Solar Dehydrator Working Principle

  1. The solar dehydrator is black in color to absorb the maximum amount of sunlight.
  2. The inclination of the solar dehydrtor allows the moist lighter air to escape from the top.
  3. The dry air is fed in from the vents at the bottom of the box.
  4. In direct sunlight the contents of the box is heated up and releases moisture in the air.
  5. This moist air rises to the top and escapes out from the vents leaving dry air behind.
  6. Over time this process is repeated and slowly the contents of the box get dehydrated.

1 Dry Bones in Sun for 15 days

  1. Collect the bones from your kitchen scraps and place them in a solar dehydrator for 15 days.
  2. If you do not have a solar dehydrator you can use an oven or an electric dehydrator or even a pressure cooker.
  3. By dehydrating the bones it becomes brittle and is easy to crush into a powder.

2 Manually Break Bones to Small Size

  1. Once the bones are dehydrated bring them inside and cover them with a plastic sack
  2. Cush the bones into smaller pieces using stones
  3. Then open the plastic sac and check for any large bone fragments
  4. Use the stones to break them into smaller pieces
  5. You can also use mortar and piston to break them into smaller chunks

3 Crush Bones to Powder Using Grinder

  1. Using an electric blender crush the bones into fine powder.
  2. Make sure not to add too many bone pieces at once to prevent motor overload.

4 Filter Crushed Bone to Get Bone Meal

  1. To make a fine bone meal powder use a metal mesh to filter out the larger bone fragments.
  2. Then again crush the coarse bone powder to get a fine powder.
  3. Repeat the steps till all your bones have been crushed to a fine powder.
