Description

本発明は、玄米等の穀物に含まれるγ−アミノ酪酸（「ＧＡＢＡ」）を富化させたり、精米加工前の玄米を加温加湿処理したりする場合等に使用する穀物加温加湿装置に関する。   The present invention relates to a grain heating and humidifying apparatus used when enriching γ-aminobutyric acid (“GABA”) contained in grains such as brown rice or when heating and humidifying brown rice before milling. .

従来、穀物に含まれるγ−アミノ酪酸（「ＧＡＢＡ」）を富化させる場合に使用する穀物加温加湿装置が知られている（特許文献１を参照。）。
当該穀物加温加湿装置は、穀物を上方から下方へ流動させるタンクと、該タンクの一側に配設され前記タンク内へ加湿温風を送風する送風洞と、前記タンクの他側に配設され前記タンク内から加湿温風を排風する排風洞を備える。 2. Description of the Related Art Conventionally, a grain warming / humidifying device used when enriching γ-aminobutyric acid (“GABA”) contained in a grain is known (see Patent Document 1).
The grain heating / humidifying device includes a tank that allows grains to flow downward from above, a ventilation passage that is disposed on one side of the tank and blows humidified warm air into the tank, and is disposed on the other side of the tank. And an exhaust tunnel for exhausting the humidified hot air from the tank.

前記タンク内には、前記送風洞から加湿温風が送風される複数の送風管と、前記排風洞へ加湿温風を排風する複数の排風管が平行して横設される。前記複数の送風管と前記複数の排風管はともに多孔壁を有する。   In the tank, a plurality of air ducts through which the humidified warm air is blown from the air duct and a plurality of air exhaust pipes for exhausting the humidified warm air to the exhaust air duct are installed in parallel. Both the plurality of air ducts and the plurality of exhaust pipes have a porous wall.

そして、送風ファンの作用により前記送風洞に送風される加湿温風は、さらにタンク内に横設される前記送風管に送風されて該送風管の多孔壁から前記タンク内へ流出し、前記タンク内において上方から下方へと流動する穀物を加温加湿する。
また、前記穀物を加温加湿した後の加湿温風は、吸引ファンの作用により、前記送風管と平行してタンク内に横設される前記排風管の多孔壁から該排風管へ流入し、前記排風洞から機外へ排風される。 Further, the humidified warm air blown to the blower tunnel by the action of the blower fan is further blown to the blower pipe disposed laterally in the tank and flows out from the porous wall of the blower pipe into the tank. Warm and humidify the grains that flow from top to bottom.
Further, the humidified warm air after warming and humidifying the grain flows into the exhaust pipe from the porous wall of the exhaust pipe that is installed in the tank in parallel with the blower pipe by the action of the suction fan. Then, the air is exhausted from the exhaust tunnel to the outside.

ところで、前記穀物加温加湿装置においては、通常、前記送風洞と前記排風洞のそれぞれの壁面に静圧検出用開口が設けられ、前記各静圧検出用開口に接続されるチューブを差圧計（例えばマノメータ）に接続することで、前記送風洞と前記排風洞との間の差圧、即ち加湿温風が通風する前記タンクの上流側と下流側との間の差圧を検出し、前記タンク内における圧力損失を測定して、当該タンク内における加湿温風の通風状態を確認している。   By the way, in the grain heating / humidifying device, normally, a static pressure detection opening is provided in each wall surface of the air duct and the exhaust duct, and a tube connected to each of the static pressure detection openings is connected to a differential pressure gauge ( For example, a differential pressure between the air duct and the exhaust duct, that is, a differential pressure between the upstream side and the downstream side of the tank through which the humidified hot air flows is detected. The pressure loss in the tank is measured, and the ventilation state of the humidified warm air in the tank is confirmed.

しかしながら、前記穀物加温加湿装置は、加湿温風を通風させるため、前記チューブ内において高温加湿状態の空気が冷却されて結露を生じる結果、前記差圧を正確に検出できなくなる問題がある。   However, since the grain warming / humidifying device causes humidified warm air to flow, there is a problem in that the differential pressure cannot be accurately detected as a result of cooling the high-temperature humidified air in the tube and causing condensation.

特開２０１０−２４３１１９号公報JP 2010-243119 A

そこで、本発明は、結露に影響されることなく、送風洞と排風洞との間の差圧を正確に検出することができる穀物加温加湿装置を提供することを目的とする。   Then, an object of this invention is to provide the grain heating and humidification apparatus which can detect correctly the differential pressure | voltage between an air duct and a wind tunnel without being influenced by dew condensation.

Then, the condensed water accumulated in the drain trap 5 may be discharged by removing the cap at an appropriate time.
Further, the cap can be removed from the drain drain opening 53 when the apparatus is operated. If the cap is removed from the drain drain opening 53, the apparatus can be operated while draining condensed water.

本発明の実施の形態における穀物加温加湿装置は、前記ドレントラップ７が送風洞２の壁面２４に設けられる静圧検出用開口２２に対向する壁面５１を有するため、高温加湿状態の空気が前記ドレントラップ５の壁面５１で冷却されて結露する。
したがって、本発明の実施の形態における穀物加温加湿装置によれば、前記ドレントラップ５の静圧測定用開口５２と差圧計４を接続する配管２３内で結露する結露水の量を減らすことができるため、結露に影響されることなく、送風洞２と排風洞３との間の差圧を正確に検出することができる。 In the grain heating and humidifying apparatus according to the embodiment of the present invention, the drain trap 7 has a wall surface 51 facing the static pressure detection opening 22 provided in the wall surface 24 of the air duct 2, so that the air in a high-temperature humidified state is It is cooled by the wall surface 51 of the drain trap 5 and dew condensation occurs.
Therefore, according to the grain heating / humidifying device in the embodiment of the present invention, the amount of condensed water condensed in the pipe 23 connecting the static pressure measuring opening 52 of the drain trap 5 and the differential pressure gauge 4 can be reduced. Therefore, the differential pressure between the air duct 2 and the exhaust duct 3 can be accurately detected without being affected by condensation.

Since the static pressure measurement opening 52 is provided on the side and the drain discharge opening 53 is provided on the lower corner side, the dew condensation water can be collected below the drain trap 5 and collected in the drain trap 5. Almost all the condensed water can be drained from the drain drain opening 53.

本発明の実施の形態における穀物加温加湿装置は、前記ドレントラップ５の静圧測定用開口５２が当該ドレントラップの壁面５１の上部であって前記静圧検出用開口２２よりも上方位置に設けられている一方、当該ドレントラップの壁面５１の下部にドレン排出用開口５３が設けられるものであれば、前記壁面５１が必ずしも四角形状でなくてよく、その場合でも、前記ドレントラップ７の壁面５１全体を、高温加湿状態の空気を結露させるために有効に活用できるとともに、前記静圧測定用開口５２が前記ドレントラップ７の壁面５１を流れ落ちる結露水や前記ドレントラップ５内に溜まる結露水の影響を受けることがない。   In the grain heating and humidifying apparatus according to the embodiment of the present invention, the static pressure measuring opening 52 of the drain trap 5 is provided above the wall surface 51 of the drain trap and above the static pressure detecting opening 22. On the other hand, if the drain discharge opening 53 is provided below the wall surface 51 of the drain trap, the wall surface 51 does not necessarily have a rectangular shape. The whole can be effectively used to condense the air in a high-temperature humidified state, and the influence of the dew condensation water that the static pressure measurement opening 52 flows down the wall surface 51 of the drain trap 7 or the dew condensation water accumulated in the drain trap 5 Not receive.

Although connected to the differential pressure gauge 4 via the drain trap 5, a similar drain trap is also provided outside the wall surface of the wind tunnel 3 where the static pressure detection opening 32 is provided to detect the static pressure. The opening 32 can be connected to the differential pressure gauge 4 through a drain trap.
In the grain heating and humidifying apparatus according to the embodiment of the present invention, if a drain trap is also provided outside the wall surface of the wind tunnel 3 where the static pressure detection opening 32 is provided, the static pressure of the drain trap is measured. Since the amount of condensed water condensed in the pipe 33 connecting the opening for measurement and the differential pressure gauge 4 can also be reduced, the pressure difference between the air duct 2 and the exhaust duct 3 can be further increased without being affected by condensation. It can be detected accurately.
