Food hygiene hose: Differences between EPDM hose, NBR rubber hose, UPE hose, and PTFE hose
In the food hygiene industry, various hoses are widely used, and these hoses play an important role in the transportation, mixing, storage and other aspects of food. However, different food hygiene hose materials have different characteristics and applicable scopes. Correctly selecting the right hose is essential to ensure the safety and hygiene of food. The following is an in-depth and detailed discussion of the characteristics of EPDM hoses, NBR rubber hoses, UPE hoses, and PTFE hoses and their applications in the food hygiene industry, in order to provide readers with a reference.
EPDM hoses (ethylene propylene diene monomer rubber hoses) have good heat resistance, ozone resistance, and chemical corrosion resistance, and can be used in a temperature range of -40°C to 150°C. EPDM hoses are often used in the food industry to transport high-temperature, high-pH foods, such as lemon juice, grape juice, etc. At the same time, the EPDM hose has excellent softness and compression resistance, which can effectively reduce the wear of food during transportation and ensure the quality of food.
NBR rubber tube (nitrile rubber tube) has excellent oil resistance, wear resistance and aging resistance, and can be used in the temperature range of -20℃ to 100℃. NBR rubber tube is often used in the food industry to transport edible oil, lubricating oil, etc. Due to its oil resistance, NBR rubber tube is widely used in the food industry, but it should be noted that NBR rubber tube is not suitable for transporting high temperature and high pH food.
UPE hose (ultra-high molecular weight polyethylene hose) has excellent wear resistance, corrosion resistance and anti-sticking properties, and can be used in a temperature range of -20°C to 80°C. UPE hose is often used in the food industry to transport granular and powdered foods such as sugar, salt, flour, etc. The anti-sticking properties of UPE hose effectively reduce the agglomeration of food during transportation and ensure the quality and taste of food.
PTFE hose (polytetrafluoroethylene hose) has excellent heat resistance, corrosion resistance and low friction coefficient, and can be used in the temperature range of -200℃ to 260℃. PTFE hose is often used in the food industry to transport high-temperature, high-pH foods, such as baked goods, chocolate, etc. At the same time, PTFE hose has excellent chemical stability and can effectively resist the erosion of various chemicals to ensure the safety and hygiene of food.
