digester

The farm plans to utilize an anaerobic digester to gather waste such as left-over plant roots to generate power.

Ben, my fine fellow, put your hand into the cupboard, and bring out the patent digester.'

The boiler or digester is filled with dusted rags, and the requisite amount of alkaline solution added.

For this purpose a spherical digester is used, generally 7-9 feet diameter, and capable of holding 2-2 tons of rag.

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.
