Abstract

A method for temporary storage of granular material in a receiver having a horizontally elongated chamber within a housing, the chamber having a convex triangular cross-section and a dump flap defining a bottom vertex of the triangular cross-section, with a horizontal air/vacuum resin material inlet connecting to the chamber, and a horizontal air/vacuum outlet leading from and connected to the chamber.

First claim

I claim the following:

1. A method for temporary storage of granular material prior to processing thereof into a finished or semi-finished product, comprising,
a) feeding an air/vacuum stream carrying the granular material into a chamber in a substantially horizontal direction through a first substantially vertical side wall of the chamber, under vacuum;
b) reducing velocity of the stream in the chamber thereby causing granular material entrained in the stream to fall to the chamber bottom;
c) continuing drawing the stream from the chamber thereby maintaining vacuum in the chamber; and
d) releasing the vacuum from the chamber in a substantially horizontal direction, through a second substantially vertical side wall of the chamber opposite the first side wall, thereby allowing a bottom of the chamber to swing to an open position, in response to granular material resting thereon.

2. The method of claim 1 further comprising passing the stream through a filter after the granular material has fallen to the chamber bottom.
