Definitions

  • the present invention relates to a smoking machine, and more particularly to a multi-port smoking machine, and to a method of smoking a plurality of smoking articles.
  • Multi-port smoking machines for collecting and analysing the constituents of tobacco smoke produced by a plurality of cigarettes or other smoking articles under controlled smoking conditions are well known in the art.
  • the mouth end of the cigarettes are placed in holders connected to smoking ports on the machine, and air is drawn through the lit cigarettes at regular intervals using one or more mechanically driven gas syringes or pumps.
  • Particulate and vapour phase constituents of the mainstream tobacco smoke drawn through the cigarettes are collected using one or more trapping systems, such as for example glass fibre (Cambridge) filters, impingers and gas collection bags, and then analysed to determine, for example, yields of tar, nicotine and carbon monoxide.
  • trapping systems such as for example glass fibre (Cambridge) filters, impingers and gas collection bags
  • each smoking port is coupled to a separate syringe or pump, which draws air through a cigarette placed in a holder connected to that smoking port.
  • mainstream smoke is drawn simultaneously through each cigarette and collected separately, i.e. the mainstream smoke is collected individually per smoking port.
  • the smoking ports are mounted on a head that is rotated relative to a single static syringe or pump, which draws air through cigarettes placed in holders connected to the smoking ports in turn.
  • the mainstream smoke drawn successively through each cigarette is collected cumulatively.
  • rotary smoking machines By allowing a cumulative mainstream smoke sample from a large number of smoking articles to be collected in a single run, rotary smoking machines advantageously generate a robust smoke matrix in a short period of time.
  • known rotary smoking machines are suitable for collecting smoke produced by conventional lit-end smoking articles, the rotation of the smoking ports during use can render them unsuitable for the collection of aerosols produced by alternative heated smoking articles.
  • an aerosol is produced by the transfer of heat from a combustible fuel element or heat source to a physically separate tobacco material, which may be located within, around or downstream of the fuel element.
  • tobacco material is heated by one or more electrical heating elements to produce an aerosol.
  • the electrical heating elements are externally powered, the associated power cables may disadvantageously become entangled or dislodged during use of known rotary smoking machines as a result of the rotary motion of the smoking ports thereof.
  • a rotary multi-port smoking machine comprising: a rotary valve; a plurality of static smoking article holders, each static smoking article holder being in communication with a corresponding static port disposed about the rotary valve; and a suction means.
  • the rotary valve is rotatable to selectively place each of the static ports in communication with the suction means so that, in use, air is drawn through a smoking article placed in the corresponding static smoking article holder towards the suction means to provide a puff.
  • a method of automatically smoking a plurality of smoking articles comprising: placing smoking articles in a plurality of static smoking article holders, wherein each static smoking article holder is in communication with a corresponding one of a plurality of static ports disposed about a rotary valve; and taking puffs sequentially through the smoking articles in the plurality of static smoking article holders by rotating the rotary valve to bring each of the plurality of static ports successively into communication with a suction means.
  • multi-port smoking machines according to the invention may advantageously be used to collect not only smoke produced by lit-end smoking articles, such as cigarettes, cigars, and cigarillos, but also aerosols produced by heated smoking articles (for example electrically heated cigarettes of the type disclosed in US-A-5,692,525 and heated cigarettes of the type disclosed in US-A-4,714,082 ).
  • a rotary valve also allows the dead volume between the plurality of smoking article holders of multi-port smoking machines according to the invention and the means for collecting smoke or other aerosols produced by smoking articles placed in the holders to be minimised.
  • the dead volume is reduced and minimised because multi-port smoking machines according to the invention have a smaller footprint due to the use of the rotary valve, which reduces the distance between the holders and the means for collecting the smoke or other aerosols. This advantageously reduces condensation and contamination of the smoke and other aerosols prior to collection as there is less surface area for the smoke and other aerosols to form on prior to reaching the collection means.
  • the multi-port smoking machine according to the invention comprises a plurality of static smoking article holders mounted on a static ring
  • contact between a rotary disc used to move the rotary valve thereof and the static ring can remove particles that have formed on the interior surfaces of the machine.
  • the rotary valve of multi-port smoking machines according to the invention is rotated in a stepwise manner against the suction means.
  • the plurality of static ports are brought successively into communication with the suction means so that, in use, puffs are taken sequentially through smoking articles mounted in the corresponding plurality of static smoking article holders.
  • Multi-port smoking machines may include any suitable known hydraulic, electrical, or electro-mechanical positioning means for indexing the rotary valve through a plurality of positions so as to bring the plurality of static ports successively into communication with the suction means.
  • the rotary valve may be indexed by means of an electric stepper motor or a pneumatic motor.
  • multi port-smoking machines may comprise any desired number of static ports and corresponding static smoking article holders.
  • multi-port smoking machines according to the invention comprise between 2 and 40 static ports. More preferably, multi-port smoking machines according to the invention comprise between 5 and 20 static ports.
  • Multi-port smoking machines may comprise any suitable suction means known in the art including, but not limited to, gas syringes and vacuum pumps.
  • multi-port smoking machines may include known computer control systems coupled to the suction means and the rotary valve positioning means.
  • multi-port smoking machines according to the invention comprise computer control systems comprising a programmable logic controller (PLC) and a human- machine interface (HMI).
  • PLC programmable logic controller
  • HMI human- machine interface
  • the computer control system may also be used to select the number of static ports of the multi-port smoking machine through which air is drawn in use. This advantageously allows puffs to be taken from smoking articles placed in all or only a pre-selected number of the plurality of static smoking article holders of multi-port smoking machines according to the invention.
  • Multi-port smoking machines preferably further comprise: at least one central trap located between the ports and the suction means for collecting one or both of particulate phase components and vapour phase components of smoke or other aerosols produced by smoking articles placed in the smoking article holders.
  • Multi-port smoking machines may comprise central traps for, in use, collecting (i) one or more particulate phase components or (ii) one or more vapour phase components or (iii) one or more particulate phase components and one or more vapour phase components of smoke and other aerosols produced by smoking articles placed in the holders thereof.
  • Known trapping means that may be used as central traps to collect particulate phase components in multi-port smoking machines according to the invention include, but are not limited to, filters, such as glass fibre (Cambridge) filter pads and electrostatic precipitators.
  • Known trapping means that may be used as central traps to collect particulate and vapour phase components in multi-port smoking machines according to the invention include, but are not limited to, impingers and cold traps.
  • At least one central trap in multi-port smoking machines according to the invention advantageously allows the collection of a cumulative smoke or aerosol sample from a plurality of lit-end or heated smoking articles in the smoking article holders i.e. the collection of a single sample from a plurality of ports.
  • the at least one central trap is releasably connected to the remainder of the multi-port smoking machine so as to allow easy removal and replacement thereof.
  • multi-port smoking machines may further comprise: a plurality of peripheral traps, each peripheral trap being located between one of the plurality of smoking article holders and the corresponding port for collecting particulate phase components of smoke or another aerosol produced by a smoking article placed in the smoking article holder.
  • peripheral traps in multi-port smoking machines according to the invention advantageously allows an individual smoke or other aerosol sample from each smoking article placed in the smoking article holders to be collected separately i.e. the collection of a single sample from a single port.
  • Known particulate phase trapping means that may be used as peripheral traps in multi-port smoking machines according to the invention include, but are not limited to, filters, such as glass fibre (Cambridge) filter pads.
  • the plurality of static smoking article holders and corresponding static ports are arranged around the rotary valve such that each of the static smoking article holders and corresponding static ports is equidistant from the rotary valve.
  • the plurality of static smoking article holders and corresponding static ports are disposed circumferentially about the rotary valve. More preferably, the plurality of static smoking article holders and corresponding static ports are equiangularly circumferentially spaced about the rotary valve.
  • Multi-port smoking machines may comprise different static smoking article holders depending upon the type of smoking articles from which puffs are to be taken.
  • multi-port smoking machines according to the invention for use in collecting components of smoke drawn through lit-end cigarettes may comprise a plurality of static conventional cigarette holders with labyrinth seals, latex holders or vent blocking holders.
