Vaporizer For Vaporizing A Constituent Of A Plant Material
Apparatus and methods are described for use with a vaporizer that vaporizes at least one active ingredient of a material. In response to receiving a first input to the vaporizer, the material is heated, in a first heating step. An indication of the temperature of the material is detected, and, in response to detecting an indication that the temperature of the material is at a first temperature, the first heating step is terminated, by withholding causing further temperature increase of the material. The first temperature is less than 95 percent of the vaporization temperature of the active ingredient. Subsequently, a second input is received at the vaporizer. In response thereto, the material is heated to the vaporization temperature, in a second heating step. Other applications are also described.

- 1. A vaporizer comprising:
a plurality of capsules, each of the capsules configured to be placed at a vaporization location within the vaporizer, each of the capsules comprising a first mesh, a second mesh, a plant material, and a plurality of spacing elements, the plant material containing at least one active ingredient and disposed between the first mesh and the second mesh, the plurality of spacing elements disposed on the first mesh and the second mesh, the vaporizer shaped to define at least first and second receptacles, the first and second receptacles each being shaped to house the plurality of capsules in stacked configurations; a capsule transfer mechanism configured to individually transfer each of the capsules from the first receptacle to the vaporization location and from the vaporization location to the second receptacle; a temperature sensor configured to measure an indication of a temperature of the plant material without drawing heat from a capsule disposed at the vaporization location; and control circuitry configured to:
vaporize the at least one active ingredient of the plant material by heating the plant material, while the capsule is disposed at the vaporization location, and
control the heating of the plant material, based upon the indication of the temperature of the plant material measured by the temperature sensor.
- 17. A method for use with a vaporizer comprising:
placing one of a plurality of capsules at a vaporization location within the vaporizer using a capsule-transfer mechanism, each of the capsules including a first mesh, a second mesh, a plant material, and a plurality of spacing elements, the plant material containing at least one active ingredient and disposed between the first mesh and the second mesh, the plurality of spacing elements disposed on the first mesh and the second mesh, the vaporizer shaped to define at least first and second receptacles, the first and second receptacles each being shaped to house the plurality of capsules in stacked configurations so as to facilitate individually transferring a capsule from the first receptacle to the vaporization location using the capsule-transfer mechanism; using a temperature sensor, measuring an indication of a temperature of the plant material without drawing heat from the capsule disposed at the vaporization location; and using control circuitry:
vaporizing the at least one active ingredient of the plant material by heating the plant material, while the capsule is disposed at the vaporization location, and
controlling the heating of the plant material, based upon the indication of the temperature of the plant material measured by the temperature sensor; and
individually transferring the capsule from the vaporization location to the second receptacle using the capsule-transfer mechanism.
