During the composting process, waste biomass with high moisture content undergoes various transformation in the presence of oxygen. The composting process is analyzed in dedicated bioreactors which are air-tight facilities with external air supply. Subject to the type of composted plant material, biomass should be periodically turned to promote even aeration. The following information is required to build a model of the composting process: oxygen (air) uptake, moisture content of exhaust gas, production of carbon dioxide, ammonia and other gases in the composting process, and temperature distribution inside the bioreactor. A temperature monitoring system for a bioreactor is difficult to build due to challenging operating conditions including the airtight structure of a bioreactor, high moisture content, the operation of temperature sensors in a highly aggressive environment, problems with uninterrupted power supply for the monitoring system in a bioreactor. This article presents a patented temperature monitoring system for a bioreactor. The system’s design and structure are discussed, and recommendations for functional improvements are made.
