## Abstract

A device for removing particulates from plant matter that includes a shelf through which the product is introduced into the device where the plant matter is moved through toward an output wherein the machine includes a lower conveyor belt, an upper conveyor belt, drive assemblies for both conveyor belts with adjustable speed wherein each conveyor belt is supported by a shelf and wherein the upper portion of each conveyor belt is moving in the direction opposing the other one resulting in the conveyor belt portions in contact with the product traveling in the same direction. An air source is provided that forces air through product as it travels between both conveyor belts through a fixed lower conduit and an upper conduit that is movable in an upward direction through a pivoting mount across the top conveyor belt that allows for displacement of the conduit from the lower conveyor belt as the product moves through the device.

## Claims

### Claim 1

A device for feeding plant matter for removing particulate matter therefrom comprising:
a lower porous conveyor belt with an air source that can direct air flow past the bottom of plant matter being fed over the top of said lower porous conveyor belt;
an upper porous conveyor belt with an air source that can direct air flow past the top of said plant matter being fed beneath a bottom horizontal portion of said upper porous conveyor belt
wherein said air source is supporting by a pivoting mount assembly that allows the end of said pivoting mount closest to said plant matter to maintain a constant distance from said plant matter.

### Claim 2 (depends on 1)

The device as defined in claim 1 wherein said lower and upper porous conveyor belts are sprocket driven connected by a 1 to 1 ratio chain drive that causes both of said conveyor belts to travel at the same linear speed.
