一,. The physical properties of silicone hose
Silicone hose is a flexible pipe consisting mostly of silicone rubber. It has a lot of unique features that make it useful in a wide range of industrial, medicinal, and food and drink equipment.
1.1 Performance at high temperatures
Silicone hoses can handle high temperatures, which is one of their best features. Standard silicone hoses can handle temperatures between -60 ° C and +200 ° C. High-performance silicone hoses can handle even greater temperatures. This is especially critical for coffee makers because the hot water inside them is normally between 85 and 95 degrees Celsius
1.2 Stability of chemicals
Silicone hoses don't react with chemicals like water, coffee, or acidic or alkaline substances. This means it won't let out dangerous chemicals and won't change the taste or smell of coffee. This is very important for the food and drink business because any movement of chemicals might affect people's health.
1.3 Stretchiness and Flexibility
The silicone hose is flexible and stretchy, which makes it easier to bend and fit into the coffee machine's complicated water system. The waterway design of a coffee machine, whether it's a tiny one for the family or a big one for business, is usually compact,
1.4 Resistance to voltage and ageing
A good silicone hose can handle extreme temperatures, some water pressure, and it doesn't age. It is hard to break, harden, or leak even when it is in hot water for a lengthy time. This makes sure that the coffee machine will work well for a long time.
二, How safe food-grade silicone hoses are
Because coffee machines touch both drinking water and coffee liquids directly, the hoses used must meet food safety regulations. Regular industrial silicone may have leftover chemicals or additives in it, thus it shouldn't be used in drinking water systems.
2.1 Standards for food grade
certification Most of the time, food grade silicone hoses have to meet these international standards:RoHS and REACH standards limit the use of dangerous chemicals to protect the environment.These guidelines mean that silicone hoses can be safely used in the water and steam systems of coffee machines.
2.2 No smell and easy to clean
Food-grade silicone hose that is of high quality has no smell and won't change the smell of coffee. And silicone can handle cleaning at high temperatures and steam disinfection, which is highly crucial for keeping coffee equipment clean and safe.
三, How silicone hoses are used in coffee machines
Silicone hoses can be used in many important parts of coffee makers, such as delivering hot water, connecting the water tank, and more.
3.1 A mechanism for delivering hot water
The heater transports hot water from the water tank to the coffee outlet. This means that the hose needs to be able to handle high temperatures and pressures. Silicone hoses can safely carry hot water
3.2 Pipeline for steam
Italian coffee machines employ very hot steam to make milk froth, which can damage or break regular plastic hoses. Silicone hose is the best choice since it can handle high temperatures, is very flexible, and can handle steam pressure.
四,. Things to keep in mind when utilising silicone hoses
Even though silicone hoses work quite well, you should nevertheless take the following safety steps when using them in coffee machines:
4.1 Make sure the standards for food grade are met
To keep dangerous compounds from moving from regular industrial silicone to drinking water or coffee, food-grade silicone hoses must be used.
4.2 Regular checks and replacements
Silicone hoses can get a little older or harder after being used for a long time. To make sure the water is clean and the equipment is safe, they should be checked and updated often.
4.3 Reasonable installation
When installing the hose, you should avoid bending, compressing, or stretching it too much. Instead, let it bend naturally and use set clamps to keep water from leaking.
五,. Examples of how silicone hoses are used in different kinds of coffee machines
5.1 Drip coffee maker for home use
The water temperature in the drip coffee maker is not very high, but it is still important to make sure that the water circuit is clean and safe. You can use food-grade silicone hoses to connect pipelines between water tanks and heaters. This makes sure they last and are clean.
5.2 Italian coffee maker for home or business
Italian coffee machines need steam and hot water lines that can handle high temperatures. Silicone hoses can bend and don't melt, so they can be used in steam and hot water pipes. This keeps the coffee and milk foam quality high.
5.3 Coffee maker that works all by itself
There are a lot of pipes in the internal water circuit of the fully automatic coffee machine. Silicone hoses are flexible, easy to bend and install, can fit into tight locations, and can handle long-term use of hot water and steam pressure.
