Machine for Raising Dough at Messrs. Carr and Co.'s Works, Carlisle, 1857. 'The process which has just been perfected by Dr. Dauglish, after a long series of experiments...effects the raising of bread with absolute purity and certainty...Dr. Dauglish has conceived the idea of raising dough with water which has been made to absorb the requisite quantity of gas to render the dough light...This machine...consists of a strong iron globe, inside of which are properly-constructed kneading-arms, worked by steam power. Close to this globe, and raised above it, is a copper cylinder or condenser, and behind these is a set of three pumps, worked also by steam power...The gas, which was held in the water by the pressure, leaves it, and in so do doing expands the dough into a most beautiful, spongy, elastic mass, occupying about five or six times the space that it did previously'. From "Illustrated London News", 1857.
