Title: Improvements in grain or seed drying machines
IPC: F26B17/14
Filed: 1947-02-21
Abstract: 623,115. Drying grain. JONES, T. M. Feb. 21, 1947, No. 5160. [Class 34(ii)] In a grain drier of the kind in which the grain falls by gravity in a casing or tower and is subjected to hot air currents the casing comprises two similar series of inclined louvred platforms a - d down which the grain cascades, the top platforms a extending outwardly from a mid-position in the casing e to near the walls of the casing constituting in effect feed hoppers the grain then travelling Inwards and outwards down platforms b, c, d to the outlet f. Heaters h are provided as shown and air at atmospheric temperature is forced in 'by fans through ports j. The platforms are pivoted at their upper extremities and their lower ends, in some or all of the platforms, are adjustable towards and away from the wall of the casing. In action, cool atmospheric air blown in by the fans through ports j pass through the platform d and the grain descending them so that it cools the grain and extracts moisture. The air then passes over the heaters h and through the platforms c, b and after passing over the heaters h through platforms a where it meets the cool grain entering the dryer. This entering grain cools the air to approximately atmospheric temperature and with a possible deposit of moisture from the air on the grain which avoids toughening the outer portion of the grain and enables the internal moisture of the grain to be more evenly distributed in the grain as it becomes heated by the air passing through the lowered platforms so that the grain is more readily dried. As shown, platforms c are connected by cables o to a winding drum whereby they may be adjusted and collars may also be provided on the cables o for engagement with abutments on the platforms b whereby these platforms may also be adjusted.
