Description
Technical field
The utility model relates to a kind of device of stable wine quality, particularly a kind of device of removing dissolved oxygen in the wine.
Background technology
Wine is divided into two big types on ME: brewing wine and liquor.
Brewing wine: fermenting raw materials → squeeze and filter → storage is aging → blend filtration → finished product can, the typical case represents Chinese rice wine, japanese sake, wine etc.
Liquor: fermenting raw materials → female wine with dregs distillation → storage is aging → blend filtration → finished product can, the typical case represents China white wine, vodka, brandy, whisky or the like.
General wine is being brewageed that magma after squeezing or distillation are accomplished in fermentation will experience 1～3 year even the storage of ten several years or longer time, is being stored sth. in a cellar.Different wine has different storage containers, for example oak barrel, Mare Nectairs, pithos, aluminium pot, stainless cylinder of steel or the like, and wherein oak barrel, Mare Nectairs ceramic cylinder are preferable.Because it is exactly that wall of container has microvoid structure and can communicate with outside air that this second category vessel has common characteristics, the aldehyde in the wine, alcohol, acid, ester etc. need the participation of oxygen in the air to carry out reactions such as oxidative esterification, hydrolysis, condensation.Help the ageing, aging of wine.
In the process of storage, container itself can dissolve in the content of timber and the metals ion of metallic substance, and wine liquid is easy to carry out alcohol in this type container, water associates.Be the glue nuclear at center with the metals ion and then form stable colloidal solution.Wine needs esterification and oxidizing reaction that certain oxygen participates in wine to promote the aging of wine in storage period.
Through storage, ageing, sophisticated wine is called former wine, also is not finished wine.Before coming into the market, wine also has most important operation of a step blending.It is that differently flavoured old wine, foreshot, wine tail, spices, water etc. are allocated combination, to reach best taste flavor.This process will be employed wine pump, pneumatic stirring, and therefore, part oxygen gets into again and forms dissolved oxygen in the wine, and the existence of " oxygen " is exactly the factors of instability of wine, and the wine of blending changed obviously in three to seven days, and it is coarse that mouthfeel becomes, the wine body hole.Therefore it is extremely important to take off " oxygen ".Deoxidation is to guarantee the stable important measures of finished wine quality mouthfeel.
Existing is the Changing Pattern of example explanation dissolved oxygen in white spirit mixing with the China white wine.
In the white spirit mixing process,, dissolve in oxygen virtually because the adjustment of wine degree and adding of liquor skeleton composition need pressurized air to stir.Because oxygen is active, make troubles for the blending of finished wine in later stage.So stablize the quality of wine, it is extremely important that the removal of dissolved oxygen just becomes.Here it is why white spirit can become very coarse blending three to the seven days mouthfeels in back, the wine body hole, this and dissolved oxygen have a substantial connection.See also Fig. 3 and Fig. 4; Variation and dissolved oxygen content that two figure show Luzhou-flavor 38 degree finished product liquor four big esters respectively change; The variation that can find out low finished wine is very consistent with the decline relation of dissolved oxygen, because the existence of finished wine dissolved oxygen, so the hydrolysis of ester is very active in first three middle of the month; Because the consumption of dissolved oxygen becomes slowly, finished wine gets into stationary phase after three months.This variation that also may be interpreted as 1 year lactone of low finished product bottled wine mainly appears at first three months, and total ester range of decrease can reach 20%, tends towards stability later on.Through deoxidation treatment, and it is very stable to seal bottled wine, gets into air in case open bottle cap, reseals a week, can obviously change original style, water taste and wine tail tart flavour occur.When dissolved oxygen depletion in the wine totally the time, the wine body becomes relatively stable, and the oxygen that uncork for the second time gets into dissolves in chemical equilibrium and the colloid equilibrium of having broken the wine body again, and the wine body has produced new variation again, and new variation has also taken place quality.So deoxidation is very important before the bottled wine can.
In sum, the existence of dissolved oxygen in ripe wine can bring a series of negative interactions.As the ester class of quickening in the wine decomposes the colloid equilibrium break wine liquid, and the local flavor of wine and physical and chemical index are changed.Therefore, former wine blend preceding and/or the bottled wine can before need deoxidation.The removal of oxygen is divided into physics and chemical process, and heat de-airing, vacuum outgas belong to physical method.Physical method drops into height, energy consumption is big, and residual oxygen is high.
