“…The dry weight of the uncovered corncob pile decreased more than that of the covered pile. According to del Campo et al (2014), this was related to the biological activity and moisture content when an LDPE sheet was used to cover the pile. The sheet helped reduce environmental disturbances to the pile, such as fluctuations in air temperature, rainfall, and ambient humidity (Fig.…”

In order to determine optimal conditions for maintaining biomass quality during storage, an analysis was conducted to investigate the changes in biomass characteristics in Bangkok, Thailand. The study focused on three types of biomass: corncob, woodchip, and bagasse, which are valuable renewable energy resources in the region. Each type of biomass was divided into two separate piles: one covered with a plastic sheet and the other left uncovered. Over a storage period of seven months (February-September), various characteristics of the biomass piles were evaluated, including pile temperature, moisture content, ash content, heating value, and dry matter loss. The findings indicate that the utilization of plastic sheets significantly enhanced the quality of corncob and woodchip biomass. This improvement was attributed to reduced moisture content, leading to higher heating values, lower ash content, and decreased dry matter loss in the covered piles compared to the uncovered ones. However, such improvements were not observed in the case of bagasse, as its quality exhibited fluctuations throughout the study period.

“…Слід зауважити, що всі відомі прийоми енергозаощадження були спрямовані лише на техніко-технологічну модернізацію камерних зерносушарок без заміни виду палива. Принципово іншим напрямом економії енергоматеріалів є використання рослинних видів палива (стрижні кукурудзи, солома, соняшникове лушпиння, щепа, пелети) та створення теплогенераторів для їх спалювання (Del Campo et al, 2014). Останнім часом в Україні та за її межами пропонуються різні теплогенератори для спалювання біомаси потужністю 0,5-5,0 мВт, проте не всі вони придатні для сушіння насіннєвої кукурудзи в качанах (табл.…”

In the process of post-harvest processing of corn seeds, the thermal drying of wet cob is the most energy-efficient operation. It depends on the value of the produce-the seeds and its competitiveness on the market. Today, the problem of energy saving becomes more relevant in connection with a significant increase in prices for energy materials, the cost of which is about 90% of all costs for the drying process. Different technical and technological methods of energy saving during drying of corn seeds, such as two-stage drying of cobs with pre-drying in grain, return of exhaust coolant to the drying zone (recirculation), application of the maximum allowable heating temperatures of the cavities (intensive drying) are investigated. The most practical value is the reversing and recycling of coolants, which reduce fuel consumption by 20-26%, fully preserve the quality of the seeds, do not require significant technical re-equipment of chamber corn dryers. The new method of energy saving based on the use of TPG heat generators working from corn cobs burning is determined and investigated. The technical and technological indicators of the operation of chamber corn dryer in the complex with the new heat generator TPG are investigated. The temperature regime corresponded to normative parameters and fluctuated within 38-43 °C. The ventilation regime under which the drying took place depended on the mode of access of air to the fuel and ventilation compartment. Full air access provided a specific airflow at the level of 1393 m 3 /h per 1 tonne of boilers satisfying the norm of 800-1000 m 3 /h. Relative humidity of the working hot air during the entire drying process was 10-12%. In experiments, the drying rate fluctuated within the range from 0.16-0.39%/h, the performance of one chamber-1.2-6.0 t-%/h, depending on the weight of the cobs, their humidity and exposure of drying. Drying on the energy-saving complex did not have a negative impact on the quality of corn seeds. Laboratory similarity of the studied hybrids was 95-98%, which corresponds to normative indexes. The yield of seeds dried in the energy-saving complex was at the control level, and in some cases exceeded it. Control was provided by seeds dried in a laboratory dryer at 39 °C with forced circulation of air and in premises at 20-25 °C. The economic efficiency of the new drying method is determined. The total cost of drying maize cobs with different types of fuel is diesel 1145 UAH/t, gaseous-665 UAH/t, corn cobs-250 UAH/t. In general, the use of new heat generators does not have any negative effect on the technological process of drying-its duration, dynamics and uniformity of drying of the cobs.
