  • Patent number: 4827628
    Abstract: Apparatus and techniques are described for using air to remove moisture from particulate material such as hay (e.g., alfalfa, clover, grass, etc.), other roughage feedstuffs, straw, and even finely ground feedstuffs. The apparatus includes a housing with an air inlet in the bottom portion and an air outlet in the top portion. The particulate material is conveyed out of the housing at the bottom. A fan draws air through the housing from the bottom portion to the top in a manner such that the air passes through and around the particulate material to absorb moisture. This also cools the particulate material.
