Abstract

A mushroom compost compacting system and method includes a roller assembly mounted to a compost receptacle to form a nip, and a web or conveyor to convey mushroom compost to the nip. Mushroom compost is compacted at the nip from an initial compost height to a final compost height. The roller assembly has a roller, a shaft, and fixtures coupled to each end of the shaft. The fixtures are adjustable to define the roller nip height. In one embodiment, the fixtures are mounted to sleeves that engage the sidewalls of the compost receptacle. In another embodiment, the ends of the fixtures are mounted to a support, which may be a joist or a separate channel extending under the floor portion of the compost receptacle, or which may be a post that forms support structure for the compost receptacle.

Claims

1. A mushroom compost compacting system, comprising:

at least one roller assembly coupled to a compost receptacle having mushroom compost therein, wherein the at least one roller assembly comprises;

a roller adapted for rotation on a shaft;

a first fixture coupled to a first end of the shaft, wherein the first fixture is adapted for height adjustment of the roller and the shaft in reference to a floor portion of the compost receptacle to create a nip between the roller and the floor portion of the compost receptacle, wherein the first fixture comprises;

a first end coupled to the first end of the shaft,

a mid-section coupled to a sleeve, wherein the sleeve is adapted to mount onto a first sidewall of the compost receptacle, and

a second end adapted to mount onto a support of the compost receptacle;

a second fixture coupled to a second end of the shaft, wherein the second fixture is adapted for height adjustment of the roller and the shaft in reference to the floor portion of the compost receptacle, wherein the second fixture comprises;

a first end coupled to the second end of the shaft;

a mid-section coupled to a second sleeve, wherein the second sleeve is adapted to mount onto a second sidewall of the compost receptacle, and

a second end adapted to mount onto the support of the compost receptacle; and

a web adapted to convey the mushroom compost into the nip between the roller and the floor portion of the compost receptacle.

2. The mushroom compost compacting system of claim 1, wherein the nip is from about 6 to about 9 inches.

3. The mushroom compost compacting system of claim 1, wherein the support is a channel member positioned under the floor portion of the compost receptacle, and coupled to the second end of the first fixture and the second end of the second fixture.

4. The mushroom compost compacting system of claim 1, wherein the support is a joist supporting the floor portion of the compost receptacle.

5. The mushroom compost compacting system of claim 1, wherein the support is a post associated with the compost receptacle.

6. The mushroom compost compacting system of claim 1, further comprising a motor coupled to the shaft for rotation of the roller.
