Energy-saving and water-saving yellow wine production device

Abstract

Traditional yellow wine production relates to extremely complicated technical processes such as rice soaking, rice steaming, cylinder filling, yeast adding, fermentation, filtering, boiling and ageing, during which large amounts of labor is required for transporting materials from one container to another, the rice soaking process can produce a large amount of rice milk, resulting in a COD (chemical oxygen demand) up to 53000 mg / L, accordingly waste of crops and environmental pollution are caused. Therefore, the invention relates to an energy-saving and water-saving yellow wine production device integrating rice soaking, rice steaming and fermentation. The energy-saving and water-saving yellow wine production device is characterized in that 1) rice soaking is performed in a cycling spraying manner, which, compared with traditional flooding type rice soaking manners, can save water by more than 1 / 2, and meanwhile, rice milk can be completely utilized to achieve zero discharge; 2) rice soaking period is shortened to 1-2 hours, so that losses of raw material rice during rice soaking can be significantly reduced; 3) rice soaking, rice steaming and fermentation are performed in situ through one device, so that material conveying strength can be significantly reduced, energy sources, labor, facilities and rice soaking and washing water can be saved, and meanwhile production lands can also be saved.

Description

technical field [0001] The invention belongs to the technical field of food processing, especially the technical field of brewing. Background technique [0002] Shaoxing rice wine has a long history, and written records can be traced back to the Spring and Autumn Period and the Warring States Period. After thousands of years of evolution and development, it has formed a unique style of brewing with Jianhu water, which is a treasure of Chinese national culture. In recent years, the rice wine industry has developed rapidly and maintained an annual growth rate of about 10%. However, the problem of environmental pollution has become more and more serious. Traditional winemaking technology needs to burn a large amount of coal to obtain winemaking steam, which is a high-energy-consuming industry. The rice milk produced by soaking rice The water COD is as high as 53000mg / L, which greatly increases the production cost and the difficulty of environmental governance, which will inevi...

Problems solved by technology

In recent years, the rice wine industry has developed rapidly and maintained an annual growth rate of about 10%. However, the problem of environmental pollution has become more and more serious. Traditional winemaking technology needs to burn a large amount of coal to obtain winemaking steam, which is a high-energy-consuming industry. The rice milk produced by soaking rice The water COD is as high as 53000mg / L, which greatly increases the production cost and the difficulty of environmental governance, which will inevitably affect the further development of the rice wine industry in the future, and is one of the long-standing technical bottlenecks in the development of the rice wine industry
