A model of heat exchange and accumulation in small-sized bioreactors during ethanol fermentation

This paper presents a mathematical model of heat production, exchange and accumulation during ethanol generator at small-scaled fermentor tanks in home wineries or breweries. Heat generation is directly related to CO2 production rate, which serves as a time-dependent input parameter of the model, as well as the actual ambient temperature. Validation at pilot scale experiments showed good agreement with recorded temperature sensor data.
