PNEUMATIC
IN-LINE SCREENERS
Introducing
the recently improved Pneumatic In-Line Screener. The
In-Line Screener operates in positive or negative
atmospheres, eliminating compressors, airlocks, collectors
and receiving hoppers enabling direct insertion into bulk
carriers, storage bins and process pneumatic systems.

With our
recent improvements, Gump In-Line Screeners are simpler to
install, operate, and maintain. These improvements include: a hinged cover for faster
and easier opening; new, adhesive free, single piece
gaskets; new single point locking for faster and easier
inspection of internals; and a horizontal product discharge
for tight installations. We also offer optional light
weight ABS plastic (food grade) sieve frames.

PRINCIPLES
OF OPERATION
As the
schematic illustrates: air and product enter at high
velocity at A where it is divided into two streams by
the deflector B. The velocity of the air is reduced
to 1/64 of its input speed. This reduction in velocity
permits the product in suspension to fall into the screening
surface below. Most of the air takes the path of least
resistance up through screen D, which screens air and
prevents unwanted particles from entering the air stream.
The air travels through air bypass G and down through
final outlet P, re-entraining with the screened
product. The air bypass configuration G assures an
equal or balanced pressure above and below each screen at
all times and under all conditions of loading. Material is
moved across the screen by rotary motion. Particles
smaller than the screen openings fall through the screen and
are carried down tray F to outlet G.
Material larger than screen openings and excess materials
containing both fine and course products pass over and under
weir E. This material then falls into second
screen H through outlet C. This process is
then repeated and screened product exits to outlet G
from tray J. The third screening is handled in
a similar manner by screen M where the process is
repeated and screened product exits to outlet P.
Overs exit outlet O.

PACKAGED
MIX PLANT
Screens sugar,
flour and spices prior to weighing, mixing and
bagging. Mixing system using two CP-32 Screeners is
operating at 20,000 lbs/hr through 20 mesh stainless steel
bolting cloth.

SOUP MIX PLANT
Unloads flours and
starches through a CP-43 at up to 40,000 lbs/hr to storage
bins. Transfers from storage bins to use bins through
a second CP-43 at up to 40,000 lbs/hr. A third CP-43 screens
starches and flours Durum and soft, low grades en route to
scale.
