一,Basic traits and uses
1. Food grade silicone hoses are usually made of silicone that meets FDA and EU regulations for food contact. The primary features are as follows: High temperature resistance: can handle temperatures from -60 °C to +200 °C and can handle even higher temperatures for brief periods of time.
2. Safe and not hazardous: doesn't have heavy metals, plasticisers, or other harmful compounds. Strong corrosion resistance: can handle a wide range of foods, drinks, and mild chemical solutions. Good flexibility and transparency make it easy to see how fluids are moving and easy to install and bend.
3. It can keep working well even when it's hot and bent over and over again. These features make food silicone hoses highly popular in equipment for making sugar, baking, and delivering drinks like beer, juice, and milk. In these situations, the hose's inner diameter has a direct effect on the flow rate, pressure, and how well it fits with the equipment interface.
二, Is it possible to change the inner diameters of food-grade silicone hoses
1. Specifications for standard inner diameters
Food silicone hoses on the market usually have inner diameters of 3mm, 6mm, 8mm, 10mm, 12mm, 16mm, 20mm, and so on. Most manufacturers offer a choice of standard inner diameters.
2. Customisation that isn't standard
The manufacturer can make non-standard inner diameters if the conventional ones don't work for the equipment or process flow. These can be anything from 1mm to 100mm or even bigger. The inner and outer diameters, the temperature range, the pressure requirements, the regulations for food contact, the length requirements, and if they have threaded or flanged interfaces
3. Materials and hardness that are made to order
Changing the inner diameter can also change the choice of hose wall thickness and hardness. If something is too thin, it might not be able to hold enough pressure or break easily. If it is too thick, it might not be able to bend. The manufacturer will choose the right materials and hardness based on the specifications for the inner diameter to make sure it is safe to use.
三,The technique of changing the inner diameter of food-grade silicone hoses
1. Talking about requirements
The customer tells us about the environment where the fluid will be used, the type of fluid, the pressure, the temperature, and the interface.
2. Evaluation of the technology
To see if something is possible, the maker figures out the pressure and flow rate depending on the inner and outer diameters, wall thickness, and operating circumstances.
3. Making samples
Make sample hoses based on custom plans and do flow, pressure, and food safety tests on them.
4. Confirmation and making a lot of them
Once the sample has been checked for accuracy, it goes into mass production, where it can usually be made longer, harder, or a different colour.
5. Check the quality and send it out
To make sure they meet standards, each batch of hoses must be tested for size, safety when in contact with food, and resistance to high and low temperatures. Customers can get personalised food silicone hoses that fit their needs by following the steps above.
四, How the inner diameter affects applications when it is customised
1. Improving traffic
Different inner diameters have a direct effect on the flow rate, which makes sure that the production process is efficient.
2. Changing the pressure
The right inner diameter can keep the pressure of liquids or gases in the system stable, which lowers the chance of leaks or damage.
3. Matching the equipment interface
The inner diameter is a perfect fit for the device interface so that connector adapters don't cause pollution or blockages.
4. Safety of the process
A reasonable inner diameter and wall thickness, along with the right climate for use, helps keep hoses from breaking or bending and make operations safer.
五, Precautions for customizing silicone hoses for food
1. Limits on pressure and temperature
If the inner diameter gets bigger, the wall thickness may get thinner and the pressure bearing capacity may go down. The fluid working pressure needs to be taken into account.
2. Flexibility and bending radius Too much or too little inner diameter might change how flexible and bendy the hose is, so make sure to leave enough room when you install it.
3. Standards for safety and materials
Food contact materials can't be utilised in the food sector unless they meet FDA, LFGB, or EU criteria.
4. Colour and ID
When customising, you need to say ahead of time if you need clear hoses or colour indications for different food processing methods.
5. Consistency in batches
When customising something that isn't standard, you need to make sure that the size of each batch of items is the same. If not, it could mess with connections between machines and the production process.
