First, caused by the storage container. Liquor is stored in an iron container. Due to prolonged soaking, part of the protective layer of the iron container made of pig's blood is peeled off, and the iron is exposed on the outside. The iron ion dissolves in the wine and reacts easily with the acid in the wine to form iron salts. . At the same time, divalent iron ions are oxidized by oxygen in the air and precipitates of trivalent iron compounds are formed, causing excessive liquor solids.
Second, caused by the bottle of health and filter aids, packaging process, the new bottle often retain a lot of silicates. After the bottle is washed, the water in the bottle is not clean or the new bottle is not washed. Only flush with clean water, easy to make the silicate inside the bottle into the wine. After the silica is reduced, it is porous and has a large specific surface area. Strong adsorption. If the quality of water used for washing bottles is not acceptable, generally the bottle does not control the internal water, and at least 2 ml of water remains in the bottle, which is also one of the reasons for excessive solids. When liquor is filtered through a diatomaceous earth filter, the filter effect will be affected due to different batches or origins of the diatomite filter aid, or due to improper use, filter cloth leakage, filter disc loose, etc., can also cause solids Excessive standards.
Third, the short storage time caused. Liquor storage period has a certain time limit, the liquor storage period is divided into blended products before storage and blending finished products after storage. Especially in the high season, due to tight schedules and heavy tasks, sometimes the storage requirements cannot be met. Generally blended finished wines require more than 7 days storage period, some time is short, only 4-5 days on the packaging, which results in the association between the wine and the redox reaction between the molecules is not enough, so that the wine in the free substance binding Less, some of the precipitates have not yet completely settled, and after a certain period of time, the bottles have precipitated after bottling, causing excessive solids content.
