| Box drying installations |  
| Efficient drying of seed in boxes with processors for automatically drying to the desired moist content level. | Evenness is the characteristic of optimal ventilation. This evenness is realized by means of the effective 1-layer air-distribution system. It works according to a logical principle. In this system the boxes are stacked in rows in front of the air-distribution system. The openings in the air-distribution system are aligned with the pallet openings at the bottom of the boxes. Air from the air-distribution system is blown through the boxes containing the product. |  | * Stacking 2-3-4-5 or 6 boxes. Using height gives maximum drying volume on minimum floor space; more drying capacity! * The openings in front of the air distribution system are on position of each box pallet. * Extraction outdoor air from the back by an opening in the wall. Recycling indoor air when outdoor is to moisty.  |  |  | | Pallet bottom closed by 9 mm plywood. | Difference in thickness between plywood and hardwood plank. | Difference makes openings between box layers for escaping moist air on each layer. |  |  |  | | Boxes are place in front and on top of each other. | A fan extracts outdoor or indoor air. Air will be heated or dried and distributed over the box levels. | Dry air extracts moist from the product and moist air escapes per layer out of the product. |  |  | | Axial fan | Centrifugal fan |  |  | | Protection grill (option) | Protection grating (option) | Heating Modulating propane gas burners  |  |  | | Warm air from burners

• With ‘Touch Screen’
• Complete automatically drying. Switch board (left)
• Example of switchboard with ADC processor for automatically drying.
• Controlling fan, heating, air valves/hatches and air dryer.
• Manufactured ‘custom made’.

• Controlling air capacity and heating.
• Comparing absolute moist ingoing and out coming air (gr/kg air). | Agra-Moist-Control (AMC) Processor. • Drying will stop automatically when ingoing air is to damp compared to out coming air.
• Drying will stop when seed is dry. |  |  |  | | HR and T° sensor for
measuring ingoing (dryer)
and out coming air (product). | Product sensor with
flexible cable. | Measuring out coming air
(product) by a box level. | Example of drying installations Mobile unit  |  |  | | Drying boxes in front of the
drying unit. Palets of boxes
goes with openings in dryer. | Mobile unit can be placed
in every place where you
need drying. | Unit complete with fan,
