Foodstuff Hoses and Pharmaceutical Hoses

Applications and Properties

NORRES foodstuff hoses are used in applications involving rice, sugar, milk powder, coffee, tea, cereals, grain and other dry food products. Depending on the selected hose model, applications can include silos, silo vehicles, tank trucks and systems for filling or emptying bulk bags.

These hoses may also be used with packaging machines, mixers and dryers. In pharmaceutical processing, suitable models can be used with vacuum conveyors, suction conveyors, dosing systems and tablet presses.

NORRES identifies products carrying the FOOD designation for suitable food-related applications. According to NORRES, the relevant food-grade hose walls are designed to be taint-free and odourless. The food-grade range also includes properties such as resistance to microbes, hydrolysis, oils and chemicals, depending on the individual hose model.

Models carrying the AS designation are identified as antistatic. This property is especially important when friction between the conveyed material and the hose wall can produce electrostatic charging, including suitable applications involving flammable materials or potentially explosive environments.

Frequently Asked Questions

Q: What products can NORRES foodstuff hoses convey?
A: According to NORRES, suitable models may be used for rice, sugar, milk powder, coffee, tea, cereals, grain and other dry food products. NORRES also states that frozen food products can be conveyed using hoses from this application range.

Q: Can these hoses be used in clean rooms?
A: The NORRES application-area page states that the hoses in this section can be used in clean-room applications. The exact hose must still be checked against the hygiene, food-contact and technical requirements of the individual system.

Q: Which NORRES food hoses are antistatic?
A: Hose models carrying the AS designation in their product name are identified as antistatic. The exact electrical resistance, grounding instructions and installation requirements must be checked in the current technical documentation for the selected model.

Q: Why is antistatic performance important when conveying food ingredients?
A: Friction involving the conveyed material and hose wall can produce electrostatic charging. Where flammable materials or potentially explosive conditions are involved, an appropriately selected and correctly installed antistatic hose can help control this risk.

Q: Are all NORRES foodstuff hoses identical?
A: No. The listed products have different materials, wall thicknesses, reinforcement systems, duty levels, temperature ranges and technical properties. Food-contact approvals and antistatic certifications must be confirmed for the individual model.

Q: Which NORRES hoses are suitable for mixers, dryers and packaging machines?
A: NORRES particularly identifies PROTAPE® PUR-C 335 FOOD-AS FLAT and AIRDUC® PUR-INOX 355 FOOD-AS (HD) for these applications.

Q: How can customers select a suitable NORRES foodstuff or pharmaceutical hose in Malaysia?
A: Customers may contact HUPLONG INDUSTRIES (M) SDN BHD with the conveyed material, required internal diameter, hose length, operating temperature, pressure or vacuum conditions and applicable food-contact, clean-room or antistatic requirements.

Final product selection must be based on the current NORRES product information and technical documentation for the individual hose model.
