盐水注射机是将腌制液注射到原料肉中的设备。由压力泵、贮液槽，注射针及传送带等部分构成，注射针的针管的侧壁上有许多小孔，腌液可以从小孔流出，国内生产的盐水注射机多半是单针头手动或半自动的。现代化大型工厂多采用多针头盐水注射机，并实现自动化工作时，将配好净化后的腌制液装入贮液装置中，贮液装置与注射针的针管有压力阀相通。作业时，称重后的肉片放在喂料传送带上，然后从注射针下部通过。通过加压阀门使贮液槽中的腌制液进入注射针管中，当针头冲碰到肉片时开始注射盐水，针头恒速下降。针头上升时，停止注射，盐水注射机配有10至数百根注射针管，通过注射针的上下运动，把腌制液定量、均匀。连续的注射入原料肉中

The brine injection machine is the equipment to inject the pickled liquid into the raw meat. By the pressure pump, sump, needle and conveyor belt and other parts, there are many small holes side wall of the injection needle needle, liquid outflow from the orifice can be cured, saline injection machine of domestic production is mostly single needle manually or semi automatically. Modern large factories mostly use multi needle brine injection machine, and realize automatic operation. The purified pickling fluid will be loaded into the liquid storage device. The liquid storage device is connected with the needle tube of the injection needle with pressure valve. During the operation, the weighed slices of meat are placed on the feeding conveyor belt and then passed from the lower part of the injection needle. Through the pressure valve so that the tank in the pickling liquid into the injection needle, when the needle punching met meat began to saline, constant speed drop needle. When the needle rises, the injection is stopped and the brine injection machine is equipped with 10 to hundreds of injecting needles, and the pickled liquid is quantified and evenly carried out through the upper and lower movements of the injection needle. Continuous injection into the raw meat

盐水注射机的分类：盐水注射机是在静脉注射的基础上发展起来的，但是由于屠宰分割时很难保证脉管的完整，这种方法逐渐被淘汰，只有在加工某些用整只猪后腿加工的西式高档火腿时，仍采用这种注射方法，目前的盐水注射机，都是以肌肉注射的方式进行的，从用途上，可以分为不带骨盐水注射机，带骨注射机，注射、嫩化两用机，但事实上，目前最先进的盐水注射机通过更换针头，大多既能注射带骨肉块，又能注射去骨肉块，还能进行嫩化处理 。

The classification of saline injection machine: saline injection machine is developed on the basis of the intravenous injection, but because of the slaughter segmentation is very difficult to guarantee the vascular integrity, this method gradually be eliminated, only in some pig hind legs with the whole processing of high-grade Western-style ham processing, is still the injection method, saline injection machine at present, are carried out by intramuscular injection way, from the use of, can be divided into the machine with no bone with bone saline injection, injection machine, injection machine, tender, but in fact, saline injection machine is currently the most advanced by replacing the needle head, most of which can injection with bone block, and can also go to block blood injection, tender treatment.
