Process for the production of alimentary smoke by pyrolysis, the use of means particularly adapted to said process, smoke and smoked foodstuffs obtained

A method for the production of liquid smoke adapted for smoking agro-food products, said method comprising:

• introducing a vegetable material containing organic material in a pyrolysis reactor comprising a first end for introducing said vegetable material, said pyrolysis reactor comprising a substantially hermetically sealed heatable chamber containing at least one rotatable endless screw for moving said vegetable material through said pyrolysis reactor;
• pyrolyzing said vegetable material at a pyrolysis temperature of between 300 and 380° C. in the pyrolysis reactor;
• and
• recovering the liquid smoke produced by pyrolyzing said vegetable material from said pyrolysis reactor.

A method for the production of liquid smoke adapted for smoking agro-food products, said method comprising:

• introducing a vegetable material containing organic material in a pyrolysis reactor comprising a first end for introducing said vegetable material, said pyrolysis reactor comprising a substantially hermetically sealed heatable chamber containing at least one rotatable endless screw;
• pyrolyzing said vegetable material at a pyrolysis temperature of between 300 and 380° C. in the pyrolysis reactor by heating by Joule effect said rotatable endless screw in rotation;
• discharging the consumed vegetable material from a second end of said pyrolysis reactor;
• and
• recovering the liquid smoke produced by pyrolyzing said vegetable material from said pyrolysis reactor.

A method for the production of thermally modified wood chips, wherein said thermally modified wood chips are produced by:

• introducing a wood chips containing organic material in a pyrolysis reactor comprising a first end for introducing said wood chips, said pyrolysis reactor comprising a substantially hermetically sealed heatable chamber containing at least one rotatable endless screw for moving said wood chips through said pyrolysis reactor;
• pyrolyzing said wood chips at a pyrolysis temperature of between 300 and 380° C. in the pyrolysis reactor;
• and
• recovering the thermally modified wood chips produced by pyrolyzing said wood chips from said pyrolysis reactor.
