CompactingLACTOSPRAYER 100 ST /200 STWEDA UEDApplication: liquidDesign: 100/200 l tank withmounting, pump with filter,2-point siphoning (completedraining), flow meter.Ready for operation withall accessories.Output: 16 to 160 l/hDrive: 12 V DCArea of use: forage harvesters,forage wagons and large balersApplication: liquidDesign: electronically controlledcompact unit. Standard unit:2x5 l tanks for bacterialconcentrate. Dosing by ultra-finemisting. Ready for operationwith all accessories.Output: choice of 180 t/hor 270 t/hDrive: 12 V DCArea of use: forage harvestersIngress of oxygen leads to heating up and thus to energyand DM losses. Therefore, the better the silage is compacted,the less atmospheric oxygen can enter as silage is removed.The roller tractor weight determines the speed of theharvesting chain.Rule of thumb:Mountain performance, t FM/h= Roller tractor weight3*Targetvalues:* value for forage wagons;value for forage harvesters = 4DMDensity20 % 160 kg DM/m 37How to ensure optimum compaction:WRONGProjecting vehicle parts40 % 240 kg DM/m 3n Max. 20-30 cm layer thickness.n The higher the raw fibre and the dryprevent rolling rightup to the wall.matter, the thinner the layers.n Tyre pressure at least 2 bar.n Do not use twin tyres on side walls. 7WRONGn Max. rolling speed 3-4 km/hn Start rolling right at the beginning, asThe angle of the tractormakes it impossible toroll right up to the wall.otherwise the effect will not go downthrough the silage.n Avoid excessive rolling at the end, 3CORRECTbecause of the pump effect whenThe angle allowsthe silage springs back.rolling right upto the silo wall.14Note: well compacted silage minimises the risk of heating up.15
