Abstract
Disclosed is a sanitary acoustic horn for use in the dairy industry for preventing powder build-up in dairy industry drying systems and for meeting U.S.D.A. requirements for equipment which comes in contact with powder product. The sanitary acoustic horn includes a driver and a bell connected to one another by means of sanitary ferrules and quick connect hinged clamps. The sanitary acoustic horn is preferably made from 304 stainless steel and having at least a number 4 finish on all surfaces which will be exposed to powder product. A number 4 finish inhibits the collection of powder on such surfaces by eliminating pits, scratches, grooves and the like therefrom. The quick connect clamp allows for easy assembly and disassembly of the horn for a manual cleaning. The sanitary horn further includes an air delivery chamber which extends about the driver. Such air delivery chamber has sufficient dimension to allow insertion of human fingers and cloths so that such surfaces may be easily cleaned. Further, all corners of the equipment which will come in contact with powder product are ground and polished to a minimum 1/4' radius or, at least, to a minimum radius equal to the thickness of the material.
