In the past few months, liquor has been a hot topic in society, and the ups and downs of Moutai and Wuliangye stocks have touched the hearts of countless people. But in fact, from ancient times to the present, wine culture has always attracted people's attention and occupies an important position in Chinese history.
Poet immortal Li Bai Youyun: Life must be happy, don't make the gold bottle empty to the moon. Drinking alcohol was an excellent way for the ancients to express their ambitions and emotions.
Different flavor types of liquor have their own flavors: the sauce flavor type is elegant and delicate, and the entrance is soft and mellow; The aroma of the strong aroma cellar is rich, and the entrance is sweet and refreshing; The fragrance type is mellow and mellow, and the entrance is sweet and refreshing, which greatly increases the fun of people's wine tasting.
Modern liquor brands also have their own characteristics, such as Gujing Gongjiu, which is known as the "peony in wine", which is "clear as crystal, pure as orchid, luscious and mellow in the mouth, and long-lasting aftertaste", which is deeply loved by the majority of liquor lovers. At present, Gujing Gongjiu is building a new intelligent park in response to the country's call for the intelligent development of the liquor industry.
In the production process of liquor, alcohol concentration is one of the most important process indicators, and the measurement of alcohol concentration is involved in the process of slipping, blending and the identification of the final finished liquor.
Traditionally, alcohol measurement is done by taking a sample and then using a buoyancy concentration meter. This is not only cumbersome and inefficient, but also has human error, resulting in the inability to obtain real-time and accurate alcohol concentration values, hindering the goal of large-scale wineries to achieve automated transformation, control production, and improve efficiency.
How to make the traditional alcohol concentration measurement also automatic and intelligent? HOMKOM's HK-CMF series Coriolis mass flow meters provide high-precision mass flow measurement, and can also perform high-precision concentration measurement at the same time.
Distilleries are usually equipped with mass flow measurement points, and the HK-CMF mass flow meter is used at the measurement point to measure the flow rate and concentration at the same time, which is a multi-purpose meter, which perfectly meets the needs of customers who want to know the real-time concentration value.
Since 2018, HK-CMF has carried out in-depth cooperation with Gujing Gongjiu for the measurement of ** alcohol concentration, and has achieved ideal measurement results (in line with internal control standards), which has won the confidence and recognition of Gujing Gongjiu in this application.
The principle of measuring alcohol concentration by a mass flow meter
The Coriolis mass flow meter can measure the flow, density and temperature at the same time: the density, alcohol concentration and temperature of the liquor have a fixed correspondence, so the Coriolis mass flow meter can obtain the concentration of alcohol by measuring the density and temperature of the liquor.
The HK-CMF series mass flow meter has a built-in international standard alcohol concentration data sheet, which can convert density and temperature into concentration (ABV) for display and output. The higher the density and temperature measurement accuracy of the flow meter, the higher the accuracy of the converted alcohol concentration.
When it comes to alcohol concentration measurement, the HK-CMF mass flow rate offers the following advantages:
Industry-leading density measurement accuracy
Density accuracy is crucial in concentration measurement, and its advantages and disadvantages basically determine the concentration accuracy. The HK-CMF series of mass flow meters can provide a variety of different density accuracy classes and measurement ranges according to customer needs.
The density accuracy is 0At 5kg m3, it can theoretically reach 0Accuracy of alcohol concentration measurement within 5°; The density accuracy is 0At 2kg m3, it can theoretically reach 0Accuracy of alcohol concentration measurement up to 2°. （±0.5kg m3 and 02kg m3 is the industry's leading mass flow meter density measurement accuracy).
It is worth mentioning that the nominal density accuracy of the mass flow meters of common brands on the market is generally the highest accuracy, which can only be achieved at a certain temperature and pressure (e.g. 20, one atmosphere). In practice, process temperatures and pressures tend to deviate from this specific temperature and pressure, thus introducing additional density errors.
The HK-CMF mass flow meter will only introduce 0. whenever there is a temperature deviation of 1The density error of 05kg m3 is leading in the industry with such a low density error. In addition, the Promass Q-series mass flow meters are guaranteed to be 0 in a common temperature range of 20 to 60The density accuracy of 2kg m3 is extremely rare in mass flow meters.
Industry-leading temperature measurement accuracy
In addition to the accuracy of density measurement, temperature accuracy also has a certain influence on concentration accuracy. The temperature measurement accuracy of the HK-CMF series mass flow meter is also in the leading position in the industry. The mercury thermometer used in the traditional buoyancy measurement method can only be accurate to 1, and the temperature accuracy is low, and 0Concentration error of about 2°.
The temperature accuracy of Promass F is 05℃ ±0.5% *t ℃。The Promass Q uses the industry's highest accuracy temperature sensor, which is even more than 01 °c ± 0.3% *t °C, which almost does not introduce additional concentration errors due to temperature measurement, and minimizes the influence of temperature errors on concentration measurement.
Note: t is the actual measured temperature value.
Adjust the parameters according to the actual application to improve the accuracy of concentration measurement
In some measurement points, the temperature range and concentration range of baijiu are often fixed, for example, between 15 and 30, 50 and 53° baijiu are measured.
Enter this temperature range and concentration range into the debugging software FieldCare or Devicecare, and the software will automatically generate a formula that is more suitable for this temperature and concentration range, so that the flow meter can achieve higher concentration accuracy in this range.
A wide range of solution concentrations can be measured
In addition to the alcohol data sheet, the HK-CMF mass flow meter also has a built-in standard data sheet for more than 20 common solutions, allowing users to directly measure the concentration of these solutions without any special settings.
The built-in solution contains: ethanol, methanol, fructose, glucose, invert sugar, sucrose, wort, high fructose corn syrup (HFCS42), high fructose corn syrup (HFCS55), high fructose corn syrup (HFCS90), ammonia, ammonium hydroxide, ammonium nitrate, ferric chloride, potassium hydroxide, sodium chloride, sodium hydroxide, phosphoric acid, nitric acid, hydrochloric acid, sulfuric acid, hydrogen peroxide.
Customized services are available for special solutions
If you want to measure the concentration of other solutions, you only need to provide data on temperature, concentration, and density. Based on the data, FieldCare or DeviceCare calculates a concentration formula that is specifically adapted to the solution.
As more and more well-known wineries in China gradually enter the era of automation, the demand for concentration measurement has also increased greatly. So far, many well-known distilleries and pharmaceutical factories in China have chosen to apply HK-CMF series mass flow meters to the measurement of alcohol concentration.
