NOVELTY - The method involves allowing rotation of a vertical slicer shaft (6) in vertical plane of bottom constraint. A worm harvester device is attached, to harvest worms via an opening in side of compost house, where width dimension of worm harvester device opening is 0.2 times of total circumference of compost house. The worm harvest door (7) is hinged from vertical side of compost house, to prevent light or air entered or escaped into the compost house. The door is hinged from vertical side of the compost house, so as to secure door in closed position and opened position.    USE - Method for preparing composted material in portable composting device used for composting domestic food waste and commercial kitchen waste, installed in residential lots and special environments. Can also be used in apples, apple peels, baked beans, banana peels, biscuits, cabbage, cake, celery, cheese, corn bead, cream cheese, cream of wheat, cucumber, devilled eggs, egg shells, farina, grapefruit, grits, lemon, lettuce, molasses, oatmeal, onion peel, orange peel, pancake, pears, pine apple, pizza crust, potatoes, potato salad, Ralston, tea leaves, tomatoes and turnip.    ADVANTAGE - The compact upright compost preparing apparatus can be obtained. The household food waste and commercial kitchen waste can be composited easily so as to provide the nutrition to the indoor and outdoor plants. The earthworm number can be increased to enable commissioning of compost maker products. The compost maker can be enabled easily to continually accept food waste through an opening at the top of the compost maker by continually removing composted material with a commonly mechanical ejector installed without impeding on worm activity. The burden of the user can be eliminated.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) the top cover device (1) has a cylindrical covering unit that covers the top opening of the compost house in the horizontal plane. The walls are located at the same vertical disposition from the vertical compost house. An entrance diameter is formed to fit over the top of the compost house with holes around the perimeter of the cylindrical compost house vertical wall (8), where the hole diameter is formed without exceeding 1/10 of the compost house diameter. The compost house with fine mesh, is arranged around the perimeter of the cylindrical vertical wall;    (2) slicer device has a vertical slicer shaft that is provided with sufficiently strong characteristics material elements in a vertical position in the compost house, and is supported vertically by the top support. A bottom support is constrained horizontally by the top constraint and bottom constraints. A horizontal orientated turning shaft with sufficiently strong characteristics material elements, that is attached and secured to the top of the vertical slicer shaft, such that the vertical slicer shaft is turned, when the horizontal turning shaft is rotated in the horizontal plane. A rotating turning handle grip is attached and secured over a vertically orientated turning handle shaft attached and secured at the end of the horizontal shaft. A rotating turning handle grip is rotated around the vertical turning handle, when the rotating turning handle grip is rotated in a horizontal plane to engage the vertical slicer shaft. A horizontal turning handle shaft with rotating turning handle hand grip handle, is attached to the vertical slicer shaft, and is hinged at a point between the vertical slicer shaft and the vertical wall of the compost house, where the hinge allows a vertical swivel of the horizontal turning handle shaft. The length dimension of the horizontal turning handle shaft with rotating turning handle is longer than the radius of the top of the cylinder of the compost house;    (3) grid device has a horizontal mesh wire apparatus with square opening, that is provided with specific de-composting material characteristics and/or moisture content of the composted material, to allow for de-composted material to fall through the mesh openings out of the compost house. The horizontal mesh wire apparatus is made from a suitable rust free material with no chemical or biological interaction with the de-composting materials, so as to allow for uncontaminated de-composted materials. A horizontal mesh wire apparatus is installed in a circular ring, and is installed onto the stand, such that mesh is removed and replaced with a mesh with a smaller grid size, or larger grid size, depending on the de-composted material structural characteristics;    (4) compost house base stand device has a roof and a floor that is supported by the vertical walls. A horizontal support is formed into the roof part for the compost house vertical walls. A circular rim and seat is provided on the compost house stand roof for the compost house walls. The grid device is locked in a position, when the compost house wall is rest in the direction of gravity on the grid device;    (5) compost collection tray device (14) has a floor unit which supports the vertical walls for the compost collection tray with sufficiently strong characteristics material elements. A vertical support for compost collection tray vertical walls is connected to the vertical wall to each other in the vertical corners of sufficiently strong characteristics material elements. A grip unit pulls the compost collection tray out from the compost house base stand (13); and    (6) glass beads device has spherical brightly colored glass is provided with other chemical inactive, rust free, fade free, color fast and strong characteristics material elements. The spherical bead is provided with preset diameter, and is provided with different colors of spherical beads.
