The proper time and temperature for dry heat sterilization is 160 °C (320 °F) for 2 hours or 170 °C (340 °F) for 1 hour, and in the case of High Velocity Hot Air sterilisers, 190°C (375°F) for 6 to 12 minutes. [3] Items should be dry before sterilization since water will interfere with the process.

The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.
Dry heat sterilizer. Dry heat was the first method of sterilization and is a longer process than moist heat sterilization. The destruction of microorganisms through the use of dry heat is a gradual phenomenon. With longer exposure to lethal temperatures, the number of killed microorganisms increases.
Braising – combination cooking method using both moist and dry heat; typically the food is first seared at a high temperature and then finished in a covered pot with a variable amount of liquid, resulting in a particular flavour. Coddling – food is heated in water kept just below the boiling point.
Braised ox cheek in star anise and soy sauce. Braising (from the French word braiser) is a combination-cooking method that uses both wet and dry heats: typically, the food is first browned at a high temperature, then simmered in a covered pot in cooking liquid (such as wine, broth, coconut milk or beer).
Abnormally warm temperatures, dry grasses, and a sudden windy cold front combined to create the conditions for the destructive wildfires that have raged across parts of Texas this week.
Sweating is an effective heat loss mechanism that relies on evaporation from the skin. However at high RH, the air has close to the maximum water vapor that it can hold, so evaporation, and therefore heat loss, is decreased. On the other hand, very dry environments (RH < 20–30%) are also uncomfortable because of their effect on the mucous ...
