黄酒前酵自控系统的研究与应用

Research and Application of the Automatic Control System for Pre-fermentation Process of Yellow Rice Wine

针对目前黄酒生产过程仍以手工操作为主,且存在生产规模小、自动化程度低和批次稳定性差等问题,对黄酒发酵工艺进行了研究。结合LabVIEW、S7-300 PLC以及相关传感器和智能仪表等技术,提出黄酒前酵自控系统的软硬件总体方案,并分析了相关功能模块的原理及操作步骤。最后成功地将该方案应用于绍兴女儿红酒厂前酵生产过程中,达到了预期效果。实测结果验证了该系统的正确性和可行性,对推广黄酒发酵的自动化有着重要意义。

In accordance with the current conditions in production of yellow rice wine, e. g. , manual operation, small scale and low automation level, as well as poor stability in batches ; the ferment process of the wine is studied. Combining with LabVIEW, S7-300 PLC and related technologies of sensor and intelligent instrument, the overall strategy for the hardware and software of pre-fermentation automatic control system is proposed; the principle and procedures of related functional modules are analyzed. This strategy has been successfully applied in Shaoxing Nverhong Brewery and reaches predictive effects. The result of practical test verifies the correctness and feasibility of the system ; it is significant for popularizing automation of yellow rice wine production.
