PE PA and PP corrugated hose look the same but quite different from each other
In the food industry, there are various hoses. These hoses play an important role in food deliver, mixing, storage and other aspects. However, different food hose materials have various features. Thus correct selection of the right hose is crucial to ensuring food safety. In general, most of the food grade pipe materials are plastic and rubber. Then next, let me introduce you some common used food hoses.
EPDM food hose
EPDM hose has good heat resistance, ozone resistance and chemical corrosion resistance. Can be used in the temperature range of -40℃ to 150℃. EPDM hose is ideal for the food with high temp and high pH. Such as lemon juice, grape juice, etc. At the same time, EPDM hose is flexible and compression resistant. Therefore, it can reduce the wear and tear of food and ensure the quality of food.
Nitrile rubber food grade hose
NBR rubber pipe has excellent oil, wear and aging resistance. It can work at -20℃-100℃. NBR rubber pipe is ideal for various oils like cooking oil, lubricant, etc. However, it should be noted that NBR rubber pipes are not suitable for transporting foods with high temperature and high pH.
UPE food safe hose
UPE hose has excellent wear and corrosion resistance. It can work at -20℃-80℃. UPE hose is ideal for granular and powdery foods such as sugar, salt, flour, etc. The anti-stick property can reduce the caking of food. Therefore, the use of UPE hoses can ensure the quality and taste of food.
PTFE food grade hose
PTFE hose is also know as Teflon hose. It has excellent heat and corrosion resistance with low friction coefficient. Besides, it can work at high and low temp from -200℃ to 260℃. PTFE hose is ideal for the food with high temp and high pH. Such as baked goods, chocolate, etc. At the same time, PTFE hose has excellent chemical stability. Therefore, it can resist the erosion of various chemicals and ensure food safety.
