灌肠机是往肠衣中灌装肉馅等所使用的机械，分为气压式、油压式、电动式灌肠机三种形式。根据是否抽真空，是否定量，又可分为真空定量灌肠机、非真空定量灌肠机和一般灌肠机。另外还有一种真空连续填充定量结扎机，从填充到结扎都是连续进行的，可大大提高生产能力。
Enema machine is a kind of machine used to fill meat stuffing into casing. It can be divided into three types: air pressure type, oil pressure type and electric enema machine. According to whether to vacuum or not, it can be divided into vacuum quantitative enema machine, non vacuum quantitative enema machine and general enema machine. In addition, there is a vacuum continuous filling quantitative ligation machine, which is continuous from filling to ligation, which can greatly improve the production capacity.
气压式灌肠机是利用气压来驱动，在圆形气缸的上部有一个小孔，在此安装灌装用的喷嘴，在气缸的下部有用压缩空气推动的活塞，通过气压推动活塞，把肉馅挤压出来，灌入肠衣。
The air pressure type enema is driven by air pressure. There is a small hole in the upper part of the circular cylinder. A nozzle for filling is installed here. A piston pushed by compressed air is used in the lower part of the cylinder. The piston is pushed by air pressure to squeeze out the meat filling and pour it into the casing.
