TRS value of sugarcane according to bioenergy and sugar levels

In the specific case of sugarcane, producers in Brazil are currently paid by the content of total recoverable sugars (TRS) in the raw material when it reaches the industry, according to CONSECANA: TRS = 9.6316 *PC +9.15 * RSS, where PC is the Pol in cane (apparent sucrose) and RSS are reducing sugars in sugarcane (glucose + fructose). The objective of the project was to propose changes in the procedures used to mathematically determine the TRS, estimating the calorific value of moist cake and weight of moist cake. The final model is then proposed: TRS = 25.9892 + 0.02172*CVmc*WMC+0.536*WMC - 4.14*CVmc + + 4.8158*PC + 4.575*RSS. Thus we obtain the TRS calculated according to the calorific value of moist cake (CVmc), weight of moist cake (WMC), Pol cane (PC) and the reducing sugars in sugarcane (RSS). This form is included in the estimation of TRS, the calorific value of moist cake, which reflects the bioenergy of fiber, weight of moist cake that estimates sugarcane fiber, in addition to existing factors Pol cane and reducing sugars in sugarcane. In the proposed model, the estimated values of TSR were 11.08% higher than the estimated values in the CONSECANA model.

针对甘蔗产业场景，根据巴西蔗糖行业协会（CONSECANA）的规定，目前巴西甘蔗生产商的报酬结算以原料运抵工厂时的总可回收糖分（total recoverable sugars, TRS）含量为依据，其官方计算公式为：TRS = 9.6316*PC + 9.15*RSS，其中PC为蔗茎表观蔗糖含量（Pol in cane），RSS为甘蔗还原糖（葡萄糖与果糖之和）。本项目的研究目标为优化现有总可回收糖分的数学测算流程，同时估算湿滤饼的热值与湿滤饼重量。最终提出的改进测算模型为：TRS = 25.9892 + 0.02172*CVmc*WMC + 0.536*WMC - 4.14*CVmc + + 4.8158*PC + 4.575*RSS。据此，可基于湿滤饼热值（calorific value of moist cake, CVmc）、湿滤饼重量（weight of moist cake, WMC）、蔗茎蔗糖分（PC）与甘蔗还原糖（RSS）计算得到总可回收糖分。该模型将湿滤饼热值（可反映纤维生物质能）与湿滤饼重量（可估算甘蔗纤维含量）纳入总可回收糖分的测算体系，同时保留了原有测算中的蔗茎蔗糖分与甘蔗还原糖两项核心参数。经测算，本模型得到的总可回收糖分估计值较CONSECANA原模型高出11.08%。
