The given illustration details the structure and operation of a home smokery.
As shown in the diagram, the process involves four steps that can be grouped into two main stages: initial preparation and product completion. Specifically, the process begins with fresh air entering the system and ends with the smoke being absorbed by the food, giving it a smoked flavor.
At the outset, three underground chambers are constructed, with two of them covered by lids while the last one remains open. The first chamber, with its lid open, allows fresh air to enter the system. The second chamber, which is sealed, contains a fire that is ignited and sustained by the airflow from the first chamber. This setup ensures that the fire burns consistently, producing smoke that travels through a pipe connected to the third chamber.
In the final stage, the smoke flows into the third chamber, where the food is hung inside a box. The food absorbs the smoke as it circulates within the chamber, resulting in the distinct smoked flavor. This process demonstrates how the components of the smokery work together to produce smoked food efficiently.
