Drying is considered one of the industrial processes that requires more energy than other processes, being a topic of much interest to the agricultural sector, especially the evaluation of energy consumption for rice and corn dryers. To meet this goal, an overview survey matrix and protocols for temperature measurements of dryers were developed. The study evaluated 49 rice dryers and 14 yellow corn dryers. As a result, it was determined that the oversizing of the fan/extractor and the dryer engine generates a high energy consumption, added to the lack of insulation in the heat ducts. Therefore, the drying productivity index is very low in dryers using liquefied petroleum gas (LPG) being 0.14 dollar/quintal for rice and 0.27 dollar/quintal for corn and using biomass reaches 1.4 dollars/quintal. In relation to energy losses, these account for more than 55%. Inadequate energy management in drying processes directly influences the marketing chain of products, the losses of which are caused by fluctuations in the price of rice and corn on the domestic market, with the agricultural sector having to generate an energy efficiency plan.

赤道区水稻和玉米干燥过程的能耗估算

干燥被认为是比其他过程需要更多能量的工业过程之一，这是农业部门非常关注的话题，尤其是稻米和玉米干燥机的能耗评估。为了实现这一目标，开发了概述调查矩阵和干燥机温度测量协议。该研究评估了49台水稻烘干机和14台黄色玉米烘干机。结果，确定了风扇/抽气机和烘干机发动机的尺寸过大会产生高能量消耗，这加之热导管中的绝热不足。因此，使用液化石油气（LPG）的干燥机的干燥生产率指数非常低，大米为0.14美元/公担，玉米为0.27美元/公担，而使用生物质能达到1.4美元/公担。关于能量损失，这些占了55％以上。干燥过程中的能源管理不足直接影响产品的销售链，其损失是由国内市场上大米和玉米价格的波动引起的，而农业部门必须制定能源效率计划。
