Description
Technical field
The present invention relates to liquor production technical field more particularly to a kind of methods for measuring alcoholic strength and real-time single bottle capacity
And measuring system.
Background technique
White wine manufacturing enterprise needs in each process procedure such as distillation, storage, hook tune, filling in real time in process of production
Measure the alcoholic strength content of white wine.Present measurement method is: being existed using alcohol meter and thermometer measure and the tested wine sample of record
Alcohol meter indicating value and temperature value under Current Temperatures are tested the mark of wine sample when then obtaining 20 DEG C by inquiring " alcohol conversion table "
Quasi- wine angle value.In actual operation, when encountering the multiple and different wine samples of continuous multiple batches of big measurement, different ranges need to frequently be replaced
The alcohol meter of range is simultaneously carried out continuously observation, reading and record and constantly retrieval alcohol conversion table, can make the work of operator
Amount is significantly increased, and working efficiency is relatively low, and is easy to artificial mistake occur, and operate alcohol meter need to have it is certain
Professional knowledge, such as: need to be read by the meniscus lower edge that alcohol meter is contacted with liquid level, should estimate when reading alcohol meter indicating value and read indexing
/ 10th of value, alcohol meter floats up and down in wine sample must not exceed three scale division values, and alcohol meter must not be with when immersing wine sample
Container surrounding, bottom and thermometer collide, and can not skillfully grasp its operation without the personnel of long-term professional training and want
Neck, so that measurement result generates large error.In addition, when finished product liquor filling, to guarantee that factory product meets national phase

Row accurate measurement.Currently used method is: firstly, service precision relatively high " volumetric flask " carries out school to dosing filling machine
Quasi- (because the bottleneck of volumetric flask is elongated, reducing liquid level, to can get higher precision).Specific practice is: starting bottle placer is filling
One group of sample simultaneously records corresponding filling head number one by one, the volume of each sample is measured respectively using volumetric flask, according to inclined
Residual quantity adjusts the filling amount of corresponding filling head one by one.Above step is repeated several times, until confirmation filling amount stably reaching standard can
Start to produce in batches.Because the alcoholic solution for the single phase homogeneous that white wine is made of the alcohol and pure water that can mutually mix, close
Spend characteristic and be different from pure water, be influenced by temperature it is larger, such as: (note, %vol refer to that alcohol is molten for the white wine of 50%vol (at 20 DEG C)
" concentration of volume percent " of liquid, that is, daily " the wine degree " being commonly called as) density at 0 DEG C is 957.026 ㎏/m3, and 40
DEG C when density be 899.270 ㎏/m3, the volume differences of 500ml (at 20 DEG C) have reached 31.21ml.This is because environment temperature
Variation cause the density of wine liquid to be changed, so as to cause the change of volume, therefore in production link, inspection on duty
Member need at any time be sampled finished wine, inspect its alcoholic strength by random samples at random and whether net content is overproof, find the problem, need to be at once to filling
Installation filling amount is adjusted；Also even more important is a little that existing national regulation is complete to the regulation of alcoholic strength and net content
Portion refers to the measured value at normal temperature, i.e., 20 DEG C.Alcoholic strength has passed through inquiry " alcohol conversion table " and has been made that effectively
Compensation, and the compensation method to " net content ", national correlation department does not put into effect any relevant standards and specifications at present, respectively

1. a whole bottle wine sample to be measured is all added in measuring bottle, liquid level should be located exactly between high-low limit graticule.
(note: because the volume of measuring bottle be it is specific, a kind of volumetric flask of model can only measure the solution in same volume range.So
Before measurement, should correctly select the volumetric flask to match with surveyed single bottle capacity) after liquid fluctuating stops, according to it is aforementioned measure to
It surveys the step of alcoholic solution standard wine is spent and measures its density value ρ；
2. the pressure values P measured according to lower pressure sensor1, data processing module can calculate down according to formula (1-1)
Sensor to liquid level height value h1；
3. data processing module is further according to hDifference=h1-hMark, calculate VDifference, then VDifference=hDifference×SMark；

" net quality " and " net volume " being converted under Current Temperatures, include the following steps:
According to the standard wine degree for the wine sample to be measured that step 1-6 the method measures, data base querying " international alcohol is utilized again
Table ", obtain density p of the wine sample to be measured under normal temperature20；
According to factory " net content " V that must reach under normal temperatureOnly, calculate the net quality m of standard under normal temperatureOnly, i.e. mOnly=
ρ20VOnly；Because quality does not vary with temperature, so the net quality under Current Temperatures is equal to the net quality under normal temperature；
The real-time quality under Current Temperatures, i.e. m are calculated according to real-time volume measured by step 1-8 and real-time densityt=ρtVt,
Calculate the difference DELTA m, i.e. Δ m=m of real-time quality and net qualityt-mOnly, and shown output；
According to " net quality " mOnlyWith " real-time density " ρ under Current Temperaturest, calculate " standard net content " V under normal temperatureOnlyFolding
Calculate " conversion net content " V under Current TemperaturesFolding, then VFolding=mOnly/ρt；
It calculates real-time volume and converts the difference DELTA V, i.e. Δ V=V of net contentt-VFolding, and export；
The standard net content that must reach under obtained Δ m and Δ V, real-time single bottle content as under Current Temperatures and normal temperature
Deviation, for examining and adjusting the filling amount of filling head.
4. a kind of alcoholic strength and net content measuring system, which is characterized in that including Mersure Controler, volumetric flask, upper pressure sensing
Device, lower pressure sensor and temperature sensor, the volumetric flask include bottle body and bottleneck, indicate graduation mark in the middle part of the bottleneck,
The graduation mark includes 0 bit line of standard, limes superiors graticule and limit inferior graticule, the upper pressure sensor, lower pressure sensor
And temperature sensor is placed in volumetric flask body, the Mersure Controler includes data processing module, display module, two pressures
Force snesor interface, temperature sensor interface and display screen, described two pressure sensor interfaces respectively with upper pressure sensor,
Lower pressure sensor and data processing module electrical connection, the temperature sensor interface respectively with temperature sensor and data processing
Module electrical connection, the display module are electrically connected with data processing module and display screen respectively.
5. a kind of alcoholic strength according to claim 4 and net content measuring system, which is characterized in that the bottle body bottom of volumetric flask
Portion is plane, and body is spherical shape, and bottleneck is elongated cylinder.
6. a kind of alcoholic strength according to claim 5 and net content measuring system, which is characterized in that at the top of volumetric flask bottleneck
Integrally formed with funnel.
