めて良好に解凍が成された。
【0028】
次に、前記実験と同様の食材を用いて、発熱部材3のステンレス板3dの上面温度を60℃から10℃前後に変更して解凍実験を行った。
この解凍実験では、冷蔵庫の内部温度が約6℃で、発熱部材3の内部温度が10℃となっており、その差4℃における解凍時間と解凍状態について検証を試みた。
その結果、各食材には全くドリップが発生せず、良好な状態で約3時間で全ての食材が解凍された。また、解凍が終了した後も連続5時間通電したままの状態でも、各食材の劣化やドリップの発生は確認されなかった。
【0029】
次に、本発明の第3の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置の殺菌実験では、発熱部材3であるステレンス板3dの上面に各食材を載せて、このステンレス板3dの上面温度を40℃〜55℃に設定し連続5時間の加熱した。その後、各食材の一般生菌、大腸菌、黄色ブドウ菌、サルモネラ菌、O−157菌の菌検査を実施したが、全て陰性で良好な結果となった。
【0030】
次に、本発明の第4及び第5の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置について説明する。
本発明の第4の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置の発熱部材4は、図6に示すように、略矩形状の板状であって、板厚1mmのアルミ板が1m当り40W発熱するニクロム線、またはカーボンフィラメント線4aを、線間20mmとなるように板厚1mmのアルミ板4bの片面に配線した。次に、アルミ板4bの両面から遠赤外線を放射させるセラミック粉体4c(斑点部)を塗布し全厚さを3mmとして、表面を絶縁処理した。
【0031】
本発明の第5の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置の発熱部材5は、図7に示すように、略矩形状の板状であって、板厚3mmのFRP製板が0.5m当り100W発熱する銅粉5bを、遠赤外線を放射させるFRP製板5aの片面に、厚さが1mm程度となるように塗布(細かい斑点部)した。次に、これら銅紛5b及びFRP製板5aを被覆保護するように、エポキシ樹脂系接着材(合成樹脂材)を銅紛5bの表面及びFRP製板5aの表面にそれぞれ塗布して、厚み2mmのFRP製板5cを接着しサンドイッチ構造にして絶縁処理した。電極5dは、両面に塗布された銅粉5bの一端部に、銀ペーストを塗り、その上に銅テープを貼り電極化した。
【0032】
本発明の第4及び第5の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置を用いた実験結果、特に鮮度維持及び解凍作用の実験結果を以下に説明する。まず、第4及び第5の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置の発熱部材4及び5のそれぞれを、別々の冷蔵庫の野菜収納庫に装着して、生鮮食料品の野菜類を野菜収納庫に収納した。
そして、野菜収納庫内の温度が5℃〜6℃の温度領域になるように通電を行い、第1及び第2の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置を実験した条件と同様の条件で、野菜類に遠赤外線の放射を行った。
その結果、これら第4及び第5の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置の発熱部材4及び5の両者ともに、第1及び第2の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置の実験結果とほぼ同等の結果となり、鮮度維持の作用効果が確認された。
【0033】
次に、第4及び第5の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置の発熱部材4及び5のそれぞれの表面温度を80℃にして、マイナス25℃で冷凍された冷凍弁当を載せ、解凍実験を行った。
その結果、第4の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置については、発熱部材4の表面温度が高温であったため、若干ドリップが発生し、冷凍弁当の容器の底が変形した。
また、第5の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置についても、ドリップが発生して、さらに発熱部材5と当接している冷凍弁当の表面は、温度が高く解凍が早いが、内部の温度が低いため、表面と内部の温度の均一性について問題を生じた。
【0034】
このように、本発明の第1〜第5の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置によると、第1〜第5の実施の各形態ごとに、鮮度維持、殺菌及び解凍の各機能のいずれかを選択的に達成することができる。したがって、各機能に応じた形態を、例えば冷蔵庫の同一筐体内に複数配設し、同時に動作させることができる。また、冷蔵庫の筐体内に単一の発熱部材を配設して、遠赤外線の加熱保温温度を各機能に応じて変化させることにより、鮮度維持、殺菌または解凍の各機能を選択することもできる。
【0035】
次に、前記した本発明の第1〜第5の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置の応用例について説明する。
本発明の第1〜第5の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置は、各家庭にある冷蔵庫、食料品量販店の食品陳列ケース及び食材の運搬を行う例えば大型自動車等の食品保存庫に、一体化して配設することができる。
【0036】
本発明の第2〜第5の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置の発熱部材は、各家庭にある冷蔵庫の筐体内、及び食料品量販店等で食料品を陳列している陳列ケースの筐体内を区画する底壁、側壁または上壁等に着脱自在に装着することができる。また、この発熱部材を、多くの食料品を保存保管する保存保管室内で、例えば食料品を食材ごとに区分けしているラック等にも着脱自在に装着することができる。
【0037】
また、発熱部材を冷蔵庫や陳列ケースの筐体内を複数に区画する仕切り板として配設して、それぞれの発熱部材をカプラ等で着脱自在に連結して、それぞれの発熱部材へ同一電源から電気を供給する。
そして、このように複数の発熱部材により区画された空間を、保温、解凍、殺菌、鮮度維持の各機能ごとに、保温スペース、解凍スペース、殺菌スペース、鮮度維持スペースとして形成することができる。
【0038】
さらに、移動型の食料品量販店で屋外に食材を陳列する陳列ケースの内部及び、食材の運搬を行う例えば食品保存庫を有する大型自動車等にも、この発熱部材を装着することができる。
【0039】
以上、本発明の第1〜5の実施の形態に係る食料品の鮮度維持及び制菌・殺菌装置を説明したが、さらに、発熱部材は、遠赤外線を放射させるポリアクリルニトリル系炭素繊維と、金、銀、銅、ニッケル、その他の超極細金属系からなる発熱素材とを、ガラス繊維または耐熱繊維素材により交互に織るか、あるいは編組状に編み込んだ板状または線状からなる構造にも形成することができる。
【0040】
【発明の効果】

【0042】
請求項6及至8に記載した発明によれば、発熱部材を複数形成して、それぞれの発熱部材をカプラ等を介して着脱自在に連結することができるので、生鮮食料品が保存され得る場所に、機能別に各発熱部材を装着することができ実用上有利である。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an apparatus for maintaining freshness of a food product and controlling or sterilizing / sterilizing the food product, which is integrally or separately mounted in a housing of a refrigerator or the like.
[0002]
[Prior art]
We usually store fresh foods, such as spinach, cabbage, and Chinese cabbage, which we treat as foodstuffs in the vegetable storage room of the refrigerator. Therefore, vegetables that are classified as relatively large items such as cabbage and Chinese cabbage, and cucumbers that are generally sold in several units cannot be used all at once, and most are stored in the vegetable storage in the refrigerator. Will do. In this way, when these fresh foods are stored in the refrigerator for several days, they become less fresh and lose their original flavor and texture, eventually corroding and becoming unusable as foodstuffs, and most of them being discarded. Will be.
