摘要：本发明提供一种用于冷冻食品的锁鲜液及其制备设备，涉及锁鲜液制备技术领域，包括机体和连接结构，所述机体的一侧开设有进气口，所述机体远离进气口的一侧安装有膨胀机，所述机体的两侧均固定连接有阀门，所述机体靠近进气口的一侧安装有若干个连接阀，所述机体靠近连接阀的一侧安装有连接装置，所述膨胀机远离机体的一端设有连接结构，所述连接结构包括连接头，所述连接头与膨胀机固定连接，所述连接头的内壁开设有若干个限位槽，所述限位槽的内壁滑动连接有连接杆。本发明解决了，现有技术中需要将锁鲜液生产设备中的膨胀机与外接管道进行连接进行使用，现有的都是使用多个螺母进行连接，导致在安装和拆卸过程中较为繁琐的问题。

摘要：【中文】本发明提供一种用于冷冻食品的锁鲜液及其制备设备。所述用于冷冻食品的锁鲜液及其制备设备包括以下成分：乙醇、硝酸钾、植物油、F42果葡糖浆、氯化钾和水，各组分含量为乙醇15％‑25％、硝酸钾5％‑10％、植物油5％‑8％、F42果葡糖浆15％‑25％、氯化钾5％‑12％和水35％‑40％。本发明提供的用于冷冻食品的锁鲜液及其制备设备，可以在短时间内将被冻物品的热量通过微冻液处理，使被冻食品型槽冰晶生成区，使食品细胞内外的压力相对达到平衡，大大的保护被冻物品的细胞组织，保持细胞活性，保证被冻物品的鲜活质量，最大限度保留原营养成分，而且具有定量进料功能，通过采取从上往下进行排放锁鲜液，避免加工槽配料反应后的凝固残杂跟随锁鲜液进行排放，极大程度上提高了锁鲜液的质量。 【EN】The invention provides a fresh-keeping liquid for frozen food and a preparation device thereof. The fresh-keeping liquid for frozen food and the preparation equipment thereof comprise the following components: 15-25% of ethanol, 5-10% of potassium nitrate, 5-8% of vegetable oil, 15-25% of F42 high fructose corn syrup, 5-12% of potassium chloride and 35-40% of water. The fresh-keeping liquid for frozen food and the preparation equipment thereof can process the heat of the frozen object through the micro-freezing liquid in a short time, so that the pressure inside and outside the food cells is relatively balanced, the cell tissue of the frozen object is greatly protected, the cell activity is kept, the fresh and alive quality of the frozen object is ensured, the original nutritional ingredients are kept to the maximum extent, the fresh-keeping liquid has a quantitative feeding function, the fresh-keeping liquid is discharged from top to bottom, the solidification residue after the batching reaction of a processing tank is prevented from being discharged along with the fresh-keeping liquid, and the quality of the fresh-keeping liquid is greatly improved.
