一,Why do food-grade silicone hoses need to be certified
The U.S. Food and Drug Administration's rules on food contact materials and the European Food Safety Authority's rules on food safety are two examples of certification systems that the global food business often talks about.
When entering the production companies would also want their suppliers to have NSF International hygiene certification to make sure they are safe for a long time.
In general, becoming certified for food-grade silicone hoses is not just a way to show that they are of good quality; it is also a vital way to get into the international market.
二,The most critical fundamental standard is food contact safety.
most important thing to look for in food grade silicone hoses is how safe the material is to touch. In the international regulatory system, food-grade silicone materials usually have to meet the European Union's migration limit standards for materials that come into contact with food. The tests mostly look for heavy metals, volatile organic compounds, and any chemicals that might be left over.
moving is also a common test. Food grade silicone hoses of high quality should not smell while food is being moved. If they do, it could change the taste and quality of the food.
Some high-end food processing industries will also want materials that don't include bisphenol compounds to make food safety even safer.
三, Physical performance and mechanical strength standards
Not only should food-grade silicone hoses be safe, but they should also be strong. In general, the hardness of hoses is kept between Shore 50A and 70A.
If the hardness is too low, the pipe wall may collapse as fluids are moved; if the hardness is too high, the hose may not bend as well and be harder to install.
Tensile strength and elongation at break are also significant things to test. High-quality food-grade silicone hoses can stay stable even after being bent and used for a long time. This is especially crucial for automated food preparation lines.
Food-grade silicone hoses need to be able to handle a specific amount of pressure in many industrial settings, thus their pressure resistance must also be tested very carefully.
四,Temperature resistance is very important in the food sector.
In the food processing business, cleaning and sterilising commonly happen at high temperatures, hence hose materials need to be able to handle a wide variety of temperatures.
In general, high-quality food-grade silicone hoses may perform well in temperatures between -60 and 200 degrees Celsius. Hoses shouldn't become brittle in cold weather, and they shouldn't change shape too much in hot weather either.
When cleaning equipment, food companies commonly utilise steam disinfection or high-temperature circulating water. So, the thermal stability of materials has a direct effect on the safety of production and the life of the service.
Good temperature resistance can help businesses save money on maintenance and running costs by making it less likely that their equipment will break down.
五, Design of sanitary structures and trends in the future of the industry
To keep microporous formations from forming, the inside of food grade silicone hoses must be as smooth as possible. Too many micropores can make it easy for bacteria to grow, which makes food transportation less safe.
In the current food business, hygiene control is becoming more and more important during manufacturing. Many organisations pick suppliers that have been accredited by the International Organization for Standardisation quality management system.
The future of the food grade silicone hose industry will be based on protecting the environment and making materials more stable over time. As automation in the food business gets more and better, materials that are resistant to ageing and don't migrate will become new areas of technological rivalry.
