carbonized rice hull making

1. CARBONIZED RICE HULL (CRH)

2. CARBONIZED RICE HULL Carbonized rice hull (CRH) is made from incomplete or partial burning of rice hull. It is porous and bulky with uniform intact black particles. It contains phosphorous (P), potassium (K), calcium (Ca), magnesium (Mg), and micronutrients vital to growing crops. Because it is also sterilized, it is free from disease organisms.

3. USES OF CRH 1. As substrate to organic fertilizer When mixed with other organic materials like bokashi, CRH can be a good source of organic fertilizer (OF)

4. USES OF CRH As soil conditioner Makes the clay soil porous Replenish nutrients and other microelements in the soil that were lost due to continuous cropping. Improves soil structure by increasing bulk density, water holding capacity, and aeration. It is a good potting media when mixed with other materials

5. USES OF CRH As water purifier Activated carbon from CRH filters the dirty particles in water, making it effective in purifying household/drinking water.

6. USES OF CRH 4. As base material for making microbial inoculants, Effective Micro Organisms(EM) When 30-50% of CRH is mixed with EM Bokashi , it becomes more useful. Naturally, CRH is a habitat for beneficial micro organisms that facilitate composting. CRH can be used as inoculant-carrier for rhizobia, a nitrogen-fixing bacteria found in the roots of legumes

7. USES OF CRH 5. As Pest Control Agent Contains silica that irritates the golden kuhol. When applied after leveling, snails are forced to come out, making handpicking faster and easier.

8. USES OF CRH As charcoal for fuel Charcoal briquettes from CRH are good alternative sources of fuel. Compared with plain rice hull that takes relatively more time to produce heat, CRH can easily be ignited to produce heat or convert heat into fuel for cooking

9. USES OF CRH 7. As deodorizer / odor suppressant CRH also cleanses and deodorizes bad air smell through its activated carbon that absorbs foul odors in the air. The same principle applies when a charcoal is placed inside a refrigerator. CRH is used as mulch bed in animal pen and poultry houses to reduce foul smell from urine and manure

10. MAKING OF CARBONIZED RICE HULL (ANG PAGGAWA NG CARBONIZED RICE HULL)

11. Dry RICE HULL Carbonizer S h o v el Watering pale Fire wood (fuel) Lighter or match sticks

12. STEP 1 Start a fire using the lighter and firewood and let it kindle

13. STEP 2 Make sure that the fire won’t die out before covering it with the Carbonizer

14. STEP 3 Pour and stack the dried rice hull around the carbonizer.

15. STEP 4 When the rice hull at the top are carbonized, use the shovel to cover it with the dried rice hull from the bottom

16. STEP 5 When the rice hull is almost carbonized (80%). Remove the carbonizer by tipping it over to the side using the long shovel. Extra caution is exercised for the carbonizer is extremely hot

17. STEP 6 Mix the rice hull and let the remaining embers to carbonize the rest of the mixture until all of it (100%) are carbonized

18. STEP 7 W he n a l l o f the rice hull spr i nkle a r e c a r boni z ed, w a t e r o n t o the t h e w a t e ring CR H us i ng pale t o e xtingui s h the remaining embers

19. STEP 8 Lay the CRH thinly and make sure that the embers have died out to prevent the carbonized rice hull turn to ash

20. STEP 9 When its dry, collect and store the CRH into sacks. After that, its ready to be used or sold

21. How to fabricate your own carbonizer?

22. FOR THE CHAMBER: Get any 20 L used oil can, about 40 cm height. Remove the top cover and make a hole at the bottom of the can about9-10 cm diameter for the chimney

23. Alternative: Make use of defective pressure tanks. Cut in half to make two carbonizers.

24. Use a metal puncher to make 30- 40 holes at 2-cm diameter aligned at 12 x 20 cm distance

25. A L TERN A TIVE Use welding rod to make holes

26. FOR THE CHIMNEY From the junk shop, buy used GI Pipe Size: 5 to 6 feet high and 3 inches diameter

27. To make it more sturdy, Install metal braces

28. T o la s ts f or years, Install additional metal braces
