Bulk operations look more like a chemical plant with stainless steel plumbing and a relatively short residence time in the winery. (inc.com)
These analyses indicate that it is likely that greenhouse gases alone would have caused more than the observed warming over the last 50 years of the 20th century, with some warming offset by cooling from natural and other anthropogenic factors, notably aerosols, which have a very short residence time in the atmosphere relative to that of well - mixed greenhouse gases (Schwartz, 1993).

The partial vacuum and short residence time within the Vaction ™ unit prevents the exposure of ingredients to excess temperatures, in turn, preventing contact with the kettle's surface which can burn and affect the finished product's flavour and visual quality. (steaminfusion.oalgroup.com)
