The smoke house consists of a chamber into which the sheets are loaded either on trolleys carrying reapers or on reapers fitted on a wooden framework. Smoke is generated in the furnace, which is usually outside the chamber. Smoke and hot air from the furnace are directed into the chamber through a flue. Air inlets and ventilators are provided at the bottom and top of the chamber respectively. These can be opened or closed for controlling temperature. Temperature can also be regulated by adjusting the rate of burning of the firewood by opening or closing the air inlets in the furnace door. A damper is usually provided at the main flue outlet, as a safety measure to prevent fire entering the chamber in an event of opening the furnace door. . The four sides of the chamber may be filled with glass wool. The smoke house shall be provided with adequate drainage to facilitate removal of serum dripping from the sheets. The roof and the ceiling may be of asbestos sheets and the gap between the roof and the ceiling at the top of the walls shall be closed from all the four sides of the smoke house, so as to avoid heat loss due to air currents over the ceiling and to prevent condensed moisture containing carbon from dripping on sheets. Smoke houses are of two types, those in which the furnace is inside the drying chamber and those in which the furnace is outside.
