Abstract

The present invention relates to a composter being an insulated container into which organic material may be loaded; said container comprising an outer plate of rigid material, an inner plate of material resistant to corrosion and a layer of heat insulating material being located between said two plates; the container being provided with loading and emptying means and suitable openings; and comprising means for rotating and homogenizing the organic material. The composter may be provided with a base and/or with wheels. The invention also relates to a process for composting organic material which comprises the steps of: periodic loading organic materials into the above composter; rotating and homogenizing the organic materials; and incubating the organic materials for a predetermined period.

Claims

1. A composter being an insulated container into which organic material may be loaded;

said container comprising an outer plate of rigid material, an inner plate of material resistant to corrosion and a layer of heat insulating material being located between said two plates;

the container being provided with loading and emptying means and suitable openings; and

comprising means for rotating and homogenizing the organic material.

2. A composter according to claim 1, wherein the container has a cylindrical shape and the plates have the form of sleeves.

3. A composter according to claim 2, wherein the outer sleeve is made of galvanized steel having a thickness of about 1.5 mm.

4. A composter according to claim 2, wherein the inner sleeve is made from a suitable plastic material, e.g. PVC.

5. A composter according to claim 2, wherein the heating insulating material is a layer of foamed polyurethane.

6. A composter according to claim 2, wherein the space between the two sleeves is about 40 mm.

7. A composter according to claim 1, comprising a base.

8. A composter according to claim 7, wherein the base consists of special steel profiles with two special bearings;

a manual rotating handle, and a brake system provided with a locking means.

9. A composter according to claim 7, wherein the composter is connected via the base to a power take-off system connected to a tractor.

10. A composter according to claim 7, wherein the base comprises a motor having the capacity to rotate the composter.

11. A composter according to claim 1, being provided with wheels.

12. A composter according to claim 1, wherein the homogenizing means are loaded within the inner space.

13. A composter according to claim 1, wherein the homogenizing means are, eg. handle bars welded around the steel circumference of the container;

buffles etc.

14. A composter according to claim 1, wherein the loading and emptying means are, e.g. a hatch and the openings are e.g. ventilating holes.

15. A process for composting organic material which comprises the steps of periodic loading organic materials into the composter according to claim 1 rotating and homogenizing the organic materials;
