上甑速度与曲酒产质量关系的研究

Study on the Relationship between Feeding Speed for Distillation and the Yield & the Quality of Liquor

在浓香型大曲酒生产中,蒸馏操作非常重要,俗话说":造香靠发酵,提香靠蒸馏",而上甑是蒸馏过程的重要操作,上甑技术的好坏直接关系到出酒率的高低和曲酒质量的优劣。通过对上甑速度与曲酒产质量的关系研究,采取以上甑蒸汽压力控制上甑速度的方法,得出最佳上甑速度的上甑蒸汽压力为控制在0.045～0.055 MPa范围内,上甑时间控制在40～45 min范围内。

Distillation operation is very important in the production of Luzhou-flavor Daqu liquor. As the saying goes, ＂Fermentation produces aroma but distillation strengthens the aroma＂. As an important operation procedure in distillation, feeding speed for distillation would directly influence liquor yield and liquor quality. Based on the research on the relationship between feeding speed and the yield ＆ the quality of liquor, feeding speed was regulated according to steam pressure. The optimum feeding speed was summed as follows： steam pressure controlled within the range of0.045-0.055 MPa and feeding time controlled within the range of40-45 min.
