Title
(EN) AIR ACCELERATOR DOSING TUBE
(FR) TUBE DE DOSAGE D'ACCÉLÉRATEUR D'AIR
Abstract
(EN)
An air accelerator dosing tube for a form/fill/seal machine used to package fine cut tobacco material includes an axially-adjustable annular venturi communicating with the particulate material passage. A lining of polyether ether ketone optionally covers surfaces exposed to the particulate material. A metering assembly for delivering predetermined quantities of particulate material at predetermined time intervals may also be fabricated from polyether ether ketone. Each dosing tube is adapted for calibration by adjustment of the annular venturi to produce a predetermined force at a predetermined stand-off distance. In operation, consistent simultaneous operation of multiple dosing tubes, each of which has been calibrated, gives substantially uniform deposit of particulate material in pouch-type packages. The particulate material may include finely cut tobacco in addition to humectants, flavorants, and other tacky substances.
(FR)
L'invention concerne un tube de dosage d'accélérateur d'air pour une machine de formage/remplissage/fermeture utilisée pour emballer une matière de tabac finement découpée, le tube comprenant un venturi annulaire réglable dans la direction axiale qui communique avec le passage de la matière particulaire. Un revêtement de polyéther éther cétone recouvre éventuellement des surfaces qui sont exposées à la matière particulaire. Un ensemble de dosage destiné à débiter des quantités prédéterminées de matière particulaire à intervalles de temps prédéterminés peut aussi être fabriqué en polyéther éther cétone. Chaque tube de dosage est apte à être calibré par le réglage du venturi annulaire pour produire une force prédéterminée à une distance d'écartement prédéterminée. En fonctionnement, la manœuvre simultanée constante de multiples tubes de dosage dont chacun a été calibré donne un dépôt sensiblement uniforme de matière particulaire dans des emballages du type poche. La matière particulaire peut contenir du tabac finement coupé en supplément de substances humidifiantes, aromatiques et d'autres substances adhésives.
