  • the smoke and odors are kept inside the container.
  • the temperature control allows specific temperature profiles for different woods, herbs, incents and spices, etc.. Due to the small size of the surface heated by the heater 46, the container 52 keeps cool to the touch.
  • the surrounding temperatures inside the oven cavity 6 can be controlled independently from the smoking or aromatic vapour treatment container temperature (the temperature of the heater 46) using the oven heaters and sensors.
  • the smoking or aromatic vapour treatment process as such allows fast heat-up and fast cool-down. Therefore the smoking or aromatic vapour treatment needs less preparation and a short time.
  • the temperature at the food or the heat transferred to the food is lower as compared to other processes. Avoidance of high temperatures allows producing of sour smoke aromas that would give negative taste results at higher temperature. According to heater temperature selection, the above solution gives the possibility to do both, hot and cold smoking or aromatic vapour treatment.
  • the temperature range that can be set via the input panel 12 and the control unit 82 is for example in the range of 120°C to 400°C, which is convenient for most smoking or aromatic vapour treatment agents and processes.

  • the smoking or aromatic vapour treatment agent surface heated by the heater is for example about 200 cm 2 to 400 cm 2 - e.g. if wood dust is distributed 1 mm thin.
