The boiler or digester is filled with dusted rags, and the requisite amount of alkaline solution added.
As a digester, Maurice Levy would have disappointed a Borgia.
Professor Junichen recommends the use of the digester for the purpose of boiling meat and other food.
In 1761 he proceeded to experiment on the force of steam by means of a small Papin's digester and a syringe.
A new discovery by a French doctor named Papin of a ‘digester’ for softening bones, caused much discussion at the Society.
His action lasted so long that his digester was filled while his heart was freed of gall.
The clean grass is conveyed by travelling belts to the digester house.
In England the same is commonly effected in an iron Papins digester.
By this means the straw is softened and reduced in bulk, so that a larger quantity can be added before the digester is quite full.
There should also be a small tube or hole covered with a weighted valve to prevent the danger of bursting the digester.
