Definitions

  • Cereal dryers are known in which the cereal grains are in direct contact with hot combustion gases originating from the combustion of solid or liquid fuels. These dryers have a good thermal efficiency but the condensable products contained in the combustion gases are partially deposited on the goods and alter their quality.
  • Cereal dryers are also known in which the cereal grains are dried by air heated by tube radiators in which steam circulates.
  • the cereals thus dried are of good quality, but indirect drying by steam has a poor thermal efficiency and therefore consumes a lot of fuel.
  • the present invention combines the advantages of the two known systems, by drying the cereals with air heated by a heat exchanger through which the combustion gases pass.
  • the grain dryer shown has a vertical metal enclosure 1 with open ends, rectangular in horizontal section. This enclosure is divided from top to bottom into a converging transpiration section 2, a middle section 3 and a diverging cooling section 4. On one side of the middle section is fixed a combustion chamber 5 in which the flame of a burner burns. oil 5A.
  • the combustion gases exit from the chamber 5 via two conduits 6 and 7.
  • the gases leaving the conduit 6 reach a heat exchanger 8 placed laterally outside the enclosure, on the upper half of the middle section.
  • This heat exchanger is in the form of a radiator comprising a distributor duct 9, a vertical row of horizontal tubes 9 A with external fins and a manifold duct 10.
  • the combustion gases are finally evacuated through a suction blower 11 to a smoke duct not shown.
  • the combustion gases leaving the combustion chamber 5 via the pipe 7 circulate in a coil 12 lining the internal surface of the transpiration section 2 and are evacuated through a suction blower 13 also towards a smoke duct not shown.
  • a gas temperature adjustment chamber respectively 14 and 15, provided with a dilution air inlet orifice controlled by a register, respectively 16 and 16 A.
  • the rear wall of the middle section 3 is pierced with two circular orifices 17 and 18 in which are mounted two suction fans not shown.
  • the orifice 17 is located at the level of the radiator 8.
  • the front wall of the median section 3 is pierced by two rectangular openings 17 A and 18 A, one at the level of the radiator and of the same size as the latter, the other at the lower orifice 18.
  • baffles 19 of cylindrical shape convex upward, extending from the anterior wall to the rear wall of the enclosure. These baffles are arranged in several horizontal rows in staggered rows, spaces being provided between the rows and between the baffles of the same row.
  • the cereal grains brought above the upper orifice of the enclosure 1 by any suitable means, such as a ribbon conveyor, fall into the upper section 2, or of perspiration, and pass through it. In this section, the grains are heated by radiation by the coil 12 and lose their surface moisture.
  • the grains then fall into the middle section 3 of the enclosure, where they meet a horizontal current of air heated by the radiator 8, which current enters through the opening 17 A situated opposite the radiator in the anterior wall, and leaves through the suction fan placed in the orifice 17, the grains thus dried continue their fall in the middle section 3 and meet a cold horizontal air flow which enters the enclosure through the opening 18 A of the anterior wall , located at the orifice 18, and which exits through the suction fan mounted in this orifice 18,
  • the grains are temporarily retained by the baffles 19 for their partial cooling, after which they finish their cooling in the lower section 4 where they move against the current in an ascending cold air stream, also drawn in by the fan mounted in the orifice 18.
  • the grains, leaving through the lower orifice of the enclosure 1 are collected and routed to a storage location by any suitable means, such as a ribbon conveyor, not shown.
