一,What makes food silicone tubing different from normal tubing
In today's food processing and transportation systems, the choice of pipeline materials has a direct effect on food safety and how well production works. Food grade silicone tubing is a high-performance pipe made specifically for moving food grade materials. Ordinary tubing, on the other hand and it normally has to meet tight food safety certification standards. in the international standard system, food contact materials must follow the rules set by the US Food and Drug Administration and the EU Food Safety Agency to make sure that harmful compounds don't come out when they are in touch with food for a long time or at high temperatures.
二, The discrepancy between safety regulations and material formulas
Food silicone tubes are formed of high-purity silicone polymer materials. During the production process, the amount of additives is rigorously managed to keep plasticisers, heavy metal stabilisers, and dangerous volatile compounds out of the tubes. This kind of pipe is chemically stable and won't move chemicals around too much even after being in contact with food media like milk, juice, and vegetable oil for a long time.
Some regular pipeline materials may incorporate plasticisers or strengthening compounds to lower the cost of making them. Some cheap PVC pipes can let out small amounts of toxic chemicals when they are hot, which could be dangerous if they are used to move food.
三, Differences in hygiene performance and antibacterial ability
Food silicone tubing usually has a smooth inner wall, a low friction coefficient, and is less likely to leave behind residue when moving fluids. This is especially important for dairy production lines since the protein and fat in milk can stick to the walls of the pipes. If the pipes are rough, it can readily breed germs.
In the medical and food industries, pipeline systems often need to be disinfected at high temperatures on a regular basis. Food silicone tubing can usually handle steam disinfection at high temperatures and usually stays stable at greater temperatures.Regular pipes don't do a very good job of keeping things clean, and the inside walls are very rough. Using it for a long time can easily create biofilms, which makes it more likely that microbes will thrive.
四, Differences in temperature resistance and service life
Food silicone tubing can normally perform reliably between -60 and 200 degrees Celsius, which is a wide range of temperatures. It can still keep its good elasticity and mechanical strength even while it's being transported in high-temperature steam sterilisation or low-temperature refrigeration.
The range of temperatures that regular pipes can handle is not very wide. some PVC regular pipes may soften and change shape in high heat, whereas rubber regular pipes are more likely to shatter as they get older when exposed to high heat for a long time.If you clean and care for high-quality food silicone tubing according to the instructions, it should last for several years without any problems. Because the materials aren't very stable, regular pipes don't last as long.
五,Suggestions for choosing an application industry and where to buy
Food silicone tubing is mostly used in a number of high-end industrial areas.It is often utilised in systems for moving milk, pipelines for processing juice, and equipment for brewing beer. In healthcare, food-grade silicone tubing is also used to transport drugs and as equipment for biological experiments.
Food silicone tubing is also very useful in the water treatment industry and for transporting high-purity fluids.There are a few things to think about while purchasing food silicone tubing.you need to make sure that the product has full food safety certification. Next, you need to evaluate how smooth and elastic the inside wall of the pipeline is. you need to know how well the pipeline resists pressure and how well it works against ageing
六,How to judge the quality of food silicone tubing
You can tell how good food silicone tubing is by looking at it, feeling it, and doing tests on it.High-quality food silicone tubing usually looks clear, has walls that are the same thickness all the way around, and has no evident imperfections. When you press it with your hands, it instantly regains its shape and doesn't get hard or brittle.High-quality food silicone tubing usually doesn't have a strong smell. If you can smell industrial rubber, it usually means that the substance isn't pure enough.If the weather is good, a simple test in hot water can be done. In hot water, high-quality food silicone tubing won't make the tube wall cloudy or change colour.
