Description

Technical Field

[0001] The utility model relates to the technical field of special machinery for wine production, and in particular to an air chamber cleaning device for an air drying machine and an air drying machine. Background Art

[0002] Different types of liquor have different brewing processes. Luzhou-flavor liquor generally adopts continuous slag brewing, mixed steaming and mixed burning, and continuous slag in old cellars are its typical characteristics. The production of sauce liquor adopts the process characteristics of saccharification accumulation and pool fermentation. But no matter what type of liquor, the raw grains need to be crushed, steamed, spread and dried to mix with koji before entering the saccharification and fermentation process. The saccharification process requires the participation of relevant enzymes. The amylase involved in the saccharification process belongs to the hydrolase, which catalyzes the hydrolysis reaction. Amylase is a general term for enzymes that hydrolyze starch. It can continuously shorten the long chain of starch until it is hydrolyzed into glucose. The amylase in the fermented grains mainly comes from Daqu. Daqu is a complex enzyme preparation that contains protease, pectinase, lipase, etc. in addition to amylase. Therefore, the use of Daqu and the way of using koji in the brewing process have a far-reaching impact on brewing production. Before each koji is added, the fermented grains must be spread and dried to the optimal temperature for koji to ensure the normal recovery of Daqu microorganisms.

[0003] In the traditional brewing process, the mash is spread out to dry on the site or on a drying bed, which is inefficient, slow, and requires a lot of labor. With the development of mechanization, a mash spreading and adding koji machine for brewing has been gradually developed. The mash passes through the wind chamber along a chain plate with holes to cool down, and then passes through the water replenishment device at the rear end of the spreading machine, and the koji adding device completes the entire mash spreading and drying operation. During the cooling process of the mash in the wind chamber, part of the mash will fall into the wind chamber through the holes in the chain plate. The wind chamber needs to be cleaned manually after each spreading and drying. If it is to be cleaned, a large amount of water is needed to flush it, which will damage the wind chamber fan and reduce the service life of the fan. If it is not cleaned, the deposited mash will become moldy and infested with insects, causing food safety accidents. Utility Model Content
