Definitions

  • the present invention pertains to a sample-holder able in particular to conduct measurement of the draw and humidity of porous objects such as cigarettes or similar.
  • Its subject is more particularly, but not exclusively, a sample-holder of said above type able to be integrated into a module for measuring the characteristics of cigarette batches, and designed so that it is able to carry out a sequence of measurements of weight, draw, filter ventilation, paper ventilation and compactness.
  • draw measurement causes a modification in tobacco humidity on account of the aspiration of an air stream through the cigarette. Consequently, the humidity of the tobacco sample in the weight measurement module and the humidity of the tobacco of this same sample in the compactness measurement module are different. If a single humidity module is used, only one of the two humidity values can be measured (before or after draw) since this characteristic is modified during measurement of draw. This therefore leads to errors.
  • the purpose of the invention is more particularly to overcome these drawbacks.
  • the device of the invention may comprise a tubular body comprising:
  • the distance between the iris diaphragm and the lower end of the sphincter being slightly shorter than the length of a cigarette.
  • said above body may comprise a second sphincter with which to encapsulate the filter opposite the first sphincter with respect to a filter ventilation zone so as to channel the flow of filter ventilation for its measurement.
  • the sample holder alone can carry out a sequence successively comprising measurements of:
  • the single FIGURE is an axial section of a sample-holder according to the invention.
  • the sample-holder 1 is intended to perform measurements on batches of cigarettes of which one cigarette, positioned on the sample holder, conventionally comprises a tobacco rod 2 contained in a cigarette paper wrapping 3 extended at one end by a ventilated filter 4 comprising, in its central part, an annular zone with ventilation holes 5 .
  • This sample-holder 1 comprises a cylindrical structure made of three tubular parts 6 , 7 , 8 joined to each other with gas-tight assembly, namely:
  • the cigarette is inserted into the sample-holder 1 .
  • the cigarette centred by the hopper 14 enters the passage delimited in particular by the cylindrical portion 18 , the cylindrical tube 25 and the two sphincters 28 , 31 which, with iris diaphragm 19 , are then in a retracted state caused by aspiration.
  • Telescopic abutment means then enable the cigarette to be held in the sample-holder 2 , a position in which the lower end of the filter 4 is substantially located at the lower end of the sphincter 31 , while the upper end of the tobacco rod 2 is located slightly above the iris diaphragm 19 .
  • Sphincters 28 , 31 and iris diaphragm 19 are then placed under atmospheric pressure and change to the deployed state so that:
  • the sample-holder 1 is then ready to perform its sequence of measurements, namely:
  • this microprocessor also controls:
  • One important advantage of this solution is that, with the integration of the humidity measuring cavity within the draw module, it is possible to measure humidity before draw, to correct weight, and after draw to correct compactness using a single humidity sensor.
