Patent CA-2278294-A1 (CA)
Inventor: IVERSEN JAN MEINCKE
IPC: A23K40/30
Filed: 1998-01-19
Abstract: In practice it is desirable to enrich feedstuff pellets with various additives in quite small amounts, e.g. only 100 g per ton, preferably that they are sprayed in a dissolved or suspended state on a flat stream of the pellets in cold condition. It is known to arrange this by using a falling stream of the pellets along an inclined chute. However, it is difficult hereby to achieve any particulary good dosing precision of the sprayed materials, some of which can be quite expensive. Moreover, the associated plants are difficult to install in normal premises. With the invention, a flat stream is produced by using an ejector wheel, whereby the chute can be quite short for reducing the construction height and, at the same time that this in itself improves the dosing accuracy, use is made of a continuous mass flow measurement which is used for the regulation of the dosing or the ejector capacity in achieving extra good liquid-dosing precision.
