K. M. Duncan Agricultural Engineers Ltd recently secured a contract to upgrade Mr Mitchell’s of Allan Hill Farm, Fife, handling and drying equipment. The farm had an old Law Denis drier which had finally worn out after 24 seasons and could no longer keep up with the required capacity, the previous set up had become dated as modern machines could not easily fit into the buildings to work. When the farm decided to upgrade they chose to install a Perry of Oakley Ltd M310 Drier with matching 60tph handling equipment.
The farms main focus for drying is wheat, barley & oilseed rape, they will be aiming to put around 2000 tonnes of product through the new drier each year. They are also large producers of Scottish Strawberries.
The new installation has a large intake pit to allow for fast trailer turn around, but everything else has been installed above ground. From the intake pit the grain passes through a Perry 60tph aspirator cleaner to remove as much dust and chaff as possible before being transported to the drier via a 60tph double lift belt and bucket elevator.
The new 22tph Perry Drier has been assembled outside and a new building has been built around the drier to align the pit and allow for a more efficient flow of product through the system. The drier is tall and narrow to keep the footprint as small as possible. The fans have been mounted vertically to keep the footprint of the drier small and to help with noise reduction as Mr Mitchell has houses either side of the farm & the site office is located right next to the drier.
Before the grain is deposited in the stores it passes through a weigher, this allows Mr Mitchell to know exactly how much of each product he has available at any given time. Once the crop has been weighed a series of 60tph Perry inclined, curved and horizontal store conveyors transport the grain to the stores. Mr Mitchell has a total storage capacity of around 2000 tonnes.
Overall Mr Mitchell has had 1 drier, 1 aspirator cleaner, 1 double lift belt and bucket elevator, 8 conveyors and a range of ducting & valves installed. The whole system is controlled using the Perry’s PLC drier and plant control panel. This touchscreen PLC panel has been designed and programmed by Perry engineers and is capable of controlling up to 10 machines as standard along with the drier. The panel displays a mimic of the complete store as well as having multiple automatic routes available, making it simple to understand and use.
