Extrusion Feeding
Vol. 26 #2, September 1999
A key to successful extrusion is feeding the correct ingredients in the proper amounts. Things to consider include the following:
- selecting proper feeders, loss-in-weight or volumetric
- calibrating feeders for the ingredient or load cell weight
- pre-blending or separating feed ingredients
- understanding the interaction of hopper fill level and rate accuracy
- verifying the right ingredients are used and are readily available
Write to the newsletter editor, if you would like an in-depth coverage of any of these subjects in a future newsletter.
