Zusammenfassung: | To provide an improved device and method for applying a wetting fluid to one-way pressure relief valves to ensure more effective closure of the valves.SOLUTION: A wetting fluid applicator unit applies a wetting fluid to pressure relief valves during packaging of a product, such as roasted coffee, with a packaging system. The wetting fluid applicator unit includes an unpressurized wetting fluid reservoir which supplies the wetting fluid to multiple fluid supply circuits. One fluid supply circuit charges a spray head with the wetting fluid while the other fluid supply circuit is replenished with the wetting fluid from the unpressurized reservoir. The wetting fluid applicator unit ensures a continuous flow of the wetting fluid to the spray head while enabling replenishment of the reservoir during continuous operation of the packaging system.SELECTED DRAWING: Figure 9
【課題】弁のより効果的な閉鎖を確実にするために、一方向圧力開放弁に湿潤流体を適用する改良された装置及び方法を提供する。【解決手段】湿潤流体アプリケータユニットは、包装システムで焙煎コーヒーのような製品の包装中に、湿潤流体を圧力開放弁に適用する。湿潤流体アプリケータユニットは、複数の流体供給回路に湿潤流体を供給する非加圧湿潤流体リザーバを含む。一方の流体供給回路はスプレーヘッドに湿潤流体を充電し、他方の流体供給回路は非加圧リザーバから湿潤流体を補充する。湿潤流体アプリケータユニットは、包装システムの連続運転中にリザーバの補充を可能にしながら、スプレーヘッドへの湿潤流体の連続的な流れを確保する。【選択図】図9 |
