Abstract: A chip bin construction, ideally suited for bins having a maximum diameter of twelve feet or more, uniformly discharges chips, after steaming, without the necessity of a vibratory discharge. A hollow transition portion is provided between a main body which is a right circular cylinder of a first diameter, and a nonvibrating discharge which has a second diameter typically 1/3 or less that of the first diameter. The hollow transition includes a first, uppermost, portion having a generally right rectangular parallelepiped configuration including opposite side faces having generally triangular shapes, and providing one dimensional convergence and side relief; a second portion tapering from a generally rectangular parallelpiped configuration at an upper part to a generally circular configuration at a lower part and having opposite side faces having generally triangular shapes which align with said first portion generally triangular shapes to define substantially diamond shaped wall portions.
