Using a simple cordless drill, the feeder dispenses most dry bulk materi- als quickly, precisely, and easily. It is ideal for lab adds, minor ingredient adds, and smaller scale batching opera- tions and features an easy-to-clean design. It is construct- ed with all food-grade materials and features a stainless steel screw auger.

Page 16 Transitioning to In-Line Powder Flowability Measurement This article considers the requirements for powder flowability measurement, introducing in-line technology that deliv- ers data that are closely comparable to those produced by dynamic powder testing. Page 26 The Reason for and Prevention of Bulk Bag Overhang Because bulk bags are flexible packages, proper design and use are vitally impor- tant. Design decisions need to be based on the physics of the packaging type. Page 36 Digital Weight Indicator Ideal for potentially explosive and hazardous environments, the 882IS intrinsically safe digital weight indicator has FM, IECEx, and ATEX approvals. A stainless steel IP66 enclosure protects this indicator in a variety of applications, includ- ing fuel refineries, chemical plants, distilleries, and textile manufacturing. The 882IS has an optional safe area I/O module for remote communication with peripheral devices such as printers and computers. An auto-ranging power supply allows for a single AC power line to the 882IS, while a rechargeable battery powers four 350-ohm load cells for up to 60 hours.
