News - Food Suction & Delivery Hose – EPDM Construction for Harsh Food-Grade Conveying Scenarios

In the daily production of food and beverage factories, transporting raw milk, fruit juice, beer and cooking oil puts strict requirements on hose sanitation and operational stability. These pipelines need to survive frequent high-temperature onsite cleaning, stay unaffected by oily and acidic raw materials, and adapt to fluctuating working temperatures. This newly developed food suction and delivery hose adopts FDA-certified white EPDM inner liner, multi-layer polyester fabric plus spiral steel wire reinforcement and weatherproof blue EPDM outer skin, tailored to solve tough medium transfer challenges in food production sites.

Three Core Design Advantages

White EPDM Inner Tube: Stable material, no medium contamination, easy onsite cleaning

The white EPDM inner lining meets FDA 21 CFR 177.2600 standard. Thanks to its stable chemical property, it won’t bleed peculiar smell, pigment or foreign taste into flowing food media, a key feature for dairy, beer and edible oil production. Smooth inner bore greatly lowers bacteria buildup and avoids grease and acid permeation into hose wall. Besides, EPDM material stands repeated CIP online hot water and detergent cleaning work, cutting factory cleaning waiting time and avoiding cross-contamination of different production batches caused by residual substances.
Multi-layer Fabric + Spiral Steel Wire: Stable pressure resistance, anti-collapse under full vacuum

High-strength polyester fabric laminated together with embedded spiral steel wire enables the hose to hold 10 bar working pressure, with 30 bar burst pressure at 3:1 safety coefficient. Built-in spiral steel wire effectively prevents tube shrinkage and collapse under negative pressure, fitting tanker milk unloading and large tank juice pumping suction conditions perfectly.
Blue EPDM Outer Cover: Anti-wear, anti-ozone and outdoor aging resistance

Wrapped-type blue EPDM outer sheath is specially compounded to fend off ozone erosion, ultraviolet aging and frequent friction wear. Even after long-term outdoor placement or repeated dragging on rough factory ground, the hose keeps soft without cracking. The distinct blue appearance also helps field workers quickly distinguish food-grade pipeline from other industrial hoses in cluttered production workshops.

Wide applicable temperature range to match diversified global production

Service temperature spans from -40°C to 100°C, covering low-temperature cold storage transportation and high-temperature filling lines for pasteurized milk, hot fruit juice and hot edible oil.

Common conventional specifications

The smallest inner diameter 19mm (3/4 inch) weighs roughly 0.67kg per meter, mostly used for dairy sampling and small-batch raw material transfer. The 25mm (1 inch) specification is a mainstream choice for brewery material unloading. Sizes of 51mm (2 inch) and 76mm (3 inch) are widely arranged on main production pipelines to guarantee stable medium flow and convenient installation. Max size reaches inner diameter 152mm (6 inch), standard delivery length 30 meters with unit weight 8.17kg per meter, designed for large-flow bulk edible oil and raw water suction. All specifications keep uniform 10 bar working pressure, fixed 3:1 safety ratio and -40℃~100℃ working temperature.

Material comparison: Why pick EPDM for rigorous food transfer?

Multiple rubber materials can be manufactured into food delivery hoses with respective pros. PVC hose is lightweight and cost-efficient, ideal for normal-temperature clean water and dry granular goods conveying. NBR nitrile rubber boasts outstanding oil resistance and matches partial high-oil-content food delivery. SBR rubber features good wear performance for general food conveying. Our EPDM food suction hose focuses on high heat resistance up to 100°C, strong tolerance against animal and plant grease, outstanding anti-UV and anti-ozone performance as well as full vacuum resistance. It’s not an all-purpose substitute for other rubber hoses, but targeted for severe working conditions in food processing workshops.

Summary

This EPDM suction hose is a practical option for dairy factories, breweries, juice and edible oil manufacturers that run regular high-temperature, high-oil or acidic medium transfer and frequent field washing work, balancing long service lifespan and strict food safety standards.
