Famous Japanese brewery pull visa technology applied to traditional liquor production techniques

In Japan in 1934, the "father" of whisky bamboo crane zheng filial piety in Japan over the northern city of city created a whisky co., LTD.He chose more than city, because the climate here similar to Scotland's climate, and it was there to learn whisky making himself."Yu city" was chosen as the brand name of now, the city is famous for its popular abroad as a representative of the Japanese whiskey.

A nail in the south of Japan whisky moji breweries can be traced back to 100 years ago, its predecessor was founded in 1914 "suzuki store dairy products factory".Moji in Meiji era, as Japan's export ports designated by the government and booming.Existing style of red brick factory adopt western-style design, are just the proof of its cutting-edge technology at that time.In 2006 after many mergers and acquisitions, become a part of a whisky, is asahi group holdings co., LTD in the production of Japanese traditional distillation drink soju main breweries.In recent years, the factory not only produce shochu, also produce whiskey and other spirits.As a whisky mixed breweries, also produce high quality base liquor.

Soft continous liquor taste: from shochu technology and exquisite art of master handed down from generation to generation

A a whisky brewed moji factory production of a variety of authentic barley liquor.Shochu has two types: b shochu and class a shochu.B shochu general distillation only once, and keep a unique taste of raw materials.The class a shochu repeatedly distillation, is famous for its pure taste.Both distillation method originally used in the production of whiskey.

A a whisky brewed moji factory main products is a class b mixed liquors.This wine a mix class a and b class liquor liquor, taste is more gentle, more suitable for collocation all sorts of meals.However, this requires careful mixture of several different types of unprocessed shochu, rely on the management of the manufacturing process is very detailed.

A a whisky moji breweries takahashi, woven said: "we mixed liquor fragrance come mainly from yeast to produce ester (aromatic substances).""Every step from production could to distillation, we must be careful, very focused.Especially according to the control fermentation temperature, fermentation conditions constantly create a good environment for yeast fermentation.

, says Mr Takahashi shochu process involves the use of active ingredients, such as could and could and yeast mixture.Because of this, even the large-scale automated production, many steps still rely on skilled shochu brewmaster skills and senses.In addition, to be able to according to the daily temperature, humidity and other external environmental factors of fluctuations, precise control of starter-making conditions and water content, knowledge accumulation and feedback is very important.Has Japanese liquor industry automation technology is still in the tirelessly pursue spirit.

Alcohol concentration is measured with a continuous online instead of manual sampling

Visa, refractometer can be used to detect the alcohol after vacuum distillation concentration (intensity).Through the install the refractometer in distillation stills export, on-line concentration measurement can be performed.

In view of the taste of wine at the early, middle and late completely different, so precise control in the process of brewing distillation end time is very important, must grasp the taste of the corresponding moment required.Too late to stop the distillation will greatly influence the liquor quality.But soon stopped distillation can also lead to alcohol production.

Before the introduction of alcohol concentration online refractive index measurement, requires a few times before each batch distillation was done lab sampling analysis.Therefore, when approaching at the end of the distillation operation, must be left in the scene, head of the work.It is the key to the distillation process node, improper handling can cause the failure of the distillation, so before January of koji making, yeast mash fermentation and secondary fermentation will be wasted.Sampling survey conducted by different personnel will directly affect the quality of wine and alcohol concentration.Obviously, the precise digital control and continuous monitoring to ensure consistent quality.However, this requires a high precision instrument that can measure a variety of shochu virgin pulp.

Understand the visa refractometer

In 2020, the draw according to visa visa refractometer measurement results, a a whisky moji breweries alcohol concentration of several products chemical curve modeling Settings.Alcohol concentration using refractometer measures for when a whisky moji breweries is a kind of new method, so they are slightly hesitant.

"Refractometer was recommended for the first time, I really feel there is no correlation between refractive index and the alcohol concentration, using refractometer to test almost impossible."Mr Takahashi said."It is said that 99% of the ingredients are water and ethanol in the shochu.The wine quality is decided by the balmy composition of the remaining 1%.I think this tiny difference of 1% will have great influence on the refractive index, and so does not test the linear refractive index.

One of the sampling test and visa refractometer measurement data show that both have obvious correlation, so we decided on a a process pipeline installation refractometer to test.A month said the test results of refractive index and the alcohol concentration has the stable correlation, this make sure Mr Takahashi, visa, in situ online refractometer can be installed in the operation of their craft.

Moreover verified, visa refractometer prism self-cleaning function can effectively eliminate prism using life cycle precision by a worrying problem."If the cleaning function to ensure, we will consider introducing CIP cleaning," Mr Takahashi says."But it also found that there is no need to reduce the investment cost, that's why we decided to pull visa refractometer in the process of integration to our another main reason."

Online refractometer in liquor production in the process of in situ measurement

• To improve the sampling efficiency, speed up the automation
  From laboratory sampling analysis to on-line measurement for quality and cost of the benefits."The first step is to improve the efficiency of the sampling work," said Mr Takahashi."Before sampling, the head must be finished in the distillation about 20 minutes to the scene.Every distillation two batches, which leads to the sampling takes 40 minutes a day (twice a day, every time 20 minutes).At present, we are according to the visa refractometer measurement results to control the drawing process, by the end of the automatic control of distillation operation, realized almost completely automated distillation process."
• To improve the quality of each batch consistency
  In the aspect of quality control, through the refractometer clear standard measurements to reduce the previous completed by workers to determine the distillation time lead to the quality of the differences.This helps to improve the consistency of product quality, and support the use of the data validation and analysis of quality.
• The application of customized solutions
  "We had a good out of visa application support, tailor the measuring solution for our process, we plan used in other product lines in situ online refractometer, such as new shochu virgin pulp and distillation process pipeline."Mr Takahashi says.
• Free maintenance
  Changing volume, as a result of alcohol in the distillation process will produce many bubbles, and often appear fluid flow fluctuation, such an environment may be linear measurement error.A a whisky moji breweries once use density value of the mass flowmeter, but due to flow from distiller liquid flow fluctuation and the influence of the bubble, the conversion of alcohol density is not stable.The experience that they always think bubble and flow fluctuation will make online measurement is difficult to implement.

"Visa refractometer is not affected by the bubbles, and measured value is stable," Mr Takahashi commented.

"The stability of a measured value can be very useful in the distillation control."Since the use of visa pull refractometer for two years, equipment running smoothly, without any common faults, emergent problems or drift."Every day we analysis the distillation concentration trend, to ensure that the correct distillation was detected in time," Mr Takahashi says."The whole process of measurement equipment is stable.Another advantage is that because there are no big faults in the operation process, so there is no running costs."

From the Angle of the refractive index

"I think the refractive index to measure accurately how shochu varieties and the correlation between the alcohol strength," said Mr Takahashi."As long as there is correlation between refractive index and the material under test, refractometer can be used in a variety of applications, which left a very deep impression on me."

To achieve continuous daily improvement, visa will continue to listen to customer feedback, carefully calibrated for the product parameters setting and display Settings, make it ready for further enlarged our product lines.In the future, food and beverage sector is expected to realize automation, to optimize the cost efficiency and improve the health standards.

A a perfect fusion of the winemaker's skills and experience, over a long time ago in the city and moji opens up a new culture.A century later, in a visa measurement technology, under the help of new technology for the armour to create brilliant.We hope the visa pull measurement technology for from infrastructure to everyday life and culture and so on a wide range of improvements continue to provide support.
