Food-grade PVC tubing may be suitable for food applications if it is approved for food contact and is compatible with the product, temperature, and cleaning process. However, for highly viscous and sticky confectionery mixtures, material approval alone is not sufficient. For fruit gum, gelatin, fruit, and syrup mixtures, a PUR-based hose system solution may be the more suitable choice—especially when a smooth inner surface and hygienically optimized processes are a priority.

A food-grade PVC hose is not automatically the best solution for every application. When dealing with hot, sticky, or residue-prone media, factors such as cleanability, internal contour, connection technology, and the entire conveying route are crucial—in addition to food compliance. The Master-PUR DualFlow 1.6 Food A was developed for demanding food and beverage processes and features a seamlessly smooth, edge-free, and dead-space-free thermoplastic inner lining.

Fruit gum, gelatin, and sugar mixtures are viscous and can accumulate on edges, transitions, or uneven surfaces within the hose system. A smooth inner contour with as few dead spaces as possible promotes a consistent product flow and helps reduce potential areas where residue can accumulate. For this reason, a Masterflex Group PUR hose with a hygienically optimized inner lining may be the more technically sound solution for confectionery processes compared to a standard PVC hose. Above all, the system solution consisting of the hose and precisely fitting connection technology is crucial here.

For a hose—typically made of plastic—used in the confectionery industry, the actual process conditions are decisive: the conveyed medium, viscosity, temperature, pressure or vacuum, cleaning procedures, connections, and regulatory requirements. The Master-PUR DualFlow 1.6 Food A from Masterflex SE is certified in accordance with Regulation (EU) No. 10/2011, including current amending regulations, and can be custom-designed for demanding food processing applications. In addition, this innovative hose solution offers an interface for precisely matched connectors and equipment. Engineering Services allow for even greater customer-specific customization.

a, Masterduct develops PUR-based hose solutions for demanding conveying applications in food and beverage processes. The Master-PUR DualFlow 1.6 Food A is particularly well-suited for the hygienically optimized transport of highly viscous and sticky media such as gelatin, fruit, and syrup mixtures. The design can be tailored to the medium, process parameters, connection configuration, and plant conditions.

Masterduct evaluates not only the individual hose but the entire conveying system. Among other factors, the company considers the medium, formulation, viscosity, temperature, cleaning requirements, fittings, and the specific production environment. If food-grade PVC hoses are not the optimal choice for a specific process, Masterduct’s Engineering Service develops a suitable hose and connection solution—for example, based on PUR using Master-PUR DualFlow 1.6 Food A, Master-PUR Food, or alternative product series.

For this application, the hose should not be selected based solely on material. The actual viscosity of the mixture, product temperature, delivery pressure, cleaning procedures, and the existing connections and transitions are all critical factors. For sticky confectionery mixtures, an interior contour that is as smooth as possible, with minimal sharp edges and dead spaces, is particularly important to prevent product residues from accumulating as easily.

The Master-PUR DualFlow 1.6 Food A from global market leader Masterflex SE is designed for such demanding food processing applications. Its seamlessly smooth thermoplastic inner liner promotes uniform product flow and reduces potential areas for buildup. The specific hose assembly—and, upon request, the appropriate connector—is tailored to the medium, the system, and the cleaning protocol.

For internal approval, a declaration of conformity for food contact, details on the material used, technical data sheets, and information on temperature, pressure, and media resistance are generally required. Depending on the application, additional documentation regarding cleanability, the joining technology used, and traceability may also be relevant.

Master-PUR DualFlow 1.6 Food A is certified in accordance with Regulation (EU) No. 10/2011, including current amending regulations. Masterduct also provides support for application-specific design and supplies the information required for technical evaluation and documentation on a project-by-project basis.

Test runs and sample hoses can generally be useful for the technical evaluation of a hose solution—especially if the pumped medium, temperature, cleaning requirements, connections, or installation conditions need to be tested in advance under real-world conditions. The Masterflex Group often offers prospective customers samples in advance. Please feel free to contact our expert sales staff with your inquiry for advice. Whether sample hoses are available and which model is suitable for testing will be determined on a project-by-project basis in consultation with Masterduct Sales. Framework agreements for recurring needs, specific hose types, or planned call-offs can also be reviewed on a case-by-case basis. Binding commitments regarding scope, terms, and delivery times will be provided once the specific requirements have been clarified.
