US 8,757,388 B2 · Biomass conditioning system and method for conditioning

Abstract

The disclosure is directed generally a biomass conditioning system and methods for conditioning biomass to remove undesirable material for further processing and applications. In some embodiments, the disclosure includes a biomass conditioning system including a conditioning tank, a water input device, a biomass input device, a containment device, a spillway, and a moving separation device. In some embodiments, methods according to the disclosure include pumping water into a conditioning tank, depositing biomass into the conditioning tank, allowing the biomass to soak in the water and separate into a bark portion and a non-bark portion, allowing the bark portion to float to a water line, containing the bark portion to one side of the conditioning tank, moving the bark portion into a bark storage area, separating the non-bark portion into a biomass portion and a debris portion, and moving the conditioned biomass portion into a storage area.

Dependent claims

A biomass conditioning system comprising:

a conditioning tank having a bottom portion and a wall portion;
a water input device configured to fill the conditioning tank with water to a water line;
a biomass input device configured to deposit biomass into the conditioning tank and immerse the biomass in the water, thereby causing the biomass to separate into a floating portion and a nonfloating portion, the nonfloating portion comprising nonfloating biomass and debris;
a containment device configured to:
divide the conditioning tank into a first side and a second side;
and
contain the floating portion of the biomass in the first side of the conditioning tank;
a spillway located on the first side of the conditioning tank, the spillway being configured to transfer the floating portion of the biomass to a first storage area;
and
a moving separation device at least partially submerged in the water, the moving separation device being configured to permit passage of the debris and to transport the nonfloating biomass out of the second side of the conditioning tank and into a second storage area.

A biomass conditioning system comprising:

a conditioning tank having a bottom portion and a wall portion;
a water input device configured to fill the conditioning tank with water to a water line;
a biomass input device configured to deposit biomass into the conditioning tank, the biomass including a bark portion, a conditioned biomass portion, and a debris portion;
a floating divider which divides the conditioning tank into a first side and a second side, the bark portion of the biomass being contained in the first side of the conditioning tank;
a spillway located on the first side of the conditioning tank, the spillway being configured to transfer the bark portion of the biomass to a bark storage area;
a conveyor comprising:
a first portion below the water line;
and
a second portion above the water line, the second portion being located on the second side of the conditioning tank;
wherein the first portion of the conveyor and the second portion of the conveyor each have a plurality of openings, the plurality of openings being sized to permit the debris portion of the biomass to pass through the conveyor and sink to the bottom of the conditioning tank;
and
a suction filter located on the bottom portion of the conditioning tank.
