| In 1761 he proceeded to experiment on the force of steam by means of a small Papin's digester and a syringe. |
| 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. |
| The boiler or digester is filled with dusted rags, and the requisite amount of alkaline solution added. |
| The wood chips are placed in the digester and are cooked in a highly corrosive alkaline solution. |
| However, if the digester solution is too basic, then the acetogenic bacteria population is too low. |
| Professor Junichen recommends the use of the digester for the purpose of boiling meat and other food. |
