This invention is an apparatus and method for automatically adjusting the moisture content of feed grains to a relatively constant target level. As the grain is transported into, or within the feed manufacturing process, a sample is diverted through a continuous flow moisture sensor. The sensor generates an electronic signal proportional to the moisture content of the grain. This signal is used to control the application rate of a surfactant - water mixture, or of water alone. The water may be either in the form of steam or, as a hot or cold liquid. The grain then enters a mixing or contact chamber, into which the water is metered at a rate that is proportional to the moisture content of the incoming grain. The treated grain will have a relatively constant moisture content, eliminating one of the largest variables in the manufacturing of livestock feeds. |
