The Characteristics of Production Process and the Designning of Automatic Blending System of the Traditional Chinese Spirit

摘要

The Production process of the traditional Chinese spirit is substantially different from beer brewing. Traditional Chinese spirit is produced with sorghum as main raw materials, and mold-based koji as the glycosylation and fermentation agent. The intense-flavor type spirit is an exotic flower in traditional Chinese spirit. It’s brewing is an extremely complicated process named continuous slag fermentation. It is characterized by simultaneous steaming and distillation of the mixture of fermented grains and fresh raw materials, and repeated glycosylation and fermentation of the steamed feedstock in solid state in the mud pit. Due to the complexity of the fermentation micro flora and their metabolites, the flavor compositions in the spirit produced from different batches are large different. The proportion of various chemicals in the spirit is large different. This necessitates the development and application of automatic blending system which can improve the blending efficiency and consistency of product quality of the traditional spirit. The automatic control system of brewing and blending is convenient for the production optimization analysis of technologists and provides a strong guarantee for exploring the optimal production parameters. Today most large scale distilleries begin to use the automatic blending control system to improve production efficiency and production capacity.
