Heating smokable material
An apparatus comprising a smokable material heater, configured to heat a first region of smokable material to a volatizing temperature sufficient to volatize a component of smokable material and to concurrently heat a second region of smokable material to a temperature lower than said volatizing temperature but which is sufficient to prevent condensation of volatized components of the smokable material. A method of heating smokable material is also described.
1. An apparatus for heating smokable material comprising:
a housing comprising an opening through which smokable material may be inserted; and
a heater located in a central region of the housing configured to heat the smokeable material contained within the apparatus in use to volatilize at least one component of the smokeable material;
the heater comprising a plurality of independently operable individual heating regions aligned with each other along a longitudinal axis of the heater, wherein each heating region comprises a cylinder; and
a smokeable material heating chamber located outwardly of a longitudinal external surface of the plurality of individual heating regions for containing the smokable material during heating, wherein a length of the heater approximately corresponds to a whole length of the smokable material, and wherein the plurality of independently operable individual heating regions are arranged such that, during heating, each heating region independently heats a corresponding section of the smokable material that is located radially outwardly of the respective heating region.
2. An apparatus according to claim 1 , wherein the heater is elongate.
3. An apparatus according to claim 1 , wherein the heating regions are operable separately and independently to concurrently heat different regions of the smokable material to different temperatures.
4. An apparatus according to claim 1 , wherein the heating regions are operable separately and independently to heat different regions of the smokable material at different times.
5. An apparatus according to claim 1 , further comprising thermal insulation located co-axially around the heating chamber.
6. An apparatus according to claim 1 , wherein the housing comprises an approximately cylindrical tube with an energy source located towards a first end of the housing and the heater and the heating chamber located towards an opposite, second end of the housing.
7. An apparatus according to claim 1 , comprising a mouthpiece through which volatized components of the smokable material can be inhaled.
8. An apparatus according to claim 1 , wherein the apparatus is configured to heat the smokeable material without combusting the smokeable material.
9. An apparatus according to claim 1 , wherein each cylinder comprises a solid disk.
10. An apparatus according to claim 1 , further comprising smokeable material to be received in the apparatus.
11. A method of heating smokeable material to volatilize at least one component of the smokeable material for inhalation, comprising heating the smokeable material by the apparatus of claim 1 .
12. An apparatus for heating smokable material comprising:
a housing;
a heater located in a central region of the housing configured to heat the smokeable material contained within the apparatus in use to volatilize at least one component of the smokeable material, wherein the heater comprises a plurality of independently operable individual heating regions aligned with each other along a longitudinal axis of the heater;
the housing comprising an opening through which smokable material may be inserted in use onto the heater, wherein used smokable material may be slid away from the heater following use; and
a smokeable material heating chamber located outwardly of a longitudinal external surface of the heater for containing the smokable material during heating, wherein a length of the heater approximately corresponds to a whole length of the smokable material, and wherein the plurality of independently operable individual heating regions are arranged such that, during heating, each heating region independently heats a corresponding section of the smokable material that is located outwardly of the respective heating region.
13. An apparatus for heating smokable material comprising:
a housing; and
a smokable material heating chamber located outwardly of a longitudinal external surface of a heater for removably receiving the smokable material during heating;
wherein the heater is located in a central region of the housing and is configured to heat the smokeable material contained within the apparatus in use to volatilize at least one component of the smokeable material, wherein the heater comprises a plurality of independently operable individual heating regions aligned with each other along a longitudinal axis of the heater, wherein the plurality of independently operable individual heating regions are arranged such that, during heating, each heating region independently heats a corresponding section of the smokable material that is located outwardly of the respective heating region, and wherein a length of the heater approximately corresponds to a whole length of the smokable material, and wherein the length of the heater is approximately 50 mm.
