It mainly consists of a rack, stainless steel frame, water inlet pipeline, bottle clamping head, track, lower water receiving tray, upper water blocking tray, and organic glass cover. After the bottle is positioned, the bottle mouth is clamped and turned 180 degrees upside down for flushing. After flushing, it is then turned 180 degrees to the conveyor chain, which can effectively flush the bottle inside and outside, and avoid splashing of the flushing liquid. It has excellent maintenance interchangeability and reliability.
