METALLIC SMS UNION FITTED FOOD, MILK AND DAIRY HOSE PIPES

SPECIAL FEATURES OF A MILK AND DAIRY HOSE

Since milk and dairy hose must comply to FDA & EU standards, special attention is required for its maintenance. The following considerations must be taken into account during hose maintenance.

RESISTANT TO STANDARD CLEANING AGENTS

Milk and dairy hoses are impervious (not affected by) to standard cleaning agents like acid/alkalis and chlorine compounds. Generally, an alkaline cleaner or a chlorinated cleaner is used to clean these hoses. The alkalis, phosphates, wetting and chelating agents in alkaline cleaner dissolves milk fats, protein and carbohydrates. Additionally, the chlorine prevents the formation of films. Acid rinse is also performed to remove mineral deposits from the milk.

STERILIZING WITH STEAM

Steam is the most effective way of sterilizing dairy hoses and equipment. Ideally, the hoses will be exposed to steam for 20-30 minutes. The steam will destroy bacteria and other contaminants and the heat subsequently makes the equipment dry. The temperature and pressure of the steam, however, depends upon the material of the hose.

FITTINGS & ACCESSORIES

To connect the hoses to additional dairy equipment, fittings are used. The specifications for fitting should be considered thoroughly to ensure perfect fabrication, no contamination and a longer service life. The fittings for food grade hoses should also meet FDA food approval. FDA approved fitting materials used in dairy industry includes:

  • Type 303/302 Stainless Steel
  • Type 304 Stainless Steel
  • Type 316 Stainless Steel
  • EPDM

Common fitting types used are:

  • Slotted nuts (Figure 3 left)
  • Linear hose fittings (Figure 3 middle)
  • Hose thread fittings (Figure 3 right)

Milk and dairy hoses are common parts of modern dairy farms as they are used in milking machinery for harvesting milk from animals. They are also used in the dairy industry for conveying milk and dairy products from one part of the plant to another. These hoses are specially made to conform to FDA & EU standards to ensure proper sanitation, milk quality and to avoid chemical contamination. The hose material may include PVC (Polyvinyl Chloride), EPDM (Ethylene Propylene Diene Monomer), hybrid PVC-rubber or NBR (Nitrile Rubber). The rubber inner material makes these hoses resistant to dietary oils/fats. Usually, these hoses are reinforced with coils and an abrasion resistant outer layer to ensure longevity. Figure 1 is an example of a milk and dairy hose.

DESIGN

Milk and dairy hoses are specifically designed for transporting milk and dairy products, as well as for animal and vegetable oils and fats. When hose flexibility is important, like in a milk parlor (a cow milking area), PVC hoses are generally used. A Hybrid PVC-Rubber hose increases the temperature and pressure operating range. The temperature and pressure for the hose is dependent upon the industrial requirement, application and operating environment. Generally, the service temperature of dairy and milk hoses may vary from -40°C to 120°C (-40°F to +248°F). The tube is generally white and smooth and must comply to FDA rules. To increase durability the tubes are often reinforced with stainless steel helix wire.

MATERIAL CONSIDERATIONS

Metalic, PVC, EPDM, hybrid PVC-rubber or NBR are generally used for food grade hose materials. However, following criteria should be considered while selecting the material for milk and dairy hoses.
