Description
【０００１】[0001]
本考案は連続式凍結装置に関する。 The present invention relates to a continuous freezing device.
【０００２】[0002]
従来、被凍結物を凍結させるには、被凍結物へ連続的に冷風を吹き付けていた 。このため冷風の速度を上げるか、冷風の温度を下げることによりさらに早く凍 結すると考えられていた。 Conventionally, in order to freeze an object to be frozen, cold air was continuously blown to the object to be frozen. For this reason, it was thought that freezing would be quicker by increasing the speed of the cold air or decreasing the temperature of the cold air.
【０００３】 従来のダクト方式では直線部分の中間で冷風が吹き付けられ、熱交換はここを 中心に行われ、ノンダクト方式ではファンの下部分で熱交換が行われる。In the conventional duct system, cold air is blown in the middle of the straight line portion, and heat exchange is performed mainly there. In the non-duct system, heat exchange is performed in the lower portion of the fan.
【０００４】[0004]
従来のダクト方式では、ダクト付近での熱交換しか行われず、またノンダクト 方式では、冷風の吹き付けにムラが生じるので、被凍結物の表面と芯部分の温度 差が大きく、品物の表面の乾燥や品質劣化などが起こる。 In the conventional duct method, only heat exchange is performed in the vicinity of the duct, and in the non-duct method, the blowing of cold air becomes uneven, so the temperature difference between the surface of the frozen object and the core portion is large, and Quality deterioration occurs.
【０００５】 また、ダクト方式ではダクト部分の上部の保守が難しく、ノンダクト方式では ファンの回りがノーガードであるため危険なところとなっている。Further, in the duct system, maintenance of the upper part of the duct is difficult, and in the non-duct system, there is no guard around the fan, which is dangerous.
【０００６】[0006]
上記課題を解決するために本考案は、装置本体たる室体内に品物搬送用のコン ベアを設け、コンベア上の品物に冷風を吹きつける冷風の強風ゾーン、弱風ゾー ンをコンベアの移動方向に順次設けた構造のものとしている。 In order to solve the above-mentioned problems, the present invention provides a conveyer for conveying goods in the chamber which is the main body of the apparatus, and sets a strong wind zone of cold air for blowing cold air on the goods on the conveyor and a weak wind zone in the moving direction of the conveyor. The structure is provided sequentially.
【０００７】[0007]
品物の表面温度は冷風を弱くしたときに上昇し、強くすると降下する。温度の 低下した表面へ芯部分の熱が伝わるのを待ち、表面と芯部分の温度差が小さくな ったときに冷風をあてて品物表面の熱を奪うことが繰り返して行われることによ り温度ムラの少ない凍結がなされる。 The surface temperature of an item rises when the cold air is weakened and drops when it is strong. By waiting until the heat of the core is transferred to the surface where the temperature has dropped, and when the temperature difference between the surface and the core becomes small, cold air is applied to remove the heat of the surface of the item repeatedly. Freezing with less temperature unevenness is performed.
【０００８】[0008]
以下、図面に示す実施例により本考案方法を説明する。 Hereinafter, the method of the present invention will be described with reference to the embodiments shown in the drawings.
【０００９】 図１、２において符号１は装置本体たる室体で、水平な仕切板６により上下の ２空間Ａ、Ｂに区画されており、上部空間Ａには冷却器４、送風機７を設けてあ る。In FIGS. 1 and 2, reference numeral 1 is a chamber body which is a main body of the apparatus, and is divided into two upper and lower spaces A and B by a horizontal partition plate 6, and a cooler 4 and a blower 7 are provided in the upper space A. There is.
【００１０】 また、冷却室たる下部空間Ｂには水平なエンドレスコンベア２を設けてあり、 このコンベア２は前室３ａから本体内の前記下部空間Ｂを通過した後に後室３ｂ で反転し、下部空間Ｂ内を経て前室に戻り、ここで反転して再び前述のごとく移 動するようになっている。Further, a horizontal endless conveyor 2 is provided in the lower space B which is a cooling chamber, and the conveyor 2 passes through the lower space B in the main body from the front chamber 3a and then is inverted in the rear chamber 3b to After returning to the anterior chamber through the space B, it is inverted here and moved again as described above.
【００１１】 しかして前記仕切板（６）には前記コンベアへ冷風を吹き付けるための空気吹 出口用スリット５を多数あけてあるが、これらのスリットはコンベアの移動方向 と同方向に適宜の間隔をおいてあけてある。However, the partition plate (6) is provided with a large number of air outlet slits 5 for blowing cold air to the conveyor, and these slits are formed at appropriate intervals in the same direction as the conveyor moves. Set aside
【００１２】 したがって仕切板（６）の下方にはコンベアの流れ方向に冷風の強風ゾーンと 弱風ゾーンが交互に形成される。Therefore, a strong wind zone and a weak wind zone of cold air are alternately formed below the partition plate (6) in the flow direction of the conveyor.
【００１３】 すなわち、スリットの下方には強風ゾーンが、各スリット間の盲板部下方には 弱風ゾーンがそれぞれ形成される。That is, a strong wind zone is formed below the slits, and a weak wind zone is formed below the blind plate portion between the slits.
【００１４】 なお、これらの強風ゾーン、弱風ゾーンはスリットの開口面積、形状を適宜設 定することによっても形成できる。The strong wind zone and the weak wind zone can be formed by appropriately setting the opening area and shape of the slit.
【００１５】 この実施例のものでは、食品等の品物８はコンベア２によって搬送されるが、 コンベア上の品物は仕切板の前記スリット５下方の強風ゾーンを通る際にはスリ ットからの強冷風により表面が熱伝達作用で冷却される。In this embodiment, the product 8 such as food is conveyed by the conveyor 2, but the product on the conveyor is strong from the slit when passing through the strong wind zone below the slit 5 of the partition plate. The surface is cooled by the heat transfer action by the cold air.
【００１６】 品物が仕切板の盲板部下方の弱風ゾーンを通る際には、品物の芯部の熱が品物 の表面の熱伝導により移動し、表面と芯部との温度差が小となる。この表面と芯 部との温度差の小となった品物は次の強風ゾーンで表面が冷却され、次いで弱風 ゾーンで再び表面と芯部との温度差が小となり、以下同じ工程を繰り返すことに より品物は表面と芯部とに温度ムラのない状態に次第に凍結される。When the product passes through the weak wind zone below the blind plate of the partition plate, the heat of the core of the product is transferred by heat conduction on the surface of the product, and the temperature difference between the surface and the core is small. Become. If the temperature difference between the surface and the core is small, the surface is cooled in the next strong wind zone, then the temperature difference between the surface and the core is reduced again in the weak wind zone, and the same process is repeated. As a result, the product is gradually frozen so that there is no temperature unevenness between the surface and the core.
【００１７】[0017]
以上の説明から明らかなように、本考案によればは品物の表面と芯部分の温度 差を小ならしめて品物を冷凍または冷却でき、品質の劣化を防止できる。しかも 凍結、冷却時間は常時冷風を吹き付ける場合とほとんど差なく行なえる利点があ る。 As is clear from the above description, according to the present invention, it is possible to freeze or cool the product by reducing the temperature difference between the surface and the core of the product, and prevent the deterioration of quality. Moreover, the freezing and cooling time has the advantage of being almost the same as when constantly blowing cold air.
【００１８】 また、スリット板でよいのでダクトが不要となり、装置のコスト低減を期せる 。Further, since the slit plate is sufficient, the duct is not required, and the cost of the device can be reduced.
