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, comprising:
a cylindrical, elongate smokable material heater including:
a first heater cylinder configured to heat a first region of a smokable material to a volatizing temperature sufficient to volatize a component of the smokable material, wherein the first region of the smokable material is the smokable material located within the first heater cylinder; and
a second heater cylinder configured to heat, concurrently with the first heater cylinder heating the first region of the smokable material, a second region of the smokable material to a temperature lower than said volatizing temperature but sufficient to prevent condensation of volatized components of the smokable material, wherein the second region of the smokable material is the smokable material located within the second heater cylinder, the first heater cylinder and the second heater cylinder being axially aligned, and wherein a combined length of the first heater cylinder and the second heater cylinder is approximately equal to a length of the smokable material.
2. The apparatus according to claim 1 , wherein the apparatus is configured to control the temperature of the first region of the smokable material independently of the temperature of the second region of the smokable material.
3. The apparatus according to claim 1 , wherein the apparatus comprises a controller configured to cause the first heater cylinder to heat the first region of the smokable material to said volatizing temperature and to cause the second heater cylinder to concurrently heat the second region of the smokable material to said lower temperature.
4. The apparatus according to claim 3 , wherein the controller is further configured to subsequently cause the first heater cylinder to heat the first region of the smokable material to said lower temperature and to cause the second heater cylinder to concurrently heat the second region of the smokable material to said volatizing temperature.
5. The apparatus according to claim 1 , further configured to successively heat different regions of the smokable material to said volatizing temperature whilst concurrently heating a region of the smokable material not heated to said volatizing temperature to said lower temperature to prevent condensation of volatized components.
6. The apparatus according to claim 1 , including a smokable material heat chamber disposed within the cylindrical, elongate smokable material heater, the heat chamber sized to contain the smokable material during heating.
7. The apparatus according to claim 6 , wherein the lower temperature prevents condensation of volatized components in the heat chamber.
8. The apparatus according to claim 1 , further comprising a mouthpiece through which volatized components of the smokable material can be inhaled during use.
9. The apparatus according to claim 1 , wherein the volatizing temperature is at least 100 degrees Celsius.
10. The apparatus according to claim 1 , wherein the lower temperature is less than 100 degrees Celsius.
11. The apparatus according to claim 2 , further comprising a controller configured to control the temperature of the first heater cylinder independently of the temperature of the second heater cylinder.
12. The apparatus of claim 11 , wherein the controller is electronically connected to the cylindrical, elongate smokable material heater.
13. A method of heating smokable material by a cylindrical, elongate smokable material heater, comprising:
heating a first region of a smokable material to a volatizing temperature to volatize at least one component of the smokable material for inhalation, wherein the first region of the smokable material is located within a first heater cylinder; and
concurrently heating a second region of the smokable material to a temperature which is lower than the volatizing temperature, but sufficient to prevent condensation of volatized components of the smokable material, wherein the second region of the smokable material is located within a second heater cylinder,
wherein the first heater cylinder and the second heater cylinder are axially aligned, and wherein a combined length of the first heater cylinder and the second heater cylinder is approximately equal to a length of the smokable material.
14. The method according to claim 13 , wherein the volatizing temperature is at least 100 degrees Celsius.
15. The method according to claim 13 , wherein the lower temperature is less than 100 degrees Celsius.
