一, Basic features of food-grade silicone tubing
resilience to high temperatures
Food-grade silicone tubing can normally handle temperatures between -60 °C and 230 °C, however certain high-performance materials can even handle temperatures up to 300 °C. It may therefore be completely employed at the normal operating temperature of steam ovens, which is normally between 100 °C and 200 °C.
Very stable chemically
Silicone tubing doesn't react easily with water, oil, or acidic or alkaline chemicals, which helps maintain the pipeline clean and keeps food from getting dirty or smelling bad.
Soft and hard to bend
Silicone tubing is flexible and easy to bend, so it's easy to build pipelines within the oven. It can also stretch and bend a little without breaking.
Certification for Food Safety
To make sure that food grade silicone tubing is safe to touch, it usually meets the standards set by the FDA (US Food and Drug Administration), LFGB (German Food Safety Certification), or GB 4806 (Chinese Food Safety Standard).
二, What silicone tubing needs to work in a steam oven
Steam atmosphere with high temperatures
A steam oven makes steam that is very hot, usually between 100 °C and 130 °C, but it can get up to 150 °C in a short amount of time. In this environment, regular food-grade silicone tubing may usually last a long time. However, with time, the tubing may start to age, become yellow, or become a little harder because of the constant high temperature.
A place with a lot of humidity
There is a lot of moisture in the steam oven, and the pipes are likely to be exposed to water vapor for a lengthy time. Silicone tubing doesn't soak up water or get bigger, although being wet and hot for a long time may speed up aging. So, it's very crucial to get silicone tubing that can handle high temperatures and steam.
Things that cause stress
Steam oven pipelines normally have a little bit of pressure on them, but if the design of the pipeline isn't good, too much pressure in one area might make the silicone tube expand or leak water. So, you need to get silicone tubing with the right wall thickness and high pressure resistance.
safety of food
The pipes must fulfill food grade standards because the steam from the steam oven comes into direct contact with the food or circulates in the water tank. This is to make sure that dangerous compounds or smells are not emitted during the cooking process.
三,Things to keep in mind while utilizing food grade silicone tubing
Pick a model that can handle high temperatures.
Some silicone tubes can handle more heat than others. To make sure they last a long time without changing shape or getting old, it is best to pickFood Safe Silicone Tubing tubes that can handle temperatures exceeding 230 °C.
The wall of the pipe should be the right thickness.
If the steam oven's internal pressure is too high, the thin tube wall may stretch or even break. In most cases, a silicone tube with walls that are 1.5 to 3 mm thick would work.
Stay away from sharp bends
Even though silicone tubing is soft, bending it sharply over time can produce cracks. To make sure that steam flows smoothly, it is best to keep the bending radius greater than double the diameter of the pipe during installation
四, Food-grade silicone tubing is often used in steam ovens.
Link between the heater and the water tank
You can use silicone tubing to link water tanks to heaters. This will guide the water flow and make steam.
Pipeline for steam exhaust or circulation
Silicone tubing is utilized as a steam delivery pipe in the steam cycle system to make sure that high-temperature steam flows smoothly.
drainage pipe
Some steam ovens can drain water, and you can use food-grade silicone hoses to do this.
Sealed interface
You can use soft silicone tubing to seal the interface, stop steam from leaking, and keep the oven running smoothly.
Silicone tubing makes ensuring that steam ovens are safe, work well, and stay clean by using these applications.
五, Tips for buying food-grade silicone tubing
Pick pipe materials that have been approved
To keep toxic substances from moving, make sure the pipes meet food safety requirements like FDA, LFGB, or GB 4806.
Check the standards for temperature resistance
The temperature resistance should be higher than the steam oven's highest operating temperature. In general, you should choose a temperature resistance of at least 230 °C.
Pay attention to the size of the pipe and the thickness of the wall.
The pipe's diameter should fit the steam oven's opening, and the walls should be thick enough to handle pressure without making the pipe less flexible.
