GrainPro Ultra Hermetic Bunker™

GrainPro Ultra Hermetic Bunker™ can be made very simply by spreading out low density PE sheets on the bottom of a U- shaped compound consisting of an earthen ramp. A better solution is to cover the ground with asphalt or concrete and to replace the earthen ramp with a concrete or metal support wall. The large pile of grain is made by a grain thrower or grain pump, to be finally covered by large PVC sheets which come partly assembled to the site. The sheets will be welded together on top of the pile with a manual heat welder. Ends of PVC sheet and LDPE sheet are rolled together and buried in a surrounding trench to obtain ultra hermetic sealing. The ramp is covered with plastic sheeting to prevent being flushed away by rain draining from the bunker “roof”. When disassembling, PVC sheets will be cut neatly and stored on pallets for reuse in next season. The application of this technology is subject to certain climates and low MC’s of grain due to risk of condensation.

GrainPro Ultra Hermetic Bunker™ are sealed by folding top and bottom PVC sheets together at the edges and weighting the fold with earth or sand bags. They are designed to hold large quantities of grain to be stored for several months or years.

GRAINPRO ULTRA HERMETIC BUNKER™ IS THE OPTIMAL SOLUTION WHEN:

• Silos are filled to capacity

• Regional depots cannot hold post-harvest grains

• Transport systems are bottle-necked

• Storage of grain is economically feasible in anticipation of better prices

• National grain reserves requiring long storage periods are needed

 

OVERVIEW:

• 5-year PVC life span

• PVC membrane is impermeable to water, water vapor and air

• Food grade PVC

 

BENEFITS:

• Multi-year, multi-use life span

• Investment in infrastructure is minimal and only a small fraction of traditional storage methods

• Virtually no operating expenses

• Eliminates the need for expensive, hard to handle, noxious chemical insecticides

 

GRAINPRO ULTRA HERMETIC BUNKER™ DIMENSIONS ARE DETERMINED BY:

• The height your grain loading equipment can reach

• The amount of grain to be stored and the angle of repose

• The height of the retaining walls (i.e. earthen beams, pre-fabricated concrete panels or corrugated steel sheets)
