A saute trace, and why sauteing is never left alone

Sauteing is a pan surface at 150 to 210 degC, with continuous attention and two hazards named in the vocabulary. The trace check is the same as for any envelope; the attention rules are what make a robot ask for a person.

Pasos

  1. The pan warms to 165, 180 and 190 degC: inside the band. checkEnvelope

  2. It climbs to 215 degC: that is searing temperature, outside the saute band. checkEnvelope

  3. A pan that reached 140 degC never got hot enough to saute. checkEnvelope

  4. The vocabulary says it may not run unattended, needs continuous attention, and names hot oil burns and pan fire as hazards. getOps

Resultado

You can read a pan log against the band and you know why a robot refuses to saute when nobody is home (scenario 011). Next: scenario 025 shows what happens when a recipe asks for a temperature outside the band.
