Dairy hose, from the name we can know its usage. It’s a food hose that conveys milk, lipid fluids and other beverages. However, it is precisely because the objects it serve are special. So people more and more focus on its safety and hygiene. Then what are the standards for this kind of food hose? Let’s take a look at it in detail below.
First, let’s take a look at the material of the dairy hose
Since it belongs to the food hose, the inner rubber of the pipe must meet the food hygiene grade. For example, smooth and seamless nitrile rubber. This material has passed the FDA and CE certificate. Thus it guarantees good safety in use. As for its outer glue, the most used one is synthetic rubber. In terms of color, like ordinary hoses, the inner wall is white. While the outer wall is natural blue.
The second is its usage environment. This kind of hose can not bear negative pressure. Otherwise it will deforms due to extrusion. Then this will affect the quality of the medium and the further use. Its working pressure should not exceed 10bar. As for the temp, the milk hose can work normally in -20℃-80℃.
Finally, there are some precautions that you should focus on. Milk delivery hoses can deliver milk or alcoholic beverages. But you should clean the inner wall before delivery. After each work, you also need to clean it in time to ensure normal use next time. In addition, the food hose resists a certain impact. But you should try to avoid collisions with various hard and heavy objects.
In fact, in addition to the milk delivery hose, there is also a suction hose. Such food suction hose can bear negative pressure. When you combine these 2 hoses, it becomes the milk hose that we often mention.
