① Structural reinforcement
....- Apply “Stiffener,” specially designed for wall reinforcement
② Higher safety rate to static load and stress
....- Prepared for disasters including earthquakes

① Electronic domain device applied - Patent registered
....- Specially designed electronic right & left reverse turning device (Reverse turning angle is
adjustable): Fully complement the problems of existing mechanical devices.
....- Minimum failures & semi-permanent use: Excellent agitation
....- Mercury switch to each vertical auger: Prevent vertical augers from breaking away from paths
② Agitator check table installed : Install a worktable where non-professionals can inspect
and repair it (less cost for A/S)
....- Prepared for disasters including earthquake
③ Separate control panel installed for agitator only
....- Vertical auger starts sequentially one by one
....- When one vertical auger stops, other augers
stop at the same time
....- Diagnosis of vertical auger failures Failure handling, machine protection, and less load to silo
④ Strong gear motor : durability, quakeproof, sufficient driving force 

① Ventilation & drying of unstirred grain around the wall
....- Compensation of non-uniform ventilation due to unstirred grain around the wall: Blow air to
grain around the wall and prevent grain deterioration against non-uniform drying
② No dew condensation of inner wall
....- Prevent grain deterioration and spoiling against dew condensation by applying ventilation
between wall and inner double walls
③ Insulation effect
....- Prevent a temperature change of stored grain against outside air by forming air space
between silo wall and liner. Minimize heat loss during drying
④ Structural reinforcement of silo
....- Prevent silo deformation against outside force by using a galvanized steel plate
⑤ Easy installation & disassembly
....- Easy to install and disassemble as it is assembled to wall bolts of the silo
⑥ Less cost for insulation
....- Reduce an installation cost by 30% compared to that of urethane insulation.
Reduce an installation cost in combination with silo assembling bolts 
① Install a safety check table for divider and agitator
② Use a manhole installed at loop cap as entrance ⇒ Easy access
③ Easy inspections and repair works ⇒ Safe work space for A/S, easy work, and less time
④ Easy to adjust an angle of dispersion for evenness degree
① Install a safety check table for divider and agitator
② Use a manhole installed at loop cap as entrance ⇒ Easy access
③ Easy inspections and repair works ⇒ Safe work space for A/S, easy work, and less time
④ Easy to adjust an angle of dispersion for evenness degree
① Height of porous plate installed: 1 M (Highest in Korea)
② Easy to enter the bottom door of silo and secure a large work space for
inspecting and repairing bottom machines- Solve existing problems
③ a porous plate to be horizontal even on an unsmooth base by using a
height-adjusting mode
④ Excellent structural durability by using a square steel pipe for structural
purpose (2B)
① Device to discharge remaining grain after natural discharge
② Special sealed design: Prevent grain from being caught in the device
③ Discharge at low speed by adopting a deceleration wheel ? Minimize damages
to grain and solve problems of rubber wheels
