Hartley Farms Ltd specialise in the cleaning, drying and storage of grain and in treating and improving rejected loads and off farm products. Their facility processes approximately 7,000 tonnes of contaminated grain and dries and cleans approximately 13,000 tonnes of grain per year.
Since 1999 Hartley Farms have purchased a large quantity of drying and handling equipment from Perry. The first large item was a 50 tph mobile reception hopper to intake grain into a rotary cleaning plant. This was
followed the same year by conveyors to feed a new 5000 ton storage building which is filled by a 50 tph travelling conveyor. This was
followed in 2000 by an M210 continuous flow 15 tph grain drier and
associated handling equipment . In 2003 a gravity table was installed with associated handling equipment.
In 2004 Perry’s Northern area sales manager—David Caley continued his close relationship with the Hartleys by doing the detailed drawings for the installation of an optical separator and associated handling equipment.
Perry supplied 7 elevators and conveyors comprising:
2 off belt & bucket elevators capacity 25 tph
1 off 35 tph levelling chain & flight conveyor
1 off 20 tph inclined chain & flight elevator
3 off 25 tph horizontal chain and flight conveyors
This machine uses optical recognition technology to separate impurities from crops. It can separate ergot ( a poisonous fungus) from cereals, thus turning an unsaleable crop into a valuable commodity. It will also
separate wheat from oats, wheat from barley, weeds from rape. It can also remove both pink, black grains and wild oats from samples.
During this season the separator has recorded throughputs of up to 12 tph on cereals dependant upon the amount of impurity being removed.
One separator operation has been recorded as removing in excess of 273,810 wheat seeds per minute from a sample of oats grown for porridge which was rejected for being impure. After one pass through the
separator the oats were accepted by the buyer with no deductions.
