1.3.1. Functional Overview
The GrainVac is a simple and reliable system. It uses a vacuum to produce a flow of air
that conveys grain or material to the body of the machine. The flow of grain is directed
into an auger that conveys it to the transport vehicle. The heart of the system is the
rotor(s) (also known as blower(s) or fan(s)). The rotor(s) (A) remove air from the body
and places the entire system under vacuum. This vacuum causes air and grain to enter
through the intake (D) and flow through the hose (C), into the body (E) of the machine.
When the stream of air and grain reaches the body (E) of the GrainVac, it is separated
by the drum (B).
The stream of material is directed into the auger flighting, moved up the auger tube (F)
and discharged out the end dump double doors (G). The stream of air is cleaned of large
particles by the rotating drum and the air continues on through the drum into the rotor(s)
(A). The rotor(s) force the air out of the body into the exhaust (I) and out the air outlet
(H).
