啤酒、汽酒、汽水、矿泉水等都是含有溶解CO_2达到饱和状态的饮料,在灌装过程中为了防止液体内溶解气体溢出损失,必须使容器预加压到气体相应饱和溶解压力再灌装,即所谓等压灌装。B·ZP.D—YG40—8型灌压机是我国七十年代开始仿制西德用于灌装含气液体的自动灌压 Beer, sparkling wine, soft drinks, mineral water and so on all contain the dissolved CO2 to reach the saturated state of the beverage. During the filling process in order to prevent the liquid from dissolving the gas overflow loss, the container must be pre-pressurized to the gas corresponding saturation dissolving pressure and then filling, The so-called pressure filling. B · ZP.D-YG40-8 filling machine is the beginning of the seventies in China imitation of West Germany for automatic filling of gas filled liquid pressure
