The present invention relates to a particle automatic distributing apparatus and methods that work, the dispensing apparatus has one or more of the particle distribution module for distributing particulate material, such as a fragrance. According to the present invention, through a modular assembly with more than one distribution module for distributing a particulate material such as air fresheners provide automated dispensing apparatus and its operation method for distributing particles. Particle container of the dispensing module is g's one particle material, and is also formed holes for accurately and securely distributes the packed particle material by a predetermined amount. In the apparatus of the present invention it is a multiple particle distribution module can be selectively distributed in a predetermined amount by the particulate material from a plurality of particle materials with these distribution module with the help of compressed air. Automatic dispensing apparatus of the present invention can be distributed in PCT / IN2008 / 00871 there is a combined beverage dispenser introduced, provide the particulate material from a plurality of particle materials are supplied to a number of modules distributed by exactly a predetermined amount cup. Particle distribution, so distributing the different particle materials each module, there is no fear of contamination or particle materials are mixed.
