3-A SSI Announces Development of New Standard for Rotary Airlock Valves

3-A SSI Announces Development of New Standard for Rotary Airlock Valves

3-A SSI invites participation in a Working Group to draft a new 3-A Sanitary Standard for rotary airlock valves. Formation of the new Conveyors & Feeders Working Group follows approval by the 3-A SSI Steering Committee to initiate the new project based on requests from manufacturers of rotary airlock valves. The proposed new standard will apply to the sanitary aspects of rotary airlock valves used to feed product at a controlled rate and/or feed product across a pressure differential while acting as an airlock.  Rotary airlock valves are rotating devices used to dispense products with solids or particulates from vessels that isolate the vessel from the equipment the product is discharged into. Any integral tubing and fittings used for feeding product from the rotary valve into a pneumatic convey system, or venting air from the rotary valve, included with the rotary valve from the manufacture shall be included within the scope of this standard. Food and beverage suppliers outside the dairy industry should be particularly interested in participating as many of them handle powders that are transferred by vacuum through rotary airlock valves. Other processors include but are not limited to Produce, confectionery, dry goods, grains.

Participation on 3-A SSI Working Groups is open to all persons who are directly and materially affected by the development of this new proposed standard. A current copy of all Working Group rosters may be found by visiting the Working Group webpage: including project status, Procedures, Working Group Sign-Up Form and more.
