A granule delivery system contains a plunger and a divided tube, wherein the divided tube has two or more partial shells which are suitable to be coupled to each other, so that a longitudinal channel is formed in the divided tube, each of the partial shells is able to move longitudinally in relation to the other, and the plunger is able to be inserted into the longitudinal channel, when the two or more partial shells are coupled to each other.本發明關於一種顆粒輸送系統,其含有柱塞及剖分式管,其中該剖分式管有適於互相耦接的二或更多部分殼部,所以當該二或更多部分殼部互相耦接時,該剖分式管中便形成一縱通道,每一個該等部分殼部相對於另一個縱向移動,而且該柱塞能插入該縱通道。
