（産業上の利用分野）
本発明は気流加熱方式に依る膨化食品製造装置に係り、
特にその排出装置の改善に関する。[Detailed description of the invention] 3. Detailed description of the invention (industrial application field) The present invention relates to a puffed food manufacturing apparatus using an air current heating method,
In particular, it relates to improvements in the ejection device.
（従来の技術）
膨化食品製造装置は、加圧高温下にある原料を急激に大
気圧又は減圧下に放出することで原料を膨化させるよう
にしたもので従来より種々のものが知られている。(Prior art) Various types of puffed food manufacturing equipment have been known in the past, which puff raw materials by suddenly releasing the raw materials under pressure and high temperature to atmospheric pressure or reduced pressure. .
この装置においては、全原料を均一に加熱処理し得ると

間で全原料均一に加熱でき。For this reason, the present applicant previously proposed in Japanese Patent Publication No. 46-34747 a heating tube for heating powdered or powdered food raw materials such as polished rice while flowing them in a flow path together with pressurized high temperature gas such as water vapor, and this heating tube. A collection device such as a cyclone that separates and collects the powdered or powdered food raw material heated by the pressurized high-temperature gas, and connected to the outflow side of this collection device,
Equipped with a discharge device consisting of a rotary valve that rapidly discharges the powdered or powdered food raw material into a low-pressure gas to C-swell, it can be used to remove materials such as polished rice that easily adhere to the walls of the device or that are likely to clump together. All raw materials can be heated uniformly in a short time without adhesion or caking.
しかも加圧高温ガスを大気中に逃がすこともなく、消エ
ネルギ化にも優れたＩＸ％流加熱方式に依る膨化食品製
造装置を提供した。In addition, the present invention provides a puffed food manufacturing apparatus using an IX% flow heating method that does not allow pressurized high-temperature gas to escape into the atmosphere and is excellent in energy consumption.
（発明が解決しようとする問題点）
しかしながら前記排出装置としてのロータリーバルブは
、ボディに対し可動部であるロータを有することから、
その摺動シール部から系外に加圧高温ガスが漏れ易く、
又そのメンテナンス回数が多くなりメンテナンスコスト
が高くなる。更にこのロータリーバルブは一定時間間隔
毎に所定量の原料を排出し、連続的な排出が行なわれな
いため、その後工程の装置である例えばサイクロン。(Problems to be Solved by the Invention) However, since the rotary valve as the discharge device has a rotor that is a movable part with respect to the body,
Pressurized high-temperature gas easily leaks out of the system from the sliding seal.
Moreover, the frequency of maintenance increases, resulting in higher maintenance costs. Furthermore, this rotary valve discharges a predetermined amount of raw material at regular time intervals, and since continuous discharge is not performed, it is necessary to use a subsequent process device such as a cyclone.
ロータリーフィーダ等に大きな変動的負荷をかけるとい
う問題がある。There is a problem in that a large variable load is placed on a rotary feeder or the like.
そこで本発明はかかる従来の問題点を解決すべく成され

さす、従って摺動シール部がなく加圧高温ガスが系外に
漏れ難く、メンテナンスコストが低く、しかも原料を連
続的に排出し得、後工程の装置等にも大きな変動的負荷
をかけることのない気流加熱方式に依る膨化食品製造装
置を提供するにある。Therefore, the present invention was made to solve such conventional problems, and its purpose is that the discharge device has a movable part, so there is no sliding seal part and the pressurized high temperature gas is released from the system. To provide a puffed food manufacturing device which is hard to leak, has low maintenance cost, can continuously discharge raw materials, and uses an air current heating method without imposing a large fluctuating load on devices in subsequent processes.
