National Beer

Chapter 692 Chromatic Acidity and Total Nitrogen

"I have learned a few kinds of brewing beer."

Qin Dong is only waving to let Zhongxing, then ignore Zhao Shilin, sitting in the sofa.

The Germans have not taken him down and sit down, and even the number of gifts, Zhao Shilin has been disgusted in this translation.

"You are like dried beer, this kind of beer is high, low residue, high carbon dioxide content, characteristics of dry taste, strong killing force ..."

"Ice beer, cool the beer to the freezing point, so that the beer has a small ice crystal," Qin Dong used to be used, "and then filtered, the ice crystal filtrates after the beer ..."

"Wheat beer, wheat is the main raw material, beer made by the above fermentation method or the following fermentation method ... Low alcohol beer, less alcohol content than 2.5%, alcohol content less than 0.5% is a guano beer ... Green beer, Add natural spirulina extracts in beer, rich in amino acids and trace elements, beer green ... "

Oh, there is so much beer in a mouth, this translation is aware of the beer industry, and Zhao Shilin's face is eased.

"And white beer, white beer uses two different yeasts for secondary fermentation in the production process, and other flavor substances, such as ester, and its final finished product during the second fermentation process. Wine has not been filtered, and the finished wine contains a lot of protein and yeast, so from the appearance, the finished wine is very turbid, showing a white emulsion ... "

"This season," Qin Dong looked at the snow on the air-conditioned air-conditioning hang up, "it is best to drink a little warm beer ..."

The last kind of beer, Zhao Shilin really did not hear, this era did not have a warm beer.

"It is after the fermentation of ginger or , there is a role in preventing colds and gastric cold ..." Qin Dong laughed.

Oh, look at the audience, the audience is not the center, Zhao Shilin just nowhere, "OK, you may be seen from the foreign book, but you seem to be used as a translation. It is also qualified. "He added another sentence," You know beer. "

Zhongxing is laughing, can he not understand beer? He is the close-up disciple of Mei, is his masterpiece, but he can't introduce Qin Dong. He is the general manager of the beer, now there is This is a bullish.

Moreover, the joint venture of Shijie Beer is originally dark, Chen Cang, Li Dai Tao.

"Okay, start." He indicated Zhao Shilin.

Zhao Shilin took the bag, took out a bag of malt from the bag, he looked to the German Leo, and simultaneously showed Qin Dong translation. Deep problem, due to the use of pure malt brewing, the total nitrogen in the wheat sauce is higher than the rypthe with excipients, so the chromaticity of the malt should be 3.5 eBC-4.0EBC when selecting the raw pad of brewing. The acidity of malt is 14mll or less, it is best to use the library value at 39% -40% Australian malt ... "

"You translate to him ..." See Qin Dong himself picked up the malt to watch, Zhao Shilin urged.

"Mr. Reo said that the quality of raw rice malt is critical. In addition, the content of protein is lower. Does your malt have achieved the conditions you mentioned?"

Zhao Shilin laughed with confidence, he looked at the Zhongxing fire. "You told Leo, and he will definitely reach the standard I just said."

Qin Dong is also a scraper, but Zhao Shilin immediately said. "We use Australian malt, but yeast is the fundamental of beer fermentation, and the goodness of beer flavor depends to largely depending on the type and quality of bacteria, all malt beer. Should have the flavor of our Chinese people to accept ... "

"This is not worrying," Qin Dong looked at the Zhongxing fire, smiled, "a German yeast species, we can reach Qin Bay today, we will call him Shijucheng strain, fermented with this strain, flavor pure, Also have a very light type of beer specialty ... "

"This is good, the raw materials and strains have no problem, the rest is the process." Zhao Shilin is very happy, he looks at the Germans, this is the purpose of the joint venture, is to use foreign advanced technology.

However, this young man was once again, and he was very unhappy.

If there are other translations now, he will immediately leave him.

"There is also the control of the acidity during the saccharification," Zhao Shilin frowned, "This is the core part of the process."

Since it is the core part, the German will transfer technology to China. When he heard that the Germans promised to transfer the production license, this production license is the way? The way, his heart has no bottom.

The Leo has a big booth, and it has been a big German.

"Mr. Reo said that the acidity of beer mainly comes from three aspects. Various organic acids produced by yeast metabolism, three is to regulate acid such as phosphate and lactic acid added pH during the saccharification process ... "

Zhao Shilin's emotions changed, Qin Dong said accurately, the nouns of various industrial beers, communication is very smooth, so that he is very happy.

"The young man is very good," he couldn't help but pat the shoulders of Qindong, "I don't do it."

Sun Huifang saw a glimpse, this is the factory manager of thousands of people!

Zhongxing quickly gave a round game, "Okay, the raw materials have, the principle is passed, we will do it."

......

The most important of all malt beer is the saccharification process, the ingredient ratio is 7500 kg of malt, 30 kg of wine.

Zhao Shilin personally defended in the saccharification workshop. For the concerns of Qin Dong's actual controller, Zhongxing fire excuses need to be confidential, the leadership team in the factory has not come, these people have seen Qindong. He doesn't want them to know the inside of the joint venture.

"What happened, is the Germans not very good?" Zhao Shilin looked at the watch and did not see the figure of the German outside.

"Come, come." Sun Huifeng, who has been in the right to coordinate, refers to the door, and Qin Dong, who wears a white cotton mask, walks in.

"Mr. Leo?" Zhao Shilin also hurriedly greeted, he didn't look at Qindong, but he looked at Qin Dong's body, but he had a foreigner.

"Mr. Leo ..." Through these days, the technical literacy of Leo is still good, but it is limited to the beer workshop, but this does not hinder him is a good actor, in front of Zhao Shilin, he will play the role of the engineer. Dreaming, "Mr. Leo is sick."

"What disease? Tight? How do you give this time?" Zhao Shilin immediately issued a series of questions.

Qin Dong was annoyed, Leo made a problem like a Zhongxing fire in the previous days.

Looking at Sun Huifang also invited Zhong Xinghuo, Zhao Shilin is more anxious, a young translation, unfair, he asked, "What happened in Leo?"

"He has acute gastroenteritis ..." This is due to the report, Qin Dong did not know, anyway, he got himself in it, personally perform it, "he can't come, so today, I will be responsible for the saccharification. Process. "

"Have you?" Zhao Shilin said that he would like to be Qin East up and down.
