Hygienic Hose for Drinks Processing

In breweries, distilleries and soft drink plants, hose assemblies sit at critical points in every process line, from raw ingredient transfer through to filling. Choosing a hygienic hose for drinks processing is essential to protect flavour, carbonation, clarity, and shelf life, as well as meeting retailer and regulatory expectations. Before specifying or re‑using any line, it is also important to understand how to check if a hose is food safe, so that only compliant, food‑contact approved hoses are ever put into direct contact with drinkable products.

Flextech designs and manufactures food and beverage hoses and assemblies for alcohol and soft drinks applications, helping you match hose materials and couplings to specific media, temperatures and cleaning regimes.

What makes a hose hygienic in beverage production?

A hygienic hose must do more than simply carry liquid from A to B. In drinks processing, key characteristics include:​

• Smooth, non‑porous liners that minimise product hold‑up and support effective CIP.
• Odourless and tasteless inner tubes that preserve the flavour and aroma of beer, wine, spirits, and soft drinks.
• Compounds tested and approved for food‑contact use under UK, EU, and international regulations.
• Correctly specified hygienic end connections and crimping to reduce crevices and dead legs.

Flextech’s hose designs for regulated food and drink duties are engineered around these requirements, with constructions tailored to the different duties found in beverage plants.

Typical hose duties in drinks processing

Within a production site, you will often need several types of hygienic hoses, even when all are handling drinkable products. Common examples include:​

• Raw material transfer: Moving wort, must, juice, syrups, and sugar solutions between vessels.
• Fermentation and conditioning: Connecting tanks, manifolds, and filtration systems.
• CIP and washdown: Delivering hot water, steam, and cleaning solutions to tanks, lines, and floors.
• Bulk intake and Out loading: Tanker loading and unloading of beer, juice, wine, and ethanol.
• Packaging: Feeding filling machines for bottles, cans, kegs, and bag‑in‑box formats.

Each duty places different demands on hose materials, pressure ratings, flexibility, and coupling design, which is why Flextech offers a broad portfolio of beverage-grade hoses and assemblies.

Matching hose material to drink type

The choice of liner and cover material is critical for hygienic performance and long service life. Flextech’s ranges illustrate how different compounds are matched to specific drink types.​

• EPDM rubber: Multiflex and other EPDM hoses are widely used for beer and soft drink transfer where resistance to hot media and common cleaning chemicals is important.
• Butyl Rubber: specialised material designed for the transfer of beer, cider and wines.
• Nitrile Rubber: designed for the transport of Dairy and other fatty based food products
• PTFE: PTFE-lined hoses can be used in processes where high percentage alcohols are being used, such as Ethanol and can ensure hose assemblies are ATEX compliant to ensure Health and Safety regulations are being adhered to.
• Silicone: High‑purity silicone hoses support high‑temperature duties and are used where low extractables and flexibility are critical, including for certain beverage and pharma processes.​​

When specifying a hygienic hose for drinks processing, ensure the compound is explicitly described as suitable for your media and cleaning chemistry in the manufacturer’s datasheet.

Approvals and standards for beverage hoses

Beverage producers must be confident that every hose in contact with the product meets relevant food‑contact legislation. Flextech’s food grade hoses can be supplied to meet standards such as:​​

• FDA 21 CFR 177.2600 for Rubber and 177.1550 for PTFE liners.
• CE 1935/2004 and EU 10/2011 for materials intended to contact food.​
• BfR recommendations, NSF 51 and 61, and 3‑A Sanitary, where appropriate.​
• USP Class VI and EU Pharmacopoeia for specialised high-purity applications.​

These approvals give assurance that, when operated within stated limits, the hose will not impart taste, colour, or odour to drinks or release harmful substances into the product. For broader context on managing food safety and allergen risk within beverage operations, it can be helpful to review official allergen guidance for food businesses alongside your hose specifications and hygiene procedures.

Importance of hygienic couplings and assemblies

Even the best hose liner can be undermined by unsuitable fittings. A hygienic hose assembly for drinks processing should use connection types and crimping methods that minimise areas where product can stagnate.​​

Flextech manufactures assemblies with:​

• RJT, DIN, SMS, and Tri‑Clamp hygienic connections to integrate with brewery and beverage plant standards.
• Dairy fittings and Camlocks for tanker and transfer applications.
• Precisely crimped ferrules designed to give a flush transition between the hose liner and the fitting bore.

Flextech notes that assemblies can be supplied in custom lengths, with appropriate couplings and options such as labelling and hose management tagging to support asset control and auditability. This is particularly valuable where multiple similar hoses operate across a beverage site.

Operating conditions, CIP and steam

In drinks processing, hoses are frequently exposed to hot product, CIP solutions, and occasionally steam. Ensuring hygienic performance, therefore, means keeping within the temperature and pressure ratings stated for each hose.​

Consider the following when choosing and auditing hoses:

• Temperature: Many Flextech food and beverage hoses are designed to handle elevated product and cleaning temperatures, while Steamflex and FDA washdown hoses are intended for hot water and steam washdown.
• Pressure and vacuum: Hoses used on pump discharge, filtration skid connections, and tanker transfer must meet the working pressure and any vacuum conditions with appropriate safety margins.
• Cleaning chemistry: Compatibility with alkaline and acid CIP chemicals, disinfectants, and sanitisers must match the compounds used on your site, including concentration and exposure time.

Running a hose beyond these parameters can lead to swelling, cracking, or premature failure, increasing the risk of leaks and product contamination.

Hose management and audit readiness

Beverage producers face regular audits from brand owners, retailers, and regulators. Demonstrating control over hygienic hoses forms part of that picture.

Flextech supports this by offering hose assembly pressure testing, certification, and hose asset management services. Assemblies can be supplied with documentation and tagging that records specifications, test status, and location, making it easier to manage periodic inspections and planned replacement.​

Integrating hygienic hose assemblies into a structured hose management programme helps reduce unplanned downtime, supports consistent product quality and provides clear evidence during audits.

Selecting the right hygienic hose for your drinks process

When reviewing existing lines or planning a new installation, it helps to work through a simple checklist:​

• Confirm media type: beer, cider, wine, spirits, carbonated soft drinks, syrups, or CIP chemicals.
• Verify operating pressure, vacuum, and temperature for both product and cleaning cycles.
• Identify required approvals for your markets and customers.
• Match hose materials and construction to these conditions.
• Specify hygienic fittings compatible with your plant's standard.
• Decide how you will manage inspection, testing, and replacement intervals.

Flextech’s application specialists use the same factors when recommending hoses and assemblies, drawing on a wide range of Rubber, PTFE, and Silicone solutions from the food grade hoses portfolio. In many beverage plants, this technical selection is also combined with colour coding hygienic process hoses so that product, CIP, and chemical lines are immediately distinguishable on the shop floor and easier to control during audits.
