Micro-ingredient dosing systems

The Ottevanger micro-ingredient dosing systems can be designed to include up to 34 dosing cells, each equipped with a screw feeder. Rotary discharge equipment can be provided for poorly flowing products as an option.

The screw feeders discharge into one, two or three weighers, depending on the total number of components. These weighers can be setup on various levels and work simultaneously. When utilizing three weighers the maximum capacity of the top weigher is 10 pounds, the middle one 20 pounds, and the bottom one 100 pounds. They are all accurate to 0.1%.

The micro-ingredient dosing systems have two flexible rotary valves with a flexible connection which acts as an airlock. The separate bins are made of stainless -or mild steel and have a special inner layer for food products. The dosing screws can have different diameters. A larger screw is provided with a smaller screw underneath to achieve optimum accuracy.

In modern feed plants can the micro-ingredient dosing system work inline with the central charge system.

The storage bunkers for the components are made from stainless steel or steel ST37 with a food-quality internal coating. The screw feeders may vary in diameter, with the larger ones having a fine-dosing feeder underneath for maximum accuracy.

In modern animal-feed installations the micro-ingredient dosing often operates in-line with the central batch system. Depending on the size of the batch it may be a good idea to homogenize the dosed micro-ingredients first with a carrier on a separate mixer before adding them to the main batch.
