                Hoses for food and pharmaceuticals

                Applications and properties

                Due to their properties, foodstuff hoses are suitable for a wide range of uses in the food industry. They are used for the conveying of food such as rice, sugar, coffee, tea or grain in silos, silo vehicles and tankers. They are also frequently used in packaging machines, mixers and dryers for big-bag charging and discharging. Because of their food safe walls and other important properties, these hoses are also suitable for use in the pharmaceutical industry. These include, for example, the use in vacuum conveying devices, suction conveyors, dosing systems and pelleting machines.
                Our foodstuff hoses are odourless and taint-free, resistant to microbes and hydrolysis, and resistant to oils and chemicals. Hose types with the identifier AS are also antistatic, which is very important in the conveyance of flammable goods and the use in hazardous areas.
                The following hose types are particularly suitable for food conveyance: AIRDUC? PUR-INOX 355 FOOD-AS, AIRDUC? PUR-INOX 356 FOOD-AS / PUR 356 FOOD / PUR 356 FOOD REINFORCED, but also BARDUC? PUR-INOX 382 FOOD-AS.
                The PROTAPE? PUR-C 335 FOOD-AS FLAT and the AIRDUC? PUR-INOX 355 FOOD-AS are particularly suitable for use on mixers, dryers and packaging machines.
                The products CP PUR 455 FOOD, PROTAPE? PUR 330 FOOD, PROTAPE? PUR-INOX 330 FOOD-AS, AIRDUC? PUR 350 FOOD-AS / PUR 351 FOOD / PUR-INOX 351 FOOD-AS / PE 362 FOOD and CP PTFE-INOX 475 FOOD can be used as alternatively usable hoses.

                Frequently asked questions

                Which hoses are antistatic and why is this important?

                All hoses bearing the abbreviation AS in the product name, such as the AIRDUC? PUR-INOX 355 FOOD-AS. In the case of hoses which are not antistatic, electro-static charging occurs due to the friction of the material against the wall and the friction within the medium. In the case of flammable raw materials, that can lead to an ignition or even explosion of the raw material. The use of antistatic hoses can prevent this risk.

                Can the hoses be safely used to convey food and be used in clean rooms?

                All hoses in this section can be used in clean rooms and can be safely used for food such as rice, sugar, milk powder, coffee, tea, cereals and other dry foods. Frozen foods can also be conveyed.

                Are these hoses flow-optimized?

                Yes, all specified hoses are flow-optimized due to their geometry and the smooth interiour surface.
