一, Basic needs for the piping system of a water dispenser
Can food grade silicone s piping system is generally in charge of moving filtered water, mineral water or purified water from the storage tank to the tap or outlet. The safety and flavour of drinking water are directly affected by the materials and performance of pipes. The main needs are:
Safety when food comes into contactDrinking water is a type of direct entry meal, and the pipes must be safe and not release any dangerous elements.must meet food contact safety criteria set by the FDA, LFGB, or GB 4806, for example.You can't move heavy metals, organic solvents, or plasticisers.
Control of taste and smellThe water quality of the water dispenser is sensitive to smells. If there is any smell or chemical smell in the pipe, it will change the taste of the water coming out of the tap.The pipe must not smell bad and should not let smells move through it even after being used for a long time.
Resistance to heat and cleaningA water dispenser can give you cold, warm, or even hot water.The pipe material must be able to handle both hot and cold water and be able to be cleaned and disinfected many times.Support flushing with hot water and disinfecting with steam (like high-temperature sterilisation for household usage or CIP for commercial water dispensers).
Easy to install and flexibleThe water dispenser's inside space is small, thus the pipes need to be able to bend and flex easily so that they can be installed and maintained.The smooth inner wall cuts down on scaling and microbiological debris.
二, What food-grade silicone tubing is like
1.Very safe
food grade silicone tubing, no plasticisers, and no BPA
Can touch drinking water directly for a long time without making it dirty
2. Very resistant to both hot and cold weather
Silicone tubing that is safe for food can handle temperatures between -40 ° C and +200 ° C.
It can be used to get cold, warm, and even hot water out.
Can take numerous hot water washes without getting older or changing shape
3. Low odour and taste stability
After strict sensory testing and control of volatile substances,
It won't change the flavour of the water, even after cleaning it at a high temperature or using it for a long time.
Check that the water dispenser's water is clean and tastes good.
4. Elasticity and Flexibility
The pipe is flexible and may bend easily in a small area.
Good strength, not easy to fold or block
A smooth inner wall stops scale and germs from growing.
三, Where to use food-grade silicone tubing in water dispensers
Pipeline for cold water
From the tank that holds the water to the place where it comes out
High standards for smell and taste
Pipeline for warm water
The pipe that comes out after the heater
Material stability still needs to be kept up even when the temperature is high.
Hot water pipeline (certain water dispensers that work at high temperatures)
Help the hot water function
Can withstand high temperatures and steam cleaning
Pipe that connects the filter element
Small pipes used to clean water or for mineral water equipment
The material ought to be easy to put together and take apart and flexible.
四,Tips for choosing food-grade silicone tubing
1. Level of certification
Basic food grade: safe and reliable for use in most domestic water dispensers
High-quality food grade (FDA/LFGB): good for equipment that is sensitive to the mouth or for export
Medical grade: You can choose between high-end water dispensers or laboratory-grade water systems.
2. The thickness of the pipe and the size of the wall
Choose the right pipe size based on how much water it can move and how it connects to other equipment.
The wall thickness makes it strong against pressure, flexible, and easy to put up.
3. Performance under high temperatures
You can use regular food-grade silicone tubing for water lines that are at room temperature.
To keep hot water pipes or steam disinfection pipes from bending or getting older, they should be built of silicone tubing that can handle high temperatures.
4. How long it lasts and how to take care of it
Check regularly and replace right away if you see cracks or smells.
Support hot water flushing and steam disinfection to make things last longer.
五, Benefits of utilising silicone tubing that is safe for food
1.Make sure the water is safe to drink.
2.Not harmful or hazardous, and keeps pollution from happening
3.Keep the flavour of the water clean.
4.No smell migrating, steady feeling of water coming out
5.Be able to operate in a variety of settings
6.You can use cold, warm, or hot water.
