Biochar machine for treating rice straw bales

Abstract

Biochar machine includes a sealed container for rice straw bales with two gates. The top gate is for rice straw feeding and the bottom gate for Biochar. The Biochar unit is equipped with a stirrer operated by an electric motor and a speed reduction unit. The Biochar unit is operated indirectly through a combustion chamber with a fuel burner to heat the sealed container from all sides indirectly. The gases produced as a result of heating the rice straw are collected and returned back to the combustion chamber through a blower.

1 - 3 . (canceled) 
     
     
         4 . A biochar machine comprising:
 a sealable charring processing tank ( 1 ) for receiving and charring rice straw bales;   an agitator ( 4 ) positioned in said sealable charring processing tank ( 1 ), said agitator ( 4 ) configured to grind rice straw inside said sealable processing tank ( 1 ); and   a water sprayers ( 7 ) positioned in said sealable charring processing tank ( 1 ) and configured to spray water inside said sealable processing tank ( 1 ).   
     
     
         5 . The biochar machine according to  claim 4 , wherein said sealable charring processing tank ( 1 ) has an opening in a lower part for exiting biochar said sealable charring processing tank ( 1 ) and an opening in an upper part for receiving said rice straw bales. 
     
     
         6 . The biochar machine according  claim 4 , further comprising a combustion unit comprising a burner ( 5 ) for burning fuel adjacent to said sealable charring processing tank ( 1 ) in order to heat the rice straw air free, from all directions. 
     
     
         7 . A method of forming biochar from rice straw bales comprising:
 introducing rice straw bales into the biochar machine according to  claim 4  that comprises a sealable charring processing tank by placing rice straw bales, without cutting, inside said sealable charring processing tank;   sealing said sealable charring processing tank and subjecting said rice straw to a charring process to form biochar;   grinding said rice straw during the charring process;   cooling said biochar by spraying water into said sealable charring processing tank.   
     
     
         8 . The method according to  claim 7 , wherein said charring process comprises heating said rice straw in air-free using a burner for burning fuel adjacent to said sealable processing tank in order to heat the rice straw air free, from all directions.
