Definitions

  • the present invention relates to a mobile drier for cereals.
  • Conventional driers are provided with a fixed drying column and are constituted substantially by gravity driers and generally comprise: in the upper part, a storage hopper, which is required to preheat the wheat and is provided with level detectors in order to ensure automatic feeding of the drier; an actual drying region; an optional cooling region; a wheat extraction system; a hot air generator and a dust suppression system.
  • the driers with a fixed drying column usually entail advantages constituted by reduced breakage, arising from the type of descent and from the rotation of the grain between the caps; very low pulverization, arising from the type of conveyor system used, such as lifters or screw feeders rotating at a low rate; low energy consumption, arising from the thinner layer, thus using less energy to make the air pass through the mass and the dust, which are controlled by gates which close during product discharge.
  • the main drawback consists of the fact that because these are fixed systems they require the preliminary execution of adapted foundations and supporting bases at which the various individual components of the drier must then be installed.
  • Driers which can be carried on motor vehicles are also known as a partial solution to these drawbacks; the advantage of using a preassembled drier, which in any case requires adapted base supports, is combined with the considerable drawback arising from the fact that these driers are considerably bulky, requiring the use of special motor vehicles owing to their excessive width, which causes them to exceed standard clearance profiles; low efficiencies are also observed.
  • mobile driers which, in order to be transported within clearance profiles and therefore have a width which does not exceed three metres, are constructed by using very small lateral fixed humid-air chambers: in practice, this considerably reduces efficiency, since the air is forced to work at a very high speed, generating streams of air at different temperatures.
  • the aim of the present invention is therefore to solve the mentioned technical problems, eliminating the drawbacks of the prior art by providing a drier which can be transported on conventional motor vehicles and therefore within the clearance profiles and at the same time allows to achieve high quality levels, in that it allows to quickly and optimally remove humidity from the product even for large flow rates.
  • an important object of the invention is to provide a drier which is structurally simple and reliable in use and has low manufacturing costs.
  • a mobile drier for cereals characterized in that it is provided with shells which are adapted to be compacted for transport on motor vehicles within the normal clearance profile.
  • the reference numeral 1 designates a drier which is constituted by a supporting structure 2; adapted fans 3 for aspirating the moist air and channels 4 for feeding the wheat by virtue of adapted means, such as lifters or screw feeders with low rotation rates, are associated with said structure 2 in an upward region.
  • the drier is also internally provided with adapted drying regions, optionally with a cooling region, with means for extracting the wheat as a function of the relative humidity of the cereal, and with optional dust suppression systems.
  • the drier 1 is associable, by means of the supporting structure 2, with an adapted motor vehicle 5 so as to remain within its clearance profile.
  • the drier 1 can be loaded onto the chassis of an agricultural trailer 6, to which a tipping device 7 has been applied, or can be loaded onto the chassis of a road trailer or of a tip-truck with a low bed or directly on the chassis of a truck.
  • the particularity of the drier consists of the fact that it has, at its two opposite sides, adapted shells 8a, 8b which are movable and therefore adapted to be compacted for transport on said motor vehicle within its clearance profile.
  • Said shells 8a and 8b can be mutually associated by means of adapted vertical hinges 9a, 9b, 9c and 9d, which allow the accordion-like opening of the shells 8a and 8b with respect to fixed side walls 10a, 10b.
  • a drier is thus obtained which achieves the intended aim and objects, since it is complete and ready to perform drying once it has been transported on site; opening the hot-air and saturated-air shells allows to provide homogenization of the hot air at the input and a low flow-rate and homogenisation of the dried product at the output.
  • the environment is also protected, since the output dust is less than 10 mg/mc of air and the noise level is lower than 60 dB.
  • the cost of the drier is competitive with respect to a fixed drier, in comparison with which it offers approximately equal characteristics and advantages; the drier can be manufactured entirely in a workshop or factory and can be installed immediately on site for prompt and immediate use.
  • figures 18, 19 and 20 illustrate a drier 101 in which the shells 108a and 108b can be moved on planes which are approximately parallel to the fixed side walls 110a and 110b and are connected, at their ends, to pairs of panels 112a, 112b which are slidable externally with respect to additional fixed side walls 113a and 113b which are perpendicular to the fixed side walls 110a and 110b, which are approximately parallel to the shells 108a and 108b.
  • the shells and the pairs of panels accordingly provide a substantially C-shaped configuration which is slidingly associated externally with respect to the additional fixed side walls 113a and 113b.
  • Figures 21 and 22 illustrate another embodiment for a drier 201, in which the shells 208a and 208b are constituted by sheets which are resistant to high temperatures and which are associated, at their ends, at the fixed side walls 210a and 210b; said sheets are then inflated when the driver is operating.
  • the sheets that constitute the shells are deflated and therefore allow to transport said drier on a motor vehicle within the normal clearance profile.
  • Airtight means are of course provided at the regions connecting the hinges or pairs of panels or sheets.
  • the type of movement of the shells and their shape and arrangement may be the most pertinent according to the specific requirements.
  • the materials that constitute the individual components of the drier may also of course be the most pertinent according to the specific requirements.
