The system consisted of three parts: conditioned air input, grain respiration column, and moisture and carbon dioxide absorption columns. The system was tested for maximum loading rates (r_(CO_2)^*), minimum residence times (RT), capacities (A_(H_2 O), A_(CO_2 )) and efficiencies (η_(H_2 O), η_(CO_2 )) of moisture and CO2 absorption columns. A pair of preliminary tests with 14% moisture soybeans at 35°C was conducted to demonstrate how to estimate respiration rate (r_(CO_2 )) and DML rate (rDML). Results showed that moisture absorption columns had A_(H_2 O) = 21 g, no minimum RT and overall η_(H_2 O) = 0.96 ± 0.07 when flow rate, Q = 200 to 2000 ml/min. Similarly, the CO2 absorption columns had A_(CO_2 )= 12.6 g with r_(CO_2)^*= 2.1 g/h, minimum RT of 5.4 s and overall η_(CO_2 )= 0.99 ± 0.01 when 〖MC〗_ad ≥ 11.27%. Results from a soybean respiration test showed a r_(CO_2 )= 15.7 mg/(kg·h) and rDML = 0.010%/d, which were comparable to rates reported by Rukunudin et al. (2004). Compositional analysis showed changes in soluble protein, FFA and mold counts may be significant even after 4-5 d of storing 14% moisture soybeans. These results showed the system may be used to evaluate a wide range of respiration and DML rates for various oilseeds, cereal grains, and other agricultural or food products.","abstract_html":"A respiration measurement system was designed, fabricated and tested to estimate dry matter loss (DML) of soybeans through monitoring carbon dioxide (CO2) from grain respiration by gravimetric analysis.
