Uprated bin system for organic cereal grower

This organic grower produces a number of different cereal crops which necessitates the smaller amounts being stored separately.  An existing Norfolk barn with a precast concrete square bin system was uprated to dry and store all the client’s cereal crops.

The old Bentall dryer was removed with most of the existing handling equipment.  The new drying system consists of a 80tonne round open top Brice-Baker silo installed in place of the old dryer and has a drying floor and Harvest Installations Maxi-stirrer with 5hp fan and Harvest Installations Constant Humidity Controller.  This provides a batch dryer that keeps up with the smaller amounts of grain being harvested on this organic farm.  The large amounts of moist air given off in the high temperature fast drying stirrer system is extracted from above the silo, which also provides dust extraction when loading the silo.

store-2The store is loaded via the existing intake pit and conveyor into a new Perry chain and flight elevator that feeds via a Perry aspirator cleaner onto a new Perry top conveyor. This is used to feed the drying, silo storage bins and lorry loading out of the far end of the building at 45tph.

store-4The storage bins have been hoppered with timber hoppers to make the emptying easier.  They are emptied via the existing belt conveyor and elevator, whose output drops down through the existing Turner cleaner, if required, into a new Perry bottom conveyor which passes under the drying silo back to the new input elevator and onto the top conveyor.  The drying silo is emptied through a sump under the drying floor into the bottom conveyor, the rack and pinion slide being controlled from outside the silo.  A sweep auger is lowered from the catwalk to remove the remaining grain.
