Definitions

  • This industrial design patent relates to a silo for drying hazel-nuts, almonds and other seeds artificially.
  • the silo according to the invention operates without submitting the product to rubbing or bumping as often occurs in current silos in which the seed is forced to fall from the bottom of a hopper into an underlying sheet plate pipe at regular preset intervals, where a current of forced air draws and lifts the product to the outlet of the pipe positioned above the silo.
  • the purpose of this invention is to design an artificial drying system, especially suitable for hazel-nuts, almonds and other similar seeds, which runs noiselessly and which does not damage the product.
  • the dryer according to the invention includes a large cylindrical tank with a vertical axis, consisting of a sheet plate conical hopper bottom, an external hollow space, an intermediate sheet plate buffer stage and a top fine mesh wire net buffer stage.
  • the internal part of the hopper has a series of closely drilled holes through which the pressurized incoming air flows by means of a supply pipe, inside the hollow space, used for diffusion, which encloses this internal wall.
  • a mixing unit is fitted above this tank; the mixing unit consists of one or more radial carriers which revolve slowly around the longitudinal axis of the tank; a lifting screw unit having a vertical axis and of different lengths, is suspended from each tank; these screw units generate a convective movement within the mass of seed which is gradually and slowly drawn from the bottom of the hopper to the top until it reaches the surface, from where it tends to fall down spontaneously into the spaces left empty by the upgoing seeds.
  • the silo in question consists of a cylindrical tank having a vertical axis (1), formed by a hopper (1a), an intermediate stage (1b) and a tap stage (1c); the stages (1b and 1c) both consist of a supporting cage frame formed by upright rods welded between two rings, one at the top and one at the bottom, each fitted with an external flange where the fixing bolts between the overlying stages are fitted.
  • the intermediate stage (1b) is buffered with a sheet plate while the top stage (1c) is buffered with a fine mesh wire net, through which the hot air introduced under pressure into the hopper (1a), can pass.
  • the hopper (1a) has an external hollow space (1d) for the diffusion of the hot air from the supply pipe (1e); the hot air enters the hollow space (1d) and then into the silo (1) through the holes specially drilled for this purpose on the internal wall of the hopper (1a).
  • the hot air entering the base of the silo can flow out only through the wire net of top stage (1c) or through the upper surface of the product stored in the silo and therefore it inevitably passes through the entire mass of the product.
  • a star wheel frame (2) is fitted above the top stage (1c) in order to support the mixing unit which consists of one or more radial carriers (3) which revolve around the longitudinal axis of the silo.
  • each carrier (3) consists of a box shaped supporting frame (3a) fitted externally with two wheels (3b and 3c), the first of which is a driving wheel, which rest and roll on the circular edge of the top stage (1c), while this frame is suspended at its internal end section to the shaft (4), having a vertical axis, by means of an axial bearing; this shaft (4) is rotated by the geared motor (5) fitted at the centre and above the frame (2).
  • a gear (9) is keyed on the outermost pin (6); this gear (6) rotates a second gear (11) by means of a drive belt (10) and the second gear (11), by means of a gear unit, in turn rotates the above drive wheel (3b), which rests and rolls together with the other idle running wheel (3c) along the top flange of the stage (1c).
  • shafts are fitted for the same number of screws (12) with a vertical axis and progressive height from the edge to the centre of the silo (1).
  • the noiseless running and the delicate handling of the product are due to the very low revolving speed of both the carriers (3) and the screws (12), while the rapidity of the drying process is due to the use of preheated pressurized air, which is diffused within the mass of the product stored in the silo, and to the efficient and continuous mixing of the product.
  • the seed can be emptied by pouring the same from the silo (1) simply by pulling the gate (13) which closes the outlet at the bottom of the hopper (1a).
