[0002] Cellar sealing is an important step in the process of Baijiu brewing. Its main purpose is to isolate the fermented grains from the external air, create anaerobic conditions, prevent the intrusion of harmful microorganisms, and at the same time avoid the excessive consumption of fermentable sugars by yeast when there is sufficient air, so as to ensure the normal progress of liquor fermentation. The traditional cellar sealing method uses special clay or plastic sheeting to smear (press) on the fermented materials on the cellar surface to seal the cellar surface. The problems in the specific use process are as follows:

[0003] (1) After the piled grains are put into the cellar, the cellar surface needs to be manually sorted into a steamed - bun shape and manually patted tightly to ensure a certain thickness. For large - scale wineries, a large amount of human resources are required, and the labor intensity is high.

[0004] (2) After cellar sealing, it is necessary to check daily and moisten the cellar surface to prevent the sealing cellar mud from cracking, and there are many repetitive tasks.
