Technical Field

[0001] The utility model relates to a stirring structure, in particular to a stirring structure of a barley malt juice saccharification reaction kettle, and belongs to the technical field of barley malt juice processing. Background Art

[0002] Barley malt juice is a beverage extracted from high-quality barley malt through multiple processes such as screening, cleaning, saccharification, and gelatinization. It is also called "malt extract". At the same time, it must also undergo hydrolysis and enzymolysis to fully break the protein macromolecules contained in the high-quality malt into small molecular polypeptides and some free amino acid molecules, which is more conducive to the absorption and utilization of microorganisms. When making it, a reactor is usually used to stir the barley malt juice to produce a saccharification reaction, and then carry out subsequent processing operations.

The required material cost is relatively high, which reduces the practicality of the device; 2. After using it for a period of time, when the stirring blades need to be replaced, the entire structure needs to be disassembled for replacement, which is troublesome to operate and the use effect is not very good.
