What properties should a fire hose has
Food-grade hose refers to a hose that meets food hygiene and safety standards and can be used in food processing, transportation, storage and other links. The following are some common food-grade hoses:
Food grade silicone hose
It has excellent high temperature resistance. It can be used for a long time in the temperature range of -60℃ to 200℃. In addition, it is highly soft, elastic, and not easy to age or crack. Therefore, it can adapt to different installation environments and complex bending requirements. At the same time, silicone hose is non-toxic and tasteless and meets food hygiene standards. It does not pollute food in any way. And it does not affect the taste and quality of food.
Strong chemical corrosion resistance. It can resist the erosion of most acids, alkalis, salts and other chemical substances. Therefore, it is suitable for conveying food materials of various properties. It is commonly used in food and beverage filling production lines, liquid medicine delivery in the pharmaceutical industry, etc.
Food grade PVC hose
It has good transparency and can clearly observe the flow of food materials in the tube.
The price is relatively low and cost-effective. It is soft and light, easy to install and carry. But its use temperature range is relatively narrow, generally between -15℃ and 60℃. It is mainly used for liquid material transportation in food processing, such as filling pipes for beverages, soy sauce, vinegar, etc.
Food grade rubber hose
Made of natural rubber or synthetic rubber, it has good flexibility and wear resistance.
It has good oil resistance and water resistance, and can withstand the transportation of food liquids or semi-fluids under a certain pressure.
It has good sealing performance to prevent food material leakage.
However, the aging resistance of natural rubber hose is relatively weak. The performance of synthetic rubber hose varies according to different formulas. It is often used for material transportation in food processing, such as edible oil, honey, etc. It can also be used for connecting pipes of some food processing equipment.
