These systems are extremely suitable for utilizing residual heat from (green) power plants.This type of heat, as wellas exhaust air heat frompoultry houses can be used for drying poultry manure and turning it into avaluable organic fertiliser or fuel. Smoothly coated perforated steel plates are the basis of the Dorset Dryer. Its sturdy construction allows a thick layer (15 – 18 cm) of manure on the plates which guarantees a highly efficient drying process. It also allows a more compact design of the Dryer. When farm air is used for drying, the size of the dryer de-pends on the number of hens in the house. The number of hens per m2 drying surface is climate dependent: 400 – 600 hens per m2. Only a small part of the farm airpasses through the dryer (0,8 or 2 m3/h/hen). The rest of the air (summer ventilation) leaves the house directly. For example a dryer for 80.000 - 120.000 hens is 27 meters long,2 meters wide and 3 meters high. The industrial quality of the dryer guarantees interference free use of the equipment. The system works fully automatic and unmonitored.Low on service and user friendly, sizes from 10.000 up to 600.000 hens per dryer.In dried and pelleted form, poultry manure is a very good and popular fertiliser. Pre-drying in the farmhouse is no longer commonpractice. Skippingpre-drying gives abig electricity costreduction. Farm air of 20 degrees or more is normally sufficient to dry the produced daily quantity of manure. High temperature and low moisture gives the best drying results. The place of the drying system can be at the back or along the long side of the house.A dosing belt delivers the manure carefully on the smooth perfoplates. Therefore the manure canbe brought on the dryer in wetcondition, without pre-drying. The manure will only be transported by belts. No pre-drying, results in lower electricity costs. Dorset Pollo Poultry Manure Dryerreduces particulate matter emmisions from the barn air.Drying with theexhaust air fromthe farmhouseThe manure is removed from the farmhouse on daily basis, then dried on the dryer for two days. This limits the conversion to ammonia and op-timises the nitrogen content in the end product. The result is lessammonia in the air and a higher value end product.The dryer has 1 – 6 layers of perfoplates, drawn by a rolling chain. The drying starts at the top-layer, the manure drops down to the bottom-layer and is removed by an auger/screw system.The Dorset drying system isacknowledges by the Dutch govern-ment as a system that reduces ammo-nia emissions of poultry houses. Also dust and especially fine-dust is filtered from the farm air by the manure layer. The (fine) dust reduction is 70% of the total stable: 55%. (E.6.4.2)• Farm house air is blown through the manure, 0,8 – 2 m3/h/hen • The manure is daily removed from the house by belts and is normally dry within two days • Therefore no pre drying is necessary and ammonia emission in and outside the farmhouse is minimised, a reduction of more than 80 grams of ammonia per hen per year • The dust from the farm exhaust air is filtered by the manure layer. The reduction of (fine) dust is more than 70 %Dorset Aircleaning systemfor the poultryfarmWet dustfilterWet dustfilter + biological aircleaning + Pollo Manure Dryer, 60.000 layersand therefore suitable for export.Pelletising turns poultry-manure into a suitable product for long distance transport. Dorset supplies weighing and packaging systems for weighing and packing big bags as well as complete installations for weighing and filling small buckets and bags.The pelleting plant can be used di-rectly after the Dorset dryingsystem to process the dried product into pel-lets. In this way a high quality final product is created and new marke-ting possibilities occur. The dried manure is pelletised and then kept at 70°C for one hour for sanitization. The pellets are then free of germs A complete overview of the manure drying process at a poultry farmThe Dorset pelleting plantThe Dorset drying processanimationSee www.dorset.nuDorset Green Machines B.V.Weverij 26 • 7122 MS Aalten • The NetherlandsTel. +31 (0) 543 47 21 03 • Fax +31 (0) 543 47 53 55email gm@dorset.nuWWW.DORSET.NURFID-Technology,electronic identificationAir cleaning, andsorting systemsDrying installationsto make use of residual heat
