Victorian illustration to download showing boys working a large bread-making machine and baking the bread. One boy stands at the top ready to put the flour in the circular mixer, and another sits at the side putting the mixed dough into tins as it emerges from the mixer. Other boys put the bread into the ‘traversing oven’ through which the bread travels on rollers. This was the invention of Dr Dauglish (1824-66, founder of the Aerated Bread Company, ABC) in 1860. The bread was yeast-free – the flour was mixed with water aerated with carbonic acid gas which was pumped into the mixing machine at high pressure. The advantages of his process were hygiene (no kneading with bare hands) and speed (no waiting for the bread to rise).
