Definitions

  • the present invention relates to an apparatus for measuring the moisture content in solid bodies and particularly in cereals in general.
  • the apparatus of the present invention differs from those already known, wherein the separation of moisture from the solid, is effected by means of heat, and the weight-loss thereafter measured, in that the features of heat source, transmissio means, the sample tank, and the measuring apparatus are contained in a single unit so as to ensure good operational conditions being maintained at all times.
  • the features of heat source, transmissio means, the sample tank, and the measuring apparatus are contained in a single unit so as to ensure good operational conditions being maintained at all times.
  • the scale according to the present invention is characterised by a vertically displaceable drying-chamber into which penetrates one end of a rod to sustain the plate for the dried material, when the drying chamber is lowered, the other end of said rod projecting downwardly to support the moist material, an indicator being yoked to the rod intermediate of its ends.
  • the apparatus consists of a supporting tripod I, provided with adjusting screws for the true levelling of a central body 2 containing the measuring device, and a thermostatic drier 3 consisting of an insulated metal box provided with heating elements not shown for the sake of clarity.
  • the oven or drier 3 rests upon cylindrical supporting columns ID, ID, which are slidably disposed within suitable sleeves H, H. From a lateral wall of oven 3 projects a rotata'bly mounted shaft or rod l2, near the outer extremity of which is affixed eccentric l3.
  • a driving cord [4 is partly coiled about the peripher of eccentric I3 and passes through a well l5 to any convenient point of control.
  • oven 3 is shown in raised position, but normally the nethermost surface of eccentric I3 will rest against the upper extremity of well l5 and oven 3 Will assume the lowest possible corresponding position, under the influence of gravitational attraction.
  • cord i4 When cord i4 is forcibly retracted, rotation of eccentric l3 will thereby be brought about.
  • This will elevate rod I2, thereby causing oven 3 to be raised against gravity, whilst columns Ill, Ill correspondingly emerge upwardly through sleeves H, H.
  • the lid of drier carries a vent 6 for the outlet of the steam generated from the sample during its drying-up.
  • the moisture percentage may be read from a suitably graduated dial it.
  • a second plate, or sample pan, 8 upon which a moist sample may be placed, and the weight thereof determined at an instant when the oven is in a lowered position, in which position the upper pan 8 has ceased to be dependent or acting upon any portion of the weighing system proper, as hereinafter described in detail.
  • the rod 5 has a knife-edge engagement with the yoke 1 of the indicating device, and it will be apparent that the said rod will support both, the lower plate 8 and the plate 8' located in the drier 3, when said drying chamber is lowered to cause the plate 8' to be lifted from its supports 9 by means of the trident end 4.
  • Moisture determination apparatus of the type wherein a Weighed sample is dried in an oven and recharacterized in that a single balance is provided for the performance of both weighings, said apparatus including an upper oven section, a medial balance-containing section and a nethermost section containing a weighing an ior moist materials, means for predeterminedly altering the distance between said upper and said medial section, a substantially vertical connectng rod provided at the upper extremity thereof vith pan-engaging and loosingmeans and at the nether extremity thereof with said Weighing pan for moist materials, permanently affixed to said rod, engaging means at a medial portion of aid rod, permanently connecting it to said 0 since, a pan for dried materials, situated within said upper oven section so as to be engageable by said pan-engaging means When said upper and medial sections are moved to- Wards one another, and means permanently within said upper section for supporting said dried materia1 pan when said upper and medial sections are moved away from each other, whereby said last separation of sections permits said balance
