Description
Technical field
The present invention relates to measure the method that aromatic Chinese spirit goes out the poor unstrained spirits alcoholic strength in cellar for storing things, belong to the detection technique field.
Background technology
China white wine has developing history in several thousand, and it has long traditional history as the peculiar wine kind of China, in world's strong drink series products, takes the course of its own, and is one of six big Spirits in the world.To reform and opening-up, China's liquor has obtained the development of advancing by leaps and bounds, and the scale of each big famous-brand and high-quality brewery is constantly developed, and production capacity constantly increases, and occupies the aromatic Chinese spirit of the market share 70% more than, and its scale continues to expand especially.In the Production of Luzhou-flavor Liquor process; For understanding each fermented grains in pits starch utilization ratio and alcoholic fermentation situation; Need do the mensuration of alcoholic strength to the poor unstrained spirits in cellar for storing things (having fermented finishes, and waits for that the poor unstrained spirits of batching, steaming wine is called the poor unstrained spirits in cellar for storing things) that goes out of each Jiao Chi, thereby better instruct lower whorl to produce.
The assay method that present aromatic Chinese spirit goes out the poor unstrained spirits alcoholic strength in cellar for storing things is: get the poor unstrained spirits of 100.0g and add water 250ml, distill out 95ml, add water and mend to 100ml; Distillate adopts the glass alcohol meter to measure its wine degree; Its distillation time is long, and each sample distillation time is more than 30min, and power consumption is big; And account for the experiment place, poor unstrained spirits appearance especially to be measured more for a long time.And measure poor unstrained spirits appearance limited amount each time, strengthened experiment labour intensity virtually, and the error at measurment of the poor actual alcoholic strength of unstrained spirits or fail mensuration in time all can be brought certain influence to production.
Summary of the invention
Technical matters to be solved by this invention provides the method that a kind of fast measuring aromatic Chinese spirit goes out the poor unstrained spirits alcoholic strength in cellar for storing things.
The present invention measures the method that aromatic Chinese spirit goes out the poor unstrained spirits alcoholic strength in cellar for storing things and comprises the steps:
A, the poor unstrained spirits in the cellar for storing things that is soaked in water out filter then, and the mensuration filtrate density is ρ;
B, when filtrate density ρ≤1.000g/ml, calculate the alcoholic strength Y of the poor unstrained spirits in cellar for storing things, Y=-794.417 ρ+792.515 with following formula; Wherein the unit of filtrate density ρ is g/ml;
When filtrate density ρ＞1.000g/ml, calculate the alcoholic strength Y of the poor unstrained spirits in cellar for storing things, Y=-3458.729 ρ+3475.178 with following formula;
Wherein, the unit of above-mentioned filtrate density ρ is g/ml, and when Y≤0, the alcoholic strength that goes out the poor unstrained spirits in cellar for storing things is 0.
Wherein, In order to make the mensuration result more accurate; Above-mentioned a step preferably adopts out the water logging bubble (most preferably adopting out the water logging bubble of 3 times of the poor unstrained spirits quality in cellar for storing things) of 2～4 times of the poor unstrained spirits quality in cellar for storing things, goes out time that the poor unstrained spirits in cellar for storing things is soaked in water to be preferably 8～12min (go out the time optimal that the poor unstrained spirits in cellar for storing things is soaked in water and elect 10min as).
Wherein, above-mentioned a step measurements filtrate density can adopt conventional method or equipment, as: adopt densitometer or gravimetry instrument to measure filtrate density.
The inventive method mensuration aromatic Chinese spirit goes out the poor unstrained spirits alcoholic strength in cellar for storing things and has following advantage: speed is fast, and efficient is high, and the result is (error is no more than 5%) comparatively accurately, and energy consumption is low, and method of operating is simple.The present invention has broad application prospects for the mensuration that aromatic Chinese spirit goes out the poor unstrained spirits alcoholic strength in cellar for storing things provides a kind of new approach.
Embodiment
