Description

Technical Field

[0001] This utility model relates to the technical field of baijiu brewing equipment, specifically a cellar mud adhesion device for brewing strong-aroma baijiu. Background Technology

[0002] Baijiu, one of the world's six famous distilled spirits, has a long history of brewing. Based on differences in brewing koji, fermentation containers, raw materials and mash preparation processes, and natural environment, baijiu can be divided into 12 aroma types. Among them, strong-aroma baijiu has the largest production volume and the highest market share. Cellar mud is the clay adhering to the bottom and inner wall of the cellar. Cellar mud is an important source of ethyl hexanoate, a characteristic flavor compound of strong-aroma baijiu. In the brewing process of strong-aroma baijiu, cellar mud is an important place for the generation of flavor compounds in the liquor, and plays a decisive role in the flavor characteristics and quality of strong-aroma baijiu. Cellar mud is rich in microorganisms such as hexanoic acid bacteria and lactic acid bacteria and their groups. The various enzymes produced by their metabolism participate in various reactions of fermentation and produce a variety of flavor compounds, including acids, esters, ketones and alcohols. These flavor compounds contribute to the unique aroma, flavor and rich taste of strong-aroma baijiu.

[0003] Under specific conditions and within an appropriate range, the larger the contact area between the mash and the cellar mud, the more significant the influence of the cellar mud on the microorganisms and flavor metabolism of the mash. This results in the generation and accumulation of aroma substances such as ethyl hexanoate in the mash, leading to better quality strong-aroma baijiu. However, the mash in the upper layer of the cellar does not contact the cellar mud at the bottom, resulting in lower content of flavor substances such as ethyl hexanoate in the resulting baijiu. Therefore, increasing the ethyl hexanoate content in the baijiu produced from the upper layer of the cellar is an important issue that needs to be addressed in the adjustment of the strong-aroma baijiu brewing process. The "mud-blended fermentation" process, which increases the contact area between the fermented mash and the cellar mud, can be considered an important and preferred approach. In addition, the cellar needs to be replaced or maintained in a timely manner after different production runs, and the degraded cellar mud also needs to be replenished with nutrients and maintained in a timely manner to maintain the microbial community and vitality of the cellar mud. To this end, we propose a cellar mud attachment device for strong-aroma baijiu brewing. Utility Model Content
