一. Safety and materials are the most important things
The first thing to think about when choosing food grade silicone tubing is the safety and the material. When making actual food grade silicone tubing, they employ high-purity silicone rubber that doesn't have any heavy metals, plasticisers, or other dangerous substances in it. When this kind of material comes into touch with food or drinks, it goes through a lot of processing to make sure that no dangerous compounds are discharged.
Food-grade silicone tubing must also have the right certifications, including FDA certification in the US or LFGB certification in Germany. To make sure that these silicone tubes don't put food safety at risk when used in high heat, high pressure, or acidic or alkaline situations, they need to be certified.high-quality clear silicone tubes should seem perfectly clear, with no bubbles or other imperfections. This makes them look nice and makes it easy to see the movement of liquid inside the tube. The tube's pure material doesn't age or turn yellow
二. Temperature resistance determines the scope of use
When choosing silicone tubing, you should keep in mind that food processing and beverage transportation environments often have high or low temperatures. In general, regular food-grade silicone tubing may be used at temperatures between -60 °C and 200 °C for a long time. It can even handle short bursts of high temperatures up to 250 °C.
Different situations call for different levels of temperature resistance. For instance, pipes in coffee machines, hot water distribution systems, or steam disinfection systems need to be able to handle temperatures over 100 °C. On the other hand, pipes in refrigerators or freezers need to stay flexible and not become brittle at low temperatures. You can choose pipes with a larger temperature range and more reliable performance based on how you plan to use them
三. The thickness and flexibility of the wall
The thickness and elasticity of silicone tubing have a direct impact on how well it works and how long it lasts. Thin-walled tubes are soft and flexible when they bend, which makes it easy to see how the liquid flows. However, they can't handle as much pressure. Thick-walled pipes are a little less flexible, but they can handle more pressure and are better for high-pressure or mechanical extrusion environments.
四. The length and diameter of the pipe
The right inner and outer diameters are the most important things to think about when it comes to smooth transportation and quick installation. A tiny inner diameter can easily cause a clog, whereas a big inner diameter can slow down the flow. When it comes to basic food-grade clear silicone tubing, the inner diameter can be anywhere from 2mm to 25mm, depending on the needs of the equipment and the flow of the liquid.
The outer diameter is normally the inner diameter plus twice the wall thickness. when choosing, you should think about the inner diameter, wall thickness, and equipment interface size all at once. When it comes to length
五. Resistance to chemical corrosion and service life
When used in diverse liquids, food-grade clear silicone tubing needs to be able to withstand chemical deterioration. Silicone tubing of good quality can handle acid and alkali, and it can also carry greasy liquids like milk and cream. It won't get old easily while cleaning and disinfecting, either.
High-quality food-grade clear silicone tubing usually lasts for 3 to 5 years. In cases of high temperature, acidity, or alkalinity, or frequent use, however, regular checks are still needed. If you check the pipes for cracks, hardness, yellowing, and other signs of wear and tear and replace them on time, you can make sure that food and transportation are safe.
六. Report on Testing and Certification
When buying food-grade clear silicone tubing, you can't overlook certification and testing reports. The FDA and LFGB certifications are the most fundamental food safety standards. The ROHS certification makes sure that there are no dangerous heavy metals in the food. Along with certification, manufacturers' reports on physical performance are also significant.
七. Things to keep in mind when using
1.There are a few useful tips to keep in mind while utilising food-grade clear silicone tubing:
2.Pick pipes that can handle the temperature and pressure of the environment where they will be used to prevent going over the limit.
3.To avoid becoming older, don't be around strong acids, alkalis, or ultraviolet radiation for long periods of time.
4.Cleaning the pipeline on a regular basis will keep pollution and dirt from building up.
5.Keep an eye on the pipe while you're using it to see if it bends, cracks, or becomes yellow. If you see any of these things, replace the pipe right away.
