KRONE OptiMaize

- KRONE chopping technology for optimum maize forage quality
- OptiMaize S, M, L, XL for variable chopping lengths from 4 mm to 30 mm
- KRONE MaxFlow and Biogas drum with different blade specifications combine to produce chops of the required length
- KRONE corn conditioner for optimum fracturing and kernel treatment
- KRONE VariLOC for flexible long and short chops without conversing the machine

OptiMaize S: Maize that is harvested to fuel biogas plants is chopped to very short lengths. Depending on moisture levels, chops of 4mm to 7mm lengths have been found ideal for this application, because shorter chops make the energy readily available to the methane producing bacteria in the fermenter thereby increasing gas yields. The KRONE forage harvesters use a Biogas drum with 40 or 48 blades to harvest biogas maize. Alternatively, OptiMaize S results can also be achieved with the 36 blade MaxFlow drum. For good fermentation, the leaves and stalks are subsequently fractured and the kernels destroyed by a KRONE corn conditioner with 123/144 teeth and rotors rotating at a 30 % speed difference.

OptiMaize M: Grass based rations for beef bulls and dairy cows which consist of up to 40 % of maize should be made up of 8 mm to 10 mm (0.3" to 0.4") chop lengths. This length of cut and an appropriate conditioning intensity avoids lack of fibre in the ration. OptiMaize M chopping quality is achieved by the MaxFlow drums with 36 and 28 blades. The ideal conditioner is the KRONE corn conditioner with 123/144 teeth whose speed differential can be increased from 30 % to 40 % or 50 %.

OptiMaize L: Chop lengths of 11 mm to 19 mm (0.4" to 0.7") are ideal for dairy feed rations where the percentage of maize is about 60 %. Rumens require silage maize that is reach in fibres. The OptiMaize L chopping quality is achieved by the KRONE MaxFlow drums with 28 or 20 blades. The complementary conditioner for these drums is the assembly with 105/123 teeth.The speed differential on these rollers can be increased from 30 % to 40 % or 50 %.

OptiMaize XL The maize in dairy feed rations made up of more than 80 % by maize and that do not contain sufficient quantities of grass and feed straw should be chopped to 20 mm to 30 mm lengths to avoid lack of structure in the feed. The ideal drum for long chops is the MaxFlow drum with 20 blades which is complemented by the KRONE corn conditioner with 105/123 teeth and 30 %, 40 % or 50 % speed differentials. The KRONE disc conditioners offer a 2.5 times larger friction surface area and therefore are the best option for optimum conditioning at maximum outputs.
