Vibra
Screw, Inc., a leading manufacturer of equipment and systems
for precision processing of dry bulk materials, is offering
a new Case History No. C-269 describing how a major snack food
manufacturer uses Loss-in-Weight Feeders to control line dispersion
in production of corn-based products.
The manufacturer had been adding a small but precise amount
of lime to the kettle feed stream by hand to soften and remove
skins from corn kernels prior to processing and cooking. Since
lime tends to settle and not stay suspended, the manual operation
resulted in lumping and balling in the kettle along with wide
accuracy fluctuations in a process that requires extremely
critical ratios of lime to corn.
Vibra Screw’s feed system incorporates a loss-in-weight
screw feeder with a vibrated hopper, horizontal flexible screw
auger and PLC controls for loss-in-weight operation. The system
intermittently feeds 50 lbs. of lime to approximately 300 lbs.
of corn per batch usually twice per hour for approximately
four minutes per batch – a small but evenly distributed
amount of lime. With each corn kernel evenly coated in the
feed stream, lumping and lime settling have been completely
eliminated.
Vibra Screw introduced the concept of controlled vibration
to condition and drive bulk materials into and through a process
more than 40 years ago. Today they manufacture the broadest
line of equipment incorporating this feature including bin
activators, bulk bag
unloaders, volumetric
screw and belt feeders, and all types of graimetric feeds, blenders,
and controls.
