The Wynveen micro-ingredient dosing system is available with up to 34 dosing cells, each with a dosing screw. Rotary discharge equipment can be provided as an option for products with poor flow characteristics.
The dosing screws discharge into one, two or three weighers, depending on the total number of ingredients. The weighers can be installed at different levels and work simultaneously. In the set-up with three weighers, the top weigher has a net weighing capacity of 5 kg, the middle weigher 10 kg and the bottom weigher 50 kg.
They are accurate to 5, 10 and 50 g respectively.
The storage bunkers for the ingredients are made from stainless steel or st 37 steel with a food-quality internal coating. The dosing screws are available in different diameters, with the larger ones having a fine dosing screw underneath for maximum accuracy.
In modern feed mills, micro-ingredient dosing often operates in-line with the central batch system. Depending on the size of the batch, it may be advisable to homogenise the dosed micro-ingredients first with a carrier in a separate mixer before adding them to the main batch.
