FEATURE: GRAIN STORAGE AND HANDLING PROJECTS

pliers said a common trend is toward
larger projects. One reason, they said, is
the instability of grain prices. In the CIS
region, facilities must have the ability to
clean and dry large quantities of grain
since there is very little on-farm storage,
one supplier said.
“Elevators there generally have very
large capacities with relatively low capacity handling equipment when compared with North American-style construction,” the supplier said.
Another supplier said it has recently
built a number of 32-meter-diameter silos. Generally, the uncertainty of cereal
supply throughout the world has been a
major factor when considering additional silo storage, the supplier said. Cost is
also a factor in the trend toward larger
storage facilities.
“The foundation costs and civil works
are a large percentage of the overall
project price,” one supplier said. “With
this in mind, customers are attempting
to achieve economies of scale by building very large 50,000-tonne-plus elevators with large silos and multiple receiving and load-out areas.”
Customers have a growing awareness
of energy efﬁciency and are asking for
simple, effective solutions.
The following is a sample of projects completed in recent months involving some of the world’s biggest
manufacturers of grain storage and
handling equipment.
GRAIN PUMP LOOP
SYSTEM REDUCES COSTS
At the beginning of 2010, the
Ascension Cooperative planned the construction of a storage facility with 28,300
tonnes of storage capacity in Ascension,
Buenos Aires, Argentina. In an effort to
reduce the cost of the handling equipment as well as the cost of the civil
works, the cooperative’s technical advisor, Ingenieria Post Cosecha (IPC), proposed a facility based on the use of Grand
Island, Nebraska, U.S.-based Global
Industries Inc.’s Hutchinson Grain Pump
Loop System.
Ascension Cooperative started the

expansion of its storage facility based
on the IPC design. As a result the cooperative was able to avoid the construction of concrete tunnels below the
silos and the installation of metallic
catwalks to support the entire cross and
longitudinal loops.
To avoid the construction of trenches
at the foundation bases of the silos, the
ﬂat-bottom silos were supplied with
full perforated ﬂoors. IPC developed a
low-cost, ring-style silo foundation base
with a full ﬂat concrete ﬂoor. The longitudinal loops were installed between
the concrete ﬂoor and the full perforated
ﬂoor. All of this resulted in an important
reduction of the total investment as well
as less construction time to build the silos foundation bases and to install the
longitudinal Grain Pump Loops.
The facility started its operation in
2012 and includes two MFS silos Model
S72-17 with side draws, six MFS silos Model S60-15 and Brownie Spiral
Stairs, peak walk around and roof ladder
handrail packages.
Each Model S72-17 MFS silo has 5,007
tonnes of capacity and is 21.94 meters in
diameter, 13.82 meters tall at the eaves
and 19.81 meters high at the peak. Each
Model S60-15 MFS silo has a 3,048-tonne

storage capacity and is 18.29 meters in diameter, 12.19 meters tall at the eaves and
17.06 meters high at the peak.
Each silo includes a Hutchinson Series
1012 Sweep Auger with a 100-tph capacity. The capacity of all the 254-mm
Hutchinson Grain Pump Loop Systems
is 150 tph. The facility also includes two
grain pre-cleaners and one grain dryer. It
will be used to clean, dry and store corn,
wheat, sorghum and soybeans. The facility is completely automated and is
controlled from a PC or remotely from
a tablet.
After starting operations of the facility equipped with the Hutchinson Grain
Pump Loop System, the Ascension
Cooperative emphasized its operative
ﬂexibility, simplicity of use and ease in
automation.
TIRYAKI OPENS ONE OF THE LARGEST
ASSEMBLED PLANTS IN EUROPE
Silos Córdoba, Cordoba, Spain, recently ﬁnished work on one of the biggest plants assembled in Europe. The
Tiryaki project in Mersin, Turkey, was
for the storage of lentil, wheat and rapeseed. This was Silos Cordoba’s ﬁrst
time working with Tiryaki. Assembly
took nearly a year, from October 2011
to November 2012.
The facility includes:
• 19 silos model 18.33/22 with a diameter of 18.33 meters, height to the eaves of
25.17 meters, total height of 30.46 meters
and a capacity of 7,110 tonnes.
• 11 silos model 14.51/22 with a diameter of 14.51 meters, height to the eaves of
25.17 meters, total height of 29.36 meters
and a capacity of 4,395 tonnes.
• Six silos model 21.39/22 with a
diameter of 21.39 meters, height to
the eaves of 25.17 meters, total height
of 31.34 meters and a capacity of
9,752 tonnes.
• Four hopper silos model 9.17/12
with a diameter of 9.17 meters, height
to the eaves of 19.22 meters, total
height of 21.87 meters and a capacity
of 1,063 tonnes.
• 27 silos model 4.65/6 for bulk expedition with a diameter of 4.65 meters,
