Page 6 Focus on Feeders This gravimetric enrobing feeder provides a high ratio of base and additives at your enrobing process. Feeding additives by weight provides excellent control of the dispensing of these ingredients. Page 17 Errant Feeder Operation and Possible Solutions It is quite common to encounter flow problems in various types of equipment for feeding dry solids. These problems can be constant and unpredictable, and so they can also be costly. Page 18 USDA-Accepted Airsweep This new line of USDA-accepted Airsweep pneumatic nozzles is designed for promoting on- demand flow of bulk material and reducing flushing/cleaning time between batches. The new Airsweep was developed specifically for use in sanitary process environments. It is designed to deliver quick, powerful, pulses of compressed air or gas along the inside walls of process equipment or vessels, followed by an instant re-seal to eliminate material feedback. Sanitary design and fabrication principles are incorporated to meet the stringent USDA guidelines.
