Methods include immersion in tanks of hot water or spraying with steam. The scalding may be hard or soft, in which the temperature or duration is varied. A hard scald of 58 °C (136.4 °F) for 2.5 minutes will remove the epidermis of poultry; this is commonly used for carcasses that will be frozen, so that their appearance is white and attractive.
In general, a pig scalder looks like a very large pot or tub. It would be made of wood or metal, though a metal scalder allowed users to build a fire underneath in order to heat the water inside. In New Zealand , many farmers use their old cast iron bathtubs for this job, but the tubs are becoming harder to acquire.
More than one stub template may be used, if necessary, though no more than four should be used on any article. Place a stub template at the very end of the article, after the "External links" section, any navigation templates, and the category tags. As usual, templates are added by including their name inside double braces, e.g. {{Domestic-pig ...
Warm-blooded is a term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals) maintain a stable body temperature by regulating metabolic processes. Other species have various degrees of thermoregulation.
After the material is tanked, the free fat is run off, the remaining water ("tank water") run into a separate vat, and the solids removed and dried by pressing and steam-drying in a jacketed vessel. The tank water was either run into a sewer or it was evaporated to make glue or protein concentrate to add to fertilizer. The solids were used for ...

The storage of water at high temperature removes one possible breeding ground for Legionella; the use of a thermostat, rather than a static mixing valve, provides increased safety against scalding, and increased user comfort, because the hot-water temperature remains constant. [1] Many TMVs use a wax thermostat for regulation. They also shut ...
After the soak segment, the profile enters the ramp-to-peak segment of the profile, which is a given temperature range and time exceeding the melting temperature of the alloy. Successful profiles range in temperature up to 30 °C higher than liquidus, which is approximately 183 °C for eutectic and approximately 217 °C for lead-free.
