TRANSCRIPT
A new era in commercial grain drying
Large wet holding garner bin is sealed to help retain grain dust and bees wings.
Stainless steel, roll formed, exterior sheeting promotes long dryer life and improved dryer appearance.
Heavy-duty overall construction results in an extra rigid struc-ture on a minimum of ground space.
Inside and outside safety ladders, cages and catwalks provide safe and easy access to all areas of the dryer.
Reducer cone equal-izes air velocity past burners for optimum combustion and pro-vides step-in access to burner assembly.
Walk-in heat section provides easy access for interior cleaning.
Recycling heat from the cooling grain results in significant fuel savings.
Walk-in cool sec-tion provides easy access to blowers and metering system.
Patented discharge sys-tem provides simple, uniform metering and quick dryer clean out.
Industrial quality components (includ-ing Maxon valves and burners) ensure years of reliable service.
12” wide grain col-umns and long grain retention times result in high quality, effi-ciently dried grain.
Patented grain turn-ers in each column ensure even drying.
In-line Maxon NPLE series burners pro-vide even heat and efficient combustion from either natu-ral gas or LP vapor (fuel oil burners are optional).
Divider hopper sepa-rates the heating and cooling sections while preventing build-up of particulate matter.
Internally mounted tubular centrifugal blowers deliver high volumetric airflow to the pressure heat and suction cool sections.
Internal mounting provides the added benefit of ultra quiet operation as the sur-rounding grain cre-ates a natural noise barrier.
PLC Control System provides the most advanced and reliable dryer control on the market.
Weather-proof NEMA IV cabinets and NEMA rated electrical compo-nents ensure safe and reliable operation in all conditions.
Discharge area
Cool, dried grain passes from the
cooling section of the dryer into
the sealed, hoppered discharge
section. Grain is gravity fed down
a 45° hopper to GSI’s patented
metering drum. This drum pro-
vides a positive, yet gentle means
of metering grain uniformly from
each column of the dryer and dis-
charging it out the center of the
dryer. The drum is driven by a vari-
able speed inverter operated AC
motor. The hopper bottom design
of the dryer eliminates trouble-
some sweep augers and sweep
arms and provides for quick dryer
clean-out.
Blower(s) anD Burners
Depending on the size of the dryer, one, three, or four indus-
trial duty blowers are used in the GSI Tower Dryer. These inter-
nally mounted, in-line mixed flow blowers are sized to operate
at slow speeds, which means low noise levels, low electrical
usage and long blower and motor life.
Airflow from the blowers is ducted across a Maxon NPLE
line burner. The burner can operate on either natural gas or LP
vapor. The burners are sized and profiled to provide even,
efficient heat distribution to the drying section of the dryer.
“The metering drum is virtually mainte-nance free. You get an even flow with no buildup and stalks are never a problem.”
Computerized operation
electronic Monitoring
GSI’s touch screen control panel
is the most advanced and reliable
dryer control system on the
market. It offers computerized
control of all dryer functions and
self diagnoses dryer problems
eliminating the guesswork
associated with traditional
controllers. The touch screen is
very simple to operate providing
instant information via a large
color display. It calculates total
dryer time, bushels per hour and
total bushels dried. Memory
features in the unit maintain a
history of past dryer operation
and a permanent service record.

The GSI control box is housed
metal NEMA IV enclosure. The win-
dowed design of the box allows
all dryer operations to be viewed
through the lockable windowed
door and also protects all control
switches, indicators, and controls.
For convenience, the control box
can be remote mounted or mount-
ed at the dryer. The control box is
totally computerized using Allen
Bradley industrial controls and com-
municates with the dryer power box
via an DH485 communication link.
Mounted in a large NEMA IV enclosure, all of the electrical power and dryer
monitoring components for the dryer are controlled by an Allen Bradley SLC con-
troller. The electrical layout and wiring of this box is MET laboratories certified,
making the box meet all U.S. and Canadian safety standards. This will provide a
long reliable control system for the dryer.
The GSI Tower Dryer’s electronic control panel indicates any malfunctions via a flashing display. This process saves valuable time in the area of trouble-shooting.
Full Color Graphical Display provides continuous visual feedback on the cur-rent dryer status as well as a convenient means of setting operating param-eters and options. Most set points and status screens are accessed by simply touching an on-screen object.
easY access
The GSI Tower Dryer was
designed with convenience in
mind. Catwalks, ladders and cages
are provided on all areas of the
dryer for easy accessibility. All
areas of the dryer can be eas-
ily accessed through up to
four entry ways. Cleanout,
inspection, and general main-
tenance are never a problem
with the GSI Tower Dryer.

cutting-eDge technologY
Grain Systems, Inc. has a reputa-
tion for engineering excellence.
The Tower Dryer exemplifies this,
with design innovation unmatched
by anyone in the industry.
The Tower Dryer design utilizes
industry proven drying principles
along with many unique fea-
tures to provide the commercial
user with a simple, reliable, fuel
efficient grain dryer. Each dryer
employs a bolt together (versus
welded) design, which permits
the wide use of galvanized steel
(versus painted steel) throughout
the dryer. In addition, all dryers
have stainless steel, roll formed
exterior sheeting as a standard
feature. These design features sim-
plify dryer erection, improve dryer
appearance and promote a long
dryer life.
The hopper bottom design used
on the dryer, including GSI’s pat-
ented metering drum, provides a
simple, efficient grain discharge
system. This system transfers grain
from the dryer uniformly and
allows for easy dryer clean-out.
The touch screen controls offer
computerized control of all dryer
functions. This “smart” system
eliminates guesswork by providing
the operator instant information
on a large backlit color display and
makes the operation of the dryer
simple.

Monticello, Illinois.
froM the top Grain enters the dryer at the top
and falls into a self cleaning grain
receiving chamber. The chamber
creates a grain cushion, and with
grain falling on grain, helps reduce
plenum roof wear. This chamber
also provides a means of distribut-
ing grain evenly around the dryer.
The garner bin at the top of the
dryer has a full 40 inches of wet
grain storage. This area is com-
pletely sealed to help retain grain
dust and particulates.
Grain moves
down, out of the
garner area, and
enters 12” wide
grain drying col-
umns in the heat
section of the dryer.
The GSI Tower Dryer
is designed to pro-
vide the optimum
balance of grain
retention time,
airflow and temperature. Large
column holding capacities result in
long grain retention times in the
drying section of the dryer. This
long retention time, combined

with low drying airflows and tem-
peratures result in high quality,
efficiently dried grain.
Midway down the heat section
of the dryer are GSI’s patented
grain turners. The turners invert
the grain from the inside of the
grain column to the outside for
more uniformly dried grain.
GSI tower dryers are designed
to retain bees wings and particu-
late matter within the drying col-
umns. The largest standard hole
size on the exterior screening of
the dryer is 0.078 inch diameter
perforation. After the grain is
turned, the perforation size drops
to a diameter of 0.0625 inches.
Solid non-perforated exterior
sheets are used at the grain turn-
ers and at the top and bottom of
the grain columns to help ensure
that particulates are not expelled
from the dryer.
As grain exits the heat section
of the dryer it enters the suction
cooling section. Air used to cool
the grain is recycled through the
blower(s) resulting in significant
energy savings.
